HTML2Canvas---合成海報遇到問題總結 -开发者知识库

var userAgent = navigator.userAgent.toLowerCase();
var bIsIphoneOs = userAgent.match(/iphone os/i) == "iphone os";



if (bIsIphoneOs && userAgent.indexOf("safari") > -1 ) {
    this.imgUrl = URL.createObjectURL(this.base64ToBlob(canvas.toDataURL())) 
}


//base64轉blob
            base64ToBlob(code) {
                let parts = code.split(';base64,');
                let contentType = parts[0].split(':')[1];
                let raw = window.atob(parts[1]);
                let rawLength = raw.length;
     
                let uInt8Array = new Uint8Array(rawLength);
     
                for (let i = 0; i < rawLength;   i) {
                uInt8Array[i] = raw.charCodeAt(i);
                }
                return new Blob([uInt8Array], {type: contentType});
            },
