通过表单数据将Angular 2文件上传到REST API

Question

When using form-data to upload file with other form inputs, it does not accept the integer. When we pass the integer values, it converts as string. But i need to pass integer ie numbers, string and file upload to REST API by form-data. Can anyone please suggests for this? Thanks in advance.

 Save(model: yourmodalarray[]): Observable<any> {

        var formData: FormData = new FormData();

        formData.append('id', '');
 const headers = new Headers({
            'Accept': 'application/json',
            'enctype': 'multipart/form-data'
        });
        const options = new RequestOptions({ headers: headers });


        return this._http
            .post(this._baseUrl + 'Save', formData, options)
            .map(res => <any>res.json())
            .catch(this.handleError);

    }

Use append method to pass the integer value.i hope this help...
