处理多部分/表单数据请求失败。读取超时

java upload tomcat applet
2022-09-01 22:44:34

Stack Overflow上的其他问题已经解决了这个问题，但提供的答案都没有帮助我解决这个问题。

我正在尝试使用Apache HTTP Commons从小程序上传10 kB到16 MB之间的任何文件。在我当地的环境中，一切都很好。

我只在我的生产服务器（Tomcat 6.0，https://www.dailyrazor.com/）上收到以下异常，无论文件大小如何：

除了这个上传问题，我的小程序工作正常。

这是服务器的配置，如我的生产服务器文件中所述：server.xml

<!-- 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（2.01 Mbps下降和0.42 Mbps上升），所以这个例外让我感到困惑。我已经设置为3000000，但我仍然遇到异常。我是否应该设置为 -1 以使其无限制？connectionTimeOutconnectionTimeOut

文件权限设置为从中上传的目录，并且我正在使用JDK版本7在浏览器中运行小程序。777

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，我在控制台中得到这个：

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

以下是执行上载的代码：

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();
    }

当我按下小程序 GUI 上的上传按钮时，它会调用上述方法，同时 GUI 冻结。10 到 50 秒后，服务器抛出 .servlet 会通知小程序有关异常的信息，但小程序会挂起四到五分钟，然后再通知用户异常。FileUploadException

如果服务器端出现问题，为什么会有这么多延迟？


答案 1

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

基本上在我的服务器中.xml我将其设置为：

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

答案 2

从问题中看不出您正在使用什么配置（或您已经尝试过什么）运行，但问题几乎在于根据定义，在上传过程中超过了套接字超时。

引发此错误是因为在达到相关超时之前未完全收到文件。这与测试中（在本地网络上）工作的情况一致，但在通过慢得多的互联网运行时（特别是在上传速度方面）时则不然。

看看你的相关定义。您将对 or 属性的值感兴趣（如果设置为 true，则后者）。server.xml<Connector>connectionTimeoutconnectionUploadTimeoutdisableUploadTimeout

在没有更多邪恶问题的证据的情况下，我希望您只需增加连接超时即可解决此问题。
