如何使用Apache HttpClient在Post请求中编码俄语文本？

Question

有以下Java代码:

    public static void register(UserInfo info) throws ClientProtocolException, IOException, JSONException, RegistrationException {
        List<NameValuePair> params=new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("name", info.getName()));
        params.add(new BasicNameValuePair("email", info.getEmail()));
        params.add(new BasicNameValuePair("pass", info.getPassword()));
        params.add(new BasicNameValuePair("genus", String.valueOf(info.getGenus())));
        String response=doPostRequest(params, REGISTRATION_URL);
    }

private static String doPostRequest(List<NameValuePair> params, String url) throws ClientProtocolException, IOException {
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);

    httppost.setEntity(new UrlEncodedFormEntity(params));
    HttpResponse response = httpclient.execute(httppost); 

    return getContentFromInputStream(response.getEntity().getContent());
} 

private static String getContentFromInputStream(InputStream is) throws IOException {
    String line;
    StringBuilder sb=new StringBuilder();
    BufferedReader reader=new BufferedReader(new InputStreamReader(is));
    while((line=reader.readLine())!=null) {
        sb.append(line);
    }
    reader.close();
    return sb.toString();
}

如您所见,我发送POST请求并获得响应.但在注册方法我使用俄语名称(西里尔文),并有"????? ???" 在我的服务器上.我该如何解决？我如何编码俄文？

Answer 1

您需要将请求编码设置为UTF-8.

The request or response body can be any encoding, but by default is ISO-8859-1. The encoding may be specified in the Content-Type header, for example:
Content-Type: text/html; charset=UTF-8

如何实现这一目标的一个例子:

HttpClient httpclient = new HttpClient();
httpclient.getParams().setParameter("http.protocol.version", HttpVersion.HTTP_1_1);
httpclient.getParams().setParameter("http.protocol.content-charset", "UTF-8");

另外,我看到你的使用UrlEncodedFormEntity.您应该将编码添加到构造函数中,如下所示:

new UrlEncodedFormEntity(nameValuePairs,"UTF-8");

也许您读或写的答案是错误的？

确保在写入请求和读取请求以及post http headers中使用相同的编码。

要定义读取数据的编码，请使用InputStreamReader(InputStream, Charset)构造函数。
