BaseHTTPServer POST请求 - 连接重置

我正在构建一个简单的Python工具,它通过COM端口从外部接收器获取GPS坐标,并将其转换为Google Geolocation API返回的JSON字符串。目的是将Firefox中的Google Geolocation提供程序URL替换为将此字符串提供给浏览器的本地URL,从而在我的浏览器中实现基于GPS的位置。

GPS部分很好,但我在使用HTTP服务器将数据发送到浏览器时遇到问题。当浏览器向Google请求位置时,它会发送如下的POST:

POST https://www.googleapis.com/geolocation/v1/geolocate?key=KEY HTTP/1.1
Host: www.googleapis.com
Connection: keep-alive
Content-Length: 2
Pragma: no-cache
Cache-Control: no-cache
Content-Type: application/json
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36
Accept-Encoding: gzip, deflate, br

{}

这是我的回复代码:

from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer

PORT_NUMBER = 8080

class myHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        self.send_response(200)
        self.send_header('Content-type','application/json; charset=UTF-8')
        self.end_headers()
        self.wfile.write('{"location": {"lat": 33.333333, "lng": -33.333333}, "accuracy": 5}')
        return

try:
    server = HTTPServer(('', PORT_NUMBER), myHandler)
    print 'Started httpserver on port ', PORT_NUMBER
    server.serve_forever()

except KeyboardInterrupt:
    print 'Shutting down server'
    server.socket.close()

因此,当我从Curl发送一个空的POST请求时,它工作正常,但是当请求是浏览器发送的请求时(即正文中的#39; {}') :

curl --data "{}" http://localhost:8080
> curl: (56) Recv failure: Connection was reset

curl --data "foo" http://localhost:8080
> curl: (56) Recv failure: Connection was reset

curl --data "" http://localhost:8080
> {"location": {"lat": 33.333333, "lng": -33.333333}, "accuracy": 5}

我根本不熟悉HTTP协议或BaseHTTPServer。为什么会出错?我该如何解决呢?

1 个答案:

答案 0 :(得分:0)

我能想到的最好的是我需要对发布的内容做些什么,所以我只是将这两行添加到do_POST处理程序的开头:

    content_len = int(self.headers.getheader('content-length', 0))
    post_body = self.rfile.read(content_len)
