这似乎是一个非常简单的问题，但我无法理解。我调用的API在Postman中运行良好，并形成了应用程序的iOS版本。只是安卓让我大吃一惊。咖啡可能不够。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，并返回一个短URL作为字符串

我错过了什么

提前谢谢

好的，我们发现了问题。我们缺少以下代码行：

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

这段代码在POST调用之前进入，我们没有发布jsonData，而是发布了修复它的主体。但愿Android Studio给出了某种错误来暗示这一点

完整方法：

    //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>() {

谢谢大家

这是唯一发生这种情况的情况吗？或者其他帖子也会这样吗？你能把你的护照寄出去吗？这是唯一的一种情况。这就是为什么如此令人沮丧。我将使用改装适配器更新OP。我们刚刚偶然发现了答案，将其发布在下面。谢谢你，路易斯！美好的但这很奇怪，它是如何与一些Android版本协同工作的，而不是与其他版本协同工作的。我很高兴你找到了答案。快乐编码；）
