POST数据到Asana API在C＃ [英] POST data to Asana API in C#
问题描述
我试图用嘉尚API更新和数据添加到Asana。我该怎么做它在C＃中？
我得到的数据很好 - 样本code如下：
字符串apiKey =xxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxx;
VAR REQ = WebRequest.Create（https://app.asana.com/api/1.0/workspaces/xxxxxxxxxxxxxxx/projects）;变种AUTHINFO = apiKey +：;
变种EN codedAuthInfo = Convert.ToBase64String（Encoding.Default.GetBytes（AUTHINFO））;
req.Headers.Add（授权，基本+ EN codedAuthInfo）;
VAR响应=新的StreamReader（req.GetResponse（）GetResponseStream（）。）ReadToEnd的（）。
但我不知道如何发布数据。
他们的文档中的所有例子是使用Python，我有没有经验。
我所接触的体位，但还没有收到回音。
这是我到目前为止所。我得到的最后一行一个400错误
VAR URL =https://app.asana.com/api/1.0/workspaces/xxxxxxxxxxxxxxxxxxx/tasks;
JSON字符串=
\\数据\\：{+
\\工作空间\\：nnnnnnnnnnnnnnnn，+
\\名称\\：\\测试\\，+
\\注意事项\\：\\测试API POST \\+
};字节[]字节= Encoding.UTF8.GetBytes（JSON）;
VAR REQ = WebRequest.Create（URL）为HttpWebRequest的;req.Method =POST;
req.ContentLength = bytes.Length;
req.ContentType =应用/ JSON;变种requestStream = req.GetRequestStream（）;
requestStream.Write（字节，0，bytes.Length）;变种响应= req.GetResponse（）; //错误
这是我用专门与嘉尚API进行交互。带连接code参数函数将键值对的列表，并把它们转换成以下形式的字符串键=值和放大器;键=值。
在code的发送数据部分是不是我的，但我不记得在那里我从知道了。
我刚开始开发在C＃中的API包装，所以这是很轻的测试。它可能不是那样强劲，因为它可以，但我知道一个事实，即它的工作不够好创建体位新的工作空间。
私人字符串连接codeParameters（ICollection的＆LT; KeyValuePair＆LT;字符串，字符串＆GT;＆GT;参数）
{
字符串RET =;
的foreach（KeyValuePair＆LT;字符串，字符串＆gt;对在参数）
{
保留+ =的String.Format（{0} = {1}＆安培;，pair.Key，pair.Value）;
}
RET = ret.TrimEnd（'和;'）; 返回RET;
} 公共字符串的GetResponse（字符串URI，ICollection的＆LT; KeyValuePair＆LT;字符串，字符串＆GT;＆GT;的参数，RequestMethods方法= RequestMethods.POST）
{
返回的GetResponse（URI，恩codeParameters（参数），法）;
} 公共字符串的GetResponse（URI字符串，字符串数据=，RequestMethods方法= RequestMethods.GET）
{
System.Diagnostics.Trace.WriteLine（URI）; //创建请求
HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（URI）;
要求preAuthenticate = TRUE。
request.Method = method.ToString（）ToUpper的（）。
request.ContentType =应用/的X WWW的形式urlen codeD; // 登录
串AUTHINFO = API_KEY +：+; //空密码
AUTHINFO = Convert.ToBase64String（Encoding.Default.GetBytes（AUTHINFO））;
request.Headers [授权] =基本+ AUTHINFO; //发送数据
如果（数据！=）
{
字节[] = paramBytes Encoding.ASCII.GetBytes（数据）;
request.ContentLength = paramBytes.Length;
流reqStream = request.GetRequestStream（）;
reqStream.Write（paramBytes，0，paramBytes.Length）;
reqStream.Close（）;
} //获取响应
尝试
{
HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）;
返回新的StreamReader（response.GetResponseStream（））为ReadToEnd（）。
}
赶上（引发WebException前）
{
HttpWebResponse响应=（（HttpWebResponse）ex.Response）;
抛出新的异常（URI +引起了+（INT）response.Status code +错误。\\ n+ response.StatusDescription）;
}
}
I am trying to use the Asana API to update and add data to Asana. How do I do it in C#?
I am getting data fine - sample code below:
string apiKey = "xxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxx";
var req = WebRequest.Create("https://app.asana.com/api/1.0/workspaces/xxxxxxxxxxxxxxx/projects");
var authInfo = apiKey + ":";
var encodedAuthInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
req.Headers.Add("Authorization", "Basic " + encodedAuthInfo);
var response = new StreamReader(req.GetResponse().GetResponseStream()).ReadToEnd();
But I don't know how to POST data.
All the examples in their documentation is using Python which I have no experience with.
I have contacted Asana but have yet to hear back. This is what I have so far. I get a 400 error on the last line
var url = "https://app.asana.com/api/1.0/workspaces/xxxxxxxxxxxxxxxxxxx/tasks";
string json =
"\"data\": { " +
"\"workspace\": nnnnnnnnnnnnnnnn," +
"\"name\": \"test\"," +
"\"notes\": \"testing API POST\"" +
"}";
byte[] bytes = Encoding.UTF8.GetBytes(json);
var req = WebRequest.Create(url) as HttpWebRequest;
req.Method = "POST";
req.ContentLength = bytes.Length;
req.ContentType = "application/json";
var requestStream = req.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
var response = req.GetResponse(); //error
This is what I use specifically to interact with the Asana API. The encode parameters function takes a list of key value pairs and converts them into a string of the form "key=value&key=value".
The send data portion of the code is not mine, but I can't remember where I got it from.
I just started developing an API wrapper in C#, so this is very lightly tested. It may not be as robust as it could be, but I know for a fact that it does work well enough to create a new workspace in Asana.
private string EncodeParameters(ICollection<KeyValuePair<string, string>> parameters)
{
string ret = "";
foreach (KeyValuePair<string, string> pair in parameters)
{
ret += string.Format("{0}={1}&", pair.Key, pair.Value);
}
ret = ret.TrimEnd('&');
return ret;
}
public string GetResponse(string uri, ICollection<KeyValuePair<string, string>> parameters, RequestMethods method = RequestMethods.POST)
{
return GetResponse(uri, EncodeParameters(parameters), method);
}
public string GetResponse(string uri, string data = "", RequestMethods method = RequestMethods.GET)
{
System.Diagnostics.Trace.WriteLine(uri);
// create request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.PreAuthenticate = true;
request.Method = method.ToString().ToUpper();
request.ContentType = "application/x-www-form-urlencoded";
// log in
string authInfo = API_KEY + ":" + ""; // blank password
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
request.Headers["Authorization"] = "Basic " + authInfo;
// send data
if (data != "")
{
byte[] paramBytes = Encoding.ASCII.GetBytes(data);
request.ContentLength = paramBytes.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(paramBytes, 0, paramBytes.Length);
reqStream.Close();
}
// get response
try
{
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
return new StreamReader(response.GetResponseStream()).ReadToEnd();
}
catch (WebException ex)
{
HttpWebResponse response = ((HttpWebResponse)ex.Response);
throw new Exception(uri + " caused a " + (int)response.StatusCode + " error.\n" + response.StatusDescription);
}
}
这篇关于POST数据到Asana API在C＃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
