description: Find out more about Swagger

我编写了以下代码来提取所有API端点（/ pets，/ pets / {petID}，...）和API类型（GET，PUT，POST等。）。
import yaml
import json
with open("swagger.yaml", 'r') as yaml_in, open("examplepets.json", "w") as json_out:
yaml_object = yaml.safe_load(yaml_in) # yaml_object will be a list or a dict - Converts the
json.dump(yaml_object, json_out, indent=2)
with open("examplepets.json", "r") as reading:
data = json.load(reading)
for path, values in data['paths'].items():
print(path.replace('{', '${')) # If required used print statement
for value in values:
print(value) # If required use print statement
我需要进一步详细说明代码，以便从swagger文件中获取以下值，键“ consumes”，“ produces”下的Values： 在“参数：”下，我需要获取键的值->“名称”，“中”，“必需”，“类型”以下键列出的键下的值应与相应的API端点API一起提取并打印方法类型 “消费：”，“产生：” “参数：”我需要获取键的值->“名称”，“中”，“必需”，“类型”
注意：我已经介绍了获取API端点和API方法类型的代码。
答案 0 :(得分：1)
尝试一下
import yaml
import json
with open("./test.yaml", 'r') as yaml_in, open("yml_test.json", "w") as json_out:
data = json.loads(json.dumps(yaml.load(yaml_in, Loader=yaml.FullLoader)))
output_dict = {}
for url in data["paths"]:
for method in data["paths"][url]:
output_dict[url + "/" + method] = {}
output_dict[url + "/" + method]["parameters"] = {}
if "consumes" in data["paths"][url][method]:
output_dict[url+"/"+method]["consumes"] = data["paths"][url][method]["consumes"]
if "produces" in data["paths"][url][method]:
output_dict[url+"/"+method]["produces"] = data["paths"][url][method]["produces"]
if data["paths"][url][method]["parameters"]:
if "in" in data["paths"][url][method]["parameters"][0]:
output_dict[url+"/"+method]["parameters"]["in"] = data["paths"][url][method]["parameters"][0]["in"]
if "name" in data["paths"][url][method]["parameters"][0]:
output_dict[url+"/"+method]["parameters"]["name"] = data["paths"][url][method]["parameters"][0]["name"]
if "required" in data["paths"][url][method]["parameters"][0]:
output_dict[url+"/"+method]["parameters"]["required"] = data["paths"][url][method]["parameters"][0]["required"]
if "type" in data["paths"][url][method]["parameters"][0]:
output_dict[url+"/"+method]["parameters"]["type"] = data["paths"][url][method]["parameters"][0]["type"]
json.dump(output_dict, json_out)
输出如下所示，并将其保存到yml_test.json文件中。
