MockJs.mock (/ PROJECT/, {

"data|0-100":[
    {
        "id":"@guid()",
        "projectname":"@ctitle(3, 5)",
        "describe|0-1":"@cparagraph(1)",
        "user|1":"@cname",
        "startdate":"@date()",
        "enddate":"@date()",
        "fileList": [
            {
                "name": "@ctitle(3, 10).word", 
                "url": "@url"
            }
        ]
    }
]

})
I think that after the project starts, the simulated data of mockjs will not change, because each time the localhost:9090/PROJECT is added, deleted, changed or queried, this operation will trigger to refresh the data, resulting in different simulated data each time.

add:

this.axios({
              method:"post",
              url:url,
              data:data
 }).then().catch()

modify:

this.axios({
              method:"put",
              url:url+id,
              data:data
})

.
