我想将用户 ID 发送到 Controller ,以便获得真实姓名。例如:

发送:1 3 5结果:汤姆·贾斯汀·阿尔伯

@RequestMapping(value="/batch",method=RequestMethod.GET)
public String getMore(@RequestBody String userids) {
String result="";
String[] ids=userids.split(" ");
for (String id : ids) {
Users users = usersService.findById(Integer.parseInt(id));
if(users!=null) {
result= (result+" " + users.getRealname()).trim();
}
}
return result;
}

ajax代码如下

var urln="http://localhost:8080/users/batch";
$.ajax({
type: "GET",
url: urln,
data:‘1 3’,
dataType:'text',
success: function (data) {
alert(data);
},
error: function (XMLHttpRequest, textStatus,
errorThrown) {
alert(textStatus);
}
});

显示错误如下

Required request body is missing: public java.lang.String com.coolspen.rjb.controller.UsersController.getMore(java.lang.String)

但是 postman 进展顺利,结果如下:

postman goes well

最佳答案

你可以看到这个链接QueryParam用于使用 GET 发送请求。

http://localhost:8080/users/batch?userids=1 3
