api - 使用 Powershell 发推文

Question

我正在尝试使用 PowerShell 发推文，但我无法让它完全正常工作。 我可以发 1 或 2 条推文，是的，我在每条推文之间等待几分钟，我不会重复之前的消息。

然后它突然停止工作，我的 GetRequestStream 函数挂起，我不确定发生了什么，任何人都可以阐明这个问题吗？

提前致谢!

[Reflection.Assembly]::LoadWithPartialName("System.Net")  

$status = [System.Uri]::EscapeDataString("tweet tweet");  
$oauth_consumer_key = "<key";  
$oauth_consumer_secret = "<secret>";  
$oauth_token = "<token>";  
$oauth_token_secret = "<secret>";  
$oauth_nonce = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes([System.DateTime]::Now.Ticks.ToString()));  
$ts = [System.DateTime]::UtcNow - [System.DateTime]::ParseExact("01/01/1970", "dd/MM/yyyy", $null).ToUniversalTime();  


$oauth_timestamp = [System.Convert]::ToInt64($ts.TotalSeconds).ToString();

$hmacsha1 = new-object System.Security.Cryptography.HMACSHA1;  
$hmacsha1.Key = [System.Text.Encoding]::ASCII.GetBytes($signature_key);  
$oauth_signature = [System.Convert]::ToBase64String($hmacsha1.ComputeHash([System.Text.Encoding]::ASCII.GetBytes($signature)));  

$oauth_authorization = 'OAuth ';  
$oauth_authorization += 'oauth_consumer_key="' + [System.Uri]::EscapeDataString($oauth_consumer_key) + '",';  
$oauth_authorization += 'oauth_nonce="' + [System.Uri]::EscapeDataString($oauth_nonce) + '",';

$request.Method = "POST";  
$request.Headers.Add("Authorization", $oauth_authorization);  
$request.ContentType = "application/x-www-form-urlencoded";  
$body = $request.GetRequestStream();  
$body.write($post_body, 0, $post_body.length);  
$body.flush();  
$body.close();  
$response = $request.GetResponse();  
 $response.Close()

这是我最终超时时得到的完整错误序列:

您要关闭响应流吗？默认情况下，它们是保持事件连接，因此如果您打开其中的许多连接，您可能会因为两个并发 session 而被阻止。尝试使用:

$response.Close()
