1.  在webapi/webservice/wcf 项目中添加 Global.asax
2.  在Application\_BeginRequest方法中添加如下代码：

复制代码

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept, Authorization");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }

3. 如果是webservice项目的话，在webconfig->[system.web][] 节点下添加如下节点：

1.  ajax get方式调用webapi：

复制代码

$.ajax({  //ajax get方式调用webapi
                    type: "GET",
                    contentType: 'application/json',
                    url: 'http://localhost:8082/api/Patient/GetPatientInfoById',
                    data: { Id: "4343BF1C-5FD9-4ACE-BD90-26ED29C503C8" },
                    dataType: 'json',
                    success: function (data) {
                        console.log(data);
                    },
                    error: function (xhr) {
                        console.log(xhr.responseText);
                    }
                })

复制代码  
5. ajax POST方式调用webapi

复制代码

$.ajax({
                    type: "POST",
                    contentType: 'application/json',
                    url: 'http://localhost:8082/api/Patient/SavePatient',
                    data: JSON.stringify(model),
                    dataType: 'json',
                    success: function (data) {
                        console.log(data);
                    },
                    error: function (xhr) {
                        console.log(xhr.responseText);
                    }
                })

                    url: 'http://localhost:8003/PatientService.asmx/GetPatientInfoByEmpiId',
                    data: { empiId: "4343BF1C-5FD9-4ACE-BD90-26ED29C503C8" },        //encodeURI
                    dataType: 'xml',
                    success: function (data) {
                        console.log(data);
