如何避免添加前缀“unsafe”链接Angular-2？ [英] How to avoid adding prefix “unsafe” to link by Angular-2?

问题描述

我正在开发一个移动应用程序，使用 angular2 和 ionic 2 ，
我有3 按钮用于致电，短信和电子邮件如下所示

I am developing a mobile app using angular2 and ionic 2, I have 3 buttons for call, sms and email as below

          <a ion-button href="tel:{{contact.cellphone}}" color="primary">
            <ion-icon name="call"></ion-icon>
            Call
          </a>
          <a ion-button href="sms:{{contact.cellphone}}" color="secondary">
            <ion-icon name="text"></ion-icon>
            SMS
          </a>
          <a ion-button href="mailto:{{contact.email}}" color="dark">
            <ion-icon name="mail"></ion-icon>
            Email
          </a>

致电和电子邮件工作正常，但不是 sms ，似乎angular添加不安全： in-在我的表达的前面，它将变得像下面

Call and email are working fine, but not sms, it seems angular adds unsafe: in-front of my expression and it will become like below

<a color="secondary" ion-button="" ng-reflect-color="secondary" class="button button-md button-default button-default-md button-md-secondary" ng-reflect-href="unsafe:sms:[phone]" href="unsafe:sms:[phone]"><span class="button-inner">

即使我试过这个

      <a ion-button [attr.href]="'sms:'+contact.cellphone" color="secondary">
        <ion-icon name="text"></ion-icon>
        SMS
      </a>

仍然是同一个问题，

当我不要使用角度绑定它工作正常，例如像这样

When I don't use angular binding it's working fine, for example like this

          <a ion-button href="sms:[phone]" color="secondary">
            <ion-icon name="text"></ion-icon>
            SMS
          </a>

虽然它与angular有关但我也检查了我的 config.xml 和 sms

Although it's related to angular but also I checked my config.xml and sms is allowed there

<allow-intent href="tel:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />

更新

使用@Apuu解决方案后它变得像下面

Update

After using @Apuu solution it become like below

          <a ion-button [attr.href]="'sms:'+contact.cellphone | safeUrl" color="secondary">
            <ion-icon name="text"></ion-icon>
            SMS
          </a>

推荐答案

您可以创建管道服务来将不安全的网址更改为安全网址。

You can create a pipe service to change unsafe url to safe url.

创建名为的管道服务safe-url.pipe.ts 。

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Pipe({
  name: 'safeUrl'
})
export class SafeUrlPipe implements PipeTransform {
  constructor(private domSanitizer: DomSanitizer) {}
  transform(url) {
    return this.domSanitizer.bypassSecurityTrustResourceUrl(url);
}
}

然后在你的视图中使用。

示例：

Then use in your view.
Example :

<a ion-button [src]="'some_url' | safeUrl" color="secondary">
     <ion-icon name="text"></ion-icon>
     SMS
</a>

注意：不要忘记在您的应用中注入此管道服务.module.ts

NOTE : Don't forget to inject this pipe service in your app.module.ts

import { SafeUrlPipe } from './shared/safe-url.pipe'; //make sure your safe-url.pipe.ts file path is matching.

在节点模块声明部分。

@NgModule({ declarations: [SafeUrlPipe],...});
