我正在尝试将一个对象序列化为Json,然后将其发送到Slack。我已经成功完成了此操作而不进行序列化,而是使用了“字典”和“ FormUrlEncodedContent”,然后将其发送。 但是现在,为了使事情变得更轻松,更敏捷,我只想创建一个JSon类,可以对其进行序列化,然后将其用于要发送的每个请求。
这是我的代码:
public class JsonObject
{
private string _token = "xoxp-MyToken";
[JsonProperty("token")]
public string token { get { return _token; } }
[JsonProperty("channel")]
public string channel { get; set; }
[JsonProperty("as_user")]
public bool as_user = true;
[JsonProperty("username")]
public string username { get;set; }
[JsonProperty("text")]
public string text { get; set; }
}
public class BpsHttpClient
{
private readonly HttpClient _httpClient = new HttpClient { };
public Uri UriMethod { get; set; }
public BpsHttpClient(string webhookUrl)
{
UriMethod = new Uri(webhookUrl);
}
public async Task<HttpResponseMessage> UploadFileAsync(StringContent requestContent)
{
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, UriMethod);
request.Content = requestContent;
var response = await _httpClient.SendAsync(request);
return response;
}
}
class MainArea
{
public static void Main( string[] args)
{
try
{
Task.WaitAll(SendMessage());
}
catch(Exception ass)
{
Console.WriteLine(ass);
Console.ReadKey();
}
}
private static async Task SendMessage()
{
var client = new BpsHttpClient("https://slack.com/api/chat.postMessage");
JsonObject JO = new JsonObject();
JO.channel = "DCW21NBHD";
JO.text = "This is so much fun :D !";
var Json = JsonConvert.SerializeObject(JO, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
var StringJson = new StringContent(Json, Encoding.UTF8, "application/json");
var DeSon = JsonConvert.DeserializeObject(Json);
Console.WriteLine(DeSon); //this is for me to see if my JsonObject looks correct - it does ;)
Console.ReadKey();
var Response = await client.UploadFileAsync(StringJson);
string AnswerContent = await Response.Content.ReadAsStringAsync();
Console.WriteLine(AnswerContent);
Console.ReadKey();
}
}
运行代码时,我总是得到答案:
输出:
{"ok":false,"error":"not_authed"}
尽管我认为我的JsonObject看起来不错-它里面有令牌... 有人知道为什么吗?
答案 0 :(得分:1)
所以,我想通了-我不应该将令牌放入要发送的JsonObject中。
在这种情况下(使用httpclient
的解决方案是,必须向客户端添加用于授权的标头,如下所示:
httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", "lé token");
然后它起作用。
