前端

 import axios from 'axios' import qs from 'qs' axios.post("/getByUserIds", qs.stringify( {"userIds": userIds}, //userIds=["1","2","3"] {indices: false}) //该参数控制影响后台接收，参数传递格式(userIds=1&userIds=2&userIds=3) ).then( function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

后端

 @RequestMapping(value = "/getByUserIds", method = RequestMethod.POST)public Result getByUserIds(@RequestParam("userIds") String[] userIds) { System.out.println(userIds);}

qs.stringify 将对象序列化为URL的形式，以&拼接。与qs.parse()相对应

//indices格式qs.stringify({userIds: [1, 2, 3]}, { indices: false }) //形式： userIds=1&userIds=2&userIds=3qs.stringify({userIds: [1, 2, 3]}, {arrayFormat: ‘indices‘}) //形式： userIds[0]=1&userIds[1]=2&userIds[2]=3qs.stringify({userIds: [1, 2, 3]}, {arrayFormat: ‘brackets‘}) //形式：userIds[]=1&userIds[]=2&userIds[]=3qs.stringify({userIds: [1, 2, 3]}, {arrayFormat: ‘repeat‘}) //形式： userIds=1&userIds=2&userIds=3
