[1]完成卷曲-v -get --data-urlen code数据的https： //ec2.amazonaws.com/?action=DescribeRegions

[2]完成AWSAccessKeyId =

[2] Done AWSAccessKeyId=

[3]实现的版本= 2013年2月1日

[3] Done Version=2013-02-01

[4]就可以完成时间戳= 2013-05-24T12％3A35％3A00Z

[4] Done Timestamp=2013-05-24T12%3A35%3A00Z

[5] - 完成SignatureVersion = 2

[5]- Done SignatureVersion=2

[6] +完成=是SignatureMethod HmacSHA256

[6]+ Done SignatureMethod=HmacSHA256

我签署了这项请求查询follwing CMD庆典素文字

i signed this request query follwing cmd bash scipt

 #!/bin/bash

q='GET
ec2.amazonaws.com
/
AWSAccessKeyId=<aws acces_key>&Action=DescribeRegions&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp=2013-05-24T12%3A35%3A00Z&Version=2013-02-01'

echo -n "$q" | openssl dgst -sha256 -hmac "<aws secret key>" -binary | openssl enc -base64

产量为：xkw62EsVWEpc3rodXADy4Q3LOquKKfHmVHrrIIGQCg0 = 然后我给了这个请求，卷曲分别距上述bash脚本。

output was : xkw62EsVWEpc3rodXADy4Q3LOquKKfHmVHrrIIGQCg0= and then i gave this curl request separately away from above bash script.

$curl -v -get --data-encode DATA https://ec2.amazonaws.com/?Action=DescribeRegions&AWSAccessKeyId=<aws access key>&Version=2013-02-01&Timestamp=2013-05-24T12%3A35%3A00Z&SignatureVersion=2&SignatureMethod=HmacSHA256&Signature=xkw62EsVWEpc3rodXADy4Q3LOquKKfHmVHrrIIGQCg0=

可以在任何1告诉我在哪里，我要去哪里呢？

can any 1 tell me where i m going wrong?

推荐答案

您需要引用请求URL。它包含有被除preTED你的shell字符。

You need to quote the request URL. It contains characters that are being interpreted by your shell.

线索是在输出线如[1]完成......。 URL中的＆号是造成URL的片段被作为背景子shell执行。这些线是外壳的报告，这些子shell完成。

The clue is in the output lines like "[1] Done ...". The ampersands in the URL are causing fragments of the URL to be executed as background subshells. These lines are the shell reporting that those subshells have finished.
