mPaas离线包之内网环境iOS客户端白页问题从入门到放弃
手机连不上内网已经解决了，
手机udid没加也解决了。
不得不说mPaas把h5容器封装的很死，即使完全知道本地h5如何在webview加载的，也很难查看其问题。
h5离线包只能加载从发布平台导出来的h5代码，即使想改，自己也改不了，改了，也得在发布平台重新发布才可以用。
如果是明文的h5自己就可以拦截替换一些文件，随便加点代码。
解决：修改h5代码（加点弹窗），发布h5代码，可能需要很多次,查看哪行代码没有执行下去。在蚂蚁的人不改客户端的情形下。
混淆后的一个js文件有300k,900k，xcode打开都直接卡死。
下面是客户端能看到的 混淆后的js小部分

客户端调用方法有限。
通过控制台的打印：在加载h5包时会有一些日志打印发现了两点
1.行为分析的外网js，通过MyConnectionURLProtocol拦截到外网的js链接地址，然后从整个工程扫描这个地址，发现是行为分析的framework里面的。
把他关掉：NBLogConfigurationGet().shouldInjectSPMJS = NO;
2.长链接：通过c语言hook系统日志打印方法nslog发现有几个日志是[DTLongLinkDataDispatch cmdTimeout:]打印出来的。
然后把他也关掉 [MySyncService sharedInstance]这个方法注释掉。
再然后控制台没有什么有用信息了。
开始的时候又写了一个MyConnectionURLProtocol。想拦截处理，但是蚂蚁内部已经有了一个PSDWebViewURLProtocol，这样两个都会走。那就把PSDWebViewURLProtocol的方法都hook过来吧

这些代码添加后能够走进来，对A功能的h5离线包也能正常打开。
但是对于一直白屏的B功能，还是白屏，而且要找的那个http请求没有走到这里。看来只能使用上面的方法解决。
重复上面的话：B功能的离线包正常打开，A功能的h5离线包白屏。
是不是想起来和客户端一点关系没有。
????????????????????????????????????????????????????????????????????????????????????????????????????????????????
学h5转h5去了。。。。。
客户端能做的也就这些了吧
