When you use Alibaba Cloud CLI to call an API operation, you can enable the log output feature to display the log of the request. This helps you analyze whether the response content is correct.
For more information about how to use OSS commands to output logs, see the Use OSS commands to output logs section of this topic.
Configure the environment variable to enable the log output feature
In the CLI, you can set the environment variable DEBUG=sdk to enable the log output feature.
Example:
aliyun ecs DescribeRegionsExample output:
# omitted output > POST /?AccessKeyId=AccessKeyId&Action=DescribeRegions&Format=JSON&RegionId=cn-hangzhou&Signature=u9lPKI5Nyw0dIKV5ytJAx6aOTJ0%3D&SignatureMethod=HMAC-SHA1&SignatureNonce=29f426485b2720f6ae0575c900590e28&SignatureType=&SignatureVersion=1.0&Timestamp=2020-05-18T09%3A52%3A42Z&Version=2014-05-26 HTTP/1.1 > Host: ecs-cn-hangzhou.aliyuncs.com > Content-Type: application/x-www-form-urlencoded > x-sdk-client: golang/1.0.0 > User-Agent: AlibabaCloud (darwin; amd64) Golang/1.13.9 Core/0.0.1 Aliyun-CLI/3.0.43 > x-sdk-invoke-type: common > Accept-Encoding: identity > x-sdk-core-version: 0.0.1 > Retry Times: 0. < HTTP/1.1 200 OK < Connection: keep-alive < Access-Control-Allow-Origin: * < Content-Length: 2238 < Vary: Accept-Encoding < Access-Control-Allow-Methods: POST, GET, OPTIONS < Access-Control-Allow-Headers: X-Requested-With, X-Sequence, _aop_secret, _aop_signature < Access-Control-Max-Age: 172800 < Date: Mon, 18 May 2020 09:52:43 GMT < Content-Type: application/json;charset=utf-8 < # omitted output
