無(wú)法修改字典內(nèi)的頁(yè)碼

Python

我在 python 中編寫了一個(gè)腳本，使用 post 請(qǐng)求從網(wǎng)頁(yè)中獲取 json 內(nèi)容。如果我只堅(jiān)持它的默認(rèn)頁(yè)面，腳本就可以正常工作。但是，我的目的是創(chuàng)建一個(gè)循環(huán)來(lái)從幾個(gè)不同的頁(yè)面收集內(nèi)容。我正在努力解決的唯一問(wèn)題是使用page關(guān)鍵字內(nèi)payload來(lái)循環(huán)三個(gè)不同的頁(yè)面。將我的錯(cuò)誤方法視為占位符。如何在 dict 中使用格式來(lái)更改頁(yè)碼？工作腳本（如果我擺脫了分頁(yè)循環(huán)）：import requestslink = 'https://nsv3auess7-3.algolianet.com/1/indexes/idealist7-production/query?x-algolia-agent=Algolia%20for%20vanilla%20JavaScript%203.30.0&x-algolia-application-id=NSV3AUESS7&x-algolia-api-key=c2730ea10ab82787f2f3cc961e8c1e06'for page in range(0,3): payload = {"params":"getRankingInfo=true&clickAnalytics=true&facets=*&hitsPerPage=20&page={}&attributesToSnippet=%5B%22description%3A20%22%5D&attributesToRetrieve=objectID%2Ctype%2Cpublished%2Cname%2Ccity%2Cstate%2Ccountry%2Curl%2CorgID%2CorgUrl%2CorgName%2CorgType%2CgroupID%2CgroupUrl%2CgroupName%2CisFullTime%2CremoteOk%2Cpaid%2ClocalizedStarts%2ClocalizedEnds%2C_geoloc&filters=(orgType%3A'NONPROFIT')%20AND%20type%3A'JOB'&aroundLatLng=40.7127837%2C%20-74.0059413&aroundPrecision=15000&minimumAroundRadius=16000&query="} res = requests.post(link,json=payload.format(page)).json() for item in res['hits']: print(item['name'])按原樣運(yùn)行腳本時(shí)出現(xiàn)錯(cuò)誤：res = requests.post(link,json=payload.format(page)).json()AttributeError: 'dict' object has no attribute 'format'

format是一個(gè)字符串方法。您應(yīng)該將其應(yīng)用于您的字符串值payload：

payload = {"params":"getRankingInfo=true&clickAnalytics=true&facets=*&hitsPerPage=20&page={}&attributesToSnippet=%5B%22description%3A20%22%5D&attributesToRetrieve=objectID%2Ctype%2Cpublished%2Cname%2Ccity%2Cstate%2Ccountry%2Curl%2CorgID%2CorgUrl%2CorgName%2CorgType%2CgroupID%2CgroupUrl%2CgroupName%2CisFullTime%2CremoteOk%2Cpaid%2ClocalizedStarts%2ClocalizedEnds%2C_geoloc&filters=(orgType%3A'NONPROFIT')%20AND%20type%3A'JOB'&aroundLatLng=40.7127837%2C%20-74.0059413&aroundPrecision=15000&minimumAroundRadius=16000&query=".format(page)}

res = requests.post(link,json=payload).json()
