Question

这是我的登录API，我想登录该应用程序。

 private void attemptLogin(final String email,final String password) {

     Retrofit retrofit = new Retrofit.Builder()
             .addConverterFactory(GsonConverterFactory.create())
             .baseUrl(BaseUrl)
             .build();
     LoginApi service = retrofit.create(LoginApi.class);
     final User user = new User();
     user.setEmail(email);
     user.setPassword(password);

     final Call<List<User>> userCall = service.login(email,password);
             userCall.enqueue(new Callback<List<User>>() {
             @Override
              public void onResponse(Call<List<User>> call, Response<List<User>> response) {

                 Intent intent = new Intent(MainActivity.this, ProfileActivity.class);
                 startActivity(intent);
             }

         @Override
         public void onFailure(Call<List<User>> call, Throwable t) {

             Toast.makeText(MainActivity.this, " Fail to login ", Toast.LENGTH_SHORT).show();
         }

在 build.gradle 文件中添加以下行：

compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'

为api params创建一个公共接口：

例如。 @POST("api/auth")

Call<Auth> auth(@Field("username") String username, @Field("password") String password);

private void executeAuthEndpoint() {

    String _loginId = loginId.getText().toString();
    String _password = password.getText().toString();
    if (_loginId.length() > 0 && _password.length() > 0) {

        endpoint.auth(_loginId, _password).enqueue(new Callback<Auth>() {
            @Override
            public void onResponse(Call<Auth> call, Response<Auth> response) {

                if (response.isSuccessful() && response.body() != null && response.body().getStatus().equalsIgnoreCase("success")) {

                   // your code
                }
                else if (response.body()!=null && response.body().getMessage()!=null) {
                    Toast.makeText(getActivity(), response.body().getMessage(), Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity(), R.string.message_auth_fail, Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onFailure(Call<Auth> call, Throwable t) {
                if (call.isExecuted()) return;

                ErrorHandler.handleError(getActivity(), t);
            }
        });
    } else {
        Toast.makeText(getActivity(), R.string.message_empty_field, Toast.LENGTH_SHORT).show();
    }
}
