我一直在使用curl和PHP。今天我一直在尝试获取http://www.webhostingstuff.com/category/Best-Hosting.html,我不断获得http代码0,这对我来说是新的。
我设置了标题
$s->headers = array(
"User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0.1) Gecko/20100101 Firefox/4.0.1",
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Accept-Language: en-gb,en;q=0.5",
"Accept-Encoding: gzip, deflate",
"Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7",
"Keep-Alive: 115",
"Connection: keep-alive",
"Referer: https://google.com"
);
我有一个cookie文件(当脚本加载时没有任何内容)
这是卷曲功能
function fetch($url, $username='', $data='', $proxy=''){
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
if(isset($proxy)) {
curl_setopt($ch,CURLOPT_TIMEOUT,30);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, 'proxyadmin:parola');
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT,true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0.1) Gecko/20100101 Firefox/4.0.1");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
if(!empty($username)) {
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie/{$username}.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie/{$username}.txt");
}
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
if (is_array($data) && count($data)>0) {
curl_setopt($ch, CURLOPT_POST, true);
$params = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
}
if (is_array($this->headers) && count($this->headers)>0){
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
}
$this->result = curl_exec($ch);
$curl_info = curl_getinfo($ch);
$header_size = $curl_info["header_size"];
$this->headers = substr($this->result, 0, $header_size);
$this->http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$this->error = curl_error($ch);
curl_close($ch);
}
我还试图通过SSH从不同的服务器执行(如果它被IP阻止)
[brian@ip-184-168-22-244 ~]$ curl -url http://www.webhostingstuff.com/addcomments/5ite.html Enter host password for user 'rl': curl: (7) couldn't connect to host [brian@ip-184-168-22-244 ~]$
我该如何解决这个问题?

你的命令
curl -url http://www.webhostingstuff.com/addcomments/5ite.html
应该是:
curl --ur http://www.webhostingstuff.com/addcomments/5ite.html
cURL认为您正在指定-u选项,该选项用于指定用户名,因此您会收到错误消息。您需要指定--url(两个破折号)。
希望至少有助于调试。

状态码0表示在返回任何输出之前关闭(正常)连接。
我想我首先想弄清楚你是否可以连接到机器上。如果您可以访问远程计算机,则可能有助于调试。
答案 2 :(得分:3)
就我而言,由于连接超时,正在返回http代码0。添加
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
我能够摆脱错误

也许这是一些内部服务器错误?现在它起作用了:
> GET /category/Best-Hosting.html HTTP/1.1
> User-Agent: HTTP_Request2/0.5.2 (http://pear.php.net/package/http_request2) PHP/5.2.12
> Host: www.webhostingstuff.com
> Accept: */*
> Accept-Encoding: deflate, gzip
>
< HTTP/1.1 200 OK
< date: Sun, 31 Jul 2011 10:57:43 GMT

< last-modified: Sun, 31 Jul 2011 10:55:00 GMT
< content-encoding: gzip
< vary: Accept-Encoding
< transfer-encoding: chunked
< content-type: text/html
我使用HTTP_Request2 pear包作为curl包装器,代码:
$url = 'http://www.webhostingstuff.com/category/Best-Hosting.html';
$request = new HTTP_Request2 (
$url,
HTTP_Request2::METHOD_GET,
array (
'adapter' => new HTTP_Request2_Adapter_Curl(),
'ssl_verify_peer' => false,
)
);
$request->attach(new HTTP_Request2_Observer_Log('log.txt'));
$result = $request->send();

0代码表示curl找不到您要查找的服务器。 “yahoo.com/whatever”将返回404,而“yahoo.comwhatever”将返回0。
答案 5 :(得分:0)
昨天我遇到了类似的问题。我在这个问题上花了2个小时。我在RHEL系统上。卷曲代码在块下面进行身份验证:
if($httpCode == 200) {
$_SESSION["username"] = $username;
$_SESSION["password"] = $password;
return array(true, "Login successful. Please wait while you are redirected to home page.");
}else if($httpCode == 401){
return array(false, "Login failure. Incorrect username / password");
}
此代码用于身份验证。在实验室环境中它返回200,但在生产时它返回0。
然后我制作了一个类似的脚本(使用curl),然后从php test3.php
这样的命令行运行。此次运行产生了200
状态代码。
然后出于好奇,我决定通过运行此命令暂时关闭SELinux
:
setenforce 0
猜猜这是有效的。然后,您可以通过运行setsebool httpd_can_network_connect on
