Question

我正在尝试创建2个文件。首先，回应.png（有效）。其次，取所有html并保存到文本。将html保存到文本文件只显示为空白。

def parse_request(self, response):

    # Works and saves file and png
    with open('image.png', 'wb') as f:
        f.write(response.body)

    # Creates file but doesnt have any text in it
    with open('text.txt', 'wb') as f:
        f.write(response.body.decode("utf-8"))

Answer 1

您是否尝试将response.body存储到变量，然后write该变量？

我认为你在第一次阅读时耗尽了流的反应。我也猜测你可能存储整个响应，而不仅仅是image.png文件中的png。

def parse_request(self, response):
    body = response.body
    # Works and saves file and png
    with open('image.png', 'wb') as f:
        f.write(body)

    # Creates file but doesnt have any text in it
    with open('text.txt', 'wb') as f:
        f.write(body.decode("utf-8"))

保存对文本文件的响应
