java在Amazon aws中不允许针对此资源使用指定的方法

Question

伙计们，我可能是错的，也可能不是错的，但说真的，我正在努力解决AmazonS3存储桶中的文件上传问题。当我试图点击请求时，我得到了以下错误

MethodNotAllowed and The specified method is not allowed against this resource

上面的消息是下面的响应类型

<?xml version="1.0" encoding="UTF-8"?><Error><Code>MethodNotAllowed</Code
<Message>Thespecified method is not allowed against this resource.</Message>
<Method>POST</Method><ResourceType>OBJECT</ResourceType>
<RequestId>xxx</RequestId><HostId>xxxx</HostId></Error>

上面的消息是完整的消息，下面是我为上传文件到AmazonS3服务器而编写的代码

public synchronized boolean uploadFile(String url, String name, File file) {
    HttpEntity entity = MultipartEntityBuilder.create()
            .addPart("file", new FileBody(file)).build();
    HttpPost request = new HttpPost(url);
    request.setEntity(entity);
    HttpClient client = HttpClientBuilder.create().build();
    try {
        HttpResponse response = client.execute(request);
        entity = response.getEntity();
        if (entity != null) {
            try (InputStream in_stream = entity.getContent()) {
                BufferedReader in = new BufferedReader(new InputStreamReader(in_stream));
                String inputLine;
                StringBuilder responseBuffer = new StringBuilder();
                while ((inputLine = in.readLine()) != null) {
                    responseBuffer.append(inputLine);
                }
                in.close();
                String a = responseBuffer.toString();
                Utils.print("\n\n" + a + "\n\n");
            }
        }
        return true;
    } catch (Exception e) {
        Utils.print(e);
    }
    return false;
}

请建议我怎么做？我将非常感谢你期望的答案

您可能正在获取MethodNotAllowed，它建议使用属于bucket所有者帐户的标识

If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error. https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketPolicy.html

从S3API错误响应列表中

The specified method is not allowed against this resource.
