我想将嵌套的JSON发布到服务器中。但是我在postman中使用以下标题和嵌套的JSON获得了成功，并且在通过java代码发布时出错，我在下面添加了我的代码。
header("Content-Type", "application/json")
header("Accept", "application/json")

如果我运行此代码意味着我收到错误
Errorjava.lang.IllegalArgumentException: Must supply an even number of key value pairs
答案 0 :(得分：0)
使用data，您可以指定查询参数。字符串数必须是偶数，它们被解释为键值对。
我猜您的通话不需要查询参数，因此您可以将其完全删除。
