base64或者blob路径图片转File上传

objectURLToBlob(url) {
			return new Promise(resolve => {
				const http = new XMLHttpRequest()
				http.open('GET', url, true)
				http.responseType = 'blob'
				http.onload = function(e) {
					if (this.status == 200 || this.status === 0) {
						resolve(this.response)
					}
				}
				http.send()
			})
		},

async setCos() {

			let imgObj= await this.objectURLToBlob(this.imageBase64),  //base64  || blob

			let imageBase64File = new File([imgObj], '', {
				type: imgObj.type
			})
			// 上传图片到服务器....
			
		},
