JQuery访问

$.ajax({
                type: "get",
                dataType: ‘json‘,//服务器返回json格式数据
                contentType: ‘application/json‘,//如果是针对[FromBody]string 参数  contentType 需要注释掉，不然会接收不到值
                url: "http://localhost:10450/api/EmpInfo/GetWebName",
                data:  { name: "用户名", pwd: "用户密码" } ,
                headers: { Authorization: "lzsin" },

                success: function (data, response, status) {

                    alert(data);

                },
                error: function (data) {
                    console.log(data);
                    alert(‘失败!‘ + data["responseText"], data, ‘warning‘);

                }
