ASMX不扔SOAP错误 [英] ASMX not throwing SOAP faults

问题描述

我的ASP.NET 3.5 Web服务（ASMX）不抛出异常作为SOAP错误。我所看到的一切说，这是默认的行为，但该矿发送所有异常信息为文本/平原。这是一个新的Web应用程序项目添加了一个服务。从开箱行为没有其他变化。我如何获得SOAP错误？

code：

  [WebService的空间（namespace =htt​​p://tempuri.org/）]
[WebServiceBinding（ConformsTo = WsiProfiles.BasicProfile1_1）
[System.ComponentModel.ToolboxItem（假）]
公共类的WebService：System.Web.Services.WebService
{
    [的WebMethod]
    公共字符串的HelloWorld（）
    {
        INT TEST1 = 0;
        INT测试2 = 5 / test1的;        返回的Hello World;
    }
}
 

结果：

  HTTP / 1.1 500内部服务器错误
服务器：ASP.NET开发服务器/ 10.0.0.0
日期：星期二，2011 GMT 21时39分23秒10月25日
的X ASPNET-版本：2.0.50727
缓存控制：私人
内容类型：text / plain的;字符集= UTF-8
内容长度：201
连接：关闭System.DivideByZeroException：试图除以零。
   在WebApplication.WebService.HelloWorld（）在C：\\ .... CS：23行
 

解决方案

ASMX Web服务将只与SOAP响应，如果请求是SOAP。该服务为您生成的测试页不包括SOAP请求信封：

  POST HTTP：//server/service.asmx/HelloWorld HTTP / 1.1
接受：* / *
内容类型：应用程序/ x-WWW的形式urlen codeD
内容长度：0
主持人：服务器
 

一个适当的SOAP请求是这样的：

  POST HTTP：//server/service.asmx HTTP / 1.1
内容类型：文本/ xml的;字符集= UTF-8
SOAPAction报：HTTP：//服务器/的HelloWorld
主持人：服务器
内容长度：283
期望：100-继续＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;肥皂：信封
    的xmlns：SOAP =htt​​p://schemas.xmlsoap.org/soap/envelope/
    XMLNS：XSI =htt​​p://www.w3.org/2001/XMLSchema-instance
    的xmlns：XSD =htt​​p://www.w3.org/2001/XMLSchema＆GT;
  ＆LT;肥皂：身体与GT;
    ＆LT;的HelloWorld的xmlns =HTTP：//服务器//＆GT;
  ＆LT; / SOAP：身体与GT;
＆LT; / SOAP：信封＆GT;
 

注意SOAPAction头字段和SOAP信封的内容。如果该请求是有效的SOAP请求的服务将与SOAP响应作出响应。对于初始例如，下面的SOAP错误是响应

My ASP.NET 3.5 web service (asmx) is not throwing exceptions as SOAP faults. Everything I've seen says this is the default behavior but mine is sending all exception information as text/plain. This is a new web application project with one service added. No other changes from out of the box behavior. How do I get SOAP faults?

Code:

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class WebService : System.Web.Services.WebService
{
    [WebMethod]
    public string HelloWorld()
    {
        int test1 = 0;
        int test2 = 5 / test1;

        return "Hello World";
    }
}

Result:

HTTP/1.1 500 Internal Server Error
Server: ASP.NET Development Server/10.0.0.0
Date: Tue, 25 Oct 2011 21:39:23 GMT
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Type: text/plain; charset=utf-8
Content-Length: 201
Connection: Close

System.DivideByZeroException: Attempted to divide by zero.
   at WebApplication.WebService.HelloWorld() in C:\....cs:line 23

解决方案

ASMX web services will only respond with SOAP if the request was SOAP. The testing page generated for you by the service doesn't include the SOAP request envelope:

POST http://server/service.asmx/HelloWorld HTTP/1.1
Accept: */*
Content-Type: application/x-www-form-urlencoded
Content-Length: 0
Host: server

A proper SOAP request looks like this:

POST http://server/service.asmx HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://server/HelloWorld"
Host: server
Content-Length: 283
Expect: 100-continue

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <HelloWorld xmlns="http://server/" />
  </soap:Body>
</soap:Envelope>

Notice the SOAPAction header field and the SOAP envelope content. If the request is a valid SOAP request the service will respond with a SOAP response. For the initial example, the following SOAP fault is the response:

HTTP/1.1 500 Internal Server Error
Date: Sat, 05 Nov 2011 16:55:17 GMT
Content-Type: text/xml; charset=utf-8
Content-Length: 695

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <soap:Fault>
      <faultcode>soap:Server</faultcode>
      <faultstring>
        System.Web.Services.Protocols.SoapException: Server was unable to process request. ---    &gt; System.DivideByZeroException: Attempted to divide by zero.
        at Service.HelloWorld() in C:\Test\Service.asmx.cs:line 35
        --- End of inner exception stack trace ---
      </faultstring>
      <detail />
    </soap:Fault>
  </soap:Body>
</soap:Envelope>
