问题描述

客户端加密场景下PutObject 、InitiateMultipartUpload、UploadPart缺少请求头x-oss-meta-client-side-encryption-magic-number-hmac。

问题原因

客户端加密场景下，在进行PutObject 、InitiateMultipartUpload、UploadPart时，若请求头x-oss-meta-client-side-encryption-wrap-alg对应的值为“rsa”，则需要携带请求头x-oss-meta-client-side-encryption-magic-number-hmac。

问题示例

例如您发起了一个InitiateMultipartUpload请求：

POST /multipart.data?uploads HTTP/1.1 
Host: oss-example.oss-cn-hangzhou.aliyuncs.com 
Date: Wed, 22 Feb 2012 08:32:21 GMT 
x-oss-storage-class: Archive
Authorization: OSS qn6qrrqxo2oawuk53otfjbyc:/cluRFtRwMTZpC2hTj4F67AG****
x-oss-meta-client-side-encryption-key: val0
x-oss-meta-client-side-encryption-start: val1
x-oss-meta-client-side-encryption-cek-alg: val2
x-oss-meta-client-side-encryption-wrap-alg: rsa
x-oss-meta-client-side-encryption-data-size: val5
x-oss-meta-client-side-encryption-part-size: val6

由于请求头x-oss-meta-client-side-encryption-wrap-alg对应值为“rsa”，同时缺少请求头x-oss-meta-client-side-encryption-magic-number-hmac，请求返回失败。

解决方案

客户端加密场景下，进行PutObject 、InitiateMultipartUpload、UploadPart时，若请求头x-oss-meta-client-side-encryption-wrap-alg对应的值为“rsa”，则需要携带请求头x-oss-meta-client-side-encryption-magic-number-hmac。
