Whether talking or speaking, I need to capture the comments of the article remotely and store them in the local database. For more information, the request format is as follows:

The Code is as follows:

// Gets the number of comments. The parameter is the Article ID. Function getCommCount ($ postid) { $ Jsondata = file_get_contents ("http://api.duoshuo.com/threads/counts.json? Short_name = i94web & threads = $ postid "); // Set true to return an array. If not set or false, the object is returned. $ Resjson = json_decode ($ jsondata, true ); Return $ resjson ['response'] [$ postid] ['comments']; }

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

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

The Code is as follows:
$ Url = 'HTTP: // www.111cn.net /'; $ Html = file_get_contents ($ url ); Echo $ html; ?>

2. Open the url with fopen and get it with get

The Code is as follows:
$ Fp = fopen ($ url, 'R '); Stream_get_meta_data ($ fp ); While (! Feof ($ fp )){ $ Result. = fgets ($ fp, 1024 ); } Echo "url body: $ result "; Fclose ($ fp );

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

The Code is as follows:

$ Data = array ('foo' => 'bar '); $ Data = http_build_query ($ data ); $ Opts = array ( 'Http' => array ( 'Method' => 'post ', 'Header' => "Content-type: application/x-www-form-urlencodedrn ". 'Content-Length: '. strlen ($ data). 'rn ', 'Content' => $ data ) ); $ Context = stream_context_create ($ opts ); $ Html = file_get_contents ('HTTP: // localhost/e/admin/test.html ', false, $ context ); Echo $ html;

4. Use the fsockopen function to open the url and get the complete data, including the header and body. fsockopen must be enabled using the allow_url_fopen option in PHP. ini.

The Code is as follows:

Function get_url ($ url, $ cookie = false) { $ Url = parse_url ($ url ); $ Query = $ url [path]. '? '. $ Url [query]; Echo 'query: '. $ Query; $ Fp = fsockopen ($ url [host], $ url [port]? $ Url [port]: 80, $ errno, $ errstr, 30 ); If (! $ Fp ){ Return false; } Else { $ Request = 'get $ query HTTP/1.1rn '; $ Request. = 'host: $ url [Host] rn '; $ Request. = 'Connection: closern '; If ($ cookie) $ request. = 'cookie: $ cookien '; $ Request. = 'rn '; Fwrite ($ fp, $ request ); While (! @ Feof ($ fp )){ $ Result. = @ fgets ($ fp, 1024 ); } Fclose ($ fp ); Return $ result; } } // Obtain the html part of the url and remove the header Function GetUrlHTML ($ url, $ cookie = false) { $ Rowdata = get_url ($ url, $ cookie ); If ($ rowdata) { $ Body = stristr ($ rowdata, 'rnrn '); $ Body = substr ($ body, 4, strlen ($ body )); Return $ body; } Return false; }

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

The Code is as follows:

Function HTTP_Post ($ URL, $ data, $ cookie, $ referrer = '') { // Parsing the given URL $ URL_Info = parse_url ($ URL ); // Building referrer If ($ referrer = '') // if not given use this script as referrer $ Referrer = '000000 '; // Making string from $ data Foreach ($ data as $ key => $ value) $ Values [] = '$ key ='. urlencode ($ value ); $ Data_string = implode ('&', $ values ); // Find out which port is needed-if not given use standard (= 80) If (! Isset ($ URL_Info ['Port']) $ URL_Info ['Port'] = 80; // Building POST-request: $ Request. = "POST". $ URL_Info ['path']. "HTTP/1.1n "; $ Request. = "Host:". $ URL_Info ['host']. "n "; $ Request. = "Referer: $ referern "; $ Request. = "Content-type: application/x-www-form-urlencodedn "; $ Request. = 'content-length: '. strlen ($ data_string). "n "; $ Request. = 'Connection: closen '; $ Request. = 'cookie: $ cookien '; $ Request. = 'n '; $ Request. = $ data_string. 'n '; $ Fp = fsockopen ($ URL_Info ['host'], $ URL_Info ['Port']); Fputs ($ fp, $ request ); While (! Feof ($ fp )){ $ Result. = fgets ($ fp, 1024 ); } Fclose ($ fp ); Return $ result; }

6. before using the curl library, you may need to check whether php. ini has enabled the curl extension.

The Code is as follows:
$ Ch = curl_init (); $ Timeout = 5; Curl_setopt ($ ch, CURLOPT_URL, 'HTTP: // www.111cn.net /'); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 ); Curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, $ timeout ); $ File_contents = curl_exec ($ ch ); Curl_close ($ ch ); Echo $ file_contents;
