xml - 在哪里可以找到 Amazon 发布的 S3 XSD(XML 架构定义)？

Question

我的一个应用程序使用 REST API 与 Amazon S3 服务器交互，对服务器执行了“删除多个”操作并遇到了错误响应:

<?xml version="1.0" encoding="UTF-8"?>
<Error>
    <Code>MalformedXML</Code>
    <Message>The XML you provided was not well-formed or did not validate against our published schema</Message>
    <RequestId>6FA...D61</RequestId>
    <HostId>E5G...uhg=</HostId>
</Error>

引用Amazon documentation :

This happens when the user sends malformed xml (xml that doesn't conform to the published xsd) for the configuration. The error message is, "The XML you provided was not well-formed or did not validate against our published schema."

我的应用程序的某些删除键包含可能会导致问题的编码字符。因此，我希望查看 Amazon 的已发布架构 (XSD) 文件本身，通过验证器运行它来确定问题。

在哪里可以找到 Amazon XSD 文件？

Answer 1

AmazonS3.xsd可用，还可咨询Amazon Simple Storage Service API Reference :

• Making Requests Using the REST API
• REST API
• Delete Multiple Objects
• Authenticating Requests (AWS Signature Version 4)

最后，特别是考虑到您对编码字符的担忧，请注意，您的请求实际上可能格式不正确，导致 XSD 验证无法发挥作用。 (参见 Well-formed vs Valid XML 。)他们的 API 文档中提供的示例就是这种情况，它引发了您收到的相同错误:
