🧹 Nitpick comments (23)
Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Method.cs (2)
1-17: LGTM! Consider future extensibility.The enum implementation is clean and well-documented. The choice of
POSTandPUTmethods is appropriate for file upload operations.Consider these enhancements for future extensibility:
- Add a default value to make the enum more robust:
public enum Method { + /// <summary> + /// Default method for file uploads. + /// </summary> + POST = 0, /// <summary> - /// The HTTP POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server. - /// </summary> - POST, - /// <summary> /// The HTTP PUT method is used to replace or update a current resource with new content. /// </summary> - PUT + PUT = 1 }
4-7: Enhance enum documentation with usage guidance.The current documentation clearly describes the purpose. Consider enhancing it with guidance on when to use each method for file uploads.
/// <summary> -/// Represents the HTTP method to be used with the request. +/// Represents the HTTP method to be used with the file upload request. +/// Use POST for uploading new files and PUT when replacing existing files at a specific URL. /// </summary>Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Options.cs (6)
21-23: Add input validation for username.Consider adding validation attributes to ensure the username is not empty and follows the correct format for Windows Authentication (domain\username).
[UIHint(nameof(Definitions.Authentication), "", Authentication.WindowsAuthentication, Authentication.Basic)] +[Required(ErrorMessage = "Username is required")] +[RegularExpression(@"^([^\\]*\\)?[^\\]+$", ErrorMessage = "For Windows Authentication, use domain\\username format")] public string Username { get; set; }
44-45: Add certificate thumbprint validation.Consider adding validation to ensure the certificate thumbprint follows the correct format.
[UIHint(nameof(Definitions.Authentication), "", Authentication.ClientCertificate)] +[RegularExpression(@"^[a-fA-F0-9]{40}$", ErrorMessage = "Invalid certificate thumbprint format")] public string CertificateThumbprint { get; set; }
51-52: Add range validation for timeout.Add validation to ensure the timeout value is within a reasonable range.
[DefaultValue(30)] +[Range(1, 3600, ErrorMessage = "Timeout must be between 1 and 3600 seconds")] public int ConnectionTimeoutSeconds { get; set; }
74-77: Fix typo in XML documentation.The word "successful" is misspelled in the documentation.
/// <summary> -/// Throw exception if return code of request is not successfull +/// Throw exception if return code of request is not successful /// </summary> /// <example>true</example>
65-71: Add default values for boolean properties.Consider adding default values for
AllowInvalidCertificateandAllowInvalidResponseContentTypeCharSetto make the behavior more predictable.+[DefaultValue(false)] public bool AllowInvalidCertificate { get; set; } /// <summary> /// Some API's return faulty content-type charset header. This setting overrides the returned charset. /// </summary> /// <example>false</example> +[DefaultValue(false)] public bool AllowInvalidResponseContentTypeCharSet { get; set; }
61-65: Add security warning in documentation.The
AllowInvalidCertificateoption can pose security risks. Consider adding a warning in the documentation./// <summary> /// Do not throw an exception on certificate error. +/// WARNING: Enabling this option may expose your application to man-in-the-middle attacks. +/// Use only in development or in controlled environments where self-signed certificates are necessary. /// </summary>Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Response.cs (3)
8-9: Consider making the Response class immutableTo ensure thread safety and prevent unintended modifications after the response is created, consider making the properties read-only by removing their setters and initializing them through the constructor.
public class Response { + public Response(string body, Dictionary<string, string> headers, int statusCode) + { + Body = body; + Headers = new Dictionary<string, string>(headers); + StatusCode = statusCode; + }
10-21: Consider adding content type handlingThe
Bodyproperty as a string might not be optimal for all response types (e.g., binary data, different encodings). Consider adding content type handling and appropriate type conversion.+ /// <summary> + /// The content type of the response body. + /// </summary> + public string ContentType { get; set; } /// <summary> /// The body of the response. + /// Note: For binary data, consider using byte[] instead of string. /// </summary> - public string Body { get; set; } + public object Body { get; set; }
37-41: Use HttpStatusCode enum for type safetyReplace the
inttype withSystem.Net.HttpStatusCodeenum to ensure only valid HTTP status codes are used.+using System.Net; /// <summary> /// The status code of the response, as an integer value. /// </summary> /// <example>200</example> - public int StatusCode { get; set; } + public HttpStatusCode StatusCode { get; set; }Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Authentication.cs (3)
1-6: Consider adding security-related documentation.While the basic documentation is good, consider adding security recommendations and best practices for each authentication method in the enum's main documentation. This would help developers make informed decisions about which authentication method to use.
Add additional XML documentation like this:
/// <summary> /// Represents the authentication method to be used with the request. /// </summary> +/// <remarks> +/// When choosing an authentication method, consider: +/// - Basic authentication should only be used over HTTPS +/// - WindowsAuthentication is recommended for intranet scenarios +/// - OAuth is recommended for public API access +/// - ClientCertificate provides strong security but requires certificate management +/// </remarks> public enum Authentication
