Android 到 php 发送 UTF8 编码文本,不适用于西里尔文或阿拉伯字符


Android to php send UTF8 encode text, not working with cyrillic or arabic characteres

我需要将字符串从Android发送到php Web服务(用户在EditText中输入(。运行正常,带有标准字符和一些特殊字符(如重音符号、ñ 等(,但是当我发送西里尔或阿拉伯语字符时,Web 服务无法识别,并替换为其他字符(如 â±ÐÒ(。这是我的安卓代码:

// Post the data:
public class Sincronizar extends AsyncTask<JSONObject, JSONObject, JSONObject> {
    String resFromServer=null;
    private String url = "http://.../send.php"; //The url of the web service
    @Override
    protected JSONObject doInBackground(JSONObject... data) {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);
        JSONObject jsonResponse = null;
        try {
            JSONObject jsonPlace = new JSONObject();
            jsonPlace.put("pais", ((EditText)findViewById(R.id.etTexto)).getText().toString());
            JSONArray postjson=new JSONArray();
            postjson.put(jsonPlace);
            // Post the data:
            httppost.setHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
            httppost.setHeader("json",jsonPlace.toString());
            httppost.getParams().setParameter("jsonpost",postjson);
            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            if (response.getEntity()!=null) {
                resFromServer = org.apache.http.util.EntityUtils.toString(response.getEntity());
                jsonResponse=new JSONObject(resFromServer);
            } 
        } catch (Exception e) { 
            Log.e("Sincronizar","doIn:"+resFromServer);
        }
        return jsonResponse;
    }
    @Override
    protected void onPostExecute(JSONObject jsonResponse) {
        try{
            if (jsonResponse!=null) {
                String pais = jsonResponse.getString("pais");
                String respuesta = String.format("PAIS: %s",pais);
                Log.e("Sincronizar",""+respuesta);
                ((TextView)findViewById(R.id.textView1)).setText(respuesta);
            }
        }catch (Exception e) {
            Log.e("Sincronizar","onPostExecute: "+e.getMessage());
        }
        super.onPostExecute(jsonResponse);
    }
}

这是php Web服务:

<?php
header('Content-Type: text/html; charset=utf-8');
try {
    if (isset($_SERVER['HTTP_JSON'])) {
    $json = $_SERVER['HTTP_JSON'];
    $cadena = utf8_encode($json);
    $data = json_decode($cadena,true);
    $json_error= json_last_error();
    $pais = $data["pais"];  
} else {
    $pais="No received";
}
}catch(Exception $e) {
    $pais="Exception: ".$e->getMessage();
}
$output=array('pais'=>$pais);
print(utf8_encode(json_encode($output)));
?>

在Web服务中,我还尝试将收到的字符串插入Mysql DB。正常的和一些特殊的字符,如 Ñ、á(重音(等,被接收 e 插入正常。但是对于阿拉伯语或西里尔字符,我会收到这种字符串:"±±","±Ã'À">

我认为

问题是编码,但我发送和接收 UTF8(我认为(知道吗?谢谢!

在 php 运行服务器上的 Sql 操作之前

$mysqli->set_charset("utf8")

(或等效的,我使用了mysqli(这解决了我的问题

mysqli_set_charset($con,'utf8');
mysqli_query($con, "insert into table (name, lastname) values ('Ñishá', 'Akopov')");

您可以编写 select 语句并在 utf8 中检索行

希望这会有所帮助

试试这个函数,这可能会对你有所帮助

function parseUtf8ToIso88591($string){
     if(!is_null($string)){
            $iso88591_1 = utf8_decode($string);
            $iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $string);
            $string = mb_convert_encoding($string, 'ISO-8859-1', 'UTF-8');  
            return "";
     }
     return $string;
}
