functiongraph创建函数

华为云搜索functiongraph然后创建函数

选择事件函数，函数运行环境选择python3.9，名称自己命名

创建完成后效果如图

这里为了避免出现明文密码，把iam用户、密码配置到环境变量中，用户可根据具体需要配置，下面为一种实现方式，index.py脚本内容如下：

import requests

import json

def handler (event, context):

# 获取token的url

url = "https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens"

payload = json.dumps({

"auth": {

"identity": {

"methods": [

"password"

],

"password": {

"user": {

"name": context.getUserData('name'),

"password": context.getUserData('password'),

"domain": {

"name": context.getUserData('domain')

}

}

}

},

"scope": {

"project": {

"name": "cn-north-4"

}

}

}

})

headers = {

'Content-Type': 'application/json'

}

res = json.dumps({

"status":"allow",

"context":{

"token":requests.request("POST", url, headers=headers, data=payload).headers.get("X-Subject-Token")

}

})

return {

"statusCode": 200,

"body": res,

"headers": {

"Content-Type": "application/json"

}

}
