# 七、Flask+Github触发webhoop接口

```python
[root@iZj6cbtjqbqb2cx7qdl9z5Z bugbk.com]# more app.py
#coding: utf8

# github中webhooks的secret

def encryption(data):
    key = github_secret.encode('utf-8')
    obj = hmac.new(key, msg=data, digestmod='sha1')
    return obj.hexdigest()

@app.route('/bugbk', methods=['POST'])

    github加密是将post提交的data和WebHooks的secret通过hmac的sha1加密，放到HTTP headers的
