    variables = {"cursor":None,"count":10,"excludeMaker":None,"isExpired":False,"isFilled":None,"isValid":True,"maker":None,"makerArchetype":None,"makerAssetIsPayment":True,"takerArchetype":{"assetContractAddress":"0x7c40c393dc0f283f318791d746d894ddd3693572","tokenId":"7722"},"takerAssetCategories":None,"takerAssetCollections":None,"takerAssetIsOwnedBy":None,"takerAssetIsPayment":None,"sortAscending":None,"sortBy":"MAKER_ASSETS_USD_PRICE","makerAssetBundle":None,"takerAssetBundle":None}
    response = requests.post('https://api.opensea.io/graphql/', json={'query': query},data=variables)
    print(response.text)

（在变量中，“assetContractAddress”和“tokenId”对于项目是唯一的

但是，当我运行此命令时，我得到：

{"errors":[{"message":"Must provide query string."}]}

如果我在requests.post中不使用data=variables，我会得到：

{"errors":[{"message":"[400] One of taker_asset_categories, taker_asset_collections, maker, taker, maker, include_maker_assets, include_taker_assets, maker_assets, taker_assets, maker_asset_is_owned_by, taker_asset_is_owned_by, exclude_maker, maker_asset_bundle, taker_asset_bundle needs to be defined.","locations":[{"line":118,"column":3}],"path":["orders"]}],"data":{"orders":null}}

如何将requests.post与查询和变量一起使用以获得正确的响应

谢谢

Answer 1

您需要发送json数据中的变量，如下所示：

{
    "query": "your query",
    "variables": {
        "var1": "value1"
    }
}

签出this

例如：

import requests

query = """query OrdersQuery(\n  $cursor: String\n  $count: Int = 10\n  $excludeMaker: IdentityInputType\n  $isExpired: Boolean\n  $isFilled: Boolean\n  $isValid: Boolean\n  $maker:
