Asp.Net Ajax WebService和内部错误500 [英] Asp.Net Ajax WebService and Internal Error 500
问题描述
我可以使用以下URL直接将webservie调用到浏览器,并且返回所需的所有内容:
I can call the webservie directly to the browser with the following URL and it returns be all what I want :
http://localhost:64438/MySearchAutoComplete.asmx/GetCompletionList
当我像这样将其添加到Default.aspx页面的autocompleteexetender中时:
When I add it to an autocompleteexetender into the Default.aspx page like that :
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1"
TargetControlID="TextBox1"
runat="server"
ServiceMethod="GetCompletionList"
ServicePath="http://localhost:64438/MySearchAutoComplete.asmx"
CompletionSetCount="12"
MinimumPrefixLength="1" />
页面加载,我有一个文本框,但是每次在文本框中添加击键时都会出现500错误.我在FireFox FireBug中看到了错误.
The page load, I have a textbox but I have an error 500 every time I add a keystroke in the textbox. I see the error in the FireFox FireBug.
http://localhost:62702/ --->This is the webpage that load fine
->这是错误
有什么主意吗?我已经注意到我需要附加该流程来调试Web服务,我是否也可能对此做错了?
Any idea? I have noticed that I need to attach the process to debug the webservice, I might do something wrong with it too?
如果我进入机器的事件查看器.我可以看到:
If I go to the Event Viewer of my machine. I can see :
Exception information:
Exception type: InvalidOperationException
Exception message: Request format is unrecognized for URL unexpectedly ending in '/GetCompletionList'.
Thread information:
Thread ID: 8
Thread account name: MTL\daok
Is impersonating: False
Stack trace: at System.Web.Services.Protocols.WebServiceHandlerFactory.CoreGetHandler(Type type, HttpContext context, HttpRequest request, HttpResponse response)

at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
我还必须先启动webservice项目,然后再停止并启动webproject才能同时拥有这两个项目.该Web服务仍然有效(我可以直接 http://localhost:64438/MySearchAutoComplete.asmx触发它吗? op = GetCompletionList ),但在网页上我仍然显示错误500.
I also have to start the webservice project first, than I stop it and start the webproject to be able to have both. The webservice still works (I can fire it directly http://localhost:64438/MySearchAutoComplete.asmx?op=GetCompletionList) but on the webpage I still have that Error 500.
添加到webservice项目web.config:
Adding to the webservice project web.config:
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
没有解决问题.
从WebService调用Page_Load()相同的方法效果很好:
Calling in the Page_Load() the same method from the WebService work very well:
string[] stuffs;
stuffs = proxy.GetCompletionList("1", 10);
MyList.DataSource = stuffs;
MyList.DataBind();
但是它不能与AutoCompleteExtender一起使用...
But it's not working with the AutoCompleteExtender...
推荐答案
在网络服务器(即您的本地计算机)上的事件日志中,它应该给出更详细的错误消息.
In the event log on the webserver (i.e. your local machine) it should give a more detailed error message.
将此添加到我认为的web.config
Add this to your web.config I think
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
