uni小程序实现文件上传

uni.chooseImage({
				count: 1, //默认9
				sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
				sourceType: ['album'], //从相册选择
				success: (chooseImageRes) => {
					console.log('tempFilePaths', chooseImageRes);
					const filePath = chooseImageRes.tempFiles[0].path;
					const fileSize = chooseImageRes.tempFiles[0].size;
					if (fileSize > 2 * 1024 * 1024) {
						that.$refs.uToast1.show({
							message: '文件大小不能超过2M',
							type: 'error'
						});
						return;
					} else {
						uni.uploadFile({
							url: 'https://.......',
							filePath: filePath,
							name: 'file',
							success: function (res) {
								var data = res.data;
								data = JSON.parse(data);
								that.formLabelAlign.profilePhoto = data.data.url;
								updateStudent(that.formLabelAlign).then((res) => {
