jquery ajax POST/GET 请求至 ASP.NET WebAPI
1.注意要点:ajax提交请求的dataType参数、contentType参数值应该分别为
dataType: 'json' 和 contentType: 'application/json;charset=utf-8'
不然会报js跨域啊,Method 错误啊 等等一些乱七八糟的js错误.
下面直接上代码:
前端代码:
1 <!DOCTYPE html> 2 3 <html xmlns="http://www.w3.org/1999/xhtml"> 4 5 <head runat="server"> 6 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 7 <title></title> 8 <script src="js/jquery-2.2.3.min.js"></script> 9 <script type="text/javascript"> 10 $(function () { 11 $('#getData').click(function () { 12 $.ajax({ 13 url: 'http://localhost:58737/api/userInfo/getlist', 14 type: 'get', 15 dataType: 'json', 16 contentType: 'application/json;charset=utf-8', 17 success: function (data) { 18 //以表格的形式在浏览器控制台显示数据,IE下不支持 19 console.table(data); 20 } 21 }); 22 }); 23 24 $('#test').click(function () { 25 var school = {}; 26 school.SchoolID = 1; 27 school.SchoolName = "学校1"; 28 var students = []; 29 for (var i = 0; i < 3; i++) { 30 var student = {}; 31 student.StudentID = (i + 1); 32 student.StudentName = "学生" + (i + 1); 33 student.SchoolID = 1; 34 students.push(student); 35 } 36 school.Students = students; 37 console.log(JSON.stringify(school)); 38 $.ajax({ 39 url: 'http://localhost:58737/api/Test/AddSchool', 40 type: 'post', 41 dataType: 'json', 42 contentType: 'application/json;charset=utf-8', 43 data: JSON.stringify(school), 44 success: function (data) { 45 console.table(data); 46 }, 47 error: function () { }, 48 beforeSend: function () { }, 49 complete: function () { } 50 }); 51 }); 52 }); 53 </script> 54 </head> 55 56 <body> 57 <form id="form1" runat="server"> 58 <div> 59 <input type="button" value="跨域获取数据" id="getData" /> 60 <br /> 61 <hr /> 62 <input type="button" value=" Test " id="test" /> 63 </div> 64 </form> 65 </body> 66 67 </html>
后台控制器代码:
