asp.net - 1-2 天后发生 URL 意外以 '/Convert' 结尾的请求格式无法识别

Question

我正在使用 Microsoft.XMLHTTP 调用来调用 Web 服务:

var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.open("POST", "/xxx/Converter.asmx/Convert", false);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send("conversionFolder=" + escape(conversionFolder));
if (xmlhttp.status == 200) {
  xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
  xmlDoc.async = "false";
  xmlDoc.loadXML(xmlhttp.responseText);
  ... more stuff ...
  return str;
}
else {
  alert(xmlhttp.statusCode + " - " + xmlhttp.statusText);
}

当我记得在本地 web.config 中添加 HttpPost 协议(protocol)时，一切正常:

<?xml version="1.0"?>
<configuration>
  <appSettings/>
  <connectionStrings/>
  <system.web>
    <webServices>
      <protocols>
        <add name="HttpPost"/>
      </protocols>
    </webServices>
    <compilation debug="false"></compilation>
  </system.web>
  <system.codedom>
  </system.codedom>
  <!--
    The system.webServer section is required for running ASP.NET AJAX under Internet
    Information Services 7.0.  It is not necessary for previous version of IIS.
  -->
  <system.webServer>
  </system.webServer>
</configuration>

但是在一台生产服务器上运行 1-2 天后它会失败。在 asp.net 进程被回收后它工作正常。它工作了1-2天，然后失败了:

Exception information:
Exception type: InvalidOperationException
Exception message: Request format is unrecognized for URL unexpectedly ending in '/Convert'.

为什么要等2天才失败？我能做些什么来防止它失败？
这与此服务器以 HTTPS 模式运行有关吗？

什么是点网框架？ IIS 6 还是 7？
您是否尝试添加 <add name="HttpGet"/>在协议(protocol)部分。似乎有些人已经通过该修复解决了这个问题。 (但不是所有人)

还要检查您在哪里部署站点。它是在您的 Web 服务器的根级别还是虚拟文件夹中。有时它可能会从父级站点或 machine.config 文件中继承一些配置值。

否则，它可能与您的代码中的一些内存泄漏有关。你如何处理加载的 XML。
我还假设您正在解析一个有效的 XML。
