需要改造 HTTP 方法注解

Question

我正在使用改造 2.1，当我调用 @GET 时，它说

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

现在.. 如果我定义 @retrofit.http.GET 它会抛出

No Retrofit annotation found. (parameter #1)

使用@POST 没关系，它的工作原理！

这是我的 HTTP 方法的错误日志...

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
    );

}

还有方法

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

首先请检查您在所有使用 Retrofit 的类中的导入。

在您的接口 Testapi 中，您使用了 retrofit2，但在您的方法 getjson() 中，您创建的是 retrofit.RestAdapter 而不是 retrofit2.Retrofit，这绝对是错误的。

请解决此问题并检查它是否正常工作。

PS。这是关于从 reftrofit 1.* 迁移到 2.* 的非常好的教程。跟随他们，一切都应该正常工作：

为什么不直接从maven 使用retrofit2 gradle 依赖呢？ - 例如在附加链接中。

Answer 2

@POST注解方法，必须有参数，标记为@Body
示例：

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