java - Genexus Uploadify 不适用于大文件

Question

我有一个用 Genexus 创建的网站，其中包含一个 Uploadify 控件，在本地 Tomcat 服务器上运行，它可以很好地处理小文件，但是当我尝试上传一个更大的文件(> 50 MB)时，它似乎在上传文件，但随后返回到交易屏幕。

我使用 Google Chrome 中包含的开发人员工具进行了测试，我注意到，当我尝试上传大文件时，出现“500 - 内部服务器错误”。单击“网络”选项卡中的相应行会显示以下内容:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.28 logs.

Apache Tomcat/5.5.28

在一些网站上搜索，我发现建议编辑应用程序的 web.xml，在 tomcat-directory/application-directory/WEB-INF/web.xml 的 标记内添加以下标记:

<multipart-config>
    <max-file-size>1073741824</max-file-size>
    <max-request-size>1073741824</max-request-size>
    <file-size-threshold>0</file-size-threshold>
</multipart-config>

然后编辑 tomcat-directory/conf/server.xml 使端口 8080 的连接器标记如下所示:

<Connector port="8080" maxHttpHeaderSize="4096" maxPostSize="1073741824"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="600000" disableUploadTimeout="true" />

然后重新启动 Tomcat，但它给了我同样的错误。我还遗漏了什么吗？

提前致谢!

编辑: 实际上，我的应用程序是一个 Java 应用程序，使用的控件不是真正的“Uploadify”，它具有类“Image”并链接到数据库中的 BLOB 字段。更改交易表单中的字段类型不就是这样吗？

Answer 1

在您的表单中检查 Uploadify 属性“大小限制”。

在 web.config 中检查 maxRequestLength在<system.web>和 requestLimits maxAllowedContentLength在<security> .

例子:

<system.web>
 <httpRuntime requestValidationMode="2.0" executionTimeout="600" maxRequestLength="50000"/>
</system.web>

<system.webServer>
 <security>
  <requestFiltering>
   <hiddenSegments>
    <add segment="PrivateTempStorage" />
    <add segment="private" />
   </hiddenSegments>
   <requestLimits maxAllowedContentLength="50000000"/>
  </requestFiltering>
 </security>
</system.webServer>
