我需要向Retrofit 2.0.0-beta2库发出的每个请求添加查询参数。我为Retrofit 1.9找到了this solution,但是如何在最新的库版本中添加RequestInterceptor

我的界面:

@GET("user/{id}")
Call<User> getUser(@Path("id")long id);

@GET("users/")
Call<List<User>> getUser();

客户:
Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(CLIENT)  // custom OkHTTP Client
                    .build();
service = retrofit.create(userService.class);

最佳答案

为了完整起见,这是您需要使用OkHttp-Interceptor向每个Retrofit 2.x请求添加参数的完整代码:

OkHttpClient client = new OkHttpClient();

client.interceptors().add(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        HttpUrl url = request.url().newBuilder().addQueryParameter("name","value").build();
        request = request.newBuilder().url(url).build();
        return chain.proceed(request);
    }
});

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("...")
        .client(client)
        .build();
