java - HttpPost 查看帖子参数

Question

我希望能够使用参数查看完整的 HttpClient/HttpPost URI。我不确定如何将其输出到我的控制台。

HttpClient httpclient = HttpClients.createDefault();
HttpPost httppost = new HttpPost(url);
httppost.setHeader("ContentType","application/x-www-form-urlencoded");
httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
System.out.println(httppost.getURI());

打印getURI仅输出baseURI而不输出参数。

有人可以帮我解决我所缺少的东西吗？

实体有一种方法可以将自身序列化为输出流writeTo()，因此您可以创建一个输出流并将实体转储到那里。这不是整个请求，只是暴露编码参数的 UrlEncodedFormEntity:

ByteArrayOutputStream outs = new ByteArrayOutputStream();
httppost.getEntity().writeTo(outs);
System.out.println(outs.toString("UTF-8"));
outs.close();

结果是这样的一行:

foul=play&foo=bar&baz=bam
