我正在尝试下订单，但我得到了urllib2.HTTPError：HTTP错误422：
我无法解决问题，我相信购买参数中存在一些语义错误。
我找不到任何相关的相关文档。

首先导入请求库
import requests
然后替换：
ret = urllib2.urlopen(urllib2.Request('https://poloniex.com/tradingApi', post_data, headers))
jsonRet = json.loads(ret.read())
by：
ret = requests.post('https://poloniex.com/tradingApi', data=req, headers=headers)
jsonRet = json.loads(ret.text)
查看帖子Sending a JSON POST using urllib2 results in HTTP 422以了解类似问题
答案 1 :(得分：2)
取代：
req ['nonce'] = int（time.time（）* 1000）
由：
req ['nonce'] = int（time.time（）* 1000000000）
答案 2 :(得分：1)
使用旧/存在的API / SECRET时遇到了同样的问题。尝试删除当前的API KEY并创建新的API。那它应该有效。
答案 3 :(得分：0)
我在打电话获得Poloniex公开订单时偶尔会回来422。 看着提琴手这是个问题：
Nonce必须大于1517395651712761。
我的应用程序是多线程的，因此另一个线程上的另一个请求必须将此“殴打”给Poloniex，即使它之后已创建（具有更大的nonce）。
