我如何才能使这个代码（谷歌街景）工作？我每次都会收到403条禁止的消息，即使我设置了一个用户代理

Question

所以我正在尝试一个下载谷歌街景图片的程序。地址位于.txt文件中。每次我尝试运行代码时，就会出现HTTP错误403:Forbidden。在我的实际代码中，我当然使用我的GoogleDeveloperAPI和正确的文件路径

我试图设置一个用户代理，但它就是不起作用。谁能帮帮我，我该怎么办？我如何在这段代码中实现它

# import os and urllib modules
# os for file path creation
# urllib for accessing web content

# this is the first part of the streetview, url up to the address, this url will return a 600x600px image

pre = "https://maps.googleapis.com/maps/api/streetview?size=600x600&location="

# this is the second part of the streetview url, the text variable below, includes the path to a text file containing one address per line
# the addresses in this text file will complete the URL needed to return a streetview image and provide the filename of each streetview image

text = r"C:\Users\.............

# this is the third part of the url, needed after the address
# this is my API key, please replace the one below with your own (google 'google streetview api key'), thanks!

        # creates the url that will be passed to the url reader, this creates the full, valid, url that will return a google streetview image for each address in the address text file
        URL = pre + ln + suf
        response = requests.get(URL, headers = headers)

        # you can run this up to this line in the python command line to see what each step does
        # final step, fetches and saves the streetview image for each address using the url created in the previous steps
        urllib.urlretrieve(URL, filename)
