BITMEX API - 按给定符号取消订单 - 如何用 Dart 语言做?
BITMEX API - Cancel Order by given Symbol - How to do in Dart Language?
我尝试使用仅给出订单符号的 formData 发送取消订单请求。但不幸的是,所有其他订单也从交换中删除了……
我添加到请求中的 formData 似乎不起作用。
在 Dart 语言中,有没有人知道用 formData 向服务器发送取消请求的正确方法是什么?
非常感谢。
我花了将近 2 天的时间来弄清楚这一点:) 有一天,希望对像我这样需要的人有用..
这是我向 bitmex 发送取消订单的解决方案...用 dart 语言。
您还可以使用此代码创建有效的签名和身份验证..
