使用C＃获取401从Twitter流API [英] Getting 401 from Twitter Stream API using C#
本文介绍了使用C＃获取401从Twitter流API的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我得到了一些code Twitter的更新和搜索从<一个API href=\"http://www.$c$cproject.com/Articles/247336/Twitter-OAuth-authentication-using-Net?msg=4587417#xx4587417xx\"相对=nofollow> $ C $的CProject 这工作就好了。
不过，我得到401当我试图将其转换为流API： HTTPS ：//stream.twitter.com/1/statuses/filter.json 。我将AP preciate任何帮助。请参见下面code：
使用系统;
使用System.Collections.Generic;
使用System.Linq的;
使用System.Text;

HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（resource_url）;
request.Headers.Add（授权，authHeader）;
request.Method =POST;
request.ContentType =应用/的X WWW的形式urlen codeD;
要求preAuthenticate = TRUE。
request.AllowWriteStreamBuffering = TRUE; WebResponse的响应= request.GetResponse（）;
字符串responseData =新的StreamReader（response.GetResponseStream（））为ReadToEnd（）。 }
}
解决方案
尝试包括你的查询字符串即basestring：
VAR baseFormat =oauth_consumer_key = {0}＆安培; oauth_nonce = {1}＆安培; oauth_signature_method = {2}+
＆放大器; oauth_timestamp = {3}＆安培;组oauth_token = {4}＆安培; oauth_version = {5}＆安培;轨道= {6};
无功即basestring =的String.Format（baseFormat，
oauth_consumer_key，
oauth_nonce，
oauth_signature_method，
oauth_timestamp，
组oauth_token，
oauth_version，
Uri.EscapeDataString（valueToTrack）
）;
...
VAR postBody =轨道=奥巴马;
https://dev.twitter.com/docs/auth/creating-signature 说：
5.带百分比code参数字符串，并将其追加到输出字符串。
I got some code for Twitter update and search api from CodeProject which worked just fine.
However, i get 401 when i tried to convert it for the stream api: "https://stream.twitter.com/1/statuses/filter.json". I will appreciate any help. See code below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Security.Cryptography;
using System.IO;
public class OAuthRead
{
public static void Authenticate()
{
// oauth application keys
var oauth_consumer_key = "****";
var oauth_consumer_secret = "*****";
var oauth_token = "******";
var oauth_token_secret = "******";
// oauth implementation details
var oauth_version = "1.0";
var oauth_signature_method = "HMAC-SHA1";
// unique request details
var oauth_nonce = Convert.ToBase64String(
new ASCIIEncoding().GetBytes(DateTime.Now.Ticks.ToString()));
var timeSpan = DateTime.UtcNow
- new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
var oauth_timestamp = Convert.ToInt64(timeSpan.TotalSeconds).ToString();
//var resource_url = "https://stream.twitter.com/1/statuses/filter.json?track=obama&include_entities=1&language=en";
//var resource_url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
var resource_url = "https://stream.twitter.com/1.1/statuses/filter.json";
//var screen_name = "femitfash";
// create oauth signature
var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
"&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}";
var baseString = string.Format(baseFormat,
oauth_consumer_key,
oauth_nonce,
oauth_signature_method,
oauth_timestamp,
oauth_token,
oauth_version
//,Uri.EscapeDataString(screen_name)
);
baseString = string.Concat("POST&", Uri.EscapeDataString(resource_url), "&", Uri.EscapeDataString(baseString));
var compositeKey = string.Concat(Uri.EscapeDataString(oauth_consumer_secret),
"&", Uri.EscapeDataString(oauth_token_secret));
string oauth_signature;
using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey)))
{
oauth_signature = Convert.ToBase64String(
hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString)));
}
// create the request header
var headerFormat = "OAuth oauth_nonce=\"{0}\", oauth_signature_method=\"{1}\", " +
"oauth_timestamp=\"{2}\", oauth_consumer_key=\"{3}\", " +
"oauth_token=\"{4}\", oauth_signature=\"{5}\", " +
"oauth_version=\"{6}\"";
var authHeader = string.Format(headerFormat,
Uri.EscapeDataString(oauth_nonce),
Uri.EscapeDataString(oauth_signature_method),
Uri.EscapeDataString(oauth_timestamp),
Uri.EscapeDataString(oauth_consumer_key),
Uri.EscapeDataString(oauth_token),
Uri.EscapeDataString(oauth_signature),
Uri.EscapeDataString(oauth_version)
);
// make the request
ServicePointManager.Expect100Continue = false;
var postBody = "track=obama&include_entities=1&language=en"; // "screen_name=" + Uri.EscapeDataString(screen_name);//
resource_url += "?" + postBody;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
request.Headers.Add("Authorization", authHeader);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.PreAuthenticate = true;
request.AllowWriteStreamBuffering = true;
WebResponse response = request.GetResponse();
string responseData = new StreamReader(response.GetResponseStream()).ReadToEnd();
}
}
解决方案
try include your query string to baseString:
var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
"&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&track={6}";
var baseString = string.Format(baseFormat,
oauth_consumer_key,
oauth_nonce,
oauth_signature_method,
oauth_timestamp,
oauth_token,
oauth_version,
Uri.EscapeDataString(valueToTrack)
);
....
var postBody = "track=obama";
https://dev.twitter.com/docs/auth/creating-signature says: 5. Percent encode the parameter string and append it to the output string.
