python - GCP Compute Engine Python API 和实例模板不起作用？

问题描述

每次我尝试在 python Compute Engine API 中使用实例模板时，它都会错误地输出 URL。

例如：使用 PyCharm 和 Python 3.9

compute = googleapiclient.discovery.build('compute', 'v1')

host_project = 'testproject123'
host_zone = 'us-central1-a'

vm_name = host_project+'-api-fetch'
instance_template = 'projects/testproject123/global/instanceTemplates/testproject123-api-1'

compute.instances().insert(project=host_project, zone=host_zone, sourceInstanceTemplate=instance_template).execute()

哪个返回

Error

  File "<input>", line 1, in <module>

Details: "[{'message': "Required field 'resource' not specified", 'domain': 'global', 'reason': 'required'}]">

知道为什么它不断将“/”转换为 %2 吗？我假设这是导致问题的原因，但我似乎无法追溯或找到简单的修复方法。

解决方案

显然，即使在https://googleapis.github.io/google-api-python-client/docs/dyn/compute_v1.instances.html#insert中正文是可选的，仍然需要带有名称的正文。添加它完全解决了这个问题。

%2F 一直作为 URL 编码的斜线正常工作。
