Question

StringRequest 看起来工作正常，除了我尝试发送的签名。

我已经知道，如果其中任何一项不正确，Signature 就会失败：

如果您没有将签名放在 params Map 中的最后一个键处。
如果 API_SECRET 不正确，即使是一个空格。

我已经放置了所有必需的密钥，如果缺少一个，API 会返回适当的警告。

我使用 Python 获得了完全相同的签名，具有相同的时间戳，并且该顺序在 Python 中完美运行，但不适用于 Volley (Java)。

我担心 Volley 在发送订单时会更改相同值的格式，这就是签名与 Binance API 不匹配的原因。

我做错了什么？

我收到了这样的回复：

symbol=BNBBUSD&side=SELL&type=MARKET&quantity=1.12&timestamp=1610625131172

{symbol=BNBBUSD, side=SELL, type=MARKET, quantity=1.12, timestamp=1610625131172, signature=959725ca183e8dd024961c57b9be9e371fe59f81c98693820421b3df0314acbd}

Response Error = Signature for this request is not valid.

无法正确发送带有 Volley POST 请求的市价单 [响应：此请求的签名无效]
