Does not support fsockopen, but supports communication between ucenter and modoer in the culr environment

When the website was launched, modoer and ucenter could not communicate. I had to spend almost two days. at first, I thought that my configuration was faulty. after the platform was transplanted, I could not communicate. I modified the configuration several times, if the problem is not successful, it is suspected that the code is incorrect, the file permission is incorrect, or the function is not supported. After troubleshooting, it is found that the L1 host of HiChina does not support fsockopen, in the file uc_client/client. A problem occurs in uc_fopen in php. the code here is as follows:

The code is as follows:

Function uc_fopen ($ url, $ limit = 0, $ post = '', $ cookie ='', $ bysocket = FALSE, $ ip = '', $ timeout = 15, $ block = TRUE ){
$ Return = '';
$ Matches = parse_url ($ url );
! Isset ($ matches ['host']) & $ matches ['host'] = '';
! Isset ($ matches ['path']) & $ matches ['path'] = '';
! Isset ($ matches ['query']) & $ matches ['query'] = '';
! Isset ($ matches ['port']) & $ matches ['port'] = '';
$ Host = $ matches ['host'];
$ Path = $ matches ['path']? $ Matches ['path']. ($ matches ['query']? '? '. $ Matches ['query']: ''):'/';
$ Port =! Empty ($ matches ['port'])? $ Matches ['port']: 80;
If ($ post ){
$ Out = "POST $ path HTTP/1.0 \ r \ n ";
$ Out. = "Accept: */* \ r \ n ";
// $ Out. = "Referer: $ boardurl \ r \ n ";
$ Out. = "Accept-Language: zh-cn \ r \ n ";
$ Out. = "Content-Type: application/x-www-form-urlencoded \ r \ n ";
$ Out. = "User-Agent: $ _ SERVER [HTTP_USER_AGENT] \ r \ n ";
$ Out. = "Host: $ host \ r \ n ";
$ Out. = 'content-Length: '. strlen ($ post). "\ r \ n ";
$ Out. = "Connection: Close \ r \ n ";
$ Out. = "Cache-Control: no-cache \ r \ n ";
$ Out. = "Cookie: $ cookie \ r \ n ";
$ Out. = $ post;
} Else {
$ Out = "GET $ path HTTP/1.0 \ r \ n ";
$ Out. = "Accept: */* \ r \ n ";
// $ Out. = "Referer: $ boardurl \ r \ n ";
$ Out. = "Accept-Language: zh-cn \ r \ n ";
$ Out. = "User-Agent: $ _ SERVER [HTTP_USER_AGENT] \ r \ n ";
$ Out. = "Host: $ host \ r \ n ";
$ Out. = "Connection: Close \ r \ n ";
$ Out. = "Cookie: $ cookie \ r \ n ";
}
$ Fp = @ fsockopen ($ ip? $ Ip: $ host), $ port, $ errno, $ errstr, $ timeout );
If (! $ Fp ){
Return ''; // note $ errstr: $ errno \ r \ n
} Else {
Stream_set_blocking ($ fp, $ block );
Stream_set_timeout ($ fp, $ timeout );
@ Fwrite ($ fp, $ out );
$ Status = stream_get_meta_data ($ fp );
If (! $ Status ['timed _ out']) {
While (! Feof ($ fp )){
If ($ header = @ fgets ($ fp) & ($ header = "\ r \ n" | $ header = "\ n ")){
Break;
}
}
$ Stop = false;
While (! Feof ($ fp )&&! $ Stop ){
$ Data = fread ($ fp, ($ limit = 0 ||$ limit> 8192? 8192: $ limit ));
$ Return. = $ data;
If ($ limit ){
$ Limit-= strlen ($ data );
$ Stop = $ limit <= 0;
}
}
}
@ Fclose ($ fp );
Return $ return;
}
}

The fsockopen function cannot be used, because it can only rely on other methods. thanks to the support for curl and file_get_contents, the uc_fopen function is modified using curl;

The code is as follows:

Function uc_fopen ($ url, $ limit = 0, $ post = '', $ cookie ='', $ bysocket = FALSE, $ ip = '', $ timeout = 15, $ block = TRUE ){
$ Return = '';
$ Curl = curl_init ();
Curl_setopt ($ curl, CURLOPT_URL, $ url );
Curl_setopt ($ curl, CURLOPT_USERAGENT, $ _ SERVER ['http _ USER_AGENT ']);
If ($ post ){
Curl_setopt ($ curl, CURLOPT_POST, 1 );
Curl_setopt ($ curl, CURLOPT_POSTFIELDS, $ post );
}
If ($ cookie ){
Curl_setopt ($ curl, CURLOPT_COOKIE, $ cookie );
}
Curl_setopt ($ curl, CURLOPT_TIMEOUT, $ timeout );
Curl_setopt ($ curl, CURLOPT_HEADER, 0 );
Curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1 );
$ Return = curl_exec ($ curl );
If (curl_errno ($ curl )){
Echo'

Error:
'. Curl_error ($ curl );
}
Curl_close ($ curl );
Return $ return;
}
 
Therefore, uc_client/client under modoer. uc_cilent/client under php and uchome. php modified the uc_open function in this way. The first time curl is used, there are still a lot of information on the Internet, so there is no obstacle, but I don't know if this modification will affect other things, to be tested ....
