在Python中使用yaml渲染(多行字符串)

下面是我的Python函数，我用它来呈现带有任何变量的yaml模板. 直到我把多行字符串传递给示例文件，它才能正常工作.

def render_template(template_path, context):
    """
    Render Jinja2 template using the provided context.
    """
    with open(template_path, 'r') as template_file:
        template = Template(template_file.read())
        return template.render(context)

下面是我调用上述函数的位置

        if centralized_data is not None:
            print("centralized_data is not None")

            rendered_template = render_template(输入_template_path, context)
            sample_data = yaml.safe_load(rendered_template)

            # Ensure both sample_data and centralized_data are dictionaries
            if isinstance(sample_data, dict) and isinstance(centralized_data, dict):
                final_data = merge_data(sample_data, centralized_data)
            else:
                print("Error: Either sample_data or centralized_data is not a dictionary")
                # Handle the error condition appropriately
                final_data = {}
        else:
            print("centralized_data is None, using sample_data directly")
            with open(输入_template_path, 'r') as template_file:
                sample_data = yaml.safe_load(template_file)
            final_data = sample_data

我认为问题发生在 sample_data = yaml.safe_load(rendered_template)个

这是我的多字符串go 投掷，看起来像这样

输入

deployment:
  annotations:
    proxy.istio.io/config: |
      concurrency: 1
      concurr222ency: 1
      concurrenc33y: 1
      f: 3

和输出

deployment:
  annotations:
    proxy.istio.io/config: 'concurrency: 1

      concurr222ency: 1

      concurrenc33y: 1

      f: 3

      '

我也试过这样的东西，但没有帮助

proxy.istio.io/config: |>
proxy.istio.io/config: >-
