In development, the more HTTP requests we use are basically get, POST. Where get is used to fetch data from the server, post is used primarily to submit some form data to the server, such as file uploads. And we encountered in the use of HTTP requests in the more troublesome thing is to construct the file upload HTTP message format, although the format is relativ

30.10SNMP Message Format　　Unlike most TCP/IP protocols, SNMP messages does not have a fixed fields. Instead, they use the standard ASN.1 encoding. Thus, a message can be difficult for humans to decode and understand. After examining the SNMP message definition in ASN.1 notation, we'll review the ASN.L encoding scheme b

HTTP message FormatThe HTTP message is divided into the request message and the response message, only the request message is sent, the response message will be.The common message

HTTP Request message Format:The HTTP request message consists of a request line, a request header, and a 3 part of the request body.1, Request lineConsists of 3 parts: The request method, the URL (see note 1), and the protocol version, separated by a spaceThe request method includes, PUT, POST, TRACE, OPTIONS, delete, and extension methods, not all of which are implemented by all servers, and some of which

be considered as an atomic operation only when reading a single byte. In this way, when the length of a data packet is greater than one byte, it cannot be read once by default. Therefore, a state machine is generally used to process network data streams. This state machine can be implemented very easily. The format of Length + Type + content can be seen as three States of the state machine. In the main logic of the program, we can process network dat

Because the need to do a SOAP interface docking, the other environment is not ready to grab the package, will only call do not understand the format structure, we just want to do a lightweight interface, do not need to support the specific SOAP format, only need to specify the interface specific parameter name, parse the string.Therefore, it is necessary to determine the

When a user enters an HTTP-based URL (a URL starting with http: //) in the browser, it is equivalent to notifying the browser to organize an HTTP request according to the URL, and send the request to the server. At the same time, wait for the response from the server. Both requests and responses are called HTTP messages. HTTP is divided into two parts: 1. http request message. 2. HTTP Response Message. 1.

TCP protocol specifies a common method for reliable data stream transmission between different hosts, such as connection establishment and release, message number, confirmation after receiving the datagram, traffic control, and sending timeout. I learned these things by rote, and I forgot it in a few days. I found that learning about this knowledge based on the TCP Message

Five SNMP protocol data units SNMP specifies five protocol data units PDU (that is, SNMP Packets) for exchange between management processes and proxies. Ø Get-Request: extract one or more parameter values from the Agent process (sent by the Network Management System) Ø Get-next-Request: extract the next parameter value that follows the current parameter value from the Agent process (sent by the Network Management System) Ø Set-Request: sets one or more parameter values of the proxy proc

make a few changes in servicecontract. For example: [Servicecontract]Public InterfaceIecho {[operationcontract, webget (uritemplate ="Echo/{input}")]StringEcho (StringInput);} so that you can use http: // serviceaddress/Echo/Inputvalue. [Message format control] If you want to return JSON or text? 1. Define servicecontract [Operationcontract]Message getuser

respectively, it ensures backward compatibility between IGMP version 1 and version 2. Maximum response time: The maximum time in 1/10 seconds before a response report is sent. The default value is 10 seconds. The new maximum response time (in 1/10 seconds) field allows the router to specify an accurate query interval response time for its Query Packets. IGMP version 2 hosts use this limit when randomly selecting their response time values. In this way, the query response interval helps to contr

HTTP messages are text-oriented, and each field in the message is a number of ASCII strings, and the length of each field is indeterminate. HTTP has two types of messages: Request messages and response messages.Request messageAn HTTP request message consists of a request line, a request header (header), a blank line , and 4 parts of the request data , giving the general

Key features of 1.TCP(1). TCP's connection-oriented Transport layer protocol;(2). Each TCP connection can have only two endpoints (endpoint), which is the connection between point to points, each endpoint is called socket (socket), Socket socket= (IP address: port number). (3). TCP provides reliable payment of services;(4). TCP provides duplex communication;(5). Byte stream oriented. header format for 2.TCP messag
