我正在努力改进Scrapy，我面临着查询字符串和变量的新问题。
1)看起来查询字符串需要两个输入（storeInRadiusQuery & cache）：Here is the request headers with the API url
2)当我进入Params时，我有2个以JSON格式分组的查询字符串。在这个JSON中，有3个键（operationName、query和variables）。
在其他的Scrapy项目中，查询的格式要容易得多，但在这里我不知道如何用变量来处理这个问题。
我尝试了Formdata Scrapy方法，但没有成功：

data = {
        "operationName":"storeInRadiusQuery",
        "variables":{"currentLocation":"50.4376478855132,2.82123986359978","service":[],"storeChain":[],"deliveryTypes":[],"date":[],"__typename":"storeLocatorFilters"},
        "query":"query storeInRadiusQuery($currentLocation: String!, $service: [String], $storeChain: [String], $deliveryTypes: [String], $date: [String]) {\n  viewer {\n    storesInRadius(currentLocation: $currentLocation, services: $service, storeChaine: $storeChain, deliveryTypes: $deliveryTypes, date: $date, radius: 20, isStoreLocator: true) {\n      source {\n        ...StoresMapStoreItemType\n        ...StoreLocatorList\n        store_location\n        sort\n        __typename\n      }\n      __typename\n    }\n    __typename\n  }\n}\n\nfragment StoreLocatorList on StoreItemType {\n  store_id\n  store_name\n  street\n  zip_code\n  city\n  seo_url\n  day_0\n  day_0_morning_open_time\n  day_0_morning_close_time\n  day_0_afternoon_open_time\n  day_0_afternoon_close_time\n  day_1\n  day_1_morning_open_time\n  day_1_morning_close_time\n  day_1_afternoon_open_time\n  day_1_afternoon_close_time\n  day_2\n  day_2_morning_open_time\n  day_2_morning_close_time\n  day_2_afternoon_open_time\n  day_2_afternoon_close_time\n  day_3\n  day_3_morning_open_time\n  day_3_morning_close_time\n  day_3_afternoon_open_time\n  day_3_afternoon_close_time\n  day_4\n  day_4_morning_open_time\n  day_4_morning_close_time\n  day_4_afternoon_open_time\n  day_4_afternoon_close_time\n  day_5\n  day_5_morning_open_time\n  day_5_morning_close_time\n  day_5_afternoon_open_time\n  day_5_afternoon_close_time\n  day_6\n  day_6_morning_open_time\n  day_6_morning_close_time\n  day_6_afternoon_open_time\n  day_6_afternoon_close_time\n  __typename\n}\n\nfragment StoresMapStoreItemType on StoreItemType {\n  store_id\n  store_name\n  store_location\n  zip_code\n  street\n  city\n  seo_url\n  __typename\n}\n"}

    url = "https://www.monoprix.fr/api/graphql?storeInRadiusQuery&cache"

    yield scrapy.FormRequest(url,
                                method='POST', 
                                body=json.dumps(data), 
                                headers={'Content-Type':'application/json'},
                                callback=self.parse)

我看过this post关于如何处理查询字符串的说明，但是我不知道如何正确地把查询字符串放入字典中。
在这里我想试着修改一下当前位置和半径参数，找到一个店铺列表。
如果你有任何想法...谢谢！
