在这个坑上,经历了两次,所以我不得不写篇文章记录一下。起先是因为我只定义了一个 schema:
KeySchema: - AttributeName: id KeyType: HASH
后来,变成了两个:
KeySchema: - AttributeName: id KeyType: HASH - AttributeName: token KeyType: RANGE
结果在对应的查询参数的 Key 里,漏掉了这部分的内容:
Key: { id: body.id },
导致了:
{ ValidationException: The provided key element does not match the schema at Request.extractError (/var/runtime/node_modules/aws-sdk/lib/protocol/json.js:48:27) at Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:105:20) at Request.emit (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:77:10) at Request.emit (/var/runtime/node_modules/aws-sdk/lib/request.js:683:14) at Request.transition (/var/runtime/node_modules/aws-sdk/lib/request.js:22:10) at AcceptorStateMachine.runTo (/var/runtime/node_modules/aws-sdk/lib/state_machine.js:14:12) at /var/runtime/node_modules/aws-sdk/lib/state_machine.js:26:10 at Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:38:9) at Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:685:12) at Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:115:18) message: 'The provided key element does not match the schema', code: 'ValidationException', time: 2019-02-26T12:31:25.507Z, requestId: 'POTAMPSSPFSOIU78QM637HK7BNVV4KQNSO5AEMVJF66Q9ASUAAJG', statusCode: 400, retryable: false, retryDelay: 44.331159666822884 } null END RequestId: 782c2eb3-629e-43e0-b63c-c66678c5590b
下次,记得,加上,加上:
Key: { id: body.id, token: body.token // 缺少了这部分的内容 },
以上就是本文的全部内容,希望本文的内容对大家的学习或者工作能带来一定的帮助,也希望大家多多支持 码农网
