提问者：

Hello Everyone;

I am having a php file that gets the contents from a URL, i am getting the failure message

Collapse | Copy CodeWarning: file_get_contents(http://xxxxxx): failed to open stream: HTTP request failed! in xxxx.php on line xx

i tried so many online solutions but its still not working. here is the code

Collapse | Copy Code $cryptpass = rawurlencode(crypt($pc['pcpassword']));

$url = "http://" . $pc['pcname']."/Reports/ReportList.php?&username={$pc['pcusername']}&cryptpass=$cryptpass&noredir=1";

$parsed_list = read_general_list($url, false);

Collapse | Copy Codefunction read_general_list($url, $make_assoc = false)

{

$compressed_data = file_get_contents($url);

}

$compressed_data is always null and it throws an error:

Warning: file_get_contents(http://xxxxxx): failed to open stream: HTTP request failed! in xxxx.php on line xx

Any suggestions please?

I am sorry, i never updated this question completely. May be if some one is still looking for an answer.

This has worked for me. This is the equivalent function for File_get_contents, but can handle large amount of data. I found this solution online.

Collapse | Copy Code function file_get_contents_curl($url) {

$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set curl to return the data instead of printing it to the browser.

curl_setopt($ch, CURLOPT_URL, $url);

$data = curl_exec($ch);

curl_close($ch);

return $data;

}

第二个解答：

As the error message says, the stream (URL) requested cannot be opened. There are many possible reasons for this:

1. base URL is bad. $pc['pcname']

2. username and/or password are bad

3. username/password do not have permission on the server

4. Your system cannot reach the server (firewall, PHP permissions, ...)

4. ...

I would use the following strategy to debug:

1. Dump $url and write it down.

2. Use a browser with debug tools (eg Firefox/Firebug) and try to access that URL.

3. Look at the headers returned to see what error the server reports (if any).

4. Think about why that error is returned...

Cheers,
