在 JSON 文件中提取以不同标识符开头的不同路径

Question

我有一个 json 文件，它包含不同的 API 规范，其中我对路径字段感兴趣，每个 API 都不同，我想提取这些以供我分析。但是有一些问题。

有些路径是这样开始的：

    "paths": {
      "/pipeline": {
        "404": "Not Found"
      },
      "/pipeline/{pipeline_id}": {
        "404": "Not Found"
      },
      "/pipeline/{pipeline_id}/config": {
        "404": "Not Found"
      },
      "/pipeline/{pipeline_id}/composer": {
        "404": "Not Found"
      },
      "/pipeline/{pipeline_id}/jenkinsfile": {
        "404": "Not Found"
      },
      "/pipeline/{pipeline_id}/run": {
        "404": "Not Found"
      }

 "paths": {
      "/convert": {
        "get": {
          "tags": [
            "Converter"
          ],
          "summary": "Convert a swagger definition",
          "description": "Converts the supplied payload to a 3.0 specification\nbased on a `url` parameter, which points to a older\nspecification version\n",
          "operationId": "convertByUrl",
          "parameters": [
            {
              "name": "url",
              "in": "query",
              "description": "A URL to the swagger definition",
              "required": true,
              "type": "string"
            }
          ],

而其他人是这样的：

"paths": {
      "/api/v1/pulses": {
        "404": "Not Found"
      },
      "/api/v1/pulses/{pulse-number}": {
        "404": "Not Found"
      },
      "/api/v1/jetdrops/{jetdrop-id}/records": {
        "404": "Not Found"
      },
      "/api/v1/lifeline/{object-reference}/records": {
        "404": "Not Found"
      }

我想提取它们，以便我可以对哪一个进行分类版本在它们中（如 api/v1），以及没有版本的。有什么办法可以在不获取参数的情况下提取版本，因为我不确定路径中有多少个版本。我不知道从哪里开始，所以任何帮助将不胜感激！

像这样？使用过滤器。我不得不使用 JSON.loads 因为它似乎仍然是字符串格式

1. 在 Python 对象中加载数据

   import json
   json_data = json.loads("""{
       "paths": {
           "/pipeline": {
               "404": "Not Found"
           },
           "/pipeline/{pipeline_id}": {
               "404": "Not Found"
           },
           "/pipeline/{pipeline_id}/config": {
               "404": "Not Found"
           },
           "/pipeline/{pipeline_id}/composer": {
               "404": "Not Found"
           },
           "/pipeline/{pipeline_id}/jenkinsfile": {
               "404": "Not Found"
           },
           "/pipeline/{pipeline_id}/run": {
               "404": "Not Found"
           },
           "/convert": {
               "get": {
                   "tags": [
                       "Converter"
                   ],
                   "summary": "Convert a swagger definition",
                   "description": "Converts the supplied payload to a 3.0 specification\nbased on a `url` parameter, which points to a older\nspecification version\n",
                   "operationId": "convertByUrl",
                   "parameters": [
                       {
                           "name": "url",
                           "in": "query",
                           "description": "A URL to the swagger definition",
                           "required": true,
                           "type": "string"
                       }
                   ]
               }
           },
           "/api/v1/pulses": {
               "404": "Not Found"
           },
           "/api/v1/pulses/{pulse-number}": {
               "404": "Not Found"
           },
           "/api/v1/jetdrops/{jetdrop-id}/records": {
               "404": "Not Found"
           },
           "/api/v1/lifeline/{object-reference}/records": {
               "404": "Not Found"
           }
       }
   }""")
   

   2. 提取以“/api/v1/”或“/convert”开头的所有内容：

   paths = json_data["paths"]
   start = ("/api/v1/", "/convert")
   new_paths = dict(filter(lambda item: item[0].startswith(start), paths.items()))
   print(json.dumps(new_paths, indent=4))
   

   3. 提取所有包含“/pulses”或“/jetdrops/”的内容：

   paths = json_data["paths"]
   key_words = ["/pulses", "/jetdrops/"]
   new_paths = dict(filter(lambda item: any(key_word in item[0] for key_word in key_words), paths.items()))
   print(json.dumps(new_paths, indent=4))
