我有麻烦发送后请求，因为它返回一个错误400，而不是预期的204，尽管事实上，发送一个类似的请求在相同的风格似乎工作正常的其他部分相同的网站。
下面是一个接受google chrome请求的例子：

下面是我尝试发送请求的代码：

headers={"authorization": "TOKEN HERE"}
params={"username": "USERNAME", "discriminator": 9999}

r = requests.post("https://canary.discordapp.com/api/v6/users/@me/relationships",headers=headers,params=params)
print(r.status_code)

我以前收到过一个结构类似的删除聊天消息的请求，该请求工作正常：

requests.delete("http://canary.discordapp.com/api/v6/channels/" + CHANNEL ID + "/messages/" + MESSAGE ID, headers={"authorization": "TOKEN"})
