Project axios request to send post data type when stepped on Form Data data pit (set up after the request has not been successful header information sent in the past but not the type) Solution

Post projects on the rear end of the data transmission requirements of formdata,

• Then the first thing now setup request header ,, with many package ajax libraries may request header information provided herein as an example to axios

axios({
    url:this.dialog.add.upload_url,
    method:'post',
    data,
    headers:{
        'Content-Type':'application/x-www-form-urlencoded'
    }
}).then(res=>{
    if(res.status){
        this.$message.success("修改成功");
        this.mapping=[];
        this.dialog.add.show=false;
        this.getTableData();
    }
})

Here the object is a data

 let data = {
 		temp_name:"sjsj",
 		mapping:[{'sda':'dad'},{'sda':'dad'}]
 }

But in the past this type of transmission data is correct, but he is not formatted correctly so that the rear end of the received data might not be processed

A new solution FormData () but do not do as the data sent is in fact not formdata

let data=new FormData();
data.append("mapping",this.fileUploadData.mapping)
data.append("temp_name",this.fileUploadData.temp_name)
data.append("_id",this.fileUploadData._id)

Now let's look at network

That's all we want to help
