如何将本地文件读入字符串

Question

I want to read a (svg) file in Angular 6 from assets into a string. I tried things like that:

  this._htmlClient.get('../../assets/images/chart1.svg').subscribe(data => { console.log('svg-file: ', data); }); 

But it does not work. The console.log is not written and I get a error

ERROR HttpErrorResponse {headers: HttpHeaders, status: 200, statusText: "OK", url: " http://localhost:4200/assets/images/chart1.svg ", ok: false,

The path is right. When i copy it into the browser I see my picture.

How I can get the file content into a string?

By default, the HttpClient expects the response to be JSON. If you want to get something else, you need to specify the type:

this._htmlClient.get('path', { responseType: 'text' })
  .subscribe(data => { console.log(data) });
