【问题描述】:
我在提交 HTTP Post 请求时遇到问题。我使用这个程序的目的是从网站上刮下歌词,然后在文本摘要器中使用该字符串。我在摘要器网站上提交 POST 请求时遇到问题。目前使用下面的代码,它不提交请求。它只是返回页面。我认为这可能是由于内容类型不同,但我不确定。
我的代码:
def summarize(lyrics):
url = 'http://www.freesummarizer.com'
values = {'text' : lyrics,
'maxsentences' : '1',
'maxtopwords' : '40',
'email' : 'your@email.com' }
headers = {'User-Agent' : 'Mozilla/5.0'}
cookies = {'_jsuid': '777245265', '_ga':'GA1.2.164138903.1423973625', '__smToken':'elPdHJINsP5LvAYhia6OAA68', '__smListBuilderShown':'true', '_first_pageview':'1', '_gat':'1', '_eventqueue':'%7B%22heatmap%22%3A%5B%7B%22type%22%3A%22heatmap%22%2C%22href%22%3A%22%252F%22%2C%22x%22%3A324%2C%22y%22%3A1800%2C%22w%22%3A640%7D%5D%2C%22events%22%3A%5B%5D%7D', 'PHPSESSID':'28b0843d49700e134530fbe32ea62923', '__smSmartbarShown':'true'}
r = requests.post(url, data=values, headers=headers)
print(r.text)

【问题讨论】:
-
“我的请求”不是请求,而是响应。另外,您的问题/问题到底是什么?您正在发送 POST 请求,但响应错误?
-
哦,抱歉,我提交的请求没有返回响应。打印出来的响应页面与“预请求”页面相同。
-
第一个框有响应头,第二个框有请求头。
