Ajax 2 ways to submit
get
$.ajax({
type: "Get",
url: "/xiangmu/user/preparPayWeixin/result/"+out_trade_no+".action",
success: function(data) {
if(data.xxx== 'success'){
// specific business
}
},
error: function(err) {
}
});
post
$.ajax({
type: "POST",
url: "Service/SimpleData",
contentType: "application/json", //must have
dataType: "json", //represents the return value type, not required

alert(jsonResult);
Corresponding 2 kinds of spring mvc
corresponding to the get method
@Controller
@RequestMapping("/user/preparPayWeixin")
public class PreparPayNotifyWeixinController extends BaseController{
@ResponseBody
@RequestMapping(value="result/{sn}",produces = "text/html;charset=UTF-8",method = {RequestMethod.POST, RequestMethod.GET})
public String getResult(@PathVariable("sn") String sn){
String re = "";
if(payStatus.get(sn) != null && "success".endsWith(payStatus.get(sn))){
re = "{\"data\":\"success\"}";
}else{
re = "{\"data\":\"fail\"}";
}
return re;
}
Description: @ResponseBody: The json data returned to ajax is annotated with this
result/ {sn} : {sn} is a path parameter and needs to be used together with @PathVariable("sn")
method = {RequestMethod.POST, RequestMethod.GET}: Receive get and post methods
produces = "text/html;charset=UTF-8": matches the request header, Accept: text/html, not often used
Spring mvc also has a common annotation: @RequestParam( value= "aa" , required= true )String title
Mvc corresponding to post mode
@RequestMapping(value = "/SimpleData",method=RequestMethod.POST)
@ResponseBody
public ActionResult SimpleData(string foo, string bar){
return Json("SimpleData", JsonRequestBehavior.AllowGet);
}
