Question

我有一个在特定端口上运行的仪表板应用程序。

Angular应用程序在不同的端口上运行。

根据一些文档，我已经使用了代理。

这是proxy.conf.json文件中的内容

{
  "/apik/*": {
    "target": "http://localhost:8123/dashboard",
    "secure": false
 }
}

在ts文件中，我将网址设置为

url = 'apik/'

在HTML文件中，我使用iFrame如下打开仪表板

<iframe [src]="url" style="width: 100%;height: 500;border: none;"></iframe>

但是我遇到以下错误

ERROR Error: unsafe value used in a resource URL context (see http://g.co/ng/security#xss)

我尝试如下使用HTML中的消毒剂

<iframe [src]="sanitizer.bypassSecurityTrustResourceUrl(url)" style="width: 100%;height: 500;border: none;"></iframe>

但这会两次打开同一页面。

我正在使用以下代码

ng serve --proxy-config proxy.conf.json

这正确吗？

能请你帮忙吗？

尝试一下

instance NFData Op where
  -- (seq/deepseq) x y is defined by
  -- "if you want to evaluate (seq/deepseq) x y to WHNF, then you must
  -- evaluate x to WHNF/NF, then evaluate y to WHNF."
  -- but e.g. Add is already in WHNF and NF, so seq Add and deeqseq Add are no-ops
  -- the actual evaluation is already finished by the case in rnf's equations
  -- you could even write rnf x = x `seq` (), but I think it's best to be explicit
  rnf Add = ()
  rnf Sub = ()
  rnf Mul = ()
  rnf Div = ()

instance NFData Expr where
  rnf (Val a)     = a `deepseq` ()
  -- rnf o, rnf l :: ()
  -- WHNF and NF are the same thing for the type (); all constructors are nullary
  -- therefore (deepseq (rnf x) y) = seq (rnf x) y
  -- but then seq (rnf x) y = deepseq x y {by definition}
  rnf (App o l r) = o `deepseq` l `deepseq` rnf r

然后...

public url: string;

constructor(private sanitizer: DomSanitizer){
   this.url = this.sanitizer.bypassSecurityTrustResourceUrl('apik/');
}

Angular iFrame和反向代理
