My file download have ` PK z—LO‹Ý<

问题

I have the problem when I download the file.

I download the file with this text:

PK

In fact this is not the text that I want to download.

I tried this code: my service code:

  public download(id: string): Observable<any> {
    let params = new URLSearchParams();
    let headers = new Headers();
    headers.append('x-access-token', this.auth.getCurrentUser().token);
    headers.append('sale_id', id);
    headers.append('Content-Type', 'text/xml');
    headers.append('responseType', 'blob');
    return this.http.get(Api.getUrl(Api.URLS.download), {
      headers: headers,
     responseType: ResponseContentType.Blob,
    }).map(res => res.blob())
  }

my component code:

  exportExcel(id: string) {
    this.ss.download(id)
      .subscribe(data => { console.log(`excel data: ${data}`); FileSaver.saveAs(data, 'people-export.xlsx') },
        error => console.log("Error downloading the file."),
        () => console.log('Completed file download.'));
  }

my html code:

  <button>
<i class="fa fa-save" aria-hidden="true"(click)="exportExcel(item.sale_id)"></i>
  </button>

Please, I need your support. Thank you

回答1:

The PK at the beginning tells you, that this is a zipped file. Try to open this file with 7-zip or any other unzipping tool.

The zip-format was created by Phil Katz ("zip" was formerly known as "PKWARE") :-D

Jeroen Mostert is right: Modern Excel files (.xlsx) are zipped files. Changing their extension to .zip allows to open such a file within Explorer just as any other ZIP-file.

You find the Worksheet's data within the directory xl as sheet1 or sheet2
