需要改造HTTP方法注釋

Question

我正在使用改造2.1，當我調用@GET時說

HTTP method annotation is required (e.g., @GET, @POST, etc.).

現在..如果我定義@ retrofit.http.GET它會拋出

No Retrofit annotation found. (parameter #1)

使用@POST可以，可以使用！

那是我的HTTP方法錯誤日志...

我的界面：

 import okhttp3.ResponseBody;
 import retrofit2.Call;
 import retrofit2.http.Field;
 import retrofit2.http.FormUrlEncoded;
 import retrofit2.http.GET; 
 import retrofit2.http.POST;
 import retrofit2.http.Query;


 public interface Testapi {


    @GET("/getq.php")
    Call<Testmodel> getquery(
            @Query("sort") String order
    );


    @FormUrlEncoded
    @POST("/insert.php")
    Call<ResponseBody> insert(
            @Field("nick") String nick,
            @Field("mail") String mail
    );

}

和方法

private void getjson() {
    //Creating a rest adapter

    RestAdapter adapter = new RestAdapter.Builder().setEndpoint(ROOT_URL).build();

    //Creating an object of our api interface
    Testapi api = adapter.create(Testapi.class);
    Call<Testmodel> call = api.getquery("a");

    call.enqueue(new Callback<Testmodel>() {
        @Override
        public void onResponse(Call<Testmodel> call, Response<Testmodel> response) {
            try {
                Testmodel obj = response.body();

                TextView txt = (TextView) findViewById(R.id.textView);
                txt.setText("ID: " + obj.getId() + "   nick: " + obj.getNick() + "   mail: " + obj.getMail());

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Call<Gitmodel> call, Throwable throwable) {
            Toast.makeText(SignIn.this, "FALLIMENTO",     Toast.LENGTH_LONG).show();
        }
    });

Answer 1

@POST注釋方法，必須具有參數，標記為@Body
例：

@POST("/user/mobile/verify")
VerifyCodeResponse verifyMobile(@Body VerifyRequest request);

Answer 2

首先，請檢查所有使用Retrofit的商品的進口。

在您的接口Testapi中，您使用Retrofit2，但是在您的方法getjson（）中，您正在創建retrofit.RestAdapter而不是retrofit2.Retrofit，這肯定是錯誤的。

請解決此問題，然后檢查其是否有效。

PS。 這是有關從reftrofit 1. *遷移到2. *的非常不錯的教程。 跟隨他們，一切都應該正常工作：

為什么不直接從Maven使用Retrofit2 Gradle依賴關系？ -例如像在附加鏈接中。
