Question

我在发布CORS请求时遇到了特定于chrome的问题。请求始终在OPTIONS的飞行前请求中失败。在IE 11中，根本不发送飞行前请求。

我的请求是使用jQuery发送的 -

$.ajax({
        url: "http://localhost/Family/MessengerService.svc",
        crossdomain: true,
        headers: {
            "SOAPAction": '"http://home/FamilyConnect/MessengerService/IMessengerService/Conversation"',
        },
        type: "POST",
        dataType: "xml",
        data: soapRequest,
        processData: true,
        complete: function (xmlHttpResponse, status) {
            if (status == 'success') {
              //Code to parse the return value.
            }
        },
        contentType: "text/xml; charset=\"utf-8\""
    });

我的请求标题是这个 -

OPTIONS /Family/MessengerService.svc HTTP/1.1
Host: localhost
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Request-Method: POST
Origin: http://localhost:51481
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.111 Safari/537.36
Access-Control-Request-Headers: accept, soapaction, content-type
Accept: */*
Referer: http://localhost:51481/Ping.html
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8,fr;q=0.6

我收到的回复标题是 -

HTTP/1.1 400 Bad Request
Cache-Control: private
Server: Microsoft-IIS/8.5
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
Access-Control-Allow-Origin: http://localhost:51481
Access-Control-Allow-Headers: accept, soapaction, content-type
Access-Control-Allow-Methods: POST, GET, PUT, DELETE, OPTIONS

服务配置文件具有以下配置 -

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="http://localhost:51481"/>
        <add name="Access-Control-Allow-Headers" value="accept, soapaction, content-type"/>
        <add name="Access-Control-Allow-Methods" value="POST, GET, PUT, DELETE, OPTIONS"/>
      </customHeaders>
    </httpProtocol>
    <modules runAllManagedModulesForAllRequests="true" />
    <directoryBrowse enabled="true" />
 </system.webServer>

我无法弄清楚为什么飞行前请求失败了？请求失败，HTTP错误代码400 - 错误请求。从请求和响应标头，我猜我从jQuery发送的请求很好。我应该查看我的IIS 8.5配置吗？如果是这样我该怎么办？搜索SO和Google会产生更多结果，其中服务是RESTful，数据交换模式是JSON或JSONP。现在，是否应该表示带有SOAP协议的Xml不适合CORS请求？
