Cloud amazon云驱动器rest api遇到https 400错误代码

我提出这个要求

https://www.amazon.com/ap/oa?client_id=amzn1.application-oa2-   
clientxxxxxxxxxxxxxxxxxxxxxxxxx&scope=clouddrive%3Aread%20clouddrive%3
Awrite&response_type=code&redirect_uri=https://roscasend.go.ro:8443/

我已成功重定向到此页面

 https://roscasend.go.ro:8443/?code=cccccccoooooodeeeeeee&scope=
 clouddrive%3Aread+clouddrive%3Awrite

但是当从以下请求更新字段时

 POST https://api.amazon.com/auth/o2/token HTTP/1.1
 Host: api.amazon.com
 Content-Type: application/x-www-form-urlencoded
 Cache-Control: no-cache
//those are the post's request arguments
grant_type=authorization_code&code=cccccccoooooodeeeeeee
&client_id=amzn1.application-oa2-clientxxxxxxxxxxxxxxxxxxxxxxxxx&
client_secret=secret______________________&redirect_uri=   
http%3A%2F%2Froscasend.go.ro%3A8443

使用我的凭据，我将遇到400错误

关于如何更新上述请求以便工作，您能给我任何解决方案吗

请注意，第一个请求在浏览器中，第二个请求通过java。

Hi aurelianr，您上面发布的代码最终解决了您的问题吗？或者你只是提供一个更新并分享你的源代码以供审查。你好，贾斯汀。上面的代码解决了我的问题。但是你必须小心。在此请求之后：clientxxxxxxxxxxxxxxxxxxxxx&scope=clouddrive%3read%20clouddrive%3 Awrite&response\u type=code&redirect\u uri=您将成功重定向到此页面clouddrive%3read+clouddrive%3write。请注意，您需要https重定向ulr才能工作。如果您对amazon cloud drive api有任何问题，我很乐意帮助您
