Python分享消息到Twitter、Youtube、Facebook平台

概述

第三方登录平台免不了需要登录验证，比起命令行输入账号密码再填充表单，不如直接用浏览器实在

Twitter

概述

使用tweepy进行登录验证拿到access_token后，可以自由发布文字、图片。

  • 需要登录验证
  • 需要第三方库：tweepy
  • 需要建立开发者应用
  • 可以发布纯文字推、带图推及
  • 视频上传功能在当前版本tweepy(3.6.0)有bug，在github上已经被修复，但还没有发布到新版本

环境配置

开发者后台
  1. 打开https://apps.twitter.com/ 新建应用
  2. 依次输入相关信息。其中：Callback URLs必须是可访问的地址
  3. 进入应用，点开Keys and Access Tokens
  4. 得到Consumer Key和Consumer Secret

Youtube

概述

Youtube 上只能分享视频。Youtube API 使用Google开发者后台，所以需要先与Google对接。

  • 需要登录验证
  • 只能分享视频
  • 需要建立开发者应用
  • Youtube使用Google体系，需要通过google验证
  • 需要真实有效，并且通过google所有权验证的回调地址
  • 需要多个第三方库
  • 需要凭据文件

环境配置

开发者后台
  1. 打开Google API Console https://console.developers.google.com/apis
  2. 新建项目
  3. 点开菜单，依次点击API和服务→信息中心→启用API和服务
  4. 搜索YouTube Data API v3并启用
  5. 点开菜单，依次点击凭据→OAuth同意屏幕，填写相关资料并保存
  6. 打开Search Console https://www.google.com/webmasters/tools/home?hl=zh-CN
  7. 输入回调网址，点击添加属性。按照要求验证所填网址
  8. 回到Google API Console，点击网域验证→添加网域，填入刚才验证通过的网址
  9. 点击凭据→创建凭据→OAuth客户端ID，选择网页客户端，填写相关资料并保存
  10. 下载client_secret.json凭据文件

Facebook

概述

Facebook停用了public_actions权限以后，就不再支持登录后接管账户的操作了，要通过facebook分享内容只能通过额外提供的分享页面，该页面只能分享网址。不过可以通过在目标网址中添加mate标签来实现部分自定义内容。

  • 需要登录验证
  • 只能用户手动发布分享，不能自动执行
  • 只能分享链接，但可以部分自定义
  • 需要填写回调网址
  • 需要应用ID

相关链接

环境配置

开发者后台
  1. 打开 https://developers.facebook.com/apps
  2. 新建APP，填写相关资料
  3. 在左边菜单点击添加产品→facebook登录
  4. 在左边菜单点击→facebook登录→设置，输入有效 OAuth 跳转 URI和取消授权的回调地址
  5. 在左边菜单点击设置→基本，填写应用域名及其他相关资料并保存
  6. 记下应用编号app_id
运行库

Facebook分享不需要第三方库
