java - OkHttp 代理设置

Question

我必须使用 proxyHost 和 proxyPort 设置代理以使用 POST 发送 JSON。

public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  Proxy proxyTest = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("proxy", proxyPort));

  OkHttpClient client = new OkHttpClient()
  .proxy(proxyTest)
  .build();
  //OkHttpClient.Builder builder = new OkHttpClient.Builder();
  //builder.proxy(proxySAP);
  //client.setProxy(proxySAP)
  //OkHttpClient client = builder.build();;

  String post(String url, String json) throws IOException {

    RequestBody body = RequestBody.create(JSON, json);
    Request request = new Request.Builder()
        .url(url)
        .post(body)
        .build();
    try (Response response = client.newCall(request).execute()) {
      return response.body().string();
    }
  }

当我尝试使用我在此处的一些答案中看到的 proxyTest 时，它指出了一个错误:

The method proxy() in the type OkHttpClient is not applicable for the arguments (Proxy)

我正在使用 OKHTTP 3.3.1(okhttp3)

我的问题是，我该怎么办？我做了一些这样的测试:

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.proxy(proxyTest);
client.setProxy(proxyTest)
OkHttpClient client = builder.build();

但到目前为止没有任何效果。

感谢您的宝贵时间!

找到解决方案:

  OkHttpClient client = new OkHttpClient.Builder().proxy(proxyTest).build();

如果我们使用构建器输入代理，它会像魅力一样工作 =D
