Retrofit GsonConverterFactory 解析带有转义符的数据

[KKaKa]

• 后台返回的数据：

{
    "code": "00",
    "mobileData": "[{\"publish_type\":\"00\",\"uv_value\":3,\"app_type\":\"02\",\"page_type\":\"\",\"customer_level\":\"ALL_CUSTOMER\",\"partner_level\":\"0\",\"rule_number\":0,\"click_number\":0,\"title\":\"超时\",\"create_operator\":\"zexin\",\"publish_operator\":\"wangchaocheng\",\"optimistic\":0,\"update_time\":\"2019-03-20 14:28:43\",\"pv_value\":10,\"publish_time\":\"2019-03-20 14:28:51\",\"link_url\":\"https://www.cnblogs.com/ailiailan/p/7388784.html\",\"id\":32,\"click_type\":\"H5\",\"create_time\":\"2019-02-26 09:36:33\",\"end_time\":\"2019-03-30 10:00:04\",\"link_title\":\"CNBLOGS\",\"message_type\":\"02\",\"optimistic_lastsync\":0,\"update_operator\":\"wangchaocheng\",\"start_time\":\"2019-02-25 09:36:01\",\"image_path\":\"http://.www.baidu.com\",\"popup_rule\":\"02\",\"region\":\"\",\"status\":\"NORMAL\"}]",

• api代码：

    @POST(ACTION)
    @FormUrlEncoded
    Observable<ResponseBean<AdBaseBeanList>> getAds2(
            @Field("requestType") String requestType,
            @Field("encryptData") String encryptData,
            @Field("signature") String signature,
            @Field("validate") boolean validate
    );

• retrofit代码：

            apiService.getAds2(Constant.PUSH_MESSAGE_HANDLE,encrypt,sign,true)
                    .map(new BaseFunc1<>())
                    .subscribeOn(Schedulers.io())
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(observe);

比较笨的方法可以把 AdBaseBeanList 改成 String，数据接收到之后 用gson在转一下。

感谢。 是的，这也是我目前采用的 ，但感觉很不舒服，既然我用了GsonConverterFactory，就势必想要一步到位，直接返回bean。我试图重写Converter但没有成功，我希望通过重写Converter来解决这个问题。

这很明显是后端同学偷懒的结果，json 写成这样...我觉得与其在端上妥协，做这种 trick 的处理。还不如跟后端沟通一下，给过来标准的 json 格式。 另外我觉得 @bricklazy 提到的处理方式是最简单有效的。其实你也已经用了 RxJava，只需要再 map 一次就 ok 了。重写 Converter 就复杂了，而且也不通用。
