通过 REST API 调用下载特定 JSON 键值数据的 Python 代码

Question

我正在尝试用 python 编写代码，它只下载调用中的特定键值。

所以解决办法可能是

1. 下载原始数据，然后通过正则表达式删除不需要的数据或 2) 在 API 调用中应用特定进程，它只下载并附加“值”。

注意 - 不包括 access_token 的代码。

邮递员的基本代码是

url = "https://xyz-stg.csod.com/services/api/x/odata/api/views/vw_rpt_performance_comment"

payload={}
headers = {
  'Authorization': 'Bearer ' + access_token,
  'Cookie': 'ASP.NET_SessionId=hsylq0qqp; Cookie_2=value'
}

response = requests.request("GET", url, headers=headers, data=payload).json()

print(response, file=open(r"C:\Users\path\Desktop\Python script\output.json", 'w', encoding='utf-8', errors='ignore'))


while response['@odata.nextLink']:
    url = response['@odata.nextLink']
    response = requests.request("GET", url, headers=headers, data=payload).json()
    #response.extend(response)


    print(response, file=open(r"C:\Users\path\Desktop\Python script\output.json", 'a', encoding='utf-8', errors='ignore'))
    break

原始 json 输出数据

*{ "@odata.context": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment", "value": [ { "pr_comment_id": 1, "pr_comment": "Test Comment" }, { "pr_comment_id": 2, "pr_comment": "Test Comment" }, { "pr_comment_id": 3, "pr_comment": "Test Comment" } ],
"@odata.nextLink": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment?$skip=1000"
} { "@odata.context": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment", "value": [ { "pr_comment_id": 4, "pr_comment": "Test Comment" }, { "pr_comment_id": 5, "pr_comment": "Test Comment" }, { "pr_comment_id": 6, "pr_comment": "Test Comment" } ],
"@odata.nextLink": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment?$skip=2000"

当您的个人回复通过时，您可以使用extend（相对于append）创建一个值列表。然后创建你的最终字典。

这是一种实现方式的模型 - 收集所有响应，然后遍历列表。否则，您可以在每个响应进入时对其进行解析。

response1 = { "@odata.context": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment", "value": [ { "pr_comment_id": 1, "pr_comment": "Test Comment" }, { "pr_comment_id": 2, "pr_comment": "Test Comment" }, { "pr_comment_id": 3, "pr_comment": "Test Comment" } ],
"@odata.nextLink": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment?$skip=1000"
} 

response2 = { "@odata.context": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment", "value": [ { "pr_comment_id": 4, "pr_comment": "Test Comment" }, { "pr_comment_id": 5, "pr_comment": "Test Comment" }, { "pr_comment_id": 6, "pr_comment": "Test Comment" } ],
"@odata.nextLink": "https://example.com/services/api/x/odata/api/views/$metadata#vw_rpt_review_response_comment?$skip=2000"
}

value_list = []
for resp in [response1, response2]:
    # print(resp['value'])
    value_list.extend(resp['value'])

my_dict = {'value': value_list}
my_dict

输出

{'value': [{'pr_comment_id': 1, 'pr_comment': 'Test Comment'},
  {'pr_comment_id': 2, 'pr_comment': 'Test Comment'},
  {'pr_comment_id': 3, 'pr_comment': 'Test Comment'},
  {'pr_comment_id': 4, 'pr_comment': 'Test Comment'},
  {'pr_comment_id': 5, 'pr_comment': 'Test Comment'},
  {'pr_comment_id': 6, 'pr_comment': 'Test Comment'}]}
