如何上传大（大于25MB）文件添加到Web服务？ [英] How do I upload large (> 25MB) files to a web service?

问题描述

我有一个Web服务，它需要一个byte []，并将其保存。

I have a web service that takes a byte[] and saves it.

这很好地满足小文件，但一旦我打了一定规模的网络服务将失败并返回请求失败，HTTP状态404：未找到

This works fine for "small" files, but once I hit a certain size the web service fails and returns "The request failed with HTTP status 404: Not Found."

这是我所看到的，这似乎是一个能够限制发布（以prevent拒绝服务攻击）的文件大小的IIS设置。我试图提高该设置，但我无法确定什么设置，并在那里/如何能设置。我使用IIS7和web服务是.NET（ASMX）来实现。

From what I've seen this appears to be an IIS setting that limits the size of a file that can be posted (to prevent Denial of Service attacks). I've tried to increase that setting, but I am having trouble determining what setting and where/how one would set it. I am using IIS7 and the webservice is done in .net (asmx).

在Web服务我已经加入以下（这似乎增加文件的大小是可以接受的，但并不是所有的方法来此设置大小）的web.config文件

In the web.config of the web service I have added the following (which seemed to increase the size of file that can be accepted, but not all the way to this setting size)

  <system.web>
     <httpRuntime executionTimeout="999999" maxRequestLength="2097151" />
     ...
  </system.web>

在哪里（以及如何）提高文件的大小，该Web服务将大大AP preciated任何建议。

Any suggestions on where (and how) to increase the size of file that the web service would be greatly appreciated.

推荐答案

在除的httpRuntime / maxRequestLength的问题中所提到的，它看起来像有可以添加到Web服务的web.config文件中追加项目允许大型文件传输。

In addition to the httpRuntime/maxRequestLength mentioned in the question, it looks like there is an additional item that can be added to the web service's web.config file to permit large file transfers.

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2000000000" />
      </requestFiltering>
    </security>
  </system.webServer>

这似乎使较大的文件，以通过Web服务进行上传。

This appears to enable larger files to be uploaded via web services.
