在截击请求中的UTF-8编码

In my Android app I am loading json data with a Volley JsonArrayRequest. The data were created by myself and I saved them with Sublime with UTF-8 encoding. When I get the Response and fill my ListView, the texts are not displayed correctly (umlauts). This is what my Request looks like:

在我的Android应用程序中，我正在用一个Volley JsonArrayRequest加载json数据。数据是我自己创建的，我用UTF-8编码崇高地保存了它们。当我收到回复并填满我的列表视图时，文本不会被正确显示(umlauts)。这就是我的要求:

JsonArrayRequest request = new JsonArrayRequest(targetUrl,
                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(final JSONArray response) {
                        try {
                            fillList(response);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                },
                new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });
        requestQueue.add(request);

When I load the exact same data with this method, all texts are displayed correctly:

当我用这种方法加载完全相同的数据时，所有文本都显示正确:

final StringBuilder builder = new StringBuilder();
        final HttpClient client = new DefaultHttpClient();
        final HttpGet httpGet = new HttpGet(request);
        try {
            final HttpResponse response = client.execute(httpGet);
            final StatusLine statusLine = response.getStatusLine();
            int statusCode = statusLine.getStatusCode();
            if (statusCode == 200) {
                final HttpEntity entity = response.getEntity();
                final InputStream content = entity.getContent();
                final BufferedReader reader = new BufferedReader(new InputStreamReader(content));
                String line;
                while ((line = reader.readLine()) != null) {
                    builder.append(line);
                }
            } else {

            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

So to me it seems like there is no problem with the encoding of my json file. How can I fix this encoding problem in Volley?

对我来说，json文件的编码似乎没有问题。如何在截击中解决这个编码问题?

If you know that absolutely all of the files you are requesting will be in the UTF-8 format, which it sounds like you do, then you might consider forcing your Volley request to return UTF-8 formatted strings. You could accomplish this by subclassing the standard JSON request. Something like this:

如果您知道您所请求的所有文件都是UTF-8格式，这听起来就像您所做的那样，那么您可以考虑强制您的截击请求返回UTF-8格式的字符串。您可以通过子类化标准JSON请求来实现这一点。是这样的:

public class Utf8JsonRequest extends JsonRequest<JSONObject> {
    ...
    @Override
    protected Response<JSONObject> parseNetworkResponse (NetworkResponse response) {
        try {
            String utf8String = new String(response.data, "UTF-8");
            return Response.success(new JSONObject(utf8String), HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            // log error
            return Response.error(new ParseError(e));
        } catch (JSONException e) {
            // log error
            return Response.error(new ParseError(e));
        }
    }
}

I have same problem like this and i solve it using UTF-8 charset.

我有同样的问题，我用UTF-8字符集来解决。

String str = "";
try {
     str = new String(strFromService.getBytes("ISO-8859-1"), "UTF-8");
} catch (UnsupportedEncodingException e) {

 e.printStackTrace();
}

String decodedStr = Html.fromHtml(str).toString();

I hope this will work for you

我希望这对你有用

#3

donot use try{} catch in the onResponse block, that is giving some problem in my code , rather than that you can implement like this .

不要在onResponse块中使用try{} catch，这会给我的代码带来一些问题，而不是像这样实现。

@Override 
onResponse(String s) {

s= fixEncoding(s);
Toast.makeToast(this,s,Toast.LENGTH_LONG).show();

}

and i think you will get the required result

我想你会得到要求的结果

 public static String fixEncoding(String response) {
            try {
                byte[] u = response.toString().getBytes(
                        "ISO-8859-1");
                response = new String(u, "UTF-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
                return null;
            }
            return response;
        }

This is worked as a charm for me,, I just created a static method from @Muhammad Naeem's answer,, Thanks Muhammed..

这对我来说是一种魅力，我刚从@Muhammad Naeem的回答中创建了一个静态方法，谢谢。

public static String fixEncodingUnicode(String response) {
    String str = "";
    try {
        str = new String(response.getBytes("ISO-8859-1"), "UTF-8");
    } catch (UnsupportedEncodingException e) {

        e.printStackTrace();
    }

    String decodedStr = Html.fromHtml(str).toString();
    return  decodedStr;
}

#5

another approach: you can encode your whole response by this line of code.

另一种方法:您可以用这一行代码对整个响应进行编码。

newStr = URLDecoder.decode(URLEncoder.encode(oldStr, "iso8859-1"),"UTF-8");

I have encoded whole response string into UTF-8 as I know volley default encode method is iso8859-1

我已经将整个响应字符串编码为UTF-8，因为我知道volley默认编码方法是iso8859-1。

#6

Add this line of code inside response of volley :

在回击中加入这一行代码:

 public void onResponse(String response) 
    {

     if (response != null) 
      {
        response=new String(response.getBytes("ISO-8859-1"), "UTF-8");
      }
   }

#7

To specify in server part set utf-8 in content type like "text/html;charset=utf-8"

在服务器部分设置utf-8中以“text/html;charset=utf-8”等内容类型指定

I had the same problem earlier two days ago and i have tried every thing my friends just said and it`s the same problem and i tried so meany things .. my file is written in php and using volley to get the data as json i followed these steps to solve the problem ..

两天前我遇到了同样的问题，我试过了我朋友说的每句话，都是一样的问题，我试过了。我的文件是用php编写的，使用volley获取json格式的数据。

1. before executing the query in your database write this query

   在执行数据库中的查询之前，请编写此查询

   mysqli_query($this->connection,"set_NAMES_utf8");

   mysqli_query($ this - >连接,“set_NAMES_utf8”);

2. use this header in your file if it`s php

   如果是php，请在文件中使用这个头

   header('Content-Type: application/json ; charset=utf-8 ');

   标题(“application / json内容类型:;charset = utf - 8 ');

3. while you are echoing the json according to php there is a solve for this problem use this special charachter in json_encode($json,JSON_UNESCAPED_UNICODE)

   当您根据php对json进行响应时，可以使用json_encode($json,JSON_UNESCAPED_UNICODE)中的这个特殊charachter来解决这个问题
