輸入yaml文件kind: Testingmetadata: name: test-file annotations: purpose: To test the deployed codespec: containers: - name: client image: {{.registry}}/xyz:{{.client}} env: {{ if ne .proxy "" }} - name: http_proxy value: "{{.proxy}}" {{ end -}}我想加載字典中除占位符內容之外的所有 yaml 內容。我怎樣才能實現它？我可以使用任何正則表達式來過濾占位符嗎？我嘗試使用以下代碼，它適用于沒有占位符值但在上述 yaml 中給出解析錯誤的 yaml。def __load_yaml(filename): with open(filename, 'r') as stream: try: return yaml.load(stream, Loader=yaml.FullLoader) except yaml.YAMLError as exception: raise exception def main(): data = {} data.update(__load_yaml(file)) print(data) if __name__ == '__main__': main()我也試過這個，它正在將 yaml 加載到字典中，但也給出了 FileNotFoundError。有沒有辦法將列表讀取為流？或任何建議我怎樣才能實現它？：def __load_yaml(filename):with open(filename, 'r') as stream: try: data = [] for text in stream: match = re.search(r'\{\{.*?\}\}', text) if not match and text != None: data.append(text) with open(str(data), 'r') as stream: return yaml.load(stream, Loader=yaml.FullLoader) except yaml.YAMLError as exception: raise exception

def __load_yaml(filename):
with open(filename, "r") as stream:
string = stream.read()
# Find placeholders
reg_one = re.findall(r':\{\{.*?\}\}', string)
reg_two = re.findall(r'\{\{.*?\}\}', string)
placeholders = reg_one + reg_two
# Replace placeholders
for placeholder in placeholders:
string = string.replace(placeholder, "")
try:
return yaml.load(string, Loader=yaml.FullLoader)
except yaml.YAMLError as exception:
raise exception
