我使用audio file将audio & video bucket上传到名为demo的{{1}}。我得到AcrCloud RESTful services。这表明我的500 Internal Server Error（我在signature is correct时获得了422。我怀疑不正确的部分是构建多部分职位要求

获得的error message是：

我可以使用此AcrCloud上传音频文件：
命令：$ curl -H＆＃34; access-key：xxxx＆＃34; -H＆＃34;签名版本：1＆＃34; -H ＆＃34;时间戳：1439958502089＆＃34; -H＆＃34;签名： Nom6oajEzon260F2WzLpK3PE9e0 =＆＃34; -F＆＃34; title = fernando＆＃34; -F＆＃34; audio_id = 100＆＃34; -F ＆＃34; BUCKET_NAME =演示＆＃34; -F＆＃34; data_type = audio＆＃34; -F ＆＃34; audio_file = @ /用户/德拉塞雷纳/桌面/ ArcCloudMusic / Fernando.m4a＆＃34; https://api.acrcloud.com/v1/audios
有人对cUrl command有任何提示吗？或者是否有人成功地使用Java以编程方式使用此服务？或者有人可以告诉我如何打印HttpPOST请求的内容？
UPDATE 我也试过在GITHUB上使用他们的java示例：
https://github.com/acrcloud/webapi_example/blob/master/RESTful%20service/UploadAudios.java
我得到相同的how to debug this
更新我在运行代码时不再获得
500 error。我摆弄了apache jar版本，现在我可以成功使用git hub上的java代码了。为了记录，我使用的使用github代码的版本是apache-http-codec-1.10，apache-http-client-4.5，apache-http-core-4.4.1，apache-http-mime-4.5。 当我使用apache-http-core-4.5时，它无效。UPDATE 我编写了一个文件，打印出上面github引用上的java代码生成的签名，以及我自己的代码。签名匹配，所以我确信我正在构建多部分帖子请求的方式问题。我还将两个帖子请求的内容写入文件，标题包含几个点的不同信息。
答案 0 :(得分：0)
感谢Serena的耐心，我们的团队正在对代码和apache jar进行详细分析。希望很快会有更新。
目前，如果遇到同样问题的人，请使用https://github.com/acrcloud/webapi_example/blob/master/RESTful%20service/UploadAudios.java
