Shr*_*kar 8 base64 image ionic-framework ionic3 angular
我想为个人资料图片显示base64图像.图像作为二进制数据存储在数据库中,我使用btoa()将这个二进制数据转换为base64.现在我想将这个base64图像绑定到img src我尝试了很多方法但它不起作用,请帮助这里是我的代码
profile.ts代码:
profilePicture(binImage)
{
if(binImage != null)
{
var imageData = btoa(binImage);
//console.log("Base64 Image: ",imageData);
this.displayImage = imageData;
}
}

它显示错误"清理不安全的url值safevalue必须使用[property] = binding"
在模板中使用之前添加消毒剂并清理网址
import { DomSanitizer } from '@angular/platform-browser';
...
constructor( private sanitizer: DomSanitizer, .... ) {}
...
profilePicture(binImage)
{
if(binImage != null)
{
var imageData = btoa(binImage);
//console.log("Base64 Image: ",imageData);
this.displayImage = this.sanitizer.bypassSecurityTrustUrl("data:Image/*;base64,"+imageData);
}
