Question

我尝试解决编码问题，但这不起作用。

我有此错误：

Traceback (most recent call last):
  File "amazon.py", line 49, in <module>
    outfile=(data.encode('utf8'))
AttributeError: 'dict' object has no attribute 'encode'

# -*- coding: utf-8 -*-

from selectorlib import Extractor
import requests 
import json 
import encodings
from time import sleep



# Create an Extractor by reading from the YAML file
e = Extractor.from_yaml_file('selectors.yml')

def scrape(url):    
    headers = {

    # Download the page using requests

    r = requests.get(url, headers=headers)
    # Simple check to check if page was blocked (Usually 503)
    if r.status_code > 500:
        if "To discuss automated access to Amazon data please contact" in r.text:
            print("Page %s was blocked by Amazon. Please try using better proxies\n"%url)
        else:
            print("Page %s must have been blocked by Amazon as the status code was %d"%(url,r.status_code))
        return None
    # Pass the HTML of the page and create 
    return e.extract(r.text)

# product_data = []
with open("urls.txt",'r') as urllist, open('output.jsonl','w') as outfile:
    for url in urllist.readlines():
        data = scrape(url) 
        if data:
            json.dump(data,outfile)
            outfile=(data.encode('utf8'))
            outfile.write("\n")
            # sleep(5)

使用以下方法解决：

json.dump(data,outfile,ensure_ascii=False)
