* 请先运行一次软件，然后会生成一个config.json的文件，然后在文件中填入必要的参数

不能每天自动发送吗？
可以放到服务器上设定每天早上7点自动运行一次，嫌麻烦的也可以微信打开这个链接wxpusher.zjiecode.com/wxuser/?type=2&id=6574#/follow关注主题后，每天早上7点群发早报 LeonSmith153 发表于 2023-11-16 14:33
楼主，想问下我这边运行`go run main.go`后总是提示“请在config.json中填入必要的配置！”
我使用了如下 ...
这个要编译后再运行，不然每次生成的config.json都会在不同的临时目录
```
{
"appToken": "",
"topicIds": [
0,
1,
2
],
"uids": [
"0",
"1",
"2"
]
}
``` 可以，用用试试看 技术贴，学习了。 可以，挺有意思的！支持！ 111111111 技术贴，学习了，支持楼主:lol 每日新闻确实是一个获取知识的途径 学习一下逻辑 技术贴，学习了感谢楼主教学 新手学习!
