如何使用图形API将视频上传到我的Facebook页面？

Question

我一直在努力解释如何获得here和here获得的文档。我正在使用Facebook's Javascript SDK。

    async postVideo(page: IFacebookPage, videoFile: File): Promise<CreateAdResult> {
        return new Promise<CreateAdResult>(async (resolve, reject) => {
            try {
                const data = new FormData()
                data.append('source', videoFile)
                const result = await this.post(`/${page.id}/videos`, page, { source: data })
                resolve(result)
            } catch (error) { reject(error) }
        })
    }

    private async post(url: string, page: IFacebookPage, params: any): Promise<CreateAdResult> {
        return new Promise<CreateAdResult>(async (resolve, reject) => {
            const accessToken = await this.fetchFaceBookPageAccessToken(page.id)
            this.FB().api(url, "post", { ...params, access_token: accessToken }, (response: any) => {
                if (response && !response.error) {
                    resolve(CreateAdResult.PublishToFacebookSuccess)
                } else {
                    const msg = response && response.error ? `Failed to post content to Facebook page with error: ${response.error.message} ` : `Failed to post ad to Facebook page!`
                    reject(Error(msg)) // <----- Ends up here!!
                }
            })
        })
    }

所有这些都会在表单上导致错误消息

错误：无法将内容发布到Facebook页面，并显示错误：存在一个上传视频文件时出现问题。请重试。

我通过将视频上传到其他地方来解决了这个问题，而是将网址提供给了Facebook。

即

    async postVideo(page: IFacebookPage, videoUrl: string): Promise<CreateAdResult> {
        return new Promise<CreateAdResult>(async (resolve, reject) => {
            try {
                const result = await this.post(`/${page.id}/videos`, page, { file_url: videoUrl })
                resolve(result)
            } catch (error) { reject(error) }
        })
    }
