post - 服务器不接受查询中的双引号

Question

我正在尝试提出与 here 相同的请求使用请求和Python。这是我的代码:

address = "0x800d0c1e4fb219a2d9bd2f292aa91abdcd862915"
data= """{"query":"{poolSnapshots(where:{pool:"%s"}, orderBy: date){id baseTokenLiquidity datatokenLiquidity spotPrice}}","variables":null,"operationName":null}"""%(address)
response = requests.post('https://v4.subgraph.polygon.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph', data=data).json()

但是当我执行代码时，出现以下错误:

GraphQL server error (client error): expected ,or} at line 1 column 39: 0

我错过了什么？我发短信时双引号错误吗？谢谢各位的解答!

API 需要一个包含在三引号中的字符串化 JSON。正确的方法是使用json.dumps将查询有效负载 (dict) 字符串化。它将把有效负载数据类型转换为相应的 JSON 类型。

import requests
import json

address = "0x800d0c1e4fb219a2d9bd2f292aa91abdcd862915"
url = 'https://v4.subgraph.polygon.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph'

data = {
    "query": "{poolSnapshots(where:{pool:\"%s\"}, orderBy: date){id baseTokenLiquidity datatokenLiquidity spotPrice}}" % address,
    "operationName": None,
    "variables": None,
}

response = requests.post(url, data=json.dumps(data))
print(response.json())
