我已阅读this post和this article。我相信我已经完成了所有建议:将管道添加到共享的模块中。
但是,无论我做什么,我都无法获取模板来查找我创建的管道。我的应用程序已经有一个共享模块,其他模块导入,所以我创建管道并将其添加到共享模块:
我用ng g pipe /shared/pipes/safe --flat --module shared --spec=false
在SharedModule中,我还将其添加到declarations
和providers
。
一切都在运行,但我尝试使用管道,如:
<iframe width="600" height="360" [src]="video.acf.youtube_url | safe: 'url'" frameborder="0" allowfullscreen></iframe>
我刚收到错误
Error: Uncaught (in promise): Error: Template parse errors: The pipe 'safe' could not be found
管道本身就是
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml, SafeStyle, SafeScript, SafeUrl, SafeResourceUrl } from '@angular/platform-browser';
@Pipe({
name: 'safe'
})
export class SafePipe implements PipeTransform {
constructor(protected sanitizer: DomSanitizer) { }
public transform(value: any, type: string): SafeHtml | SafeStyle | SafeScript | SafeUrl | SafeResourceUrl {
switch (type) {
case 'html': return this.sanitizer.bypassSecurityTrustHtml(value);
case 'style': return this.sanitizer.bypassSecurityTrustStyle(value);
case 'script': return this.sanitizer.bypassSecurityTrustScript(value);
case 'url': return this.sanitizer.bypassSecurityTrustUrl(value);
case 'resourceUrl': return this.sanitizer.bypassSecurityTrustResourceUrl(value);
default: throw new Error(`Invalid safe type specified: ${type}`);
}
}
}
答案 0 :(得分:7)
您还需要在 SharedModule
导出下添加
exports: [
SafePipe
]
