我的设置包含以谷歌云功能为后台的谷歌端点。
Google端点是用以下swagger v2 yaml定义的：
swagger: "2.0"

(a lot of type definitions)
这与POST端点一起工作，没有任何问题。
问题出在GET REST端点上，路径变量没有正确传递到后端。
如https://cloud.google.com/endpoints/docs/openapi/openapi-extensions我试着在上面的swaggerapi中添加x-google-backend参数。(path_translation: APPEND_PATH_TO_ADDRESS(。
然而，这并不奏效。我收到一个未经授权的错误(403(，因为端点前端没有命中云功能。
目前，我使用了一个丑陋的解决方案，没有path_translation参数，该参数将谷歌端点路径变量转换为云函数后端中同名的查询参数。即在后端调用url/documents?document_id=xyz。
(我试图实现的是通过后端url/documents/{document_id}的调用(
有人知道如何正确配置基于路径的参数，以便将其正确传递到云功能后端吗？
提前谢谢。
谨致问候，Sebastian
TL；博士：我认为你的403错误不是正确的错误。它应该是一个404，但由于端点是未知的，我想403是有答案的。
Cloud Endpoint对此行为感到沮丧。对于path_translation: APPEND_PATH_TO_ADDRESS，您认为您的最终被叫地址将是/documents/{document_id}，但否。完整的openAPI路径附加到您的后端地址，在您的情况下为：/documents/api/documents/{document_id}
这就是端点不存在的原因，您应该有一个404(而不是403(。

注意：我在这个话题上与谷歌团队有联系，在更新这个行为之前需要一段时间
