Question

我有一个3rd party api，它给了我一些json响应

{
"name": "บรีส",
"company": "Таиланд",
}

在上述Json回复中，我有一些泰语字符，当我直接访问api时，我会得到正确的泰语字符，但是当我从RestClient调用它时，我会得到该字符为????

{
"name":"????????????",
"company":"??????????????"
}

这是我的RestClient代码

private void executeRequest(HttpUriRequest request,    String url) throws CommonException, IOException{
    //logger.debug(CLASS_NAME+" executeRequest : Entry :: url ->"+url + " Request: "+ postData );
    RequestConfig requestConfig = RequestConfig.custom()
               .setConnectTimeout(connectionTimeOut)
               .setConnectionRequestTimeout(soTimeOut)
               .setSocketTimeout(soTimeOut)
               .build();

    CloseableHttpClient client;

        client = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig)
                .useSystemProperties().build();

    HttpContext localContext = new BasicHttpContext();
    CloseableHttpResponse httpResponse = null  ;
    InputStream instream = null;
    try {
        httpResponse = client.execute(request, localContext);
        responseCode = httpResponse.getStatusLine().getStatusCode();
        message = httpResponse.getStatusLine().getReasonPhrase();
        HttpEntity entity = httpResponse.getEntity();
        if (entity != null) {
            instream = entity.getContent(); 
            response = convertStreamToString(instream);
        }

    } catch (ClientProtocolException e) {
        //logger.debug(CLASS_NAME+" :: executeRequest : ClientProtocolException :: url ->"+url+ " responseCode -> " +  responseCode + "message -> " + message  + " Service Execution Rime: "+lSvcExecTime+"\n  Request -> "+postData + "  Exception : "+ e.getMessage() );
        throw e; 
    }catch (SocketException e) {
        //logger.debug(CLASS_NAME+" :: executeRequest : SocketException :: url ->"+url+ " responseCode -> " +  responseCode + "message -> " + message  + " Service Execution Rime: "+lSvcExecTime+"\n  Request -> "+postData + "  Exception : "+ e.getMessage() );
        throw e; 

    } finally {
        if(httpResponse!=null){
            httpResponse.close();
        }
        if(null != instream){
            instream.close();
        }
    }
}

private static String convertStreamToString(InputStream is) throws UnsupportedEncodingException {
    ByteArrayOutputStream result = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
        int length;
        try {
            while((length = is.read(buffer)) != -1){
                result.write(buffer,0,length);
            }
        } catch (IOException e) {
            //logger.error(CLASS_NAME+" IOException due to - "+e.getMessage());
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                //logger.error(CLASS_NAME+"IOException inside finally due to - "+e.getMessage());
            }
        }
        log.warning("Response in RestClient ---"+result.toString());
        //return result.toString();
        return new String(result.toString().getBytes(), "UTF-8");
}

此代码可以在我的本地系统中完美运行，但是当我在服务器上运行此代码时，它会给我????。

注意：调用RestClient时，我要添加标题-

        client.AddHeader("Content-Type","application/json; charset=utf-8");

请指导我该怎么做。

谢谢。

更改此表达式

new String(result.toString().getBytes(), "UTF-8")

到

new String(result.toByteArray(), "UTF-8")

首先将result转换为字符串，然后再转换为字节，您将使用JVM的默认字符集转换数据，该默认字符集大概是本地计算机上的UTF-8，而不是服务器上的。 >

一些观察结果：

您应该仔细查看生产环境中JVM的设置：将默认编码设置为所需的值，例如UTF-8，因此使用非UTF-8不会感到惊讶。
您无需读入ByteArrayOutputStream，然后再转换为String：将InputStream包裹在InputStreamReader中（指定字符集），然后BufferedReader：然后您可以直接阅读字符，并将其附加到StringBuilder。

泰语字符已转换为问号
