php - 从 android 到 JSON 到 mysql Arabic

Question

这是我的 Java 文件。我正在尝试发送无效的阿拉伯文字母而不是我收到的阿拉伯文单词 ????? ？？？？ ??????.

我可以从 MySQL 读取阿拉伯语，但无法将阿拉伯语添加到 MySQL。

public class NewSecret extends Activity {

// Progress Dialog
private ProgressDialog pDialog;

JSONParser jsonParser = new JSONParser();
EditText inputName;
EditText inputDesc;

// url to create new product
private static String url_create_product = "http://laylakaylif.com/android/add_secrets.php";

// JSON Node names
private static final String TAG_SUCCESS = "success";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // fullScreen
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.add);

    // Edit Text
    inputName = (EditText) findViewById(R.id.inputName);
    inputDesc = (EditText) findViewById(R.id.inputDesc);

    LinearLayout ll = (LinearLayout) findViewById(R.id.Lina);

    AdView ad2 = new AdView(NewSecret.this, AdSize.SMART_BANNER,
            "a150b0de6e44a18");
    ll.addView(ad2);
    ad2.loadAd(new AdRequest());

    // Create button
    Button btnCreateProduct = (Button) findViewById(R.id.btnCreateProduct);

    if (inputName.getText().toString().length() <= 0)
        inputName.setError("الرجاء اضافة عنوان!");

    if (inputDesc.getText().toString().length() <= 10)
        inputDesc.setError("الرجاء اضافة نص السر ..");

    // button click event
    btnCreateProduct.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            // creating new product in background thread
            new CreateNewProduct().execute();
        }
    });
}

/**
 * Background Async Task to Create new product
 * */
class CreateNewProduct extends AsyncTask<String, String, String> {

    /**
     * Before starting background thread Show Progress Dialog
     * */
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(NewSecret.this);
        pDialog.setMessage("إضافة سر جديد ...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    /**
     * Creating product
     * */
    protected String doInBackground(String... args) {
        String title = inputName.getText().toString();
        String description = inputDesc.getText().toString();

        String htmltitle;
        String deshtml;

        htmltitle = TextUtils.htmlEncode(title);
        deshtml = TextUtils.htmlEncode(description);

        // Building Parameters
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("title", htmltitle));
        params.add(new BasicNameValuePair("description", deshtml));

        // getting JSON Object
        // Note that create product url accepts POST method
        JSONObject json = jsonParser.makeHttpRequest(url_create_product,
                "POST", params);

        // check log cat fro response
        Log.d("Create Response", json.toString());

        // check for success tag
        try {
            int success = json.getInt(TAG_SUCCESS);

            if (success == 1) {
                // successfully created product
                Intent i = new Intent(getApplicationContext(),
                        AllSecrets.class);
                startActivity(i);

                // closing this screen
                finish();
            } else {
                // failed to create product
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

        return null;
    }

    /**
     * After completing background task Dismiss the progress dialog
     * **/
    protected void onPostExecute(String file_url) {
        // dismiss the dialog once done
        pDialog.dismiss();
    }

}
}

这是我的 PHP JSON 文件:

 <?php
 header("Content-Type:application/json;charset=utf-8"); //global encoding since this is the config file -- for Arabic support
/*

 * All product details are read from HTTP Post Request
 */

// array for JSON response
$response = array();

// check for required fields
/*if (isset($_POST['title']) && isset($_POST['description'])) {

    $title = json_encode($_POST['title'], JSON_UNESCAPED_UNICODE);
    $description = json_encode($_POST['description'], JSON_UNESCAPED_UNICODE);
*/

if (isset($_REQUEST['title']) && isset($_REQUEST['description'])) {
    echo $_REQUEST['title'].'<br/>';
/*
    $title = json_decode($__REQUEST['title']);
    $description = json_decode($__REQUEST['description']);
*/

    $title = $_REQUEST['title'];
    $description = $_REQUEST['description'];

    // include db connect class
    require_once 'db_connect.php';

    // connecting to db
    $db = new DB_CONNECT();

    //setting the connection charset
     mysql_set_charset('utf8',$db);
     mysql_query("SET NAMES 'utf8'");
     mysql_query("SET CHARACTER_SET utf8;");


    // mysql inserting a new row
    mysql_query("SET NAMES 'UTF8'");
    $result = mysql_query("INSERT INTO secrets(title ,  description) VALUES('$title', '$description')");

    // check if row inserted or not
    if ($result) {
        // successfully inserted into database
        $response["success"] = 1;
        $response["message"] = "Secret successfully added.";

        // echoing JSON response
        echo json_encode($response);
    } else {
        // failed to insert row
        $response["success"] = 0;
        $response["message"] = "Oops! An error occurred.";

        // echoing JSON response
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";

    // echoing JSON response
    echo json_encode($response);

Answer 1

JSONObject json = jsonParser.makeHttpRequest(url_create_product, "POST", params);

我不知道你用的是什么 JSONParser。它不是标准平台的一部分；网络上散布着数十种不同的类，其中许多都包含这样一行:

httpPost.setEntity(new UrlEncodedFormEntity(params));

这是一个问题，因为 default UrlEncodedFormEntity 的编码是 ISO-8859-1 而不是 UTF-8。如果你想通过UTF-8，include它作为参数:

httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

如果这不是问题，建议发布 JSONParser 代码。
