Question

我设法使用在线URL将图像上传到Facebook，但是，当我尝试使用file://path/to/image格式的本地图像时，出现错误

{"error":{"message":"(#100) url should represent a valid URL","type":"OAuthException","code":100}

可行吗？还是做错了？

async function upload_fb_image(photo) {

    return new Promise(resolve => {

        FB.api(PAGE_ID + '/photos', 'post', {
            message: 'Message',
            url: LINK_TO_IMAGE,
            published: false,
            caption: 'Ad',
            access_token: EXD_ACCESS_TOKEN
        }).then(data => { resolve(data) })
    })
}

为表单数据

我尝试作为答案中提到的表单数据...我收到ok响应，但是未返回图像ID，我得到了以下JSON作为响应

Answer 1

该URL必须是公共URL，而不是本地计算机中的某些URL。或者，您可以使用FormData：

const fileReader = new FileReader();
const file = document.getElementById('imageInput').files[0];

fileReader.onloadend = async () => {
    const photoData = new Blob([fileReader.result], {type: 'image/jpg'});
    const formData = new FormData();

    formData.append('access_token', pageAccessToken);
    formData.append('source', photoData);
    formData.append('message', 'some status message');

    let response = await fetch(`https://graph.facebook.com/${pageId}/photos`, {
        body: formData,
        method: 'post'
    });
    response = await response.json();
    console.log(response);
};
fileReader.readAsArrayBuffer(file);

Answer 2

最后使用以下方法解决了

 const formData = {
            access_token: EXD_ACCESS_TOKEN,
            source: fs.createReadStream("path/to/image"),
            published: 'false'
        }

        console.log('sendning request')

        request.post({ url: `https://graph.facebook.com/${PAGE_ID}/photos`, formData: formData }, function optionalCallback(err, httpResponse, body) {
            if (err) {
                return console.error('upload failed:', err);
            }

            resolve(body)
        });
