获取到的base64图片不显示并且控制台报错Request Header Fields Too Large base64图片转file

1. 获取到的base64图片不显示并且控制台报错Request Header Fields Too Large

在获取的base64路径前添加：“data:image/jpeg;base64,”

const imgSrc = "data:image/jpeg;base64," + result.data.jpg_base64

具体参考：参考链接

2. base64图片转file

export const base64ImgtoFile = (dataurl, filename = "file") => {const arr = dataurl.split(",");const mime = arr[0].match(/:(.*?);/)[1];const suffix = mime.split("/")[1];const bstr = atob(arr[1]);let n = bstr.length;const u8arr = new Uint8Array(n);while (n--) {u8arr[n] = bstr.charCodeAt(n);}return new File([u8arr], `${filename}.${suffix}`, {type: mime,});
};
