Description
Technical field
The present invention relates to the processing technology field of network data request, lifted on specifically a kind of Android under network
Carry the optimisation strategy of speed.
Background technology
Socket connections are an interfaces programmed for TCP and UDP, and TCP connections etc. can be established by it.
TCP and udp protocol belong to transport layer.
HTTP is the agreement of an application layer, and it is actually also established on Transmission Control Protocol.
We can only use when transmitting data（Transport layer）ICP/IP protocol, but at that rate, if should not
With layer, just None- identified data content, if it is desired to make the data of transmission significant, then must use and arrive application layer protocol, answer
Have much with layer protocol, such as HTTP, FTP, TELNET etc., oneself it can also define application layer protocol.WEB uses http protocol
Make application layer protocol, to encapsulate HTTP text messages, then do transport layer protocol using TCP/IP and it is dealt on network.
TCP three-way handshake：Data are not transmitted in handshake procedure, server just starts to transmit number with client after shaking hands
According to ideally, TCP connections are once establish, TCP connection meetings before either party in communication two party actively disconnects
It is always maintained at down.
Socket connections, at least need a pair of sockets, are respectively：ClientSocket and serverSocket.Even
Connect and be divided into 3 steps：
(1) server is monitored：The socket at server and delocalization specific client end, but the moment be in listening state；
(2) client request：The socket of client will describe the socket of its server to be connected, there is provided address and end
Slogan, then propose connection request to server socket；
(3) connection confirms：After server socket receives the request that client socket is sent, customer in response end is socketed
The request of word, and a new thread is established, client is issued in the description of the socket of server end.Once client confirms
This description, just formal establish connect.And server socket keeps listening state, the socket of other clients is continued to
The connection request of word.
HTTP is short connection：Client sends request and is required for server end back response.After request terminates, actively discharge
Link, therefore be short connection.Common practice is, it is not necessary to any data, also to keep sending out to server at regular intervals
Send the request of " keeping connection ".It can so ensure that client in server end is " reaching the standard grade " state.
HTTP connections use " request-response " mode, connection are not only established in request, and client is to service
After the request of device end, server ability returned data.
Socket connects to be long：Socket connections are exactly TCP connections under normal circumstances, therefore Socket connections are once built
Vertical, communication two party starts mutually to send out data content, until both sides disconnect.In actual applications, because network node is excessive,
In transmitting procedure, it can be disconnected by node, therefore active state is in by poll express network, the node.
The basic network connection HttpURLConnection provided in Android is the short company based on http protocol
Connect.
Advantage：
1st, the interface based on application layer is easy to use.
2nd, the development level required is not high, and fault-tolerance is strong.
Shortcoming：
1st, transmission speed is slow, and packet is big.
2nd, real-time, interactive is showed strictly according to the facts, server performance pressure is big.
3rd, data transmission security is poor.
So the problem of HttpURLConnection transmission speeds of the http protocol based on Android upper stratas are slow, is based on
Socket has the advantages of transmission data time is short, and performance is high.
The content of the invention
For defect present in prior art, it is an object of the invention to provide lifted on a kind of Android under network
