【解决方案1】：

替换您网址中的空格。它会起作用的。

$url = str_replace(" ", '%20', $url);

【解决方案2】：

对 url 值进行编码

试试这个

$url="http://lp.hm.com/hmprod?set=key[source],value[/model/2013/2AE%200165378%20025%2037%202916.jpg]&set=key[rotate ],value[]&set=key[width],value[]&set=key[height],value[]&set=key[x],value[]&set=key[y],value[]&set=key[type ],value[STILL_LIFE_FRONT]&hmver=0&call=url[file:/product/large]";

$image=get_fcontent($url);

print_r($image);

     $ch=curl_init();
     curl_setopt( $ch, CURLOPT_URL, $url );
     curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
     curl_setopt( $ch, CURLOPT_BINARYTRANSFER, true);
     $content = curl_exec( $ch );
 $response = curl_getinfo( $ch );
 curl_close ( $ch );
     echo "<pre>";
     print_r( $response);
    echo "<pre>";
