There are multiple issues: 存在多个问题:
Access-Control-Allow-Origin: *
or specifically allowing your origin Access-Control-Allow-Origin: *
或明确允许您的来源,否则该请求将不起作用 GET
where as you should be using POST
, because in SOAP over HTTP the envelope must be in the request body. GET
,而应该使用POST
,因为在基于HTTP的SOAP中,信封必须位于请求正文中。 application/x-www-form-urlencoded
unless you set processData
to false. application/x-www-form-urlencoded
除非您将processData
设置为false。 Only setting contentType
will just make the header lie and doesn't actually change this. contentType
只会使标头撒谎,并且实际上不会更改此标头。 data
parameter is a string. data
参数是一个字符串,则不是这样。 It appears that your target domain is not allowing CORS, so it is impossible to do it directly from client-side. 您的目标域似乎不允许使用CORS,因此不可能直接从客户端进行。 You must use a server proxy to do the request.
您必须使用服务器代理来执行请求。
If they allowed CORS, you would do it like so: 如果他们允许CORS,您可以这样做:
var soapMessage = '<?xml version="1.0" encoding="utf-8"?>\
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">\
<soap12:Body>\
<login xmlns="http://tastygo.com/">\
<BBMID>string</BBMID>\
<Email>string</Email>\
<Password>string</Password>\
</login>\
</soap12:Body>\
</soap12:Envelope>';
$.ajax( "http://m.allaccesstnt.com/AATnTWebservices/Webservices/Userwebservice.asmx", {
contentType: "application/soap+xml; charset=utf-8",
type: "POST", //important
dataType: "xml",
data: soapMessage
});
But this will not work because the server does not allow OPTIONS, which the browser must use to determine whether a cross-origin request is allowed: 但这将不起作用,因为服务器不允许使用OPTIONS,浏览器必须使用OPTIONS来确定是否允许跨域请求:
OPTIONS http://m.allaccesstnt.com/AATnTWebservices/Webservices/Userwebservice.asmx 405 (Method Not Allowed)
The second problem is: 第二个问题是:
XMLHttpRequest cannot load http://m.allaccesstnt.com/AATnTWebservices/Webservices/Userwebservice.asmx. Origin http://stackoverflow.com is not allowed by Access-Control-Allow-Origin.
只需添加http://m.allaccesstnt.com/AATnTWebservices/Webservices/Userwebservice.asmx/ 测试并在Web服务器端添加标头
