mPaas離線包之內網環境iOS客戶端白頁問題查看從入門到放棄

手機連不上內網已經解決了，

手機udid沒加也解決了。

不得不說mPaas把h5容器封裝的很死，即使完全知道本地h5如何在webview加載的，也很難查看其問題。

h5離線包只能加載從發佈平臺導出來的h5代碼，即使想改，自己也改不了，改了，也得在發佈平臺重新發布纔可以用。

如果是明文的h5自己就可以攔截替換一些文件，隨便加點代碼。

解決：修改h5代碼（加點彈窗），發佈h5代碼，可能需要很多次,查看哪行代碼沒有執行下去。在螞蟻的人不改客戶端的情形下。

混淆後的一個js文件有300k,900k，xcode打開都直接卡死。

下面是客戶端能看到的混淆後的js小部分

客戶端調用方法有限。

通過控制檯的打印：在加載h5包時會有一些日誌打印發現了兩點

1.行爲分析的外網js，通過MyConnectionURLProtocol攔截到外網的js鏈接地址，然後從整個工程掃描這個地址，發現是行爲分析的framework裏面的。

把他關掉：NBLogConfigurationGet().shouldInjectSPMJS = NO;

2.長鏈接：通過c語言hook系統日誌打印方法nslog發現有幾個日誌是[DTLongLinkDataDispatch cmdTimeout:]打印出來的。

然後把他也關掉 [MySyncService sharedInstance]這個方法註釋掉。

再然後控制檯沒有什麼有用信息了。

開始的時候又寫了一個MyConnectionURLProtocol。想攔截處理，但是螞蟻內部已經有了一個PSDWebViewURLProtocol，這樣兩個都會走。那就把PSDWebViewURLProtocol的方法都hook過來吧

這些代碼添加後能夠走進來，對A功能的h5離線包也能正常打開。

但是對於一直白屏的B功能，還是白屏，而且要找的那個http請求沒有走到這裏。看來只能使用上面的方法解決。
