[英]Post With C# WebClient Multiple Json Object
I want to send Post Request with C# WebClient with this Json Schema : 我想使用此Json Schema通过C#WebClient发送发帖请求:
[
{
"id": "00000000-0000-0000-0000-000000000000",
"points": [
{
"timestamp": "2017-12-04T16:07:44.562Z",
"value": 0
}
]
}
]
I've tried This : 我已经试过了
public class RequestData
{
public string id {get; set; }
public points points { get; set; }
}
public class points
{
public DateTime timestamp { get; set; }
public float value { get; set; }
}
My Program : 我的程序:
Random number = new Random();
var req = new RequestData();
req.id = "0e13d9c-571c-44f4-b796-7c40c0e20a1d";
req.points = new points { timestamp = DateTime.UtcNow, value =
number.Next(100, 99999) };
JsonSerializerSettings settings = new JsonSerializerSettings();
var data = JsonConvert.SerializeObject(req);
WebClient client = new WebClient();
client.Headers.Add(HttpRequestHeader.Authorization,
AquaAtuhorization.accessToken);
client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
client.UploadString ("http://localhost:8080/api/v1/data/writeNumericValues",
data );
And I always get Http 415 (Unsupported Media Type). 而且我总是收到Http 415(不支持的媒体类型)。
How could I format my C# Object as the restApi accepeted Format. 如何将C#对象格式化为restApi支持的格式。
Look at the JSON, the square brackets [ ]
denote that something is an array. 看一下JSON,方括号
[ ]
表示某物是一个数组。 In this case both RequestData
and points
have to be an array, see the example below: 在这种情况下,
RequestData
和points
都必须是一个数组,请参见下面的示例:
public class RequestData
{
public string id { get; set; }
public List<points> points { get; set; } // I use list, could be an array
}
public class points
{
public DateTime timestamp { get; set; }
public float value { get; set; }
}
Then construct your req
object like this: 然后像这样构造您的
req
对象:
var req = new List<RequestData> // Again I use list, could be an array
{
new RequestData
{
id = "0e740d9c-571c-44f4-b796-7c40c0e20a1d",
points = new List<points> // Defined as a list, even though it has one entry
{
new points
{
timestamp = DateTime.UtcNow,
value = number.Next(100, 99999)
}
}
}
};
Then just serialize it as normal, the result will be the below: 然后只需正常序列化,结果将如下所示:
[
{
"id":"0e740d9c-571c-44f4-b796-7c40c0e20a1d",
"points":[
{
"timestamp":"2017-12-04T17:12:25.8957648Z",
"value":59522.0
}
]
}
]
Your Json class needs to be like this, see http://json2csharp.com/ or use paste as JSON from VS https://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/ 您的Json类需要是这样的,请参阅http://json2csharp.com/或使用VS https://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special中的 JSON粘贴-JSON和- XML /
public class Point
{
public DateTime timestamp { get; set; }
public int value { get; set; }
}
public class RootObject
{
public string id { get; set; }
public List<Point> points { get; set; }
}`
