据我所知，我得到了这个问题，因为我的代码出错了，但我可以找到正确的理由
有我的代码
auto-close=outsideClick我收到了这样的错误消息
public class MainActivity extends AppCompatActivity {
private MyServerConnection connection;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String URL = ...;
final Retrofit retrofit = new Retrofit.Builder()
.baseUrl(URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
connection = retrofit.create(MyServerConnection.class);
}
interface MyServerConnection {
@POST("/appreg")
Call<JSONObject> postWithJson(@Body JSONObject object);
}
public void test(View view) {
Log.e("TAG", "---!!! TEST !!!---");
final Call<JSONObject> call = connection.postWithJson(getJson());
call.enqueue(new Callback<JSONObject>() {
@Override
public void onResponse(Call<JSONObject> call, Response<JSONObject> response) {
Log.e("Response status code: ", String.valueOf(response.code()));
// isSuccess is true if response code => 200 and <= 300
if (response.isSuccessful()) {
Log.e("response body : ", response.body().toString());
} else {
try {
Log.e("response body error : ", response.errorBody().string());
here i get NULL ---> Log.e("!!!-- response body : ", " " + response.body());
} catch (IOException ignored) {
}
}
}
@Override
public void onFailure(Call<JSONObject> call, Throwable t) {
Log.e("TAG", "---!!! ERROR !!!--- : " + t.getMessage());
}
});
}
private JSONObject getJson() {
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("key", "val");
} catch (JSONException e) {
e.printStackTrace();
}
return jsonObject;
}
这很奇怪，因为如果我在浏览器中放入一个URL，我会回复标准回复

Using the URLconf defined in <code>APIGW.urls</code>,
Django tried these URL patterns, in this order:
</p>
<ol>
<li>
^gcm/
</li>
<li>
^web/
</li>
<li>
^app/
</li>
</ol>
<p>The current URL, <code>appreg</code>, didn't match any of these.</p>
</div>
<div id="explanation">
<p>
You're seeing this error because you have <code>DEBUG = True</code> in
your Django settings file. Change that to <code>False</code>, and Django
will display a standard 404 page.
</p>
</div>
</body>
</html>
我如何使用我的应用获得相同的标准消息？
我做错了什么？
答案 0 :(得分：2)
最终，由于/
我在/中将此.baseUrl(URL)标记在URL的末尾，我也将其放在方法@POST("/appreg")中...
当我从像@POST("appreg")这样的方法中删除它时，它开始工作

翻新2，
在基本URL的末尾和端点URL的末尾给出/时，将在响应中生成空响应404。因此，我坚持使用/ 位于基本URL 上对我有用，希望对您也有用。 ：）
答案 2 :(得分：0)
在我的情况下，问题是 @Path 。
我正在做类似下面的事情。
@Headers("Content-Type:application/json")
@GET("{remaningUrl}")
Call<String> postWithJson(@Header("Authorization") String authorization,@Path String remaningUrl);
使用 @Url
解决@Headers("Content-Type:application/json")
@GET
Call<String> postWithJson(@Header("Authorization") String authorization,@Url String remaningUrl);
