如何在.asmx服务中调用方法 [英] How do I call methods in an .asmx service

问题描述

我正在尝试在创建新的asmx Web服务时调用由visual studio创建的HelloWorld方法。



我已将* .asmx.cs文件添加到测试站点的App_Code文件夹，将.asmx文件添加到站点根目录。如果我去testserver / Service1.asmx，我会看到列出服务方法的页面。



如果我尝试使用testserver / Service1.asmx / HelloWorld，我会收到错误消息。如何运行服务或调用HelloWorld方法。



我花了两天半的时间用谷歌搜索，阅读和观看视频，试图找出我需要做的事情或我做错了什么。

I am trying to call the HelloWorld method that is created by visual studio when you create a new asmx web service.

I have added the *.asmx.cs file to the App_Code folder of the test site and the .asmx file to the sites root. If I go to testserver/Service1.asmx I see the page that list the services methods.

If I try testserver/Service1.asmx/HelloWorld I get an error. How can I get the service running or call the HelloWorld method.

I have spent two and a half days googling, reading and watching videos trying to figure I out what I need to do or what I am doing wrong.

推荐答案

服务正在运行，你只是没有正确访问它。



你可能正在获得一个错误如：对于意外以/ HelloWorld结尾的URL无法识别请求格式。



Web服务（必然）的行为与常规网页不同。例如，当您导航到网页时，您的浏览器正在执行 GET 请求。



Hello World Web服务不允许 GET 请求。如果您转到 http：// localhost：8801 / Service1.asmx？op = HelloWorld （将端口更改为运行服务的任何端口），您将获得一个页面像这样：

它向您展示了三种与Web服务交互的不同方式。



如果单击调用按钮，浏览器将执行 POST 请求，这是什么Web服务期待。



我建议使用 Fiddler [ ^ ]构建可以发送到Web服务器的查询，并看到原始响应。

The service is running, you're just not accessing it correctly.

You're probably getting an error like: Request format is unrecognized for URL unexpectedly ending in '/HelloWorld'.

Web services don't (necessarily) behave like regular web pages do. For example, when you navigate to a web page your browser is performing a GET request.

The Hello World web service goes not allow GET requests. If you go to http://localhost:8801/Service1.asmx?op=HelloWorld (change the port to whatever port your service is running on) you will get a page like this:

<img src="http://www.codeproject.com/script/Membership/Uploads/1740717/Screenshot_2014-06-12_12.01.53.png" width="600" />

It shows you three different ways to interact with your web service.

If you click the Invoke button, your browser will perform a POST request, which is what the web service is expecting.

I recommend using Fiddler[^] to construct queries that you can send to a web server, and see the raw response.
