Question

我正在尝试设置一个服务器来处理python中的多部分表单数据。我试图用curl命令打我的python服务器。

我收到Broken Pip Failure错误。

有人可以帮忙吗？

PYTHON服务器代码：

from BaseHTTPServer import BaseHTTPRequestHandler
import cgi
import cgitb
cgitb.enable(display=0,logdir="")

class PostHandler(BaseHTTPRequestHandler):

    def do_POST(self):
        print self.headers
        expect = self.headers['Expect']
        self.protocol_version='HTTP/1.1'
        print "Expect %s " % (expect)
        if expect.startswith('100') :
            print "Entered Expect section %s " % (self.protocol_version)
            self.send_response(100)
            print self.protocol_version
            #self.send_header("Content-Length","0")
            self.end_headers()
        else:
            con_length = int(self.headers['Content-Length'])
            print con_length
            content_type = self.headers['Content-Type']
            print content_type
            if content_type.startswith('multipart/form-data') :
                self.send_response(100)
                self.end_headers()
                self.wfile.write("Data:Krishnan");
                #self.rfile.read(con_length)
            else :
                print self.rfile.read(con_length)

                #Send the Response

                self.send_response(200)
                self.end_headers()
                self.wfile.write("Data:Krishnan")
        return

if __name__ == '__main__':
    from BaseHTTPServer import HTTPServer
    server = HTTPServer(('localhost',8000),PostHandler)
    print "Started Serving on HTTP Port 8000"
    server.serve_forever()

发送服务器的CURL命令：

curl -iv http://localhost:8000 -F myfile=@"/home/local/krishnan/messages.gz"

CURL回应：

* About to connect() to localhost port 8000 (#0)
*   Trying 127.0.0.1... connected

请帮助我！

当您检测到Expect:100-continue时，您只是使用100-continue进行响应，然后关闭连接。发送100-continue后，您需要阅读请求正文，如果正常，请回复200 OK。

def do_POST(self):
 ....
     self.send_response(100)
     self.end_headers()
     con_length = int(self.headers['Content-Length'])
     data = self.rfile.read(con_length)
     self.send_response(200)
     self.end_headers()
