阿里系大多使用了MTOP来加签请求，所以需要通过hook的方式关掉这个加签。我这里使用的是xposed。也可以使用Frida

 @Override
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
        XposedBridge.log("========START=====");

if(lpparam.packageName.contains("com.taobao")){
            XposedUtil.checkXposed(lpparam);
            XposedHelpers.findAndHookMethod(XposedHelpers.findClassIfExists("mtopsdk.mtop.global.SwitchConfig", lpparam.classLoader), "isGlobalSpdySwitchOpen",
                    new XC_MethodHook() {
                protected void afterHookedMethod(MethodHookParam methodHookParam) throws Throwable {
                    super.afterHookedMethod(methodHookParam);
                    XposedBridge.log("========开启抓包=====");
                   methodHookParam.setResult(false);
                }
            });
}
}

Charles设置抓包HTTPS，打开淘宝，就能在Charles看到请求了

抓包淘宝
