一、python

rasa3的模型训练的时候支持yaml格式数据进行训练，可以使用python发送yaml数据，代码如下：

trainurl = "http://localhost:8899/model/train"
f = open("request.yml",encoding = "utf-8")
data=f.read()
#print(data)
#response = requests.post(url=trainurl, data=data,headers={'Content-Type': 'application/x-yaml'})

print("response:",response)

二、postman post数据

1，headers

2，body
