Question

我正在尝试使用PHP传递数据（来自服务器），数据由中文字符组成。我试图使用我设法检索数据的JSON解析器解析数据，但数据（中文）显示为???。有人可以告诉我出了什么问题吗？

以下是我的解析器：

// function get json from url
    // by making HTTP POST or GET method
    public JSONObject makeHttpRequest(String url, String method,
            List<NameValuePair> params) {

        // Making HTTP request
        try {

            // check for request method
            if(method == "POST"){
                // request method is POST
                // defaultHttpClient
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(url);
                httpPost.setEntity(new UrlEncodedFormEntity(params));

                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();
                is = httpEntity.getContent();

            }else if(method == "GET"){
                // request method is GET
                DefaultHttpClient httpClient = new DefaultHttpClient();
                String paramString = URLEncodedUtils.format(params, "utf-8");
                url += "?" + paramString;
                HttpGet httpGet = new HttpGet(url);

                HttpResponse httpResponse = httpClient.execute(httpGet);
                HttpEntity httpEntity = httpResponse.getEntity();
                is = httpEntity.getContent();
            }           


        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        // try parse the string to a JSON object
        try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        // return JSON String
        return jObj;

    }

在我的logcat上看到。

Answer 1

我的db已经默认为utf8，遇到同样的问题。

添加了常用的元标记＆＃34;＆＃34;后，问题仍然存在。

然后我创建了一个专用的connection.php以确保与mysql的所有通信都是charset utf8，注意mysqli_set_charset中的utf8中没有＆＃34; - ＆＃34; （$ bd，＆＃39; utf8＆＃39;）！

<强> Connection.php

<?php
    $mysql_hostname = "localhost";
    $mysql_user = "username";
    $mysql_password = "password";
    $mysql_database = "dbname";
    $prefix = "";
    $bd = mysqli_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
    mysqli_select_db($bd, $mysql_database) or die("Could not select database");
    if(!mysqli_set_charset($bd, 'utf8'))  {
        exit() ;
    }

?>

以下是发送检索数据的示例。

<?php

    //Include database connection details
    require_once('connection.php');

        enter code here

    //Create query
    $qry = "SELECT * FROM subject";
    $result = mysqli_query($bd, $qry);
    //  other stuff
?>

Answer 2

解决。您需要在utf8中对POST进行编码。

 if(method == "POST"){
            // request method is POST
            // defaultHttpClient

            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params,"utf-8")); <------ utf8

Answer 3

public static String test(){
String testResult= "";
try {
    HttpGet get = new HttpGet("http://xxxxx");//edit url removed.
    DefaultHttpClient httpclient = new DefaultHttpClient();
    HttpResponse response = httpclient.execute(get);
    String result = EntityUtils.toString(response.getEntity());
    JSONObject obj = new JSONObject(result);
    if(!obj.isNull("title")){
        testResult= obj.getString("title");
        Log.d("Test","Test1:"+ testResult);
    }
} catch (JSONException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
return testResult;//

}

从这段代码中获取帮助..这肯定会对你有所帮助.. 享受

您不提供检索数据的代码段。这是我猜测源字符集是UTF-8，相应地替换你的源编码。

InputStreamReader isr = new InputStreamReader(new ByteArrayInputStream(str.getBytes(Charset.forName("UTF-8"))), Charset.forName("UTF-8"));

str是你的json字符串。

更新：似乎您使用iso-8859-1进行检索，因此请尝试将代码更新为UTF-8。

注意：JSON文本的字符编码始终是Unicode。 UTF-8是唯一有意义的编码，但也允许UTF-16和UTF-32（source）。
