通过PHP将横幅上传到youtube

Question

我是youtube API的新手 我正在尝试使用Google提供的源代码和API将横幅上传到youtube视频，并收到此错误

An client error occurred: Error calling PUT https://www.googleapis.com/upload/youtube/v3/channelBanners/insert?uploadType=resumable&upload_id=AEnB2Uopf1XKEFaoQx4Gkfu8tZizSmvAX1l4JWPJ7txZcvQYCvo8-pfJVgJU-WiIsQI4mL8pkZwdjeUoKYvLVpSMmLI6ulN1uQ: (400) Invalid Upload Request

修改

   <?php
/**
 * This sample sets a custom banner for a user's channel by:
 *
 * 1. Uploading a banner image with "youtube.channelBanners.insert" method via resumable upload
 * 2. Getting user's channel object with "youtube.channels.list" method and "mine" parameter
 * 3. Updating channel's banner external URL with "youtube.channels.update" method
