Question

我试图制作下面的Json

{
    "retailer": "The retailer",
    "sites": [{
        "id": "1234",
        "Sitename": "Microsoft",
        "website": "www.microsoft.com"
    }],
    "Products": [{
        "Name": "Visual Studio",
        "Year": "2017"
    }]
}

网站（数组，但我使用过List）。产品（阵列，但我使用过List）

我的代码（不产生上述Json）

        Parent par = new Parent();
        List<Sites> parList = new List<Sites>();

        Sites site = new Sites();
        Software sw = new Software();
        List<Software> swList = new List<Software>();

        par.retailer = "The retailer";

        site.Id = "1234";
        site.Sitename = "Microsoft";
        site.Website = "www.microsoft.com";

        par.sites = parList;

        sw.Name = "Visual Studio";
        sw.Year = DateTime.Year;

        swList.Add(sw);

        site.Products = swList;

        parList.Add(site);

        MemoryStream stream1 = new MemoryStream();
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Parent));

        ser.WriteObject(stream1, par);

        stream1.Position = 0;
        StreamReader sr = new StreamReader(stream1);
        Console.WriteLine(op);

我需要做的是生成Json（来自数据库的数据，但是现在我已经对这些值进行了硬编码）并将其发布到第三方服务但是我不能让Json采用我的格式要求？我怎么能实现这个目标？

Answer 1

对于像这样的东西，我喜欢将json转换为类的网站，然后你就知道你正在使用什么。

对于你的例子，有点谷歌和我得到这些课程。

import boto3
import datetime
from dateutil.tz import tzlocal

idp = boto3.client("cognito-idp")
identity = boto3.client("cognito-identity")

# login into user pool
response = idp.admin_initiate_auth(AuthFlow='ADMIN_NO_SRP_AUTH', UserPoolId='us-east-1_4xnGZyQWy', AuthParameters={'USERNAME':'admin', 'PASSWORD':'Ka12345'}, ClientId='25pafveaaladb2qalfh3i7s4h9')

logins = {
    "cognito-idp.us-east-1.amazonaws.com/us-east-1_4xkGZxQWy":response["AuthenticationResult"]["IdToken"]
}

# get identity_id
get_id_response = identity.get_id(IdentityPoolId="us-east-1:bfd63186-8e01-462a-8a5b-db58d7d4af2a", Logins=logins)
identity_id = get_id_response["IdentityId"]

# get credentials
credentials = identity.get_credentials_for_identity(IdentityId=identity_id, Logins=logins)
print(credentials)
credentials["Credentials"]["Expiration"] = str(credentials["Credentials"]["Expiration"])

# get open id token
oidToken = identity.get_open_id_token(IdentityId=identity_id, Logins=logins)

output = dict()
output["identityId"] = identity_id
output["token"] = oidToken["Token"]
output["credentials"] = credentials["Credentials"]

print(output)

您现在应该能够在RootObject中设置数据并正确序列化。

Answer 2

创建像这样的类

public class Site
{
    public string id { get; set; }
    public string Sitename { get; set; }
    public string website { get; set; }
}

public class Product
{
    public string Name { get; set; }
    public string Year { get; set; }
}

public class Example
{
    public string retailer { get; set; }
    public List<Site> sites { get; set; }
    public List<Product> Products { get; set; }
}

然后将所有数据放入像这样的对象

Example par = new Example();
List<Site> parList = new List<Site>();
Site site = new Site();
Product sw = new Product();
List<Product> swList = new List<Product>();
par.retailer = "The retailer";
site.id = "1234";
site.Sitename = "Microsoft";
site.website = "www.microsoft.com";
par.sites = parList;
sw.Name = "Visual Studio";
sw.Year = DateTime.Now.Year.ToString();
swList.Add(sw);
par.Products = swList;
parList.Add(site);

然后在Newtonsoft

的帮助下序列化您的对象

string ser = JsonConvert.SerializeObject(par);
Console.WriteLine(ser);

这就是ser看起来

的方式

以正确的格式生成Json
