Python Scrapy：TypeError：to_bytes必須接收一個unicode，str或bytes對象，得到int

我不知道這段代碼有什麼問題。我正試圖從99acres.com上獲取數據。我已經通過了帖子參數。這是代碼Python Scrapy：TypeError：to_bytes必須接收一個unicode，str或bytes對象，得到int

from scrapy import Spider 
from scrapy.http import FormRequest 
from scrapy.selector import HtmlXPathSelector 


class aagSpider(Spider): 
    name = "acre" 
    start_urls = ["http://www.99acres.com"] 

    def parse(self, response): 
     frmdata3 = {"Refine_Localities": "Refine Localities", "action": "/do/quicksearch/search", "bedroom_num": "", 
        "budget_max": "", "budget_min": "", "city": 4, 
        "class": "", "fullSelectedSuggestions": "laxmi nagar, delhi east", "isvoicesearch": "N", 
        "keyword": "", 
        "keyword_suggest": "laxmi nagar, delhi east;", 
        "locality_array[]": "233", 
        "locality_array[]": "233", 
        "locality_array[]": "233", 
        "lstAcn": "HP_R", 
        "lstAcnId": "0", 
        "np_search_type": "NL,NP,R2M", 
        "preference": "S", 
        "property_type": "23", 
        "refine_results": "Y", 
        "res_com": "R", 
        "search_location": "HP", 
        "search_type": "QS", 
        "searchform": "1", 
        "selected_tab": "3", 
        "src": "CLUSTER", 
        "strEntityMap": "[{'type':'locality'},{'1':['laxmi nagar, delhi east','CITY_4, LOCALITY_233, PREFERENCE_S, RESCOM_R']}]", 
        "suggestion": "CITY_4, LOCALITY_233, PREFERENCE_S, RESCOM_R", 
        "texttypedtillsuggestion": "laxmi"} 

     yield FormRequest(response.url, callback=self.fourth, formdata=frmdata3) 

    def fourth(self, response): 
     print "11111111111111111111111111111111111111111111111111"

我試圖讓頁面通過上面的參數後，但要得到這埃羅

你能提供一個鏈接到你正在試圖抓取的最後一頁嗎？ – MetalloyD

可能由於「城市」：4'。嘗試用「城市」：「4」' –

謝謝保羅。它的工作現在。 – user3809411