28-31: Enhance OAuth documentation with token requirements.The OAuth documentation should specify what type of token is expected (Bearer, JWT, etc.) and any requirements for token management.
Enhance the documentation like this:
/// <summary> /// OAuth token-based authentication is used, where a token is obtained from an authentication server and used to authenticate the request. +/// The token should be a valid Bearer token. JWT tokens are recommended. +/// Ensure proper token lifecycle management including refresh and expiration handling. /// </summary>
33-36: Add certificate requirements to ClientCertificate documentation.The ClientCertificate documentation should specify the certificate requirements and format expectations.
Enhance the documentation like this:
/// <summary> /// Client certificate-based authentication is used, where a client certificate is used to authenticate the request. +/// Requires a valid X.509 certificate. The certificate must be installed in the certificate store +/// or provided as a .pfx/.p12 file with the private key. /// </summary>Frends.HTTP.UploadFile/Frends.HTTP.UploadFile.Tests/IntegrationTest.cs (2)
13-22: Consider improving test isolation and cleanup.Two suggestions for better test reliability:
- Consider using a random available port instead of hard-coding port 9191 to avoid potential conflicts in CI environments.
- Add a
[TearDown]method to properly dispose of the HTTP server.private IHttpServer _stubHttp; +private int _port; [SetUp] public void Setup() { - _stubHttp = HttpMockRepository.At("http://localhost:9191"); + _port = GetAvailablePort(); // Helper method to find free port + _stubHttp = HttpMockRepository.At($"http://localhost:{_port}"); } +[TearDown] +public void Cleanup() +{ + _stubHttp?.Dispose(); +}
32-49: Enhance test robustness and coverage.Consider the following improvements:
- Add explicit verification of response status code
- Add timeout handling for assertions
- Test with various encoding scenarios
var result = await UploadFileTask.UploadFile(input, options, CancellationToken.None); +Assert.That(result.StatusCode, Is.EqualTo(200)); + var request = _stubHttp.AssertWasCalled(called => called.Post("/endpoint")).LastRequest(); +Assert.That(request, Is.Not.Null, "Request was not received within timeout"); + var requestHead = request.RequestHead; var requestBodyByteArray = Encoding.GetEncoding(codePageName).GetBytes(request.Body); var requestContentType = requestHead.Headers["cONTENT-tYpE"]; -//Casing should not affect setting header. +// Verify header case-insensitivity and content Assert.That(requestContentType, Is.EqualTo(expectedContentType)); Assert.That(requestBodyByteArray, Is.EqualTo(utf8ByteArray)); + +// Verify response encoding +Assert.That(result.Content, Does.Contain("���"), "Response should preserve special characters");Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Header.cs (1)
11-17: Properties should be initialized to avoid null valuesThe
NameandValueproperties may be null if not set, which can causeNullReferenceExceptionwhen used. Consider initializing them with empty strings or adding null checks where they are used.Apply this diff to initialize properties:
public class Header { - public string Name { get; set; } + public string Name { get; set; } = string.Empty; - public string Value { get; set; } + public string Value { get; set; } = string.Empty; }Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/HttpClientHandlerExtensions.cs (2)
24-28: Improve parsing of domain and usernameSplitting the username on '\' might fail if the username contains a backslash or if the domain is missing. Consider using a more robust method to parse domain and username and handle cases where the domain is not provided.
Apply this diff to improve parsing:
case Authentication.WindowsAuthentication: - var domainAndUserName = options.Username.Split('\\'); - if (domainAndUserName.Length != 2) + var separatorIndex = options.Username.IndexOf('\\'); + if (separatorIndex <= 0) { throw new ArgumentException($@"Username needs to be in the format 'domain\username', but it was '{options.Username}'"); } - handler.Credentials = new NetworkCredential(domainAndUserName[1], options.Password, domainAndUserName[0]); + var domain = options.Username.Substring(0, separatorIndex); + var username = options.Username.Substring(separatorIndex + 1); + handler.Credentials = new NetworkCredential(username, options.Password, domain); break;
54-54: Throw a more appropriate exception when the certificate is not foundThrowing a
FileNotFoundExceptionmay not accurately represent the issue. Consider throwing aCryptographicExceptionor a custom exception to indicate that the certificate was not found.Apply this diff to throw a more specific exception:
- throw new FileNotFoundException($"Certificate with thumbprint: '{thumbprint}' not found in current user cert store."); + throw new CryptographicException($"Certificate with thumbprint '{thumbprint}' not found in the current user's certificate store.");.github/workflows/UploadFile_build_and_test_on_main.yml (1)
7-8: Consider adding package.json to path filters.The path filter correctly watches the main directory. Consider also watching package-related files that might affect the build.
paths: - "Frends.HTTP.UploadFile/**" + - "Frends.HTTP.UploadFile/package.json" + - "Frends.HTTP.UploadFile/package-lock.json"Frends.HTTP.UploadFile/README.md (2)
11-15: Improve installation instructions and URL formatting.The installation section needs the following improvements:
- Format the MyGet URL as a proper Markdown link
- Add version compatibility information
- Include step-by-step UI installation instructions
Apply this diff to fix the bare URL:
-https://www.myget.org/F/frends-tasks/api/v2. +[https://www.myget.org/F/frends-tasks/api/v2](https://www.myget.org/F/frends-tasks/api/v2)🧰 Tools

