Question

从嵌套的json文件中提取数据并插入到sql db中。 从关键详细信息中，我想在下面获取信息并插入到sql db中；

json文件数据和键/值的示例如下

[Get("/client-sales")]
Task<ClientSaleCollectionR12n> SearchClientSales([Header("Authorization")] string authorization,
                                                         DateTime? completedAfter = null,
                                                         DateTime? completedBefore = null);

这是我用来提取数据并将其插入sql的代码段

GET /client-sales?completedAfter=2020-03-20T14:54:26.786&completedBefore=2020-03-21T15:16:33.212

从上面的代码中，我能够获得包含数据的键详细信息，但是我得到的详细信息值已显示并插入到sql中的1个大块数据中（sql列详细信息）...谢谢。

您可以使用str和/或details方法轻松解析与split()键相关的find()。一行一行，并假设:左侧的所有内容都是键，右侧的所有内容都是值。

例如：

import json

myfile = 'sample.json'

with open(myfile, 'r') as f:
   mydata = json.load(f)

for entry in mydata['response']['client_log']['data']:
    parsed_details = {}
    for line in entry['details'].split('\r\n'):
        split = line.find(': ') # find() returns -1 if no match is found
        if split != -1:
            key = line[:split]
            value = line[split+2:] # 2 = len(': ')
            parsed_details[key] = value
    entry['parsed_details'] = parsed_details

或

import json

myfile = 'sample.json'

with open(myfile, 'r') as f:
   mydata = json.load(f)

for entry in mydata['response']['client_log']['data']:
    parsed_details = {}
    for line in entry['details'].split('\r\n'):
        try:
            key, value = line.split(': ', maxsplit=1)
            parsed_details[key] = value
        except ValueError:
            # This error is only thrown when the line doesn't have ': ' in it, 
            # which means there aren't enough values to unpack. It is safe to pass.
            pass
    entry['parsed_details'] = parsed_details

dict mydata['response']['client_log']['data']的每个项目list现在具有一个parsed_details键，其值为dict，并提取了键和值对从details键中删除，如您在此输出中看到的：

我对SQL不太熟悉，因此在您更新数据库的最后一步上没有帮助。

将一个键的字符串值提取到嵌套json中的另一个键/值中，然后插入到sql db中
