如何使用C＃和HttpRequestMessage在Trello中设置自定义字段？

如何解决如何使用C＃和HttpRequestMessage在Trello中设置自定义字段？

我可以使用以下代码请求委员会的卡和自定义字段：

---

  string qString = @"https://api.trello.com/1/boards/{boardId}/cards?customFieldItems=true&key={myKey}&token={myToken}";
  using(var request = new HttpRequestMessage(new HttpMethod("GET"),qString))
  {
    var response = await httpClient.SendAsync(request);
    String JsonString = await response.Content.ReadAsStringAsync();

它返回有关卡片的信息，包括以下有关我的自定义字段项目的信息：

   {
    "id": "5f5432b72678573fd5e#####","value": {
       "text": "AAA"
     },"idCustomField": "5d24ae4cfe7cb10d611#####","idModel": "5f542e224c5d2c2679d#####","modelType": "card"
   }

---

现在我正尝试使用以下代码设置值：

    using(var httpClient = new HttpClient())
    {
       using(var request = new HttpRequestMessage(new HttpMethod("PUT"),@"https://api.trello.com/1/cards/" + myCardId + "/" + myCustomFieldId + "/item?" + "key={myKey}&token={myToken}" + "{value: { text: \"New Value\"}}"))
       {
            // i don't know how to set the header content so i commented it out
            //request.Headers.Add("content-type","application/json");
            var response = await httpClient.SendAsync(request);
            String JsonString = await response.Content.ReadAsStringAsync();

---

但是它回来并说它不能放入...

谢谢， DF

解决方法

感谢您的帮助。

我能够使用该网站将Curl转换为C＃来解决我的问题：

https://curl.olsh.me/

private async void button4_Click(object sender,EventArgs e)
{
   using(var httpClient = new HttpClient())
   {
       String query = @"https://api.trello.com/1/card/" + myCardId + "/customField/" + myCardsCustomFieldItems_IdCustomField + "/item";
     using(var request = new HttpRequestMessage(new HttpMethod("PUT"),query))
     {
        request.Content = new StringContent("{  \"value\": { \"text\": \"Hello,world!\" },\"key\": \"########\",\"token\": \"#######\" }");
        request.Content.Headers.ContentType = System.Net.Http.Headers.MediaTypeHeaderValue.Parse("application/json");

        var response = await httpClient.SendAsync(request);
        String JsonString = await response.Content.ReadAsStringAsync();

        this.textBox4.Text = query;
        this.richTextBox4.Text = JsonString;
      } 
    }
  }
