如何通過UTF-8中的http發送字符串

Question

我嘗試發送字符串「Приветмир！」

String link = POST_URL; 
HttpClient httpclient = new DefaultHttpClient(); 
HttpPost httppost = new HttpPost(link); 
String xml ="Привет мир"; 
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
nameValuePairs.add(new BasicNameValuePair("file", xml)); 
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
HttpResponse response = httpclient.execute(httppost); 

而且通過PHP腳本保存：

if(!empty($_REQUEST['file'])){ 
$fp = fopen("C:\\windows\\temp\\1.xml", "w"); 
$mytext =$_POST["file"]; 
$test = fwrite($fp, $mytext); 
fclose($fp); 

，但我得到?????? ?????在我的Web服務器上，我嘗試使用utf編碼重新打開文件，但它沒有幫助。我該如何解決它。

Answer 1

StringEntity的字符集轉換爲UTF-8。這些線路將這樣的伎倆：

httpPost.setEntity(new StringEntity(body, HTTP.UTF_8)); 

Answer 2

這爲我工作：

HttpPost httpPost = new HttpPost("http://someurl.com"); 
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair, HTTP.UTF_8));
