如何在android中获取utf-8API响应内容

编辑： 多亏了一些awnsers，我将我的方法编辑成这样，但仍然并没有摆脱？马克

 public String makeHttpGetRequestUtf8(String urlStr) throws IOException {
    String result = "";
    try {
        URL url = new URL(urlStr);
        //BufferedReader brIn = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8")); //<--- Tried this first but didn't help.
        BufferedReader brIn = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8)); //<-- This also didn't help :(

        String line = "";
        while ((line = brIn.readLine()) != null)
            result += line;
    }catch (Exception e){
        Log.e("HTT_GET", "Failed to make httpGetRequestUtf8: " + e);
    }
    String afterDecode = URLDecoder.decode(result, "UTF-8");
    return afterDecode;
}

这将返回带有问号的响应

httpGet 2：

 public String makeHttpGetRequestUtf8(String urlStr) throws IOException {
    String result = "";
    try {
        URL url = new URL(urlStr);
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        InputStream isr = con.getInputStream();

        // convert inputstream to string
        if(isr != null)
            result = convertInputStreamToString(isr);
        else
            result = "Could not make httpGetResul success";

    } catch (Exception e) {
        Log.d("InputStream", e.getLocalizedMessage());
    }
    return result;
}

// convert inputstream to String
private static String convertInputStreamToString(InputStream inputStream) throws IOException{
    BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
    String line = "";
    String result = "";
    while((line = bufferedReader.readLine()) != null)
        result += line;

    inputStream.close();
    return result;

}

同样的故事

我认为我在这些编码问题上犯了一些原则性错误。

感谢您的提示。

要转换InputStream，您可以使用以下内容：

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

或者在Java7中，您可以这样做

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

编辑：

您还可以尝试使用InputStreamReader（它将检测HTTP响应的编码）：

如果不起作用，您可能需要在响应中设置编码，然后：

response.setContentType("text/html");    
response.setCharacterEncoding("UTF-8");

您可以尝试

UrlDecode（）

。将UrlDecode添加到问题编辑中，仍然没有更改。谢谢，我两次都尝试了，但都没有成功。仍然有错误。我还将我更改的新方法添加到问题编辑中。我没有收到错误，但结果字符串中有问号。示例：“�阿尔德莱克特里特��d koos Infotehnologia kaabeldusega teostatud…“这些是什么”？字符应该是什么？以下是显示为的字符？标记：“ä”、“õ”、“ö”、“ü”

String responseBody = EntityUtils.toString(entity);

response.setContentType("text/html");    
response.setCharacterEncoding("UTF-8");
