WordPress 百度搜索主动推送插件，亲测有效并且附录代码

一个 WordPress 百度搜索主动推送插件的实现，该插件可以帮助网站自动将新发布的内容推送到百度搜索，加快收录速度，同时支持手动推送历史文章。

• 插件功能说明
• 这个百度搜索主动推送插件具有以下核心功能：
• 自动推送：当新文章发布时，自动将文章 URL 推送到百度搜索，无需人工干预
• 手动推送：支持三种推送方式、推送所有未推送过的文章、推送最近 10 篇文章、手动输入自定义 URL 进行推送
• 推送日志：记录所有推送记录，包括成功 / 失败状态、时间和响应信息，方便追踪推送效果

百度 API 集成：与百度搜索资源平台的主动推送 API 对接，确保推送合规有效
使用方法

• 将插件文件上传到 WordPress 的wp-content/plugins/目录
• 在 WordPress 后台激活插件
• 进入 “设置 > 百度主动推送” 页面
• 输入从百度搜索资源平台获取的 API Token
• 选择是否启用自动推送功能
• 可根据需要进行手动推送操作

注意事项

• 需要先在百度搜索资源平台验证网站所有权并获取 API Token
• 百度对每日推送数量有配额限制，插件会显示剩余配额
• 推送成功不代表一定会被收录，仅表示百度已接收该链接

这个插件可以帮助 WordPress 网站更高效地将内容提交给百度搜索，有助于提高网站内容的收录速度和搜索引擎可见性。
