    Problem description

    The AccessKeyId field in the request is missing.

    Causes

    You initialized a request that used an Amazon S3-compatible signature. However, the request did not include the AWSAccessKeyId field.

    Examples

    The following code provides an example of a request that uses an S3-compatible signature and does not include the AWSAccessKeyId field. 

    GET /test.txt?Expires=1141889120Signature=vjbyPxybdZaNmGa%2ByT272YEAiv**** HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

    Solutions

    If you want to initiate a request that uses an Amazon S3-compatible signature, you must include the following fields into the request: AWSAccessKeyId, Expires, and Signature. The following code provides an example of a complete request:

    GET /test.txt?AWSAccessKeyId=nz2p****&Expires=1141889120&Signature=vjbyPxybdZaNmGa%2ByT272YEAiv**** HTTP/1.0
Date: Tue, 20 Dec 2022 08:48:18 GMT
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
x-oss-s3-compat: true

    We recommend that you use Amazon S3 SDKs to initiate the request. For more information, see Use Amazon S3 SDKs to access OSS.
