axios发送post请求,提交图片类型表单数据方法

<input type="file" @change="upload" ref="upload">

const userUploadAtt = (File,config) => axios.post("接口",File,config)

let input = this.$refs.upload 创建一个空的FormData对象 let data = new FormData();使用FormData.append来添加键/值对到表单里面;data.append('file', input.files[0]);upload(){ userUploadAtt(data,{headers: {'Content-Type': 'multipart/form-data'}}).then((response)=>{  this.headPhoto = response.data[0].msg.url; }).catch(()=>{ })}

axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=UTF-8'post请求时候表单上传不需要引入qs.stringify()