Bare URL used(MD034, no-bare-urls)
16-28: Enhance building instructions with prerequisites and context.The building section should include:
- Required tools and versions (.NET 6.0, etc.)
- Development environment setup steps
- Explanation of what each command does
- Location where the NuGet package will be generated
Frends.HTTP.UploadFile/Frends.HTTP.UploadFile/Definitions/Input.cs (1)
4-36: Security Advisory: Implement comprehensive security measures.This class handles sensitive operations (file uploads and HTTP requests) and requires thorough security implementation:
URL Security:
- Implement allowlist/blocklist for domains
- Validate URL schemes (e.g., prevent file:// URLs)
- Consider using
Uriclass for parsingFile Security:
- Implement file type validation
- Set maximum file size limits
- Use secure file handling practices
Header Security:
- Prevent header injection
- Validate header names and values
- Consider using a predefined set of allowed headers
Consider creating a separate security configuration class to centralize and manage these security measures.

input.Method.ToString()correctly converts the HTTP method enum to the appropriate string value accepted byHttpMethod.If
input.Methodis an enum, confirm that itsToString()method returns standard HTTP method names like "GET", "POST", etc.
93-103: Ensure proper addition of headers to request and contentWhile adding headers, the current approach may not add headers as expected if they are restricted. It's important to verify whether headers are correctly assigned to either the request or content headers.
Please run the following script to check headers added to the request:
✅ Verification successful
Headers are properly handled with fallback mechanism
The current implementation correctly handles header addition by:
- Attempting to add to request headers first
- Falling back to content headers if request headers fail
- Using TryAddWithoutValidation to handle restricted headers
- Providing appropriate warning messages for debugging

🛠️ Refactor suggestion
Use case-insensitive dictionary for headers
HTTP headers are case-insensitive. Use Dictionary<string, string>(StringComparer.OrdinalIgnoreCase) to ensure proper header matching.

