1.抓包代码

XposedBridge.hookAllConstructors(XposedHelpers.findClass("com.sankuai.meituan.retrofit2.Response", SharedObject.loadPackageParam.classLoader), new XC_MethodHook() {
            @Override
            protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                try {
                    Map<String, Object> request = Maps.newHashMap();
                    request.put("url", param.args[0]);
                    request.put("resp", param.args[4] == null ? "" : param.args[4].toString());
                    LogUtil.i("MEITUAN_HTTP", "#ClientCall Http Request#" + JSON.toJSONString(request));
                } catch (Exception e) {
                    Log.e("MEITUAN_HTTP", "#ClientCall Http Request# exception", e);
                }
            }
        });

2.OKHTTP降级开关

	public static com.sankuai.meituan.retrofit2.raw.RawCall.Factory a(java.lang.String str) {
        java.lang.Object[] objArr = {str};
        com.meituan.robust.ChangeQuickRedirect changeQuickRedirect = a;
        if (com.meituan.robust.PatchProxy.isSupport(objArr, null, changeQuickRedirect, true, "f3eb404c82ad0f34e256faed6da8654c", com.meituan.robust.utils.RobustBitConfig.DEFAULT_VALUE)) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) com.meituan.robust.PatchProxy.accessDispatch(objArr, null, changeQuickRedirect, true, "f3eb404c82ad0f34e256faed6da8654c");
        }
        if (str.equals("defaultokhttp")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) b.c();
        }
        if (str.equals("okhttp")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) c.c();
        }
        if (str.equals("nvnetwork")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) d.c();
        }
        if (str.equals("oknv")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) e.c();
        }
        if (str.equals("mapi")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) f.c();
        }
        if (str.equals("statistics")) {
            return (com.sankuai.meituan.retrofit2.raw.RawCall.Factory) g.c();
        }
        throw new java.lang.IllegalArgumentException("key:" + str + "not supported");
    }

3.Ctrip Hook抓包

// 请求

                new RC_MethodHook() {
                    @Override
                    protected void beforeHookedMethod(MethodHookParam methodHookParam) throws Throwable {
                        com.alibaba.fastjson.JSONObject jsonObject = null;
                        if (methodHookParam.args.length == 2) {
                            jsonObject = (com.alibaba.fastjson.JSONObject) JSON.toJSON(ForceFiledViewer.toView(methodHookParam.args[1]));
                        } else {
                            jsonObject = (com.alibaba.fastjson.JSONObject) JSON.toJSON(ForceFiledViewer.toView(methodHookParam.args[3]));
                        }
                        try {
                            String request = jsonObject.toJSONString();

                            LogcatUtil.i(TAG, realServiceCode);
                            // 酒店列表页接口的serviceCode
                            if ("17100101".equals(realServiceCode)) {
