返回结果

更新时间:2017-07-25 11:28:22   分享:   

调用 API 服务后返回数据采用统一格式:

  • 返回的 HTTP 状态码为 2xx,代表调用成功。
  • 返回的 HTTP 状态码为 4xx 或 5xx,代表调用失败。

调用成功返回的数据格式主要有 XML 和 JSON 两种,外部系统可以在请求时传入参数来制定返回的数据格式,默认为 XML 格式。

本文档中的返回示例为了便于用户查看,做了格式化处理,实际返回结果是没有进行换行、缩进等处理的。

成功结果

XML示例:

<?xml version="1.0" encoding="UTF-8"?> 
<!--结果的根结点-->
<接口名称+Response>
    <!--返回请求标签-->
    <RequestId>4C467B38-3910-447D-87BC-AC049166F216</RequestId>
    <!--返回结果数据-->
</接口名称+Response>

JSON示例:

{
    "RequestId": "4C467B38-3910-447D-87BC-AC049166F216",
    /* 返回结果数据 */
}

错误结果

调用接口出错后,将不会返回结果数据。调用方可根据每个接口对应的错误码以及下述 公共错误码 来定位错误原因。 当调用出错时,HTTP 请求返回一个 4xx 或 5xx 的 HTTP 状态码。返回的消息体中是具体的错误代码及错误信息。另外还包含一个全局唯一的请求 ID:RequestId 和一个您该次请求访问的站点 ID:HostId。在调用方找不到错误原因时,可以联系阿里云客服,并提供该 HostId 和 RequestId,以便我们尽快帮您解决问题。

XML示例:

<?xml version="1.0" encoding="UTF-8"?>
<Error>
   <RequestId>8906582E-6722-409A-A6C4-0E7863B733A5</RequestId>
   <HostId>ecs.aliyuncs.com</HostId>
   <Code>InvalidOwnerId</Code>
   <Message>The specified OwnerId is not valid.</Message>
</Error>

JSON示例:

{
    "RequestId": "8906582E-6722-409A-A6C4-0E7863B733A5",
    "HostId": "ecs.aliyuncs.com",
    "Code": "InvalidOwnerId",
    "Message": "The specified OwnerId is not valid."
}
