JS中formdata和其他参数一起传入服务示例

handleFileUpload(event) {

event.preventDefault()

//获取文件信息

this.formData = new FormData()

let file = this.$refs.file.files

this.formData.append('fingerprint', file[0])

this.ruleForm.fingerprint = file[0]['name']

event.srcElement.value = ""

},

submitForms() {

const parms = {

    productName: this.ruleForm.productName,

    productType: this.ruleForm.productType,

    startTime: (this.ruleForm.startTime ? this.ruleForm.startTime.getTime() : ''),

    endTime: (this.ruleForm.endTime ? this.ruleForm.endTime.getTime() : '')

}

const json = JSON.stringify(parms)

// 将 json 字符串转化为 Blob 对象

const blob = new Blob([json], {

    type: 'application/json',

})

this.formData.append('request', blob)

this.$http({

url: this.$http.adornUrl('/auth/addAuth'),

method: 'post',

headers: {

    'Content-Type': 'multipart/form-data'

},

data: this.formData

}).then(({ data }) => {

if (data && data.code == '200') {

    this.$message({

        message: '申请授权成功',

        type: 'success'

    })

    this.getDataList()

} else {

    this.$message.error(data && data.message)

}

    this.isShowDialog = false

})

}
