我有一个包含 Json 格式数据的 .Json URL。
HTTPS://XXXX/fetch-transaction?fromdate=2020-10-13&toDate=2020-10-20(仅作为示例)
[
{
"orderId": 110,
"consignmentNumber": "TEST",
"itemNumbers": [
"TEST"
],
"country": "UK",
"orderType": "ORDER_HOME_DELIVERY",
"paymentTransactionId": "395611",
"priceInOre": 5900,
"paidAt": "2020-10-16 10:51:08",
"orderNumber": "7000067718",
"articleName": "SOUTH-2"
}
]
我想将数据插入到 SQL Server 表中,想知道是否可以直接使用 SQL Server 和 t-SQL,还是应该使用 VS 和 C#?
如果 C# 是首选,有人可以指导我如何实现它吗? 我已经在 Visual Studio 中创建了一个控制台应用程序(但是,使用其他东西创建命令行应用程序可能是更好的解决方案?)或引导我走向正确的方向。
您可以尝试以下代码从json txt中获取值并将其传输到sql server表。
using Newtonsoft.Json;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.IO;
using System.Linq;
class Program
{
static void Main(string[] args)
{
string json = File.ReadAllText("D:\\test1.txt");
List<Example> list = JsonConvert.DeserializeObject<List<Example>>(json);
string strcon = @"Connstr";
SqlConnection connection = new SqlConnection(strcon);
connection.Open();
string sql = "Insert into JsonData(orderId,consignmentNumber,itemNumbers,country,orderType,paymentTransactionId,priceInOre,paidAt,orderNumber,articleName) values(@orderId,@consignmentNumber,@itemNumbers,@country,@orderType,@paymentTransactionId,@priceInOre,@paidAt,@orderNumber,@articleName)";
SqlCommand command = new SqlCommand(sql, connection);
foreach (Example item in list)
{
command.Parameters.AddWithValue("@orderId", item.orderId);
command.Parameters.AddWithValue("@consignmentNumber", item.consignmentNumber);
command.Parameters.AddWithValue("@itemNumbers", item.itemNumbers.First());
command.Parameters.AddWithValue("@country", item.country);
command.Parameters.AddWithValue("@orderType", item.orderType);
command.Parameters.AddWithValue("@paidAt", item.paidAt);
command.Parameters.AddWithValue("@paymentTransactionId", item.paymentTransactionId);
command.Parameters.AddWithValue("@priceInOre", item.priceInOre);
command.Parameters.AddWithValue("@articleName", item.articleName);
command.Parameters.AddWithValue("@orderNumber", item.orderNumber);
}
command.ExecuteNonQuery();
connection.Close();
}
}
public class Example
{
public int orderId { get; set; }
public string consignmentNumber { get; set; }
public List<string> itemNumbers { get; set; }
public string country { get; set; }
public string orderType { get; set; }
public string paymentTransactionId { get; set; }
public int priceInOre { get; set; }
public string paidAt { get; set; }
public string orderNumber { get; set; }
public string articleName { get; set; }
}
最终结果:
编辑:
var json = new WebClient().DownloadString("URL");
上面的代码几乎没有变化。
