问题描述
服务器发出的响应如下:
Response from my server looks like following:
[{"coreGoalId":1,"title":"Core goal 1","infrastructure":"Sample Infrastructure","audience":"People","subGoals":null,"benefits":[{"benefitId":1,"what":"string","coreGoalId":1}],"effects":null,"steps":null,"images":[{"imagelId":1,"base64":"/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAYEBQYFBAYGBQYHBwYIChAKCgkJChQODwwQFxQYGBcU\nFhYaHSUfGhsjHBYWICwgIyYnKSopGR8tMC0oMCUoKSj/2wBDAQcHBwoIChMKChMoGhYaKCgoKCgo\nKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCj/wgARCAIWAe4DASIA\nAhEBAxEB/8QAHAABAAIDAQEB"}]}]
我试图显示其中返回的base64图像.
I am trying to display the base64 image returned in it.
在我的组件中:
ngOnInit() {
this.homeService.getGoals()
.subscribe(
goals => this.coreGoals = goals,
error => this.errorMessage = <any>error);
}
,然后在模板中:
<ul>
<li *ngFor="let goal of coreGoals">
{{goal.title}}
<img [src]="'data:image/jpg;base64,'+goal.images[0].base64 | safeHtml" />
</li>
</ul>
safeHtml是我创建的管道,如下所示:
Where safeHtml is a Pipe I created like following:
import { Pipe } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Pipe({name: 'safeHtml'})
export class SafeHtml {
constructor(private sanitizer:DomSanitizer){}
transform(html) {
return this.sanitizer.bypassSecurityTrustHtml(html);
}
}
这给了我Required a safe URL, got a HTML
错误.这是怎么了?如果我从<img />
中删除管道,那么它会显示不安全的网址.
This gives me Required a safe URL, got a HTML
error. What is going wrong here? If I remove the pipe from <img />
then it says unsafe url.
推荐答案
您将需要
bypassSecurityTrustResourceUrl(html);
代替
bypassSecurityTrustHtml(html);
