我正在尝试从我的 Android 项目中删除 HttpClient api 并转换为使用 HttpURLConnection。

在旧的 API 中，我使用了 HttpRequestExecutor，在应用下载和上传时更改通知栏中的一些图标

this.httpclient = new DefaultHttpClient(httpParameters){
        @Override
        protected HttpRequestExecutor createRequestExecutor() {
            return new HttpRequestExecutor(){

                @Override
                protected HttpResponse doSendRequest(HttpRequest request,
                        HttpClientConnection conn, HttpContext http_context)
                                throws IOException, HttpException {

                    EventsBroadcaster.broadcastConnectionUploading(context);
                    return super.doSendRequest(request, conn, http_context);
                }

                @Override
                protected HttpResponse doReceiveResponse(
                        HttpRequest request, HttpClientConnection conn,
                        HttpContext http_context) throws HttpException,
                        IOException {

                    EventsBroadcaster.broadcastConnectionDownloading(context);
                    return super.doReceiveResponse(request, conn, http_context);
                }
            };
        }
    };

我怎样才能对 HttpURLConnection 做同样的事情？

`OkHttpClient 客户端 = 新 OkHttpClient();

    MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
    RequestBody body = RequestBody.create(mediaType, "Your Body");
    Request request = new Request.Builder()
            .url("Your url")
            .post(body)
            .addHeader("add as many add headers as u want")
            .build();
    client.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(@NotNull Call call, @NotNull IOException e) {
            //What should happen if failed
        }

        @Override
        public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {
            //what should happen if it is successful
        }
    }); `
