我正在寻找一种解决方案来定义一个唯一的 header 以在所有请求中使用。今天我使用 @Header 每个请求确实传递了类似参数，但我只想定义适用于所有请求的 header 而不需要像参数一样传递，例如在我的请求中修复此 header @ GET 和 @POST

今天我用这个。请注意，每个请求 @GET 我都需要将 Header 定义为参数。

//interface
@GET("/json.php")
void getUsuarioLogin(   
                        @Header("Authorization") String token,
                        @QueryMap Map<String, String> params,
                        Callback<JsonElement> response
                    );

//interface
@GET("/json.php")
void addUsuario(    
                        @Header("Authorization") String token,
                        @QueryMap Map<String, String> params,
                        Callback<JsonElement> response
                    );


//using
public void getUsuarioLogin(){
        Map<String, String> params = new HashMap<String, String>();         
        params.put("email", "me@mydomain.com");
        params.put("senha", ConvertStringToMD5.getMD5("mypassword"));           

        RestAdapter adapter = new RestAdapter.Builder()
                                .setLogLevel(RestAdapter.LogLevel.FULL)
                                .setEndpoint(WebServiceURL.getBaseWebServiceURL())                              
                                .build();

        UsuarioListener listener = adapter.create(UsuarioListener.class);
        listener.getUsuarioLogin(
                                      //header  
                                      "Basic " + BasicAuthenticationRest.getBasicAuthentication(),
                                      params, 
                                      new Callback<JsonElement>() {         
            @Override
            public void success(JsonElement arg0, Response arg1) {
                Log.i("Usuario:", arg0.toString() + "");                
            }

            @Override
            public void failure(RetrofitError arg0) {
                Log.e("ERROR:", arg0.getLocalizedMessage());

            }
        }); 

    }





//using
    public void addUsuario(){
            Map<String, String> params = new HashMap<String, String>();
            params.put("name", "Fernando");
            params.put("lastName", "Paiva");

            RestAdapter adapter = new RestAdapter.Builder()
                                    .setLogLevel(RestAdapter.LogLevel.FULL)
                                    .setEndpoint(WebServiceURL.getBaseWebServiceURL())                              
                                    .build();

            UsuarioListener listener = adapter.create(UsuarioListener.class);
            listener.addUsuario(
                                          //header  
                                          "Basic " + BasicAuthenticationRest.getBasicAuthentication(),
                                          params, 
                                          new Callback<JsonElement>() {         
                @Override
                public void success(JsonElement arg0, Response arg1) {
                    Log.i("Usuario:", arg0.toString() + "");                
                }

                @Override
                public void failure(RetrofitError arg0) {
                    Log.e("ERROR:", arg0.getLocalizedMessage());

                }
            }); 

        }

最佳答案

官方文档:

Headers that need to be added to every request can be specified using a RequestInterceptor. The following code creates a RequestInterceptor that will add a User-Agent header to every request.

RequestInterceptor requestInterceptor = new RequestInterceptor() {
  @Override
  public void intercept(RequestFacade request) {
    request.addHeader("User-Agent", "Retrofit-Sample-App");
  }
};

RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("https://api.github.com")
.setRequestInterceptor(requestInterceptor)
.build();
