翻新员额请求

Question

我想将用户凭据发送到以下url：http://myurl/authenticate

"login":{"username": "JohnDoe","password": "eoDnhoJ" }

{
" r e s u l t " : " S u c c e s s " ,
"response": "Users Session ID"
}

public interface APIService {

    @POST("/authenticate")
    @FormUrlEncoded
    Call<Login> savePost(@Field("username") String username,
                         @Field("password") String password);
}

public class ApiUtils {

    private ApiUtils() {}

    public static final String BASE_URL = "http://myurl/";

    public static APIService getAPIService() {

        return RetrofitClient.getClient(BASE_URL).create(APIService.class);
    }
}

@SerializedName("username")
@Expose
private String username;
@SerializedName("password")
@Expose
private String password;
//getters and setters
}

public class RetrofitClient {
    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl) {
        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}

public class LoginActivity extends AppCompatActivity {

    private EditText usernameEditText,passwordEditText;
    private Button button;
    private APIService mAPIService;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        usernameEditText=(EditText)findViewById(R.id.username);
        passwordEditText=(EditText)findViewById(R.id.password);
        button=(Button)findViewById(R.id.signup);

        mAPIService = ApiUtils.getAPIService();


        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String uname=usernameEditText.getText().toString();
                String pass=passwordEditText.getText().toString();
                if(TextUtils.isEmpty(uname)){
                    Toast.makeText(LoginActivity.this, "Username cannot be empty", Toast.LENGTH_SHORT).show();
                    return;
                }

                if(TextUtils.isEmpty(pass)){
                    Toast.makeText(LoginActivity.this, "Password cannot be empty", Toast.LENGTH_SHORT).show();
                    return;
                }

                if(pass.length()<4){
                    Toast.makeText(LoginActivity.this, "Password should be greater than four characters", Toast.LENGTH_SHORT).show();
                    return;
                }

                sendPost(uname, new StringBuilder(uname).reverse().toString());

            }
        });
    }


    public void sendPost(String username, String password) {
        mAPIService.savePost(username, password).enqueue(new Callback<Login>() {
            @Override
            public void onResponse(Call<Login> call, Response<Login> response) {

                if(response.isSuccessful()) {
                    showResponse(response.body().toString());
                    Log.i("Pritish", "post submitted to API." + response.body().toString());
                    Intent intent=new Intent(getApplicationContext(), MainActivity.class);
                    startActivity(intent);
                    finish();
                }
            }

            @Override
            public void onFailure(Call<Login> call, Throwable t) {
                Log.e("Pritish", "Unable to submit post to API.");
            }
        });
    }

    public void showResponse(String response) {
        Log.i("Abbu",response);
    }
}

而不是follwing代码

@POST("/authenticate")
@FormUrlEncoded
Call<Login> savePost(@Field("username") String username,
                     @Field("password") String password);

使用此代码

@POST("/authenticate")
Call<Login> savePost(@Query("username") String username,
                     @Query("password") String password);
