javascript - 从 $.ajax 站点到 python3 服务器的 Cookie

问题描述

基本上我到处寻找答案（谷歌），我似乎找不到解决方案。基本上我正在做的是我有一个 python 服务器来抓取网站并将它们返回到 json 中的页面（取决于 url）。服务器从您输入要搜索的位置和要搜索的内容的站点获取 url。我想做的是在整个过程中添加 cookie，因为您可以登录某些网站以获得折扣。我想不通的是我应该如何将我的网站 cookie 发送到我的服务器。我正在使用简化的代码来测试/找出它是如何工作的。

网站网址： http://localhost/looking/test.html

服务器网址： http://localhost:8082

服务器请求示例： http://localhost:8082/?search=dell&shop=rlyniceshop

解决方案

是的，所以我自己想通了。这也很容易做到。估计睡不好赶上我了。我所做的是创建一个新的var，cookie将存储在其中并将其作为数据发送。像这样：

var dat = Cookies.get()

$('.btn-outline-success').on('click', function(){
    var url = 'http://localhost:8082/?search=dell&parde=pls';
    $.ajax({
        url: url,
        method: "POST",
        data: dat
    });
});

然后使用get_POST从我的站点获取它们，如下所示：

def do_POST(self):
    self.send_response(200)
    self.send_header('Content-type','text/html; charset=utf-8')
    self.send_header('Access-Control-Allow-Origin', 'http://localhost')
    self.end_headers()
    content_length = int(self.headers['Content-Length'])
    body = self.rfile.read(content_length)
    parsed_q = urlparse(self.path)
    parsed_b = urlparse(body.decode("utf-8"))
    search_info = urllib.parse.parse_qs(parsed_q.query)
    user_info = urllib.parse.parse_qs(parsed_b.path)
    #print(''.join(wow['search']));
    print(search_info);
    print(user_info);
    message = "Json code"
    self.wfile.write(bytes(message, "utf8"))
    return

这样我可以保留我的标题并发送一些额外的数据（content_length）。我将 do_GET保存在python 代码中，只是为了将来我需要它。

我当前的代码现在看起来像这样：

        search_info = urllib.parse.parse_qs(parsed_q.query)
        user_info = urllib.parse.parse_qs(parsed_b.path)
        #print(''.join(wow['search']));
        print(search_info);
        print(user_info);
        message = "Json code"
        self.wfile.write(bytes(message, "utf8"))
        return

    def do_GET(self):

        self.send_header('Access-Control-Allow-Origin', '*')
        self.end_headers()
        message = "Nothing to see here."
        self.wfile.write(bytes(message, "utf8"))
        return

def run():
  print('starting server...')
  server_address = ('127.0.0.1', 8082)
  httpd = HTTPServer(server_address, testHTTPServer_RequestHandler)
  print('running server...')
  httpd.serve_forever()

run()

我希望这对将来正在寻找类似东西的人有所帮助:)
