我正在向我的后端发送一个帖子请求以接收一个excel文件。我可以在邮递员中看到我的后端正在发送excel,但在角度我无法下载它。有任何想法吗?这是我的HTML代码:
<button (click)="excell()">Export Excell</button>
这是我的服务类:
export class HomeComponent implements OnInit {
constructor(private data: DataService , private formBuilder: FormBuilder ) { }
ngOnInit() {
}
excell(){this.data.excell()
console.log("sent")}
}
这是我请求后端的数据类方法:
excell() {
const headers = new HttpHeaders();
console.log("sentin")
headers.set('Content-Type', 'application/json; charset=utf-8');
return this.http.post(this.baseUrl + '/Excel', { headers: headers })
}
textFileDownload() {
this.httpClient.get('url', {responseType: 'arraybuffer'})
.subscribe((res) => {
this.writeContents(res, 'test.txt', 'text/txt'); // file extension
});
}
writeContents(content, fileName, contentType) {
const a = document.createElement('a');
const file = new Blob([content], {type: contentType});
a.href = URL.createObjectURL(file);
a.download = fileName;
a.click();
}
