jWeixin annotated

How WeChat's JS-SDK works. Reverse engineering of jWeixin.

Why

For all we known, WeChat is most popular social APP in China, and thousands of developers make thousands of interactive web pages depending on it's JS-SDK everyday.

But there is no detailed documentation about it's implementation, even a change log can't not be found, only a doc about how to use.

So I launch this project, for better known of how it works, and what have changed during it's iteration.

File naming

all .js files would be named as \d.\d.\d or \d.\d.\d.-annotated, the nummeric-only ones stands for JS-SDK's original version, and ones with -annotated suffix for none-uglified and annotated.

Version 1.2.0

The latest version of WeChat's JS-SDK.

What we know from it

Added APIs:

• consumeAndShareCard undocumented
• openEnterpriseRedPacket undocumented
• openEnterpriseChat undocumented
• startSearchBeacons
• stopSearchBeacons
• onSearchBeacons
• openAddress

Added feature: Local resources (iOS only)

iOS version loads local resources by callling wx.getLocalImageData, and Android should have native implementation for it.

fixed: wx.error would be called only once

update: clientInfo.preVerifyState => clientInfo.isPreVerifyOk

Version 1.0.0

What we know from it

OPTIONS.check for stats tracking

WeChat would track your clientInfo when passing true to options.checktrue during wx.config.
