Android的Java的UTF-8 Htt​​pClient的问题

问题描述

我有一个从网页上抓起一个JSON阵列奇怪的字符编码​​问题。服务器发回这个头：

I am having weird character encoding issues with a JSON array that is grabbed from a web page. The server is sending back this header:

Content-Type的文/ JavaScript的;字符集= UTF-8

Content-Type text/javascript; charset=UTF-8

另外，我可以看看JSON输出Firefox或者任何浏览器和统一code字符显示正常。该反应有时会包含有重音符号和这样的另一种语言的话。但是我得到的那些奇怪的问号时，我拉下来，并把它放到一个字符串中的Java。这是我的code：

Also I can look at the JSON output in Firefox or any browser and Unicode characters display properly. The response will sometimes contain words from another language with accent symbols and such. However I am getting those weird question marks when I pull it down and put it to a string in Java. Here is my code:

HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "utf-8");
params.setBooleanParameter("http.protocol.expect-continue", false);

HttpClient httpclient = new DefaultHttpClient(params);

HttpGet httpget = new HttpGet("http://www.example.com/json_array.php");
HttpResponse response;
    try {
        response = httpclient.execute(httpget);

        if(response.getStatusLine().getStatusCode() == 200){
            // Connection was established. Get the content.

            HttpEntity entity = response.getEntity();
            // If the response does not enclose an entity, there is no need
            // to worry about connection release

            if (entity != null) {
                // A Simple JSON Response Read
                InputStream instream = entity.getContent();
                String jsonText = convertStreamToString(instream);

                Toast.makeText(getApplicationContext(), "Response: "+jsonText, Toast.LENGTH_LONG).show();

            }

        }


    } catch (MalformedURLException e) {
        Toast.makeText(getApplicationContext(), "ERROR: Malformed URL - "+e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (IOException e) {
        Toast.makeText(getApplicationContext(), "ERROR: IO Exception - "+e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (JSONException e) {
        Toast.makeText(getApplicationContext(), "ERROR: JSON - "+e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }

private static String convertStreamToString(InputStream is) {
    /*
     * To convert the InputStream to String we use the BufferedReader.readLine()
     * method. We iterate until the BufferedReader return null which means
     * there's no more data to read. Each line will appended to a StringBuilder
     * and returned as String.
     */
    BufferedReader reader;
    try {
        reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
    } catch (UnsupportedEncodingException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    StringBuilder sb = new StringBuilder();

    String line;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}

正如你所看到的，我指定UTF-8上的InputStreamReader但每次我通过吐司查看返回的JSON文本有奇怪的问号。我想，我需要的的InputStream发送到一个byte []呢？

As you can see, I am specifying UTF-8 on the InputStreamReader but every time I view the returned JSON text via Toast it has strange question marks. I am thinking that I need to send the InputStream to a byte[] instead?

在此先感谢您的帮助。

推荐答案

试试这个：

if (entity != null) {
    // A Simple JSON Response Read
    // InputStream instream = entity.getContent();
    // String jsonText = convertStreamToString(instream);

    String jsonText = EntityUtils.toString(entity, HTTP.UTF_8);

    // ... toast code here
}
