Question

有没有办法在http.request of angular 2+中同时发送FormData和json对象？我需要angular2 +的解决方案，而不是angularjs。

let data = {id: 1, name: 'test'};
let formData = new FormData();
formData.append('fileData', file); //file from inputfile

let headers = new Headers();
headers.append('Accept', 'application/json');

let options =  new RequestOptions({ headers: headers });
options.method = 'POST';
options.body = data; //data is my object

//options.formData= formData; //formData is my FormData with file data to upload

this.http.request(url, options);

Answer 1

您必须像下面的示例一样在“ formData”对象上传递文件和JSON对象：

public submitForm(picture: File, data: any): Observable<any> {
 const formData = new FormData();
 formData.append('picture', picture);
 formData.append('data', JSON.stringify(data));
}

Answer 2

您应该将文件附加到正文。

let options =  new RequestOptions({ headers: headers });
options.method = 'POST';
options.body = data;
options.body.append('file', formData);

然后提出请求

this.http.request(url, options);

Angular 2+使用Json数据+ FormData发送请求
