使用C＃中的API将任务发布到Asana

Question

我试图弄清楚如何在asana中向用户发布新任务，但我不断收到400错误代码。 谁能告诉我我在做什么错。

这是我到目前为止的内容：

        string apiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
        string ID = "xxxxxxxxxxxxx";
        string url = @"https://app.asana.com/api/1.0/tasks";

        Data dat = new Data();
        dat.workspace = ID;
        dat.name = "Buy eggs";
        dat.notes = "Testing";
        string json = JsonConvert.SerializeObject(dat);
        string data ="\"data\": " + json;

        byte[] bytes = Encoding.UTF8.GetBytes(data);
        var req = (HttpWebRequest)WebRequest.Create(url);
        Console.WriteLine(bytes.ToString());
        req.Method = WebRequestMethods.Http.Post; 
        req.ContentLength = bytes.Length;
        req.ContentType = "application/json";

        var authInfo = apiKey + ":";
        var encodedAuthInfo = Convert.ToBase64String(
            Encoding.Default.GetBytes(authInfo));
        req.Headers.Add("Authorization", "Basic " + encodedAuthInfo);

        req.ContentLength = bytes.Length;
        Stream reqStream = req.GetRequestStream();
        reqStream.Write(bytes, 0, bytes.Length);
        reqStream.Close();

        try
        {
            HttpWebResponse response = (HttpWebResponse)req.GetResponse();
            string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
            Console.WriteLine(res);
            Console.ReadLine();
        }
        catch (WebException ex)
        {
            HttpWebResponse response = ((HttpWebResponse)ex.Response);
            string e = url + " caused a " + (int)response.StatusCode + " error.\n" + response.StatusDescription;
            Console.WriteLine(e);
            Console.ReadLine();
        }

我放了串行转换器，我做错了吗？

Answer 1

正如第一个评论所指出的，您需要正确地序列化数据。 发布的最终正文应类似于：

{ "data": { "name": "My Example Task", ... }}

（当然，用...替换为更多字段。）

Answer 2

我研究了很长时间，发现下面的代码有用且有效。 我可以通过我的应用程序成功将Task发布到Asana。 我已经将Json序列化器用于点网。 感谢Newtonsoft.Json。

        string json = null;
        byte[] bytes = null;
        string url = "https://app.asana.com/api/1.0/tasks";
        HttpWebRequest req = default(HttpWebRequest);
        Stream reqStream = default(Stream);
        string authInfo = null;
        Task TaskData = new Task();

        try
        {
            authInfo = apiKey + Convert.ToString(":");

            TaskData.workspace = WorkspaceId;
            TaskData.name = TaskName;
            TaskData.notes = TaskNotes;

            json = JsonConvert.SerializeObject(TaskData);
            json = json.Insert((json.Length - 1), ",\"projects\":[" + ProjectId + "]");
            json = Convert.ToString("{ \"data\":") + json + "}";

            bytes = Encoding.UTF8.GetBytes(json);

            req = (HttpWebRequest)WebRequest.Create(url);
            req.Method = WebRequestMethods.Http.Post;
            req.ContentType = "application/json";
            req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)));
            req.ContentLength = bytes.Length;

            reqStream = req.GetRequestStream();
            reqStream.Write(bytes, 0, bytes.Length);
            reqStream.Close();


            HttpWebResponse response = (HttpWebResponse)req.GetResponse();
            string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
            Console.WriteLine(res);
            Console.ReadLine();

            string finalString = res.Remove(0, 8);
            finalString = finalString.Remove((finalString.Length - 1));
            AsanaObjectId newtask = JsonConvert.DeserializeObject<AsanaObjectId>(finalString);

            return newtask;

        }
        catch (WebException ex)
        {
            HttpWebResponse response = (HttpWebResponse)ex.Response;
            string resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
            MessageBox.Show(resp);
            System.Environment.Exit(0);
        }
