来自服务器的响应如下:
{
success: true,
token: "someRandomToken"
}
如何从回复中检索token
?
我尝试按照here提供的解决方案,但我无法在onResponse Call
内部method
添加通用
修改
这是我的方法
public void loginUser(final Context context, String url, String username, String passowrd, loginJson loginjson) {
final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
loginjson.setUsername(username);
loginjson.setPassword(passowrd);
Gson gson = new Gson();
String jsonFromForm = gson.toJson(loginjson);
OkHttpClient client = new OkHttpClient();
RequestBody body = RequestBody.create(JSON, jsonFromForm);
Request request = new Request.Builder()
.url(url)
.post(body)
.addHeader("content-type", "application/json; charset=utf-8")
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
System.out.println("Failure!!");
}
@Override
public void onResponse(Call call, final Response response) throws IOException {
if(response.isSuccessful()) {
if (context != null) {
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
if(response.body() != null){
}
}
});
}
//
} else {
if (context != null) {
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
Toast.makeText(context, context.getResources().getString(R.string.failed_to_login),
Toast.LENGTH_SHORT).show();
}
});
}
}
}
});
}
实施@Piyush Patel后答案:
我将Call
和Response
分别更改为retrofit2.Call<tokenRetrieved>
和retrofit2.Reponse<tokenRetrieved>
。但我Callback
中的enqueue
提示错误,要求我实施其onResponse
和onFailure
方法
新手问题:我使用的是retrofit1
方法吗?!!

以下是一个片段,展示了如何使用GSON实现它
public class JsonResponse {
public String success;
public String token;
public JsonResponse(String success, String token) {
this.success = success;
this.token = token;
}
}
Call<JsonResponse> call = api.checkLevel(1);
call.enqueue(new Callback<JsonResponse>() {
@Override
public void onResponse(Call<JsonResponse> call, Response<JsonResponse> response) {
if (response.isSuccessful()) {
JsonResponse jsonResponse=response.body();
}
}
@Override
public void onFailure(Call<JsonResponse> call, Throwable t) {
}
});

你可以这样做吗?
试试此代码
public void onResponse(String response) {
try {
JSONObject object=new JSONObject(response);
if ((object.getBoolean("success"))==true){
String Token=object.getString("token");
}else{
// enter else condition
}
} catch (JSONException e) {
e.printStackTrace();
// json Exception
}
}

从您的回复字符串中创建JSONObject
并获取包含密钥token
的字符串
JSONObject json = new JSONObject(response);
json.getString("token");
