How do you send an HTTP Get Web Request in Python?
提问by LeChosenOne
I am having trouble sending data to a website and getting a response in Python. I have seen similar questions, but none of them seem to accomplish what I am aiming for.
我无法将数据发送到网站并在 Python 中获得响应。我见过类似的问题，但似乎没有一个能实现我的目标。
This is my C# code I'm trying to port to Python:
这是我尝试移植到 Python 的 C# 代码：
static void Request(Uri selectedUri)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(selectedUri);
request.ServicePoint.BindIPEndPointDelegate = BindIPEndPointCallback;
request.Method = "GET";
request.Timeout = (int)Timeout.TotalMilliseconds;
request.ReadWriteTimeout = (int)Timeout.TotalMilliseconds;
request.CachePolicy = CachePolicy;
request.UserAgent = UserAgent;
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (StreamReader responseReader = new StreamReader(response.GetResponseStream()))
{
string responseText = responseReader.ReadToEnd();
File.WriteAllText(UrlFileName, responseText.Trim(), Encoding.ASCII);
}
}
}
Here is my attempt in Python:
这是我在 Python 中的尝试：
def request():
web = httplib.HTTPConnection('https://someurl.com');
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
web.request("GET", "/heartbeat.jsp", headers);
response = web.getresponse();
stream = ""; #something is wrong here
Any help would be appreciated!
任何帮助，将不胜感激！

You can use urllib2
您可以使用urllib2
import urllib2
content = urllib2.urlopen(some_url).read()
print content
Also you can use httplib
你也可以使用httplib
import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("HEAD","/index.html")
res = conn.getresponse()
print res.status, res.reason
# Result:
200 OK
or the requests library
或请求库
import requests
r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
r.status_code
# Result:
200

In Python, you can use urllib2(http://docs.python.org/2/library/urllib2.html) to do all of that work for you.
在 Python 中，您可以使用urllib2( http://docs.python.org/2/library/urllib2.html) 为您完成所有这些工作。
Simply enough:
很简单：
import urllib2
f = urllib2.urlopen(url)
print f.read()
Will print the received HTTP response.
将打印收到的 HTTP 响应。
To pass GET/POST parameters the urllib.urlencode()function can be used. For more information, you can refer to the Official Urllib2 Tutorial
要传递 GET/POST 参数，urllib.urlencode()可以使用该函数。更多信息可以参考Urllib2官方教程
