这是我的python代码：

import os
import sys
import urllib
import urllib.parse
import urllib.request


site = "http://genes.mit.edu/fas-ess/"
def getinfo(info):
    form_data = {'sequence':info}
    params = urllib.parse.urlencode(form_data)
    request = urllib.request.Request(site,bytes(params,encoding='UTF-8'))
    response = urllib.request.urlopen(request)
    print (response.read().decode('utf-8'))


if __name__ == "__main__":
    info = '>NM_000015\nATGGACATTGAAGCATATTTTGAAAGAATTGGCTATAAGAACTCTAGGAACAAATTGGACTTGGAAACATTAACTGACATTCTTGAGCACCAGATCCGGGCTGTTCCCTTTGAGAACCTTAACATGCATTGTGGGCAAGCCATGGAGTTGGGCTTAGAGGCTATTTTTGATCACATTGTAAGAAGAAACCGGGGTGGGTGGTGTCTCCAGGTCAATCAACTTCTGTACTGGGCTCTGACCACAATCGGTTTTCAGACCACAATGTTAGGAGGGTATTTTTACATCCCTCCAGTTAACAAATACAGCACTGGCATGGTTCACCTTCTCCTGCAGGTGACCATTGACGGCAGGAATTACATTGTCGATGCTGGGTCTGGAAGCTCCTCCCAGATGTGGCAGCCTCTAGAATTAATTTCTGGGAAGGATCAGCCTCAGGTGCCTTGCATTTTCTGCTTGACAGAAGAGAGAGGAATCTGGTACCTGGACCAAATCAGGAGAGAGCAGTATATTACAAACAAAGAATTTCTTAATTCTCATCTCCTGCCAAAGAAGAAACACCAAAAAATATACTTATTTACGCTTGAACCTCGAACAATTGAAGATTTTGAGTCTATGAATACATACCTGCAGACGTCTCCAACATCTTCATTTATAACCACATCATTTTGTTCCTTGCAGACCCCAGAAGGGGTTTACTGTTTGGTGGGCTTCATCCTCACCTATAGAAAATTCAATTATAAAGACAATACAGATCTGGTCGAGTTTAAAACTCTCACTGAGGAAGAGGTTGAAGAAGTGCTGAGAAATATATTTAAGATTTCCTTGGGGAGAAATCTCGTGCCCAAACCTGGTGATGGATCCCTTACTATTTAG'
    getinfo(info)

完整解释：

我要做的是将给定的字符串输入网站，提交，然后抓取结果页面。我曾尝试使用 urllib2 在 3.0 之前使用 python 翻译另一个线程，但我得到的唯一回报是原始网站 html。

谢谢你看看。

我会邀请您试用该网站： http:
//genes.mit.edu/fas-ess/

用这个查询

">NM_000015GTGATGGATCCCTTACTATTTAG"

您必须像 Jon Clements 解释的那样更改发送请求并将其添加set到您的 form_data：

site = "http://genes.mit.edu/cgi-bin/fas-ess.pl"
def getinfo(info):
    form_data = {'sequence':info, 'set':'FAS-hex2'}
