远程服务器返回意外响应:(400)错误请求

Question

调用我的WCF服务方法时,我没有收到任何错误.

这个名为SaveTemplate()的特殊方法接受byte []的输入.

我正在使用大小为byte [806803]的文件测试此方法,但以错误结束:

WCF - 远程服务器返回意外响应:(400)错误请求.*

我已经查看了我在Google上找到的几个搜索结果,并根据这些在app.config中进行了一些更改,但仍然收到错误:-(

这是我的WCF服务库的App.Config文件:

<?xml version="1.0" encoding="utf-8" ?>

  <system.web>
    <compilation debug="true" />

由于您似乎是在IIS中的ASP.NET内部托管,因此除了WCF的各种设置之外,还需要确保ASP.NET允许的请求长度.对于ASP.NET你正在寻找的设置maxRequestLength上的httpRuntime元素.此设置的默认值仅为4MB,因此可以解释您遇到问题的原因.

对于512MB maxLength,这看起来有点像这样:

<system.web>
    <httpRuntime maxRequestLength="524288" />

    <!-- rest of your config here -->
</system.web>
