如何将代码从OkHttp转换为使用Apache Http？

Question

我正在努力在我的项目中获得一个返回200个答案的邮政请求。我们有一个邮递员测试，运行良好，并生成以下代码：

OkHttpClient client = new OkHttpClient().newBuilder()
  .build();
MediaType mediaType = MediaType.parse("text/plain");
RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
  .addFormDataPart("customerNumber","1000000")
  .addFormDataPart("username","razisami")
  .addFormDataPart("password","razisami1234")
  .build();
Request request = new Request.Builder()
  .url("http://localhost:8085/ImageGateway/login")
  .method("POST", body)
  .build();
Response response = client.newCall(request).execute();
'''
I need the same code written again to work with Apache HttpClient, see [Posting with HttpClient][1]

这是Apache HttpClient 5.1的等效代码，我建议在新项目中使用它来代替HttpClient 4.5

CloseableHttpClient httpclient = HttpClients.createSystem();
ClassicHttpRequest request = ClassicRequestBuilder.post()
        .setUri(new URI("http://localhost:8085/ImageGateway/login"))
        .addParameter("customerNumber","1000000")
        .addParameter("username","razisami")
        .addParameter("password","razisami1234")
        .build();
httpclient.execute(request, response -> {
    // do something useful with the response
    return null;
});
