OSS签名Header实现Demo（PHP）

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 详细信息 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; ?>

错误消息sales area is not assigned for the header product

When I try to download customer material info record from ERP, I meet with this error message in tcode SMW01: The error message is raised due to the fact that in CRM, the corresponding sales organization for this product is not found. However, since this product itself is downloaded from ERP, you could NOT add any distribution chain to it manually. Go back to ERP and check table MVKE, we can find the sales organization 0001 and channel 01 is assigned to this product correctly. This indicates that the sales area for this material has not been downloaded to CRM successfully.So go to CRM, check Sales organization mapping in organization model, and found there is no entry configured for 0001-01.Add the missing entry in tcode PPOMA_CRM after that perform a request download once again, this time you should find in SMW01 that the sales area has successfully been downloaded. Now go back to WebUI, both two assignment block now display correct data from ERP: 本文来自云栖社区合作伙伴“汪子熙”，了解相关信息可以关注微信公众号"汪子熙"。
