使用https://api.twitter.com/1.1/direct_messages.json获取特定用户的直接消息 [英] Get Direct Messages for a particular user using https://api.twitter.com/1.1/direct_messages.json

问题描述

我正在使用https://api.twitter.com/1.1/direct_messages.json来检索特定用户的邮件。

我在使用此URL时默认情况下可以收到20封邮件但是当我想使用这个API的可选参数count将输出限制为20以外时，我得到远程服务器返回错误：（401）未经授权。在这种情况下，请帮助我。

我在这里发布我的代码。

  var  oauth_token =   oauth token; 
  var  oauth_token_secret =   oauth token secret ; 
  var  oauth_consumer_key =  使用者密钥< /跨度>; 
  var  oauth_consumer_secret =  消费者密钥 ; 
 
  //   oauth实施细节 
  var  oauth_version =   1.0; 
  var  oauth_signature_method =   HMAC-SHA1 ; 
 
  //  唯一请求详情 
  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（）; 
 
  //   message api details  
  var  status =  如果有效，则通过REST API更新状态 ; 
  var  resource_url =   https：// api.twitter.com/1.1/direct_messages.json; 
  int  count =  1 ; 
 
  //  创建oauth签名 
  var  baseFormat =   oauth_consumer_key = {0}& oauth_nonce = {1}& ; oauth_signature_method = {2} + 
  & oauth_timestamp = {3}&组oauth_token = {4}&安培; oauth_version = {5}&安培;计数= {6}; 
  //  默认为20条消息 
  //   var baseFormat =oauth_consumer_key = {0}& oauth_nonce = {1}& oauth_signature_method = {2}+  
  //  & oauth_timestamp = {3}& oauth_token = {4}& oauth_version = {5}& ; count = {6};  
 
  var  baseString =  string  .Format（baseFormat，
 oauth_consumer_key，
 oauth_nonce，
 oauth_signature_method，
 oauth_timestamp，
 oauth_token，
 oauth_version，
 Uri.EscapeDataString （count.ToString（））
）; 
 
 baseString =  string  .Concat（  GET&，Uri.EscapeDataString（resource_url）， & ，Uri.EscapeDataString（baseString））; 
 
  var  compositeKey =  string  .Concat（Uri.EscapeDataString（oauth_consumer_secret）， 
  &，Uri.EscapeDataString（oauth_token_secret））; 
 
  string  oauth_signature; 
 使用（HMACSHA1 hasher =  new  HMACSHA1（ASCIIEncoding.ASCII.GetBytes（compositeKey））） 
 {
 oauth_signature = Convert.ToBase64String（
 hasher.ComputeHash（ASCIIEncoding.ASCII.GetBytes（baseString）））; 
} 
 
  //  创建请求标题 
  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）
）; 
 
  var  postBody =   count = + Uri.EscapeDataString（count.ToString（））; 
 resource_url + =  ？ + postBody; 
  //  默认为20条消息 
  //   var postBody =count =+ Uri.EscapeDataString（count.ToString（））;  
  //   resource_url + =？ + postBody;  
 HttpWebRequest request =（HttpWebRequest）WebRequest.Create（resource_url）; 
 request.Headers.Add（ 授权，authHeader）; 
 request.Method =   GET; 
 request.ContentType =   application / json; charset = utf-8; 
 
 WebResponse response = request.GetResponse（）; 
  string  responseData =  new  StreamReader（response.GetResponseStream（））。ReadToEnd（）; 

解决方案

大家好，最后我找到了解决我自己问题的方法。

只需要纠正baseFormat和baseString。



var baseFormat =count = {6}& oauth_consumer_key = {0}& oauth_nonce = {1}& oauth_signature_method = {2} +

& oauth_timestamp = {3}& oauth_token = {4}& oauth_version = {5};

 < span class =code-keyword> var  baseString =  string  .Format（baseFormat，
 oauth_consumer_key，
 oauth_nonce，
 oauth_signature_method，
 oauth_timestamp，
 oauth_token，
 oauth_version，
 Uri.EscapeDataString（count.ToString（））
）; 

计数将在所有参数之前传递。

谢谢。

我使用了这个Url但无法阅读显示

的消息远程服务器返回错误：（401）
 Plz帮助我... 

I am using https://api.twitter.com/1.1/direct_messages.json for retreiving messages for a particular user.
I am able to get 20 messages by default when using this URL but when i want to restrict the output to other than 20 using optional parameter "count" for this API I am getting "The remote server returned an error: (401) Unauthorized." error.
Kindly help me in this scenario.
I am posting my code here.

var oauth_token = "oauth token";
var oauth_token_secret = "oauth token secret";
var oauth_consumer_key = "consumer key";
var oauth_consumer_secret = "consumer secret key";

// 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();

// message api details
var status = "Updating status via REST API if this works";
var resource_url = "https://api.twitter.com/1.1/direct_messages.json";
int count = 1;

// 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}&count={6}";
//for default 20 messages
//var baseFormat = "oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
                //"&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&count={6}";

var baseString = string.Format(baseFormat,
                            oauth_consumer_key,
                            oauth_nonce,
                            oauth_signature_method,
                            oauth_timestamp,
                            oauth_token,
                            oauth_version,
                            Uri.EscapeDataString(count.ToString())
                            );

baseString = string.Concat("GET&", 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_version)
                );

var postBody = "count=" + Uri.EscapeDataString(count.ToString());
resource_url += "?" + postBody;
//for default 20 messages
//var postBody = "count=" + Uri.EscapeDataString(count.ToString());
//resource_url += "?" + postBody;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(resource_url);
request.Headers.Add("Authorization", authHeader);
request.Method = "GET";
request.ContentType = "application/json; charset=utf-8";

WebResponse response = request.GetResponse();
string responseData = new StreamReader(response.GetResponseStream()).ReadToEnd();

解决方案

Hi All, Finally I found the solution to my own problem.
Just needed to correct the baseFormat and baseString.

var baseFormat = "count={6}&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(count.ToString())
                                       );

count will be passed prior to all the parameters.
Thanks.
