检出商品详情中的图片并替换url

原有的批量导入是按照系统本身的功能导入商品，现在需要用接口将图片上传图片服务器

所以需要将批量导入的商品图片取出来，上传后替换掉原来的url

（1）检出详情中的图片，用文件名做key

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

private function search_content_img($content){         //匹配img标签src属性中?之前部分的正则         $img_pattern = "|<img[^>]+src=['\" ]?([^ '\"?]+)['\" >]|U";         preg_match_all($img_pattern, $content, $img_out, PREG_SET_ORDER);         $img_change = array();         foreach ($img_out as $k => $value) {             $tmp= $value[1];             $file_info = pathinfo($tmp);             $key = $file_info['filename'];             $img_change[$key] = array(                 'old_img'=> $tmp,                 'new_img'=> '',                 );         }         return $img_change;     }

（2）找出图片的实际路径，调用上传接口，将生成的url，保存到对应的key

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

private function change_url($arr,$goods_img_path,$url,$goods_img_url){           $count = 0;         $sum = count($arr);         foreach ($arr as $key => $value) {             $old_img = $value['old_img'];             $filename = "";             if(!(strpos($old_img,'http://')===false)){                 $filename = str_ireplace($goods_img_url,$goods_img_path,$old_img);             }else{                 $filename = $goods_img_path.'/'.$old_img;             }             if(!file_exists($filename)){                      continue;             }               $rs = $this->sendPicToServer($url, $filename);             if($rs){                 $data = json_decode($rs,true);                 if($data['error']==0){                     $arr[$key]['new_img'] = $data['data']['pic_src'];                     $count++;                 }             }         }         return $arr;     }

（3）用curl上传图片

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

function sendPicToServer($url, $filename,$use="avatar",$bizid="102"){         $finfo    = finfo_open(FILEINFO_MIME);         $mimetype = finfo_file($finfo, $filename);         $type = explode(";",$mimetype);         finfo_close($finfo);         $s = curl_init();         curl_setopt($s, CURLOPT_POST,true);         $picture = null;           if (PHP_VERSION<5.5) {             $picture = "@$filename;type=$mimetype";         }else{             $picture = curl_file_create(@$filename,$type[0]);         }         $post_data = array (             "picture" =>$picture,         );         curl_setopt($s, CURLOPT_POSTFIELDS, $post_data);         curl_setopt($s, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);         curl_setopt($s, CURLOPT_URL,            $url);         curl_setopt($s, CURLOPT_TIMEOUT,        1000);         curl_setopt($s, CURLOPT_RETURNTRANSFER, 1);         $body = curl_exec($s);         if($body===false){             $msg = 'Curl error no: ' . curl_errno($s).",";             $msg.= 'Curl error info: ' . curl_error($s).".";             $this->write_log($msg,1);         }         curl_close($s);         return $body;     }

（4）替换详情里的图片

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

private function replace_content_img($content,$arr){         $error = 1;         if($arr){             foreach ($arr as $key => $value) {                 $content = str_replace($value['old_img'], $value['new_img'], $content);             }         }         if(strpos($content,'/shopfw/')===FALSE){             $error = 0;         }         $rs = array(             'error'=>$error,             'content'=>$content,             );         return $rs;     }