💡 Codebase verification
The review comment is accurate - test coverage needs significant improvement
The implementation has error handling for several scenarios that are currently untested:
- HTTP error responses (ThrowExceptionOnErrorResponse option)
- Authentication with domain\username format
- Certificate handling and validation
- File not found scenarios
Additionally, the suggested scenarios from the review (large files, different content types, error scenarios, cancellation) are also missing.
🔗 Analysis chain
Consider adding more test scenarios.
The current test covers the basic case, but consider adding tests for:
- Large file uploads to verify streaming behavior
- Different content types (e.g., binary files, images)
- Error scenarios (network timeout, server errors)
- Cancellation token handling

💡 Codebase verification
Critical security validations needed for file handling
The implementation confirms the need for security measures. Current code reads files without any validation, potentially exposing several vulnerabilities:
- No path traversal protection
- Missing file existence validation
- Loads entire file into memory without size limits (potential DoS)
- No file access permission checks
The suggested property validations and runtime checks are necessary. Additionally, consider:
- Implementing streaming for large files instead of
File.ReadAllBytes - Adding configurable file size limits
- Validating file existence before attempting to read
🔗 Analysis chain
Add critical security validations for file path.
The FilePath property requires validation to prevent security vulnerabilities like path traversal and to ensure proper file handling.
/// </summary>
/// <example>C:\Users</example>
+ [Required(ErrorMessage = "File path is required")]
+ [RegularExpression(@"^[^<>:""/\\|?*]+$", ErrorMessage = "File path contains invalid characters")]
+ [StringLength(260, ErrorMessage = "File path exceeds maximum length")]
public string FilePath { get; set; }Additionally, implement runtime validation in the task execution to:
- Verify file existence
- Check file size limits
- Validate file permissions
- Prevent path traversal attacks

50-50: Use asynchronous file operationsFor consistency and to prevent blocking the thread, consider using the asynchronous method
ReadAllBytesAsyncwhen reading the test file.Apply this diff:
- var utf8ByteArray = File.ReadAllBytes(testFilePath); + var utf8ByteArray = await File.ReadAllBytesAsync(testFilePath);Ensure the test method is marked with
asyncand any necessary changes are made to accommodate the asynchronous call.
47-188: Extend test coverage to include additional scenariosWhile the current tests cover basic functionality and some authentication methods, consider adding tests for the following scenarios to improve test coverage:
- Large file uploads: Test uploading large files to verify that the upload process handles large data streams correctly.
- Different content types: Test uploading files with different content types (e.g., binary files, images) to ensure that content type headers and encoding are handled properly.
- Error scenarios: Include tests for network timeouts, server errors, and other failure modes to ensure that the task handles errors gracefully.
- Cancellation token handling: Add tests to verify that the operation correctly responds to cancellation requests via the
CancellationToken.
139-140:⚠️ Potential issueVerify the format of the Windows Authentication username
The username for Windows Authentication should typically be in the format
domain\\username. Currently, it is set asUsername = "user\\domain", which appears to be reversed.Please verify that the username is correctly formatted and that the authentication works as expected.

💡 Codebase verification
Certificate cleanup is missing from test implementations
The test code adds certificates to the CurrentUser store but doesn't clean them up:
- No certificate removal from store in test cleanup methods
- Only file system cleanup is implemented
- Certificates remain in the user's store even after tests complete
Recommendations:
- Add certificate store cleanup in test cleanup methods using
store.Remove(cert) - Consider using a dedicated test store location
- Track certificate thumbprints for cleanup
🔗 Analysis chain
Review security implications of test certificates.
While this is test code, there are several security considerations to be aware of:
- Certificates are created with exportable private keys
- Certificates are stored in the user's certificate store
- The cleanup process is critical to prevent certificate accumulation
Consider adding a finally block to ensure cleanup runs even if tests fail.
