java - 使用 Apache Camel 访问正确的 URL 时出现响应代码 302

我正在使用 Apache Camel 访问 Web 服务，但在调用 .NET Web 服务时遇到了奇怪的问题。

这是Camel发送的POST请求:

ID: 1
Address: http://<domainName>/<pathToService>.asmx
Encoding: UTF-8
Http-Method: POST
Content-Type: text/xml
Headers: {Accept=[*/*], breadcrumbId=[ID-someId-1449849054155-0-1], SOAPAction=["http://<someNamespace>/<SoapActionName>"]}
Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body>/soap:Body></soap:Envelope>

这就是响应:

ID: 1
Response-Code: 302
Encoding: UTF-8
Content-Type: text/html; charset=utf-8
Headers: {Cache-Control=[private], Content-Length=[223], content-type=[text/html; charset=utf-8], Location=[/<somePath>/CustomError.htm?aspxerrorpath=/<pathToService>.asmx], Persistent-Auth=[true], Server=[Microsoft-IIS/7.5], X-AspNet-Version=[4.0.30319], X-Powered-By=[ASP.NET], X-UA-Compatible=[IE=7]}
Payload: <html><head><title>Object moved</title></head></html>

当我在浏览器中请求“http://domainName/pathToService”时，我看到了正确的答案。

当我请求“http://domainName/pathToService.asmx?wsdl”时，我将获取 wsdl 文件。

如果我将 SoapActionName 更改为不正确的值，我会得到

"java.lang.IllegalArgumentException: Can't find the BindingOperationInfo with operation name ..."

当然，这也是正确的行为。

我认为我需要调整 Camel 以使其能够与 .NET Web 服务一起使用。

但是如何呢？

Camel 配置(全部在 Spring DSL 中):

    <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="exceptionHandler" class="...ExceptionHandler"/>

<cxf:cxfEndpoint id="wsEndpoint"
                 address="${ws.host}/service.asmx"
                 serviceClass="pathToServiceClass"
                 loggingFeatureEnabled="true"
                 endpointName="endpointName">
    <cxf:outInterceptors>
        <ref bean="loggingOutInterceptor"/>
    </cxf:outInterceptors>
    <cxf:inInterceptors>
        <ref bean="loggingInInterceptor"/>
    </cxf:inInterceptors>
    <cxf:properties>
        <entry key="dataFormat" value="POJO"/>
    </cxf:properties>
</cxf:cxfEndpoint>

<http:conduit name="{serviceClass}endpointName.http-conduit">
    <http:authorization>
        <sec:UserName>domain\username</sec:UserName>
        <sec:Password>password</sec:Password>
        <sec:AuthorizationType>NTLM</sec:AuthorizationType>
    </http:authorization>
</http:conduit>

<camelContext xmlns="http://camel.apache.org/schema/spring">

    <route id="mainRoute">
        <from uri="file://inbox"/>
        <setHeader headerName="operationName">
            <constant>AcquireTicket</constant>
        </setHeader>
        <to uri="cxf:bean:wsEndpoint" pattern="InOut"/>
        <onException>
            <exception>java.lang.Exception</exception>
            <process ref="exceptionHandler"/>
        </onException>
        <to uri="log:mylog?Level=INFO"/>
    </route>
</camelContext>

我使用 JUnit 调用 Camel:

    @Test
public void testWebservice() throws Exception {
    ... 
   forming request
   ...

    context.getRouteDefinition("mainRoute")
            .adviceWith(context, new AdviceWithRouteBuilder() {
                @Override
                public void configure() throws Exception {
                    replaceFromWith("direct:in");
                }
            });
    context.start();


    ProducerTemplate template = context.createProducerTemplate();
    template.sendBody("direct:in",request);
}

我尝试在没有 Camel 的情况下使用 Apache HttpClient 的请求 Web 服务:

    DefaultHttpClient httpClient = new DefaultHttpClient();
    httpClient.getAuthSchemes().register(AuthPolicy.NTLM,new JCIFSNTLMSchemeFactory());
    httpClient.getAuthSchemes().register(AuthPolicy.SPNEGO,new JCIFSNTLMSchemeFactory());
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    NTCredentials ntCredentials = new NTCredentials(USERNAME, PASSWORD,
            InetAddress.getLocalHost().getHostName(), DOMAIN);
    HttpHost target = new HttpHost(HOST,80,"http");
    credsProvider.setCredentials(new AuthScope(target.getHostName(), target.getPort(),
            AuthScope.ANY_REALM, "NTLM"), ntCredentials);
    httpClient.getCredentialsProvider().setCredentials(AuthScope.ANY, ntCredentials);

    HttpPost post = new HttpPost(URL);

    post.addHeader("SOAPAction", SOAP_ACTION);
    post.addHeader("Content-Type",CONTENT_TYPE);
    post.addHeader("Accept-Encoding",ACCEPT_ENCODING);
    HttpEntity httpEntity = new StringEntity(getShortText());
    post.setEntity(httpEntity);

    HttpResponse response = httpClient.execute(post);

这是 Camel 创建的最后一个 POST 请求(3 个 NTLM 请求中的 3 个):

    POST /<pathToService>.asmx HTTP/1.1
    Content-Type: text/xml; charset=UTF-8
    Accept: */*
    SOAPAction:<someNamespace>/<SoapActionName>
    User-Agent: Apache CXF 3.1.4
    Cache-Control: no-cache
    Pragma: no-cache
    Host: localhost:8013
    Connection: keep-alive
    Content-Length: 269
    Authorization: NTLM <Token>

Apache HttpClient 使用上述代码创建了最后一个(3 个 NTLM 请求中的 3 个)POST 请求:

    POST /<pathToService>.asmx HTTP/1.1
    Content-Type: text/xml; charset=utf-8
    Accept-Encoding: gzip,deflate
    SOAPAction:<someNamespace>/<SoapActionName>
    User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

    Host: localhost:8013
    Connection: Keep-Alive
    Content-Length: 269
    Authorization: NTLM <Token>

这两个请求看起来与我相同，但 IIS 对 Camel 请求的响应是 HTTP 302，IIS 对 Apache HttpCLient 的响应是 HTTP 200。

主机是 localhost:8013 因为我使用监听器来分析 HTTP 流量，该监听器将所有请求转发到远程服务器。

最佳答案

因为您的浏览器可以遵循位置 header 的 302 重定向。

您得到的响应是 HTTP 302，它是基于位置 header 的重定向。所以你需要告诉Camel跟随302并从location header中获取URI。
