webapi 跨域 (MVCWeb API: 405 method not allowed问题 )

使用webapi cors

1.安装包:Install-Package Microsoft.AspNet.WebApi.Cors –IncludePrerelease

2.在webapiconfig.cs中增加如下代码。

var cors = new EnableCorsAttribute("*", "*", "*");
            config.EnableCors(cors);

  

3.ajax请求示例代码

        $.ajax({
            url: 'http://127.0.0.1:8080/Api/Areas/XfFeedBack/PostFeedBack',
            //url: '/Api/Areas/XfFeedBack/PostFeedBack',
            type: "POST",
            data: JSON.stringify(obj),
            datatype:"json",
            contentType: "application/json; charset=utf-8",
            headers: {
                "signature": "xunfast@123!"
            },
            success: function (data) {
                console.log(data);
            }
        });
  $.ajax({
            //url: "http://127.0.0.1:8080/Api/Areas/SysNewsInfo/GetNewsInfoPage?pageIndex=1&pageSize=10&title=''&type=0",
            url: "/Api/Areas/SysNewsInfo/GetNewsInfoPage?pageIndex=1&pageSize=10&title=" + $("#title").val() + "&type=0",
            type: "GET",
            datatype: "json",
            headers: {
                "signature": "xunfast@123!"
            },
            success: function (data) {
                console.log(data);
            }
        });
//单个传参,引号不用给具体名称,给名称反而值传不过去(不清楚原因)
        $.post('http://127.0.0.1:8080/Api/Areas/SysNewsInfo/NewsInfoById', { "": 1 }, function (data) {
            console.info(data);
        });
