如何在Java中使用curl

这是我的curl代码

curl \

-F 'image1=YOUR_IMAGE_URL' \

-F 'image2=YOUR_IMAGE_URL' \

-H 'api-key:YOUR_API_KEY' \

https://url.org/

如何将其与HttpUrlConnection一起使用？您可以使用以下代码： `

`

您不能，您需要在java中使用http库。这是否回答了您的问题？你的问题不清楚。您可以简单地在java中进行系统调用并运行curl。但正如Jocke所说，通常的方法是通过编程来完成这些事情。换句话说，您必须花一些时间来学习如何用java编写利用http（s）连接的代码。请参阅建议的dupe，

-F

-s是表单字段，API键转到

setRequestProperty（）

。
