Question

这似乎是一个非常简单的问题，但我无法弄清楚。我调用的API在Postman中工作正常，并构成了App的iOS版本。只是Android让我很健康。可能还不够咖啡。我正在使用Android Studio进行最新更新。

API接受一个长URL作为JSON主体，并返回一个shortURL作为字符串。

RetrofitInterface.java

private void getShortURL() {
    //Get full url
    final String fullURL = Constants.SHARE_BASE_URI + urlParameters;

    //Convert URL to JSON formatted data
    Map<String,String> data = new HashMap<String,String>();
    data.put("URL",fullURL);
    String jsonData = new GsonBuilder().create().toJson(data,Map.class);

    //Call API and pass in JSON to get Short URL
    Call<ResponseBody> getDynamicLinkCall = RetrofitAdapter.getRetroInterface(Constants.BASE_URI).getDynamicLink_String(Constants.getTimestamp(),Constants.APPLICATION,"application/json", jsonData);

    getDynamicLinkCall.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response == null ||  response.code() != Constants.SUCCESS) {
                //Share Short URL
                share(response.body().toString());
            }
            else
            {
                //If Short URl Failed share long URL
                share(fullURL);
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            //If Short URl Failed share long URL
            share(fullURL);
        }
    });
}

改装适配器代码：

@POST("URLShortner")
Call<ResponseBody> getDynamicLink_String(@Header("TimeStamp") String timestamp, @Header("Application") String application, @Header("Content-Type") String contentType, @Body String jsonData);

我错过了什么？

提前致谢！

好的，我们发现了这个问题。我们错过了以下代码行：

RequestBody body = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),jsonObject.toString());

此代码在POST调用之前进入，而不是发布jsonData，我们发布了修复它的正文。希望Android Studio提供某种错误来暗示这一点。

完整方法：

private void getShortURL() {
    //Get full url
    final String fullURL = Constants.SHARE_BASE_URI + urlParams;

    //Convert URL to JSON formatted data
    Map<String,String> data = new HashMap<String,String>();
    data.put("LINK",fullURL);
    String jsonData = new GsonBuilder().create().toJson(data,Map.class);

    RequestBody body = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"), jsonData);

    //Call API and pass in JSON to get Short URL
    Call<String> getDynamicLinkCall = RetrofitAdapter.getRetroInterface(Constants.BASE_URI).getDynamicLink_String(Constants.getTimestamp(),Constants.APPLICATION,"application/json", body);

    getDynamicLinkCall.enqueue(new Callback<String>() {
        @Override
        public void onResponse(Call<String> call, Response<String> response) {
            if (response == null ||  response.code() != Constants.SUCCESS) {
                //Share Short URL
                share(response.body().toString());
            }
            else
            {
                //If Short URl Failed share long URL
                share(fullURL);
            }
        }

        @Override
        public void onFailure(Call<String> call, Throwable t) {
            //If Short URl Failed share long URL
            share(fullURL);
        }
    });
}

<强> RetrofitINterface.java：

@POST("URLShortner")
Call<String> getDynamicLink_String(@Header("TimeStamp") String timestamp, @Header("Application") String application, @Header("Content-Type") String contentType, @Body RequestBody jsonData);

全部谢谢！
