我收到来自 ASP.Net 网站的关于使用 AJAX 提交大文件 2GB 的错误请求。
我的 HTTP 运行时设置
<httpRuntime maxRequestLength="2147483647" executionTimeout="3600"/>
请帮忙。

最佳答案
maxRequestLength 的单位是千字节，而不是字节，所以 2147483647 千字节大约是 2000 GB，这已经很多了。 2GB = 2097152 KB。试试改成2097152
另一方面，maxAllowedContentLength 以字节为单位。
建议将这两个值都放在 web.config 中。
The maxRequestLength indicates the maximum file upload size supported by ASP.NET, the maxAllowedContentLength specifies the maximum length of content in a request supported by IIS. Hence, we need to set both maxRequestLength and maxAllowedContentLength values to upload large files.
<system.web>
<httpRuntime maxRequestLength="2097152" executionTimeout="3600"/>
</system.web>

<requestLimits maxAllowedContentLength="2147483648" />
