在 VUE.JS 中传递多个参数问题

Question

I am trying to get data by passing multiple ids as param.But the params i am passing is going as array which i don't want.

Example:

Current data: The api is returning param as details?ids[]=123&ids[]=245

Expected data: I would like to pass the param as details?ids=123&ids=245

  const postRes = await axios.post('employee/departments', this.details);
  const getRes = await axios.get('employee/departments',
     { params: { ids: postRes.map(i=>i.id)},
  });
  this.$emit('fileDetails', getRes.data);

You could serialize the parameters yourself:

1. Map each object into a string, containing 'ids=' prefixed to the object's id .
2. Join the resulting array with a & delimiter.

const params = postRes.map(i => 'ids=' + i.id) 1️⃣
                      .join('&') 2️⃣
const getRes = await axios.get('employee/departments?' + params)

Run this snippet for example output:

 const postRes = [{ id: 11 }, { id: 22 }, { id: 33 }] const url = 'employee/departments?' + postRes.map(i => 'ids=' + i.id).join('&') console.log(url)
