PHP: 6 GET and POST request sending methods, 6 get

In the i94web blog, I tried two socialization methods, Changyan and Duoshuo. The comment box was later abandoned because it was unsafe.

Whether it is speaking freely or talking more, I need to grab the number of comments on articles remotely and then store them in the local database. For Duodao, the request format is as follows:

<span>// 获取评论次数,参数是文章ID</span><span>
<span>function</span> getCommCount($postid)
{
    $jsondata = file_get_contents(<span>"http://api.duoshuo.com/threads/counts.json?short_name=i94web&threads=$postid"</span>);
    <span>// 设置true返回数组,不设置或者是false则返回对象</span>
    $resjson= json_decode($jsondata,<span>true</span>);
    <span>return</span> $resjson[<span>'response'</span>][$postid][<span>'comments'</span>];
}</span>

For remote requests, there are many methods. Today, LZ has collected six types for your reference.

1. Use file_get_contents to get the content in get mode:

<span><?php
$url=<span>'http://www.ido321.com/'</span>;
$html = file_get_contents($url);
<span>echo</span> $html;
?></span>

2. Use fopen to open the url and use get method to obtain

<span>$fp = fopen($url, <span>'r'</span>);
stream_get_meta_data($fp);
<span>while</span>(!feof($fp)) {
$result .= fgets($fp, 1024);
}
<span>echo</span> <span>"url body: $result"</span>;
fclose($fp);</span>

3. Use file_get_contents to get the content in post mode:

<span>$data = <span>array</span> (<span>'foo'</span> => <span>'bar'</span>);
$data = http_build_query($data);
 
$opts = <span>array</span> (
<span>'http'</span> => <span>array</span> (
<span>'method'</span> => <span>'POST'</span>,
<span>'header'</span>=> <span>"Content-type: application/x-www-form-urlencodedrn"</span> .
<span>'Content-Length: '</span> . strlen($data) . <span>'rn'</span>,
<span>'content'</span> => $data
)
);
 
$context = stream_context_create($opts);
$html = file_get_contents(<span>'http://localhost/e/admin/test.html'</span>, <span>false</span>, $context);
 
<span>echo</span> $html;</span>

4. Use the fsockopen function to open the url and obtain the complete data in get mode, including header and body. fsockopen requires the allow_url_fopen option in PHP.ini to be turned on

<span>function</span><span> get_url ($url,$cookie=<span>false</span>)
{
$url = parse_url($url);
$query = $url[path].<span>'?'</span>.$url[query];
<span>echo</span> <span>'Query:'</span>.$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
<span>if</span> (!$fp) {
<span>return</span> <span>false</span>;
} <span>else</span> {
$request = <span>'GET $query HTTP/1.1rn'</span>;
$request .= <span>'Host: $url[host]rn'</span>;
$request .= <span>'Connection: Closern'</span>;
<span>if</span>($cookie) $request.=<span>'Cookie:  $cookien'</span>;
$request.=<span>'rn'</span>;
fwrite($fp,$request);
<span>while</span>(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
<span>return</span> $result;
}
}
<span>//获取url的html部分,去掉header</span>
<span>function</span> GetUrlHTML($url,$cookie=<span>false</span>)
{
$rowdata = get_url($url,$cookie);
<span>if</span>($rowdata)
{
$body= stristr($rowdata,<span>'rnrn'</span>);
$body=substr($body,4,strlen($body));
<span>return</span> $body;
}
 
<span>return</span> <span>false</span>;
}</span>

5. Use the fsockopen function to open the url and obtain the complete data in POST mode, including header and body

<span>function</span><span> HTTP_Post($URL,$data,$cookie, $referrer=<span>''</span>)
{
 
<span>// parsing the given URL</span>
$URL_Info=parse_url($URL);
 
<span>// Building referrer</span>
<span>if</span>($referrer==<span>''</span>) <span>// if not given use this script as referrer</span>
$referrer=<span>'111'</span>;
 
<span>// making string from $data</span>
<span>foreach</span>($data <span>as</span> $key=>$value)
$values[]=<span>'$key='</span>.urlencode($value);
$data_string=implode(<span>'&'</span>,$values);
 
<span>// Find out which port is needed &ndash; if not given use standard (=80)</span>
<span>if</span>(!<span>isset</span>($URL_Info[<span>'port'</span>]))
$URL_Info[<span>'port'</span>]=80;
 
<span>// building POST-request:</span>
$request.=<span>"POST "</span>.$URL_Info[<span>'path'</span>].<span>" HTTP/1.1n"</span>;
$request.=<span>"Host: "</span>.$URL_Info[<span>'host'</span>].<span>"n"</span>;
$request.=<span>"Referer: $referern"</span>;
$request.=<span>"Content-type: application/x-www-form-urlencodedn"</span>;
$request.=<span>'Content-length: '</span>.strlen($data_string).<span>"n"</span>;
$request.=<span>'Connection: closen'</span>;
 
$request.=<span>'Cookie:  $cookien'</span>;
 
$request.=<span>'n'</span>;
$request.=$data_string.<span>'n'</span>;
 
$fp = fsockopen($URL_Info[<span>'host'</span>],$URL_Info[<span>'port'</span>]);
fputs($fp, $request);
<span>while</span>(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
 
<span>return</span> $result;
}</span>

6. Use the curl library. Before using the curl library, you may need to check whether the curl extension has been turned on in php.ini

<span>$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, &lsquo;http:<span>//www.ido321.com/');</span>
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
 
<span>echo</span> $file_contents;</span>
