净Twitter的OAuth的如何执行成功的GET请求 [英] .Net Twitter OAuth how to perform a successful GET request

问题描述

下面这个教程，我能够执行成功后到Twitter API并更新我的状态。

<一个href="http://www.$c$cproject.com/Articles/247336/Twitter-OAuth-authentication-using-Net?fid=1649027&df=90&mpp=25&noise=3&prof=False&sort=Position&view=Quick&spc=Relaxed&fr=26#xx0xx" rel="nofollow">http://www.$c$cproject.com/Articles/247336/Twitter-OAuth-authentication-using-Net?fid=1649027&df=90&mpp=25&noise=3&prof=False&sort=Position&view=Quick&spc=Relaxed&fr=26#xx0xx

但我无法处理一个成功的GET请求。我想修改POST请求来实现这一点，但不断收到无效协议的错误在我的网页例外。

以下是工作code，将发布状态更新。 https://dev.twitter.com/docs/api/1.1/post /状态/更新

我试图修改code到亲热下面的GET请求 https://dev.twitter.com/docs/api/1.1/get /状态/ user_timeline

我知道我需要补充的是，GET请求要求screen_name或用户ID参数。 我需要改变基本格式和字符串包含正确的参数和要求。 我尝试添加了网名的headerformat与认证报头。 （不知道如果需要的话） 如果我理解正确get请求不需要身体。

我修补了这个code了，而试图将其转换没有成功GET请求。

它是如何做？

解决方案

您不必通过头通过画面名称参数。将它作为查询字符串的请求URL：

  https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=Starcraft2foru
 

更新：这是完全未经测试，所以我很抱歉，如果存在一些误区。 （我用 DotNetOpenAuth 在我的应用程序，所以我不担心这些OAuth的详细信息。）以下的大多数是从你的问题你code，只是做一些更改。另外，一定要使用 Twitter的API控制台测试所有您的来电，看看它们是否有效。

  //请求详细信息
变种oauth_version =1.0;
VAR oauth_signature_method =HMAC-SHA1;
变种oauth_nonce = Convert.ToBase64String（新ASCIIEncoding（）的GetBytes（DateTime.Now.Ticks.ToString（））。）;
变种时间跨度= DateTime.UtcNow  - 新日期时间（1970年，1，1，0，0，0，0，DateTimeKind.Utc）;
VAR oauth_timestamp = Convert.ToInt64（timeSpan.TotalSeconds）的ToString（）;
VAR resource_url =htt​​ps://api.twitter.com/1.1/statuses/user_timeline.json

//加密的OAuth签名
变种baseFormat =oauth_consumer_key = {0}＆安培; oauth_nonce = {1}＆安培; oauth_signature_method = {2}+
    与＆amp; oauth_timestamp = {3}＆安培; oauth_token = {4}＆安培; oauth_version = {5};

VAR basestring的=的String.Format（baseFormat，
                            oauth_consumer_key，
                            oauth_nonce，
                            oauth_signature_method，
                            oauth_timestamp，
                            oauth_token，
                            oauth_version
                            ）;

basestring的= string.Concat（GET和放大器;，Uri.EscapeDataString（resource_url）
             与＆amp;，Uri.EscapeDataString（basestring的））;

//加密数据

VAR compositeKey = string.Concat（Uri.EscapeDataString（oauth_consumer_secret）
            与＆amp;，Uri.EscapeDataString（oauth_token_secret））;

串oauth_signature;
使用（HMACSHA1散列器=新HMACSHA1（ASCIIEncoding.ASCII.GetBytes（compositeKey）））
{
    oauth_signature = Convert.ToBase64String（hasher.ComputeHash（ASCIIEncoding.ASCII.GetBytes（basestring的）））;
}

//完成身份认证报头

变种headerFormat =OAuth的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 =的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）
                ）;

//关闭EX preCT 100继续头
ServicePointManager.Expect100Continue = FALSE;

HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（resource_url）;
request.Headers.Add（授权，authHeader）;
request.Method =GET;

WebResponse的响应= request.GetResponse（）;
串responseData;

使用（StreamReader的读者=新的StreamReader（response.GetResponseStream（）））
{
    responseData = reader.ReadToEnd（）;
}

返回responseData; //或做任何你想做的响应
 

Following this tutorial I was able to perform a successful post to the Twitter API and update my status.

http://www.codeproject.com/Articles/247336/Twitter-OAuth-authentication-using-Net?fid=1649027&df=90&mpp=25&noise=3&prof=False&sort=Position&view=Quick&spc=Relaxed&fr=26#xx0xx

However I am having trouble processing a successful GET request. I am trying to modify the Post request to accomplish this but keep getting "Invalid Protocol" errors on my web exception.

The following is the working code that will Post a status update. https://dev.twitter.com/docs/api/1.1/post/statuses/update

I tried to modify the code to perfrom the following GET request https://dev.twitter.com/docs/api/1.1/get/statuses/user_timeline

I know I need to add the screen_name or user id parameter that the get request requires. I need to change the base format and string to contain the correct parameters and request. I tried adding the screen name to the headerformat and auth header. (not sure if needed) And If I understand correctly get requests don't require a body.

I tinkered with this code for a while trying to convert it to a get request without success.

How is it done?

解决方案

You do not have to pass the screen name parameter through the header. Pass it as a query string to the request URL:

https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=Starcraft2foru

UPDATE: This is completely untested so I apologize if there are some errors. (I use DotNetOpenAuth in my application so I don't have to worry about these OAuth details.) Most of the following is your code from your question, just made a few changes to it. Also, be sure to use the Twitter API Console to test all your calls to see if they are valid.

//Request details
var oauth_version = "1.0";
var oauth_signature_method = "HMAC-SHA1";
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://api.twitter.com/1.1/statuses/user_timeline.json

//encrypted 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
                            );

baseString = string.Concat("GET&", Uri.EscapeDataString(resource_url),
             "&", Uri.EscapeDataString(baseString));

//Encrypt data

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)));
}

//Finish Authentification 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)
                );

//Disable exprect 100 continue header
ServicePointManager.Expect100Continue = false;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
request.Headers.Add("Authorization", authHeader);
request.Method = "GET";

WebResponse response = request.GetResponse();
string responseData;

using(StreamReader reader = new StreamReader(response.GetResponseStream()))
{
    responseData = reader.ReadToEnd();
}

return responseData; // Or do whatever you want with the response
