具有StringEntity的HttpPost具有特殊字符，如®，看到¿½`而不是®

Question

我需要使用stringentity的特殊字符，如下所示。

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpEntity entity = new StringEntity("test®");
httpPost.setEntity(entity);
httpPost.setHeader("Accept-Encoding", "UTF-8");

HttpResponse response = httpClient.execute(httpPost);
BufferedReader reader =  new BufferedReader(new InputStreamReader((response.getEntity().getContent())));
while ((reader.readLine()) != null) {
    System.out.println (reader.readLine());
}
reader.close();

响应中的输出包含test�而不是test®。

Answer 1

更改为：

    HttpEntity entity = new StringEntity("test®", "UTF-8"); 

Answer 2

我只使用了 ByteArrayEntity ，而不是使用 StringEntity ，

String string = "ã@í";
HttpEntity httpEntity = new ByteArrayEntity(string.getBytes("UTF-8"));
request.addHeader("Content-type", "application/xml;charset=UTF-8");
request.setEntity(httpEntity);
