Question

我使用Zillow的API并调用GetDeepComps API。 API允许您在URL中包含地址，然后返回响应。

我想通过读取一个充满x地址的文本文件然后调用API x次来向API发送多个请求，直到文件中没有剩余地址为止。

变量formatted_addresses的值应根据包含地址的文本文件中读取的行而改变。

我还想将地址及其相应的邮政编码存储在字典中。这是我目前的代码。

def read_addresses_and_append_zip_codes():
    f = open("addresses.txt", "r")
    addresses = f.readlines()
    addresses = [x.strip() for x in addresses]
    print addresses
    formatted_address = "2723+Green+Leaf+Way"
    DEEP_SEARCH_RESULTS_BASE_URL = "http://www.zillow.com/webservice/GetDeepSearchResults.htm?zws-id=" + API_KEY + "&address=" + formatted_address + "&citystatezip=San%20Antonio%2C%20TX"
    response = requests.get(DEEP_SEARCH_RESULTS_BASE_URL)
    content = xmltodict.parse(response.content)
    zip_code = content['SearchResults:searchresults']['response']['results']['result']['address']['zipcode']
    print zip_code


read_addresses_and_append_zip_codes()

这是一个很好的方法吗？

我会像这样定义一些基本网址

BASE_URL = "http://www.zillow.com/webservice/GetDeepSearchResults.htm?zws-id={api_key}&address={encoded_addr}&citystatezip=San%20Antonio%2C%20TX"

然后，您可以使用API_KEY这样插入formatted_address和str.format()

new_url = BASE_URL.format(**{'api_key': API_KEY, 'encoded_addr': encoded_addr})

我们定义

import urllib
encoded_addr = urllib.quote_plus(addr)

然后整个事情看起来像这样：

def read_addresses_and_append_zip_codes():
    zips = {}
    BASE_URL = "http://www.zillow.com/webservice/GetDeepSearchResults.htm?zws-id={0}&address={1}&citystatezip=San%20Antonio%2C%20TX"
    with open("addresses.txt", "r") as f:
        addresses = f.readlines()
        addresses = [x.strip() for x in addresses]
        # print addresses
        for addr in addresses:
            encoded_addr = urlparse.quote_plus(addr)
            response = requests.get(BASE_URL.format(**{'api_key': API_KEY, 'encoded_addr': encoded_addr}))
            content = xmltodict.parse(response.content)
            zip_code = content['SearchResults:searchresults']['response']['results']['result']['address']['zipcode']
            zips[addr] = zip_code


read_addresses_and_append_zip_codes()

使用Python中的不同URL多次调用API
