Question

我正在尝试制作如下的ajax请求：

function updateLastSeen() {
    var url = 'http://my.url.com/conversation/' + $('#conversationId').val() + '/seen/' + $('#senderId').val();
    $.ajax({
        type: 'PUT',
        url: url,
        contentType: "application/json",
        success: function(result) {
            alert('Logged out')},
        error: function(result) {
            alert('error')
        }
    });
}

预检中的请求如下所示：

Request headers
OPTIONS http://my.url.com/conversation/3/seen/3 HTTP/1.1
Host: m.url.com
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Origin: null
Access-Control-Request-Method: PUT
Connection: keep-alive

这是回复

HTTP/1.1 200 OK
Date: Wed, 15 Apr 2015 06:16:54 GMT
Server: Apache
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: *
Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept
Keep-Alive: timeout=5, max=98
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/json

所以据我说它应该有效。但是，我得到一个错误，即Access-Control-Allow-Methods不允许使用Method PUT。

我也试过通过Postman查看后端是否有问题（这对我来说是完全模糊的）但是通过Postman它可以工作！那么我做错了什么？

邮递员的请求标头：

jQuery ajax请求PUT失败，但它正在与Postman合作
