opensea api v2-创建列表时无效订单签名

Question

我想通过Python通过Opensea API创建列表。我有回应：

{"errors":["['Invalid order signature']"]}

。我找不到文档中的信息。目前，我正在签署订单参数。这是我的代码：

import requests
from web3.auto import w3
from eth_account.messages import encode_defunct
import time


def create_order_model():
    current_time = int(time.time())
    order = {

        "offer": [
            {

    return order

def sing_order(msg):

    order_parameters = create_order_model()
    print(order_parameters)

    signature = sing_order(order_parameters)
    print(signature)

    params = {"parameters": order_parameters, "signature": str(signature)}
    response = requests.post(url, headers=headers, json=params)

（用于JavaScript的SDK：Https：//github.com/projectopensea/seaport-js/blob/blob/fb1c40d7760a8ee57777735735ad17f2bdb4a91ac7c6/seaeaport/seaeaport.seaport/seaport.tss.ts.ts.ts.l386.l386. i i i i i i is并试图将这个想法转换为Python。这就是我的sign_order外观转换的方式：

singOrder()

您知道如何正确签署Opensea API可以接受的订单？
    

是的，有一些警告。我解释了如何从Seaport SDK使用CreateDorder，然后在此GitHub链接中使用OpenSea API。 CreateOrder的结构与API结构略有不同。

Answer 1

，我遇到了相同的问题，然后我发现了溶解度，如果您试图使用mainnet u，您应该更改“链条”到1

ther以JavaScript和Seaport SDK遇到此错误的人。用1.4版初始化Seaport，而不是默认1.1
