Question

编辑：感谢一些使用过的芒果我编辑了我的方法，但仍然没有得到它的消除？标记。

 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;
}

在android中我尝试了两个httpGet方法来获取api的响应。两者都返回带有问号的内容，这意味着没有utf-8支持。

浏览器上的相同api调用返回UTF-8支持的文本。答案是在json。

httpGet 1：

public String makeHttpGetRequest(String urlStr) throws IOException {
    URL url = new URL(urlStr);
    HttpURLConnection con = (HttpURLConnection) url.openConnection();
    InputStreamReader isr = new InputStreamReader(con.getInputStream());
    String response = readUntilEndOfStream(isr);
    isr.close();
    return response;
}

private String readUntilEndOfStream(InputStreamReader isr) throws IOException {
    StringBuffer data = new StringBuffer();
    int character = isr.read();
    while (character != END_OF_STREAM) {
        data.append((char) character);
        character = isr.read();
    }
    return data.toString();
}

这会返回带有问号的回复。

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。

我认为我在编码问题上存在一些原则性错误。谢谢你的提示。

Answer 1

要转换InputStream，您可以使用以下内容：

$insert_query

或在java 7中你可以做到

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

编辑：

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

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

如果它不起作用，可能需要在响应之前设置编码：

String responseBody = EntityUtils.toString(entity);

如何在android中获取utf-8 api响应内容
