Question

在尝试使用WSO2 ESB连接器删除驻留在Amazon S3中的文件时遇到问题。这是我所做的： 1）使用来自WSO2 documentation的以下内容，在WSO2 ESB中创建了代理服务：

2）我确保将代理服务部署到WSO2，然后使用POSTMAN 3）我向POSTMAN提交了以下内容：

<deleteObject>
<accessKeyId>MYACCESSKEY</accessKeyId>
<secretAccessKey>MYSECRETKEY</secretAccessKey>
<methodType>DELETE</methodType>
<contentType>application/xml</contentType>
<expect>100-continue</expect>
<region>us-east-1</region>
<host>s3.amazonaws.com</host>
<bucketUrl>http://s3.amazonaws.com/MYBUCKET</bucketUrl>
<bucketName>MYBUCKET</bucketName>
<isXAmzDate>true</isXAmzDate>
<objectName>FILETODELETE.txt</objectName>
<versionId></versionId>
</deleteObject>

我收到以下错误消息（消息开头）：

<?xml version="1.0" encoding="UTF-8"?>

我重新创建了S3凭据，但仍然遇到相同的错误，将不胜感激任何帮助。

坦率

在通过S3的删除对象之后，您需要检查标头值是否正确，因为访问Web服务之前需要进行身份验证，标头应如下所示。

DELETE /my-image.jpg?versionId=3HL4kqCxf3vjVBH40Nrjfkd HTTPS/1.1
Host: bucketName.s3.amazonaws.com
x-amz-mfa: 20899872 301749
Date: Wed, 28 Oct 2009 22:32:00 GMT
Authorization: AWS AKIAIOSFODNN7EXAMPLE:0RQf4/cRonhpaBX5sCYVf1bNRuU=

您可以将wso2 esb置于调试模式，并确认是否在适当的标头处传递了该标头，否则请使用TCPDUMP进行准确
