HttpClient httpClient = new DefaultHttpClient();
 HttpPost post = new HttpPost(url);List<NameValuePair> params = new ArrayList<>();
 params.add(new BasicNameValuePair("info", "測試"));

 try {
     UrlEncodedFormEntity uefEntity = new UrlEncodedFormEntity(params, HTTP.UTF_8);post.setEntity(uefEntity);
 } catch 
 
(UnsupportedEncodingException e) {
     Log.e("test", "test");
 }

 HttpResponse response = null;

 try {
     response = httpClient.execute(post);
 } catch (Exception e) {
    ……
 }

 if (response.getStatusLine().getStatusCode() == 200) {
     ……
 }

服務端接收到後顯示為亂碼。

解決方法：

HttpPost post = new HttpPost
 
(url);
post.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
