android - Retrofit 2 需要 HTTP 方法注解(如@GET、@POST 等)

Question

我的 Retrofit 配置有什么问题？当我使用 OkHttpClient 添加基本身份验证时出现此错误，但是当我使用没有拦截器的默认客户端时它正在工作。还是我的 Gradle 依赖项有问题......？

E/AndroidRuntime﹕ FATAL EXCEPTION: main
        java.lang.IllegalArgumentException

这是我要调用的 API 服务

  @GET("Triu-services-portlet.regaccrdetails/get-all-reg-accr-details-by-num-branch-code/num/{num}/branch-code/{branch-code}")
    public Observable<List<RegAccrDetails>> getRegAccrDetails(@Path("num") String num, @Path("branch-code")String branchCode);

我的 OkHttpClient 拦截器

private static OkHttpClient createOkHttpClient() {
   String username = "test@liferay.com";
   String password = "TEST";
   String credentials = username + ":" + password;
   final String basic =
           "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT);//no_wrap



    OkHttpClient client = new OkHttpClient();
    client.interceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Response response = chain.proceed(chain.request());

            Request original = chain.request();

            // Customize the request
            Request request = original.newBuilder()
                    .header("Authorization", basic)
                    .header("Accept", "application/json")
                    //.header("Authorization", "auth-token")//add token for service A4oslsSXZxfbLdk
                    .method(original.method(), original.body())
                    .build();

            response = chain.proceed(request);

            // Customize or return the response
            return response;
        }
    });

   return client;
}

这是我的 API 调用

private void liferayAccess(){
    Log.d("liferayAccess", "Entered");
    APIService service =  ServiceGenerator.createService(APIService.class);
    Observable<List<RegAccrDetails>> liferayResponse = service.getRegAccrDetails("004589209", "001");

    liferayResponse.subscribeOn(Schedulers.newThread()).map(listResponse -> "response index 0 " + listResponse.get(0).getRegNum())
            .subscribe( response-> Log.d("Liferay Num", response),
                        error -> Log.d("Error", error.toString())
                    );
}

My Proguard. I also tried add and remove it but same error log happen

-keepattributes *Annotation*
-keep class retrofit.** { *; }
-keepclasseswithmembers class * {
@retrofit.http.* <methods>; }
-keepattributes Signature


-keep class com.google.gson.** { *; }
-keep class com.google.inject.** { *; }
-keep class org.apache.http.** { *; }
-keep class org.apache.james.mime4j.** { *; }

-keep class retrofit.** { *; }

Answer 1

使用错误的“@GET”

这可能对来自 retrofit1 的人有所帮助，我遇到了同样的错误，修复很简单。在我的界面中，我没有意识到我使用的是来自 retrofit.http 的 @GET 而不是来自 retrofit2.http 的 @GET，我需要做的就是将注释从 retrofit.http 更改为 retrofit2.http。
