从本地存储上传Facebook图像 [英] Facebook image upload from local storage

问题描述

我正在使用Facebook graph API将图像发布到页面上.

I'm using Facebook graph API to post an Image to a page.

 UploadImage() {

let params = {
  url: "https://www.facebook.com/images/fb_icon_325x325.png",
  published: true,
  access_token: this.accessToken
};

this.fb.api('/543337362691456/photos', 'post', params).then().catch(this.handleError); }

此代码运行完美.但我想从计算机中选择一个文件，然后将该图像上传到Facebook.为此，我如何将本地文件的url设置为

This code works perfectly. But I want to select a file from computer and upload that image to facebook. In order to do that, How I'm suppose to set the url of a local file to

url:" "

如果我只是选择文件路径，则会显示错误

if I just select the path of a file it gives an error

错误

推荐答案

url参数仅用于在线/公共照片，该照片必须已经在服务器上.看一下API参考，您也可以将它们作为multipart/form-data上传: https://developers.facebook.com/docs/graph-api/reference/page/photos/#Creating

The url parameter is for online/public photos only, the picture needs to be on a server already. Take a look at the API reference, you can also upload them as multipart/form-data: https://developers.facebook.com/docs/graph-api/reference/page/photos/#Creating
