Question

每次我尝试通过Retrofit发送POST请求时，我都有500个内部服务器错误。当我发送GET请求时，它正确发送。我确信在服务器端，每一件事都可以。我的代码出了什么问题？

    String ENDPOINT = "http://52.88.40.210";
    //model for request
        FriendModel ff = new FriendModel();
        ff.setFriendNumber("380935275259");
        ff.setId(516);
        ff.setNumber("380936831127");

        RestAdapter adapter = new RestAdapter.Builder()
                .setEndpoint(ENDPOINT)
                .build();
        WayfAPI api = adapter.create(WayfAPI.class);
        api.getFriendsLocation(ff, new Callback<List<FriendLocationModel>>() {
            @Override
            public void success(List<FriendLocationModel> friendLocationModels, Response response) {
                for (FriendLocationModel ff : friendLocationModels) {
                    Log.d("myLogs", "===========Successful==========");
                    Log.d("myLogs", "Id: " + ff.getId());
                    Log.d("myLogs", "Number: " + ff.getNumber());
                    Log.d("myLogs", "GeoLocation: : " + ff.getGeoLocation());
                }
            }

            @Override
            public void failure(RetrofitError error) {
                Log.d("myLogs", "-------ERROR-------");
                Log.d("myLogs", Log.getStackTraceString(error));
            }
        });
    }

请求声明：

@Headers({
        "Accept: application/json",
        "Content-type: application/json"
})
@POST("/api/geo/getLoc")
public void getFriendsLocation(@Body FriendModel friendModel, Callback<List<FriendLocationModel>> response);

邮递员的请求和回复的例子：

似乎在邮递员中你发送了一个FriendModel数组，但在你的代码中你发送了一个单独的对象。

只需更改您要发送的对象，而不是发送单个对象，发送服务器期望的列表

    List<FriendModel> friendsList = new ArrayList<FriendModel>();

    FriendModel ff = new FriendModel();
    ff.setFriendNumber("380935275259");
    ff.setId(516);
    ff.setNumber("380936831127");

    friendsList.add(ff);

您还应该更改此签名：

public void getFriendsLocation(@Body FriendModel friendModel, Callback<List<FriendLocationModel>> response);

到

public void getFriendsLocation(@Body List<FriendModel> friendModel, Callback<List<FriendLocationModel>> response);

改造：500内部服务器错误
