CSV 到 JSON 轉換組合集屬於同一鍵

Question

我正在嘗試從 csv 文件生成一個 json 請求表。 REST Web 服務需要此請求表。

示例輸入文件：

Id,LineNo,Amt,ReceivedDt,FromDt,ToDate
123545,1,1000.00,2019-02-01T00:00:00,2019-02-01T00:00:00,2019-02-01T00:00:00
123545,2,200.00,2019-02-01T00:00:00,2019-02-01T00:00:00,2019-02-01T00:00:00
123546,1,200.00,2019-02-01T00:00:00,2019-02-01T00:00:00,2019-02-01T00:00:00

文件中有更多記錄遵循上述結構。 一個 Id 可以有多個 Line No，並且所有這些記錄都應該在一個集合中。

所需格式：

{
    "consumerData": {
        "clientCode": "CLINIC", 
        "instance": "P", 
        "userId": ""
    }, 
    "gfsauthdata": [
        {
            "ToDate": "2019-02-01T00:00:00", 
            "ReceivedDt": "2019-02-01T00:00:00", 
            "Id": "123545", 
            "LineNo": "1", 
            "Amt": "1000.00", 
            "FromDt": "2019-02-01T00:00:00"
        }, 
        {
            "ToDate": "2019-02-01T00:00:00", 
            "ReceivedDt": "2019-02-01T00:00:00", 
            "Id": "123545", 
            "LineNo": "2", 
            "Amt": "200.00", 
            "FromDt": "2019-02-01T00:00:00"
        }
    ]
},
{
    "consumerData": {
        "clientCode": "CLINIC", 
        "instance": "P", 
        "userId": ""
    }, 
    "gfsauthdata": 
        {
            "ToDate": "2019-02-01T00:00:00", 
            "ReceivedDt": "2019-02-01T00:00:00", 
            "Id": "123546", 
            "LineNo": "1", 
            "Amt": "200.00", 
            "FromDt": "2019-02-01T00:00:00"
        }
}

我無法將不同的記錄分開。 請提出一些將其分開的方法。 我正在使用下面的代碼，它將 csv 傳輸到 json，但所有記錄都是單組的。

代碼 ：

import json,csv

with open('Test.csv') as f:
    inputfile = csv.DictReader(f)
    output = []
    for row in inputfile :
        #j = json.dumps(row, indent=4)
        output.append(row)

        data = {
            'consumerData': {
                        'clientCode': 'CLINIC',
                        'instance': 'P',
                        'userId': ''
                    },
            'gfsauthdata': output
           }

print(json.dumps(data, indent=4))

您正在考慮錯誤的數據結構。 你應該像這樣使用字典：

data[userid] = { 
        "type": "CLINIC", 
        "instance": "P",
        "gfsauthdata": [
        {
            "ToDate": "2019-02-01T00:00:00", 
            "ReceivedDt": "2019-02-01T00:00:00", 
            "Id": "123545", 
            "LineNo": "1", 
            "Amt": "1000.00", 
            "FromDt": "2019-02-01T00:00:00"
        }, 
        {
            "ToDate": "2019-02-01T00:00:00", 
            "ReceivedDt": "2019-02-01T00:00:00", 
            "Id": "123545", 
            "LineNo": "2", 
            "Amt": "200.00", 
            "FromDt": "2019-02-01T00:00:00"
        }
    ]}
}
