wordpress发布文章自动同步到新浪微博头条文章

自从新浪微博接口调整后,本站就没有使用同步功能,前几天无意看到同步到新浪微博头条文章,于是就弄到自己站,改了点代码。同步失败不会创建文件。

感谢张戈博客提供的初始代码、无主题博客的头条代码,祭夜的代码(wp5.3版本经过测试无法同步文章图片到头条封面)

1.代码增加:同步失败在文章自定义栏目weibo_sync增加错误代码,同步成功则增加weibo_sync字段1。
2.修复部分文章发布报:param text invalid。
3.修复头条封面显示默认图片的问题。

使用微博头条文章同步首先要申请微博的头条文章高级写入接口。

接口文档地址:
https://open.weibo.com/wiki/Toutiao/api

请求URL
https://api.weibo.com/proxy/article/publish.json
提交成功返回:

{"code":100000,"msg":"","data":{"object_id":"1022:2310474468279925145779","url":"http:\/\/weibo.com\/ttarticle\/p\/show?id=2310474468279925145779","mid":4468279927839992}}

用户名或密码错误失败返回:

{"request":"/proxy/article/publish.json","error_code":"21302","error":"username or password error!"}

发布太频繁会返回110045:

{"code":110045,"msg":"\u53d1\u5e03\u5931\u8d25,\u8bf7\u7a0d\u540e\u91cd\u65b0\u53d1\u5e03","data":[]}

把14,15,16行修改成你自己的账号信息。
如果发布文章不想同步到新浪微博头条文章,手动增加weibo_sync即可。效果见:

把下面的代码放入主题文件functions.php
