问题描述
|
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协议时,一切工作正常:
<?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,它运行1-2天后会失败。回收asp.net进程后,它可以正常工作。它可以工作1-2天,然后失败:
Exception information:
Exception type: InvalidOperationException
Exception message: Request format is unrecognized for URL unexpectedly ending in \'/Convert\'.
Request information:
Request URL: https://xxx/xxx/converter.asmx/Convert

为什么要等待2天才能失败?我该怎么做才能防止失败?
该服务器以HTTPS模式运行与该事实有关吗?
解决方法
什么是点网框架? IIS 6或7?
您是否尝试过在协议部分添加ѭ3。似乎有些人已经解决了该问题。 (但不是全部)

还要检查您将站点部署到哪里。是在Web服务器的根级别还是虚拟文件夹中。有时可能是从父级站点或machine.config文件继承一些配置值。
否则,可能与代码中的某些内存泄漏有关。您如何处理已加载的XML。
另外,我假设您正在解析有效的XML。

, 似乎默认情况下该协议是禁用的。 Stackoverflow中已经回答了类似的问题。检查此链接和相关问题
