概述

OSS的集成上传和下载提供了SDK可以直接使用，但实际使用中一些用户受限环境或者设备限制需要使用api方式来实现上传和下载，本文以PutObject接口为例，提供了PHP实现的demo。
注：建议优先使用OSS提供SDK，本文提供的只是签名实现上传demo，实际使用中需要结合业务来进行改动代码

PutObject实现Demo（测试环境php5.6.30）:

<?php function curlput($url,$data,$method='PUT',$bucket,$object,$accesskey ,$accesskeySecret){ $time = gmdate ("D, d M Y H:i:s T"); $str = "PUT\n\n"."application/json\n".$time."\n/".$bucket."/".$object; //echo($str); $signature = base64_encode(hash_hmac("sha1", $str, $accesskeySecret, true)); //echo($time); //echo($signature); $ch = curl_init(); //初始化CURL句柄 curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method); //设置请求方式 $headers = array( "Date:".$time, 'Content-Type:application/json', "Authorization:OSS ".$accesskey.":".$signature ); curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);//设置HTTP头信息 curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//设置提交的字符串 $document = curl_exec($ch);//执行预定义的CURL if(!curl_errno($ch)){ $info = curl_getinfo($ch); echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url']; } else { echo 'Curl error: ' . curl_error($ch); } curl_close($ch); return $document; } $accesskey ='xxx'; $accesskeySecret ='xxx'; $bucket = 'bucketname'; $object = 'mytest/2.txt'; $url = 'http://bucketname.oss-cn-hangzhou.aliyuncs.com/mytest/2.txt'; $data = "{wewwe:wewee}"; $return = curlput($url, $data, 'PUT',$bucket,$object,$accesskey,$accesskeySecret); var_dump($return); exit; ?>
