java–Retrofit：500内部服务器错误

每当我尝试通过Retrofit发送POST请求时,我有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>() {
@Override
public void success(List 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> response);


邮递员的请求和回复的例子：

解决方法:

似乎在postman中你发送了一个FriendModel数组,但在你的代码中你发送的是一个对象.

只需更改您要发送的对象,而不是发送单个对象,发送服务器所需的List

List friendsList = new ArrayList();
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> response);


至

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