如何将url中的阿拉伯语文本作为参数从android app发送到php webservice

问题描述：

I want to add search function in my android app, but the problem is when i add arabic parameter to url e.g("example.com?q=بلد") it gives null result. although if i add text manually in browser to url it works fine.

        InputStream inputStream = null;
        String contentAsString = null;
        try {
            URL url = new URL("example.com?q=بلد");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.connect();
            inputStream = conn.getInputStream();
            contentAsString = readIt(inputStream);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

PHP code

    header('Content-Type: text/html; charset=utf-8');

    mysql_select_db($this->get_databaseName(), $this->con);
    mysql_query("SET NAMES 'utf8'");
    mysql_query('SET CHARACTER SET utf8');

    $query="Select * from tbl_posts where post_title=".$_GET['q']";

Data base table field encoding method is utf8_general_ci

In simple words i want to add some arabic text as parameter in url, through which i can query database using php web service.

我想在我的Android应用程序中添加搜索功能，但问题是当我向网址添加阿拉伯语参数时（例如） “example.com?q=بلد”）它给出了null结果。虽然如果我在浏览器中手动添加文本到url它工作正常。 p>

  InputStream inputStream = null; 
 String contentAsString = null; 
尝试{
 URL url = new  URL（“example.com?q=بلد”）; 
 HttpURLConnection conn =（HttpURLConnection）url.openConnection（）; 
 conn.connect（）; 
 inputStream = conn.getInputStream（）; 
 contentAsString = readIt  （inputStream）; 
} catch（Exception e）{
 e.printStackTrace（）; 
} finally {
 if（inputStream！= null）{
 try {
 inputStream.close（）; 
  } catch（IOException e）{
 e.printStackTrace（）; 
} 
} 
}

 mysql_query（'SET  CHARACTER SET utf8'）; 
 
 $ query =“select * from tbl_posts where post_title =”。$ _ GET ['q']“;

简单来说，我想在url中添加一些阿拉伯语文本作为参数，通过它我可以使用php web服务查询数据库。 p>

While sending such kind of special characters to server you need to encode such input with the help of URLEncoder.encode(your_input, "utf-8") and while receiving such kind of data first of all you need to decode it with the help of URLDecoder.decode(your_data, "utf-8")

答

I think u have to url encode your query before you send it. like this:

String query = URLEncoder.encode("بلد", "utf-8");

URL url = new URL("example.com?q=" + query);

I have solved the problem with the help of Zesshan khan answer

Final code is

Adnroid

   String str=بلد;
   str=URLEncoder.encode( str, "utf-8")  
   URL url = new URL("example.com?q= "+str);

PHP

  header('Content-Type: text/html; charset=utf-8');

 mysql_select_db($this->get_databaseName(), $this->con);

 mysql_query("SET NAMES 'utf8'");

. .

$result=uldecoder($_GET["data"]);

. .

$query="Select * from tbl_posts where post_title=".$result.";
