How to pass Map<String, String> parameters or object to POST request via Retrofit?
提问by piobab
I have a problem with passing Map parameters or object to Retrofit POST request.
我在将 Map 参数或对象传递给 Retrofit POST 请求时遇到问题。
I follow square, kdubb labstutorials and this threadand I couldn't figure it out.
我遵循square、kdubb labs教程和这个线程，但我无法弄清楚。
My current code which works:
我当前有效的代码：
public interface FacebookUser {
@FormUrlEncoded
@POST("/user/login-facebook")
void login(
@Field("fb_access_token") String fbAccessToken,
@Field("os") String os,
@Field("device") String device,
@Field("os_version") String osVersion,
@Field("app_version") String appVersion,
@Field("online") String online,
Callback<FacebookLoginUserResponse> callback
);
}
and code:
和代码：
RestAdapter restAdapter = new RestAdapter.Builder()
.setServer(requestMaker.getUrl())
.build();
FacebookUser facebookUser = restAdapter.create(FacebookUser.class);
facebookUser.login(getFbAccessToken(),
getString(R.string.config_os),
Info.getAndroidId(getBaseContext()),
Build.VERSION.RELEASE,
Info.getAppVersionName(getBaseContext()),
"" + 1,
new Callback<FacebookLoginUserResponse>() {
@Override
public void success(FacebookLoginUserResponse facebookLoginUserResponse, Response response) {
}
@Override
public void failure(RetrofitError retrofitError) {
}
});
When I try to use this interface I receive from server that parameters are missing:
当我尝试使用此接口时，我从服务器收到缺少参数的消息：
public interface FacebookUser {
@POST("/user/login-facebook")
void login(
@Body Map<String, String> map,
Callback<FacebookLoginUserResponse> callback
);
}
and map:
和地图：
HashMap<String, String> map = new HashMap<String, String>();
map.put("fb_access_token", getFbAccessToken());
map.put("os", "android");
map.put("device", Info.getAndroidId(getBaseContext()));
map.put("os_version", Build.VERSION.RELEASE);
map.put("app_version", Info.getAppVersionName(getBaseContext()));
map.put("online", "" + 1);
Questions:What is it wrong? How can I pass object to request?
问题：怎么了？如何将对象传递给请求？

Well, now we can implement this thing (version 1.5.0).
好吧，现在我们可以实现这个东西（版本 1.5.0）。
@FormUrlEncoded
@POST("/oauth/access_token")
void getToken(
@FieldMap Map<String, String> params,
Callback<FacebookLoginUserResponse> callback
);

This feature is still not supported by the Retrofit 1.2.2, however you can compile your own version from the master branch with this feature or wait for the next release.
Retrofit 1.2.2 仍然不支持此功能，但是您可以使用此功能从主分支编译您自己的版本或等待下一个版本。

In retrofit 2.0 you have to do this way:
在改造 2.0 中，您必须这样做：
@FormUrlEncoded
@POST(Constant.API_Login)
Call<UserLoginPost> userLogin(@FieldMap Map<String, String> params);
