python - python脚本中的ListRecommendationsRequest构造函数错误

问题描述

我正在尝试使用 python3.7 脚本准备 VM Resizing Recommendations Report 我的代码如下：

导入日期时间

import logging
from google.cloud import bigquery
from google.cloud import recommender
from google.cloud.exceptions import NotFound
from googleapiclient import discovery

def main(event, context):
 client = recommender.RecommenderClient()
 recommender_type = "google.compute.instance.MachineTypeRecommender"
 projects=list_projects() #This gives list of projects
 # I hard-code the zones below:
 zones = ["us-east1-b","us-east1-c","us-east1-d","us-east4-c","us-east4-b","us-east4-a"
        ,"us-central1-c","us-central1-a","us-central1-f","us-central1-b"
        ,"us-west1-b","us-west1-c","us-west1-a"]

 for zone in zones:
            parent = client.recommender_path("my-project", zone, recommender_type)
            for element in client.list_recommendations(parent): #In this line I am getting this error and these are logs

****Parent****   projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender
Traceback (most recent call last):
  File "main.py", line 187, in main

    request = recommender_service.ListRecommendationsRequest(request)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/proto/message.py", line 441, in __init__
    raise TypeError(
TypeError: Invalid constructor input for ListRecommendationsRequest: 'projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender'

During handling of the above exception, another exception occurred:

projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender是传递给 list_recommendations 函数的参数。我不确定构造函数有什么问题，因为我得到这个：ListRecommendationsRequest 的构造函数输入无效

我是这个 google api 的新手。有人可以帮忙吗？谢谢。

解决方案

我已经检查了我的代码，调用该方法时似乎是语法错误。根据库文档，第一个参数应该是请求对象或None并且父参数必须按名称传递。如下更改行我没有错误：

client.list_recommendations(parent=parent)
