javascript - 如何使用 node js googleapis 客户端上传和更新 youtube channel 横幅

Question

我正在编写一个上传和更新 youtube channel 横幅的应用程序。我正在使用 node.js 和 google api 客户端。在官方的 api 文档中没有关于 node.js 如何发送图像内容的示例，也没有关于回调签名的信息这是我的代码:

var google = require('googleapis');
var OAuth2 = google.auth.OAuth2;
var oauth2Client = new OAuth2();
var youtube = google.youtube({ version: 'v3' });

//Setting the credentials
oauth2Client.setCredentials({
    access_token: 'STORED_IN_DATABASE',
    refresh_token: 'STORED_IN_DATABASE',        
});

//Send the request
youtube.channelBanners.insert({ 
    auth: oauth2Client,
    //image_content
}, callback);

调用insert方法后，还要调用channels.update方法，node.js上也没有例子

来自 Channel banners insert ，你必须打电话:

• channelBanners.insert，并从响应中获取url字段
• channels.update 与之前检索到的 URL

您还需要用于 channels.update 请求的 channel ID。还要注意 from Channel update :

If you are submitting an update request, and your request does not specify a value for a property that already has a value, the property's existing value will be deleted.

因此您可能需要调用 channels.list 来更新包含 brandingSettings 部分的 channel 对象

API 调用 google-api-nodejs-client :

• channelBanners.insert

  youtube.channelBanners.insert({
      media: {
          mimeType: "image/jpeg",
          body: fs.createReadStream('banner.jpeg')
      }
  }, function(err, uploadResponse, response) {
  
  });
  

可用的mimeType有image/jpeg, image/png, application/octet-stream

• channels.list

  youtube.channels.list({
      part: "brandingSettings",
      mine: true
  }, function(err, channelListRsp, response) {
  
  });
  

• channels.update

  channelListRsp.items[0].brandingSettings.image.bannerExternalUrl = uploadResponse.url;
  
  youtube.channels.update({
      part: "brandingSettings",
      resource: channelListRsp.items[0]
  }, function(err, channelUpdateResp, response) {
  
  });
  

为当前用户 channel 列表中找到的第一个 channel 更新横幅的完整示例:

youtube = google.youtube({
    version: 'v3',
    auth: oauth2Client
});

youtube.channelBanners.insert({
    media: {
        mimeType: "image/jpeg",
        body: fs.createReadStream('banner.jpeg')
    }
}, function(err, uploadResponse, response) {

    if (err)
        console.error("channelBanners.insert error : ", err);
    if (response)
        console.log('channelBanners.insert : ' + response.statusCode);

    if (uploadResponse && uploadResponse.url) {

        console.log("setting channel brandingSettings : " + uploadResponse.url);

        youtube.channels.list({
            part: "brandingSettings",
            mine: true
        }, function(err, channelListRsp, response) {

            if (err)
                console.error('channels.list error : ', err);
            if (response)
                console.log('channels.list : ' + response.statusCode);

            if (channelListRsp && channelListRsp.items && channelListRsp.items.length > 0) {

                console.log("updating banner for channel id : " + channelListRsp.items[0].id);

                // set the url
                channelListRsp.items[0].brandingSettings.image.bannerExternalUrl = uploadResponse.url;

                //update channel brandingSettings
                youtube.channels.update({
                    part: "brandingSettings",
                    resource: channelListRsp.items[0]
                }, function(err, channelUpdateResp, response) {

                    if (err)
                        console.error('channels.update error : ', err);
                    if (response)
                        console.log('channels.update : ' + response.statusCode);
                    if (channelUpdateResp)
                        console.log(channelUpdateResp);
                });
            }
        });
    }
});
