public formdata = new FormData();
onSubmit() {
this.resetform(); //Order matters here
let headers: any = new Headers();
headers.append('Content-type', 'undefined');
formData.append("selectFile", this.formData);
const req5 = new HttpRequest('POST', 'url as hosted on TOMCAT', formData,
reportProgress: true,
responseType: 'text'
});
return this.httpClient.request(req5).subscribe(e => {(
console.log(e);
)}
}
resetform() {
this.formData = new FormData();
}
我希望它能解决您的问题！
