Question

我知道这是一个记录良好的问题，但我无法让它工作...... 请不要发送给我其他主题，我已经检查了它们，我无法得到这个东西，我无法理解为什么。

我使用此代码将数据从Android发送到PHP

    HttpClient httpclient = new DefaultHttpClient();
    HttpResponse response;
    String responseString = null;

    HttpPost httpRequest = new HttpPost(
        "http://example.com/myScript.php");

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("latitude", latLng[0]+""));
    nameValuePairs.add(new BasicNameValuePair("longitude", latLng[1]+""));
    nameValuePairs.add(new BasicNameValuePair("altitude", alt+""));
    try {
        nameValuePairs.add(new BasicNameValuePair("name_comment", URLEncoder.encode(name_comment, "UTF-8").replaceAll("\'", "\\\'")));
    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
    }

    try {
        httpRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        response = httpclient.execute(httpRequest);
        StatusLine statusLine = response.getStatusLine();
        if(statusLine.getStatusCode() == HttpStatus.SC_OK){
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            response.getEntity().writeTo(out);
            out.close();
            responseString = out.toString();
        } else{
            //Closes the connection.
            response.getEntity().getContent().close();
            dataObject.setResponseStatus(statusLine.getStatusCode());
            Log.e(TAG, "Network error: "+statusLine.getReasonPhrase());
            return dataObject;
        }
    } catch (ClientProtocolException e) {
        //TODO Handle problems..
        Log.e(TAG, "ClientProtocolException: "+e.getMessage());
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        Log.e(TAG, "UnsupportedEncodingException: "+e.getMessage());
        e.printStackTrace();
    } catch (IOException e) {
        //TODO Handle problems..
        Log.e(TAG, "IOException: "+e.getMessage());
    }

然后PHP使用此代码将数据插入到MySql表中

$keys = array_keys($_POST);

$con=mysqli_connect("example.com","user","password","database");
mysql_set_charset('utf8mb4');
mysql_query( "SET NAMES 'utf8mb4'");

$query = "INSERT INTO poi ";

$names = "(";
$values = "(";

for ($i = 0; $i < count($_POST)-1; $i++) {
    $names .= $keys[$i].", ";
    $values .= $_POST[$keys[$i]].", ";
}
$names .= $keys[count($_POST)-1].") ";
$values .= "'".addslashes(urldecode($_POST[$keys[count($_POST)-1]]))."') ";

$query .= $names."VALUES ".$values;

$result = mysqli_query($con,$query);

mysqli_close($con);

数据库中的TEXT编码设置为'utf8mb4_general_ci'，我也尝试了不同的编码方法，但是当我尝试插入这个字符串时，我总是得到这个文字“Ã¨unpo'”：“èunpo po” “

我还返回$query字符串以通过LogCat进行双重检查，查询为：

INSERT INTO database (latitude, longitude, altitude, name_comment) VALUES (44.10630374283182, 9.869672544300556, 32.9398994, 'è un po\' '

请不要发送给我其他主题，我已经检查了它们，我无法得到这个东西，我无法理解为什么。

将数据从Android发送到PHP并在带有重音的MySql中插入
