The case is no, here comes the case:

//backend interface
 /**
 *post/get
 * parameter value 1 2 3
 * return data type json\xml\html
 **/
 function resful_1() {
 
 bracket
 
 $.ajax({
 type: "post/get",
 url: "admin/user/resful_1",
 data: {id：id,name:name},
 success: function (data) {
 if(data.state==200){
 alert(data.msg);
 }else{
 Alert ('request failed' plus data.msg);
 bracket
 bracket
 });

Just like the common interface, the agreement is good.Url address、Request mode、Request parameters、Return value type、Return value tagJust wait
