Python Scrapy: TypeError: to_bytes muss ein Unicode-, str- oder bytes-Objekt erhalten, int int

Question

Ich weiß nicht, was mit diesem Code nicht stimmt. Ich versuche, Daten von 99acres.com zu kratzen. Ich habe die Post-Parameter übergeben. Dies ist der Code

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"

Answer 1

Der Grund für dieses Problem ist, in Formulardaten, nie behandeln Null, Boolean (True/False) und Zahl wie sie sind. Behandle es immer als eine Schnur. In Python ist Null None, aber in Formulardaten ist es immer 'null'. Wahr oder Falsch wird als 'true' oder 'false' geschrieben. Für die Nummer, mach es zu einer Zeichenkette.
