处理多部分/表单数据请求失败读取超时

编程问答 2022-11-20

问题描述

这对我帮助很大：http : //blog.somepixels.net/en/502-proxy-error- uploading-from-apache-mod_proxy-to- tomcat-7/

基本上在server.xml中，将其设置为：

<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8"
       connectionUploadTimeout="36000000" disableUploadTimeout="false"
       connectionTimeout="60000" redirectPort="8443" />

解决方法

关于Stack Overflow的其他问题已经解决了这个问题，但是提供的答案都没有帮助我解决该问题。

我正在尝试使用Apache HTTP Commons从applet上传10 kB至16 MB之间的文件。在我的本地环境中一切正常。

无论文件大小如何，我仅在生产服务器（Tomcat
6.0，https：//www.dailyrazor.com/）上收到以下异常：

除了此上传问题外，我的applet正常运行。

这是生产服务器server.xml文件中描述的服务器配置：

<!-- Define an AJP 1.3 Connector on port 8009 --> <Connector address="127.0.0.1" port="9609" enableLookups="false" protocol="AJP/1.3" connectionTimeout="30000" maxThreads="50" minSpareThreads="1" maxSpareThreads="3" disableUploadTimeout="true" />

我的互联网连接速度很好（降低了2.01 Mbps，提高了0.42
Mbps），所以这个异常让我感到困惑。我已经设置connectionTimeOut为3000000，但是仍然有例外。我应该设置connectionTimeOut为-1以使其不受限制吗？

文件许可权设置为777我上载目录，并且我使用JDK版本7在浏览器中运行小程序。

Java控制台输出：

Java Plug-in 10.7.2.10
Using JRE version 1.7.0_07-b10 Java HotSpot(TM) Client VM

当上传失败时，我会在控制台中看到：

我知道这可能是我的ISP的问题。 我只是想知道这是否是iSP的问题，为什么我可以顺利使用temviewer和Skype等软件？

以下是执行上传的代码：

public static String uploadUsingApache(URL url,List<File> list,String userId,String accountId,String waveDuration)
            throws Exception {

        // The execution:
        DefaultHttpClient httpclient = new DefaultHttpClient();

        HttpPost method = new HttpPost(url.toString());

        MultipartEntity entity = new MultipartEntity();
        entity.addPart("userId",new StringBody(userId,Charset
                .forName("UTF-8")));
        entity.addPart(IVR_ACCOUNT_KEY,new StringBody(accountId,Charset
                .forName("UTF-8")));
        entity.addPart(IVR_MP3LEN_KEY,new StringBody(waveDuration,Charset
                .forName("UTF-8")));

        // FileBody fileBody = new FileBody(list.get(0));
        // entity.addPart("file",fileBody);

        for (File f : list) {

            byte[] imageBytes = fileToByteArray(f);
            entity.addPart("attachment_field",new InputStreamKnownSizeBody(
                    new ByteArrayInputStream(imageBytes),imageBytes.length,"audio/wav",f.getName()));
            method.setEntity(entity);
        }

        ResponseHandler<String> responseHandler = new BasicResponseHandler();

        // HttpResponse response = httpclient.execute(method,responseHandler);
        String responseText = httpclient.execute(method,responseHandler);

        // error text
        if (responseText.contains("<exception>")) {
            responseText = responseText.replace("<exception>","");
            responseText = responseText.replace("</exception>","");
            throw new Exception(responseText);
        }

        // System.out.println(" Status " +response.getStatusLine());
        List<String> deleteList = Arrays.asList(responseText.split(","));

        StringBuffer sb = new StringBuffer();
        int cnt = 1;
        for (File f : list) {
            if (deleteList.contains(f.getName())) {
                sb.append(f.getName() + (cnt == deleteList.size() ? "" : ","));
                f.delete();
                cnt++;
            }

        }

        if (deleteList.size() > 1) {
            sb.append(" are ");
        } else if (deleteList.size() == 1) {
            sb.append(" is ");
        } else {

        }

        sb.append(" successfully saved.");

        return sb.toString();
    }

当我按小程序的GUI上的上载按钮时，它将调用上述方法，同时GUI冻结。10至50秒后，服务器将抛出FileUploadException。Servlet通知小程序有关异常的信息，但是小程序在通知用户异常之前挂起了四到五分钟。

如果服务器端出现问题，为什么会有这么多延迟？
