前端传递数据到后台的两种方式;创建一个map或者创建一个FormData对象

getAllDeptAllUsers(){
const modleCode = {'auditMenuId': this.auditMenuId,
'enterpriseId': this.$store.getters.enterpriseId};
deptJs.getAllDeptAllUsers(modleCode).then(res=>{
this.departmentList = res.data;
})
},

handleUploadChange(file, fileList) {
if(this.auditors == ''||this.auditors == null){
this.$message.error('上传前请先选择审核人')
return
}
if (file.name.lastIndexOf('.') < 0) {
this.$message.error('上传文件只能是xls、xlsx格式!')
return
}
const testMsg = file.name.substring(file.name.lastIndexOf('.') + 1).toLowerCase()
const extensionXLS = testMsg == 'xls'
const extensionXLSX = testMsg == 'xlsx'
if (!extensionXLS && !extensionXLSX) {
this.$message.error('上传文件只能是xls、xlsx格式!')
return
}
const isLt2M = file.size / 1024 / 1024 < 2
if (!isLt2M) {
this.$message.error('上传文件不能超过 2MB!')
return
}
console.log('import continue')
this.importLoading = true
this.importDisabled = true
const data = new FormData()
data.append('file', file.raw)
data.append('ids',this.auditors)
data.append('mesNodeNo',this.dataObj.mesNodeNo)
Node.importExcel(data).then(response => {
if (response.success == true) {
this.open2(response.msg)
this.importLoading = false
this.importDisabled = false
this.getList()
} else {
this.open2(response.msg)
this.importLoading = false
this.importDisabled = false
}
}).catch(() => {
this.open2('抱歉，导入失败')
this.importLoading = false
this.importDisabled = false
})
},
