The user profile pictures on the company's website are stored on its own server, which is inconvenient to manage. The new profile pictures are uploaded to Qiniu for convenient management and unified data, the leader said that he would migrate all the pictures on the local server to Qiniu.

1. sort out ideas

First, determine whether the user's avatar is in Qiniu. if it does not exist, capture the Qiniu locally and then perform batch capturing.

2. Qiniu determines whether the image exists

1/** 2 * check whether Qiniu url exists 3 * @ param string $ url 4 */5 function url_exists ($ url) {6 require_once (COMMON_PATH. "qiniu/rs. php "); 7 require_once (COMMON_PATH. "qiniu/http. php "); 8 $ parts = parse_url ($ url); 9 $ bucket; // bucket 10 $ key = substr ($ parts ['path'], 1 ); // Qiniu file name 11 // key 12 $ accessKey; 13 $ secretKey; 14 Qiniu_SetKeys ($ accessKey, $ secretKey); 15 $ client = new Qiniu_MacHttpClient (null ); 16 list ($ ret, $ err) = Qiniu _ RS_Stat ($ client, $ bucket, $ key); // view the information of a single file 17 if ($ err! = Null) {18 return false; 19} else {20 return true; 21} 22}

3. move a single file to Qiniu

1/** 2 * move a single avatar to Qiniu 3 * @ param string $ remotePath physical address of the remote file on the server 4 * @ param string $ qiniuPath Qiniu file address 5*/6 function oneFetch ($ remotePath, $ qiniuPath) {7 if (! $ This-> url_exists ($ qiniuPath) & file_exists ($ remotePath) {8 require_once (COMMON_PATH. "qiniu/rs. php "); 9 require_once (COMMON_PATH. "qiniu/http. php "); 10 require_once (COMMON_PATH. "qiniu/conf. php "); 11 12 $ client = new Qiniu_MacHttpClient (NULL ); 13/* $ accessUrl remote file access address 14 * $ bucket 15 * $ key is stored in Qiniu_RS_Fetch ($ client, $ accessUrl, $ bucket, $ key); 18 19 if ($ ret! = NULL) 20 {21 $ errlog = 'fail. log'; // write error log 22 file_put_contents ($ errlog, "{$ key} \ n", FILE_APPEND); 23} 24 else25 {26 var_dump ($ ret ); 27} 28} else {29 var_dump ('existing Avatar '); 30} 31 32}

4. batch capture

Function t () {header ("Content-type: text/html; charset = utf-8"); set_time_limit (0 ); $ start = intval ($ _ GET ['num']); // start position $ str = ''; /* query records from the database */$ link = mysql_connect ("localhost", "root", "root") or die ("error "); $ db_selected = mysql_select_db ("test", $ link); mysql_query ("set names UTF8"); $ limit = 10; // number of queries each time $ SQL = "SELECT * FROM test order by id desc limit {$ start}, {$ limit}"; $ result = mysql_quer Y ($ SQL) or die (mysql_error (); if (mysql_num_rows ($ result) {while ($ row = mysql_fetch_assoc ($ result )) {oneFetch ($ row ['remotepath'], $ row ['qiniupath']);} $ start + = 10; $ url = "/t? Num = {$ start} "; $ str = 'updated '. $ start .'
'; $ Str. = 'script location. href = "'. $ url. '"; script'; // update $ limit, jump to prevent the script from responding} else {echo 'terminal';} echo $ str; ob_flush (); flush (); sleep (2); unset ($ SQL, $ result, $ row );}
