Question

我想在我的Android应用程序中调用现有的Web Api服务，使用retrofit 2库进行登录。当我调试一切似乎没有问题，只是我的@POST行没有执行服务接口。我正在使用localhost，并使用chrome中的端口转发将端口转发到我的手机。

这是我的代码： RestService.class

    public class RestService {

    public static Retrofit retrofit = null;

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

ApiUtils.java

    public class ApiUtils {

    public static final String NService = "http://localhost:5108/NSureServices.svc/";

    public static Service getLoginDetails(){
        return RestService.getClient(NService).create(Service.class);
    }
}

Service.class

   public interface Service {

    @FormUrlEncoded
    @POST("GetLoginDetails")
    Call<User> login(@Field("USERID") String UserId, @Field("PASSWORD") String Password, @Field("apiKey") String ApiKey);

}

LoginActivity.class

    public class LoginActivity extends AppCompatActivity {

    EditText email, password;
    Button login;
    TextView register, forgotPassword;
    Service service;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        email = (EditText)findViewById(R.id.emailIdEt);
        password = (EditText)findViewById(R.id.passwordEt);
        register = (TextView)findViewById(R.id.signUpTv);
        forgotPassword = (TextView)findViewById(R.id.forgotPasswordTv);
        login = (Button)findViewById(R.id.loginBtn);
        service = ApiUtils.getLoginDetails();

        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                User user = new User();
                user.setUSERID(email.getText().toString());
                user.setPASSWORD(password.getText().toString());


                if(validateLogin(user.getUSERID(),user.getPASSWORD())){
                    doLogin(user.getUSERID(),user.getPASSWORD(),user.getApiKey());
                }

            }
        });

    }

    public boolean validateLogin(String UserId, String Password){
        if(UserId == null || UserId.trim().length() == 0){
            Toast.makeText(this, "Username is required", Toast.LENGTH_LONG).show();
            return false;
        }
        if(Password == null || Password.trim().length() == 0){
            Toast.makeText(this, "Password is required", Toast.LENGTH_LONG).show();
            return false;
        }
        return true;
    }



    public void doLogin(String uid, String pwd, String apikey){
        try {
            Call<User> call =service.login(uid, pwd, apikey);
            call.enqueue(new Callback<User>() {
                @Override
                public void onResponse(Call<User> call, Response<User> response) {
                    if(response.isSuccessful()){
                        Toast.makeText(LoginActivity.this, "Successful", Toast.LENGTH_LONG).show();
                    }
                    else{
                        Toast.makeText(LoginActivity.this, "Failure", Toast.LENGTH_LONG).show();

                    }
                }

                @Override
                public void onFailure(Call<User> call, Throwable t) {
                    Toast.makeText(LoginActivity.this, "Error", Toast.LENGTH_LONG).show();

                }
            });

        } catch (Exception ex){
            Toast.makeText(LoginActivity.this, ex.getMessage(), Toast.LENGTH_LONG).show();

        }

    }
}

我的依赖项：

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.squareup.retrofit2:retrofit:2.3.0'
    compile 'com.google.code.gson:gson:2.6.1'
    compile 'com.squareup.retrofit2:converter-gson:2.3.0'
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    provided 'org.glassfish:javax.annotation:10.0-b28'

    compile 'com.android.support:support-v4:26.+'
    testCompile 'junit:junit:4.12'
}

我已经在用户数据模型中定义了apikey。

你在网址的开头错过了斜线

您的网址应如下所示：

@POST("/GetLoginDetails/")

同样在您的依赖项中，您使用了support-v4和v7，这是不必要的。

support-v7包含v4支持库，因此您的依赖项中不需要compile 'com.android.support:support-v4:26.+'。

不要在依赖版本中使用+运算符。用户当前版本的支持库。

我的@POST语句没有在android中使用Retrofit 2执行
