  • Get和POST的区别

    2018-01-14 19:01:32

    GET
    请求URL中指明的资源或文件
    Asks to get the thing (resource / file) at the requested URL.
    POST
    请求服务器接收body信息,并将body信息发送给请求中指明的文件
    Asks the server to accept the body info attached to the request, and give it to the thing at the requested URL It’s like a fat GET… a GET with extra info sent with the request.
    两者区别
    1. 最关键的区别:POST有body。POST和GET都可以传递参数,但是用GET,传递的数据是有限制的,并且传递的参数直接附在Request line。

    1. 安全性。GET请求的参数会直接在浏览器输入栏中展示(在URL后用?分隔),如果涉及到密码的请求,你一定不希望其他看到。
    2. 添加收藏夹。你可能希望用户收藏这个请求页,GET可以收藏,但POST不能。
    3. 使用方式。GET用于请求信息(如简单的搜索),它不会改变服务器上的信息。POST用于发送数据,它既可以请求信息,也可以去更新服务器上的信息。

    SNMPv2 defines the get-bulk operation, which allows a management application to retrieve a large section of a table at once. The standard get operation can attempt to retrieve more than one MIB object at once, but message sizes are limited by the agent's capabilities. If the agent can't return all the requested responses, it returns an error message with no data. The get-bulk operation, on the other hand, tells the agent to send as much of the response back as it can. This means that incomplete responses are possible. Two fields must be set when issuing a get-bulk command: nonrepeaters and max-repetitions. Nonrepeaters tells the get-bulk command that the first N objects can be retrieved with a simple get-next operation. Max-repetitions tells the get-bulk command to attempt up to Mget-next operations to retrieve the remaining objects.

    Assume we're requesting three bindings: sysDescr, ifInOctets, and ifOutOctets. The total number of variable bindings that we've requested is given by the formula N + (M * R), where N is the number of nonrepeaters (i.e., scalar objects in the request -- in this case 1, because sysDescr is the only scalar object), M is max-repetitions (in this case, we've set it arbitrarily to 3), and R is the number of nonscalar objects in the request (in this case 2, because ifInOctets and ifOutOctets are both nonscalar). Plugging in the numbers from this example, we get 1 + (3 * 2) = 7, which is the total number of variable bindings that can be returned by this get-bulk request.

    The Net-SNMP package comes with a command for issuing get-bulk queries. If we execute this command using all the parameters previously discussed, it will look like the following:

    $ snmpbulkget -v2c -B 1 3 linux.ora.com public sysDescr ifInOctets ifOutOctets

    system.sysDescr.0 = "Linux linux 2.2.5-15 #3 Thu May 27 19:33:18 EDT 1999 i686"

    interfaces.ifTable.ifEntry.ifInOctets.1 = 70840

    interfaces.ifTable.ifEntry.ifOutOctets.1 = 70840

    interfaces.ifTable.ifEntry.ifInOctets.2 = 143548020

    interfaces.ifTable.ifEntry.ifOutOctets.2 = 111725152

    interfaces.ifTable.ifEntry.ifInOctets.3 = 0

    interfaces.ifTable.ifEntry.ifOutOctets.3 = 0

    Since get-bulk is an SNMPv2 command, you have to tell snmpgetbulk to use an SNMPv2 PDU with the -v2c option. The nonrepeaters and max-repetitions are set with the -B 1 3 option. This sets nonrepeaters to 1 and max-repetitions to 3. Notice that the command returned seven variable bindings: one for sysDescr and three each for ifInOctets and ifOutOctets.

    Non-repeaters and maxRepetitions

    They are used in getBulk.

    Definition of Non-repeaters:- The Non-repeater specifies the number of variables in the variable-bindings list for which a single OID (lexicographic successor) is to be returned.

    Definition of maxRepetitions :- The max-repetitions specifies the number of OIDs (lexicographic successor)to be returned for the remaining variables (total variables - nonrepeaters)in the variable bindings list.

    For clearer understanding, Let us assume Nonrepeater=4, and Max-Repetitions=3;

    If get values with OID lists which are .1.3.6.1.2.1.11.1.0, .1.3.6.1.2.1.11.2.0 , .1.3.6.1.2.1.11.3.0, .1.3.6.1.2.1.11.4.0, .1.3.6.1.2.1.11.5.0, .1.3.6.1.2.1.11.6.0 , and the method is getNext.

    NonRepeater value is 4. So the first four variable returns a single lexicographic successor.

    Request OIDs ----> Response

    .1.3.6.1.2.1.11.1.0 ---> .1.3.6.1.2.1.11.2.0 and its value

    .1.3.6.1.2.1.11.2.0 ---> .1.3.6.1.2.1.11.3.0 and its value

    1.3.6.1.2.1.11.3.0 ---> .1.3.6.1.2.1.11.4.0 and its value

    .1.3.6.1.2.1.11.4.0 ---> .1.3.6.1.2.1.11.5.0 and its value

    The subsequent OIDs in the OIDs list to be returned the number of max-repetitions lexicographic successor.

    Request ---> Response

    .1.3.6.1.2.1.11.5.0 --> .1.3.6.1.2.1.11.6.0, .1.3.6.1.2.1.11.7.0, .1.3.6.1.2.1.11.8.0 and its value.

    Request ---> Response

    .1.3.6.1.2.1.11.6.0 --> .1.3.6.1.2.1.11.7.0, .1.3.6.1.2.1.11.8.0 , .1.3.6.1.2.1.11.9.0 and its value.

    So the response will be,

    .1.3.6.1.2.1.11.2.0 and its value

    .1.3.6.1.2.1.11.3.0 and its value

    .1.3.6.1.2.1.11.4.0 and its value

    .1.3.6.1.2.1.11.5.0 and its value

    .1.3.6.1.2.1.11.6.0 and its value

    .1.3.6.1.2.1.11.7.0 and its value

    .1.3.6.1.2.1.11.7.0 and its value

    .1.3.6.1.2.1.11.8.0 and its value

    .1.3.6.1.2.1.11.8.0 and its value

    .1.3.6.1.2.1.11.9.0 and its value

  • GET和POST的区别

    2010-12-29 17:09:00
    GET is a simple request, POST can send user dataGET is the simplest HTTP method, and its main job in life is to ask the server to get a resource and send it back. That resource might be an HTML page, ...

     GET is meant to be used for getting things. Period, you might use the parameters to help figure out what to send back, but the point is—you’re not making any changes on the server! POST is meant to be used for sending data to be processed. This could be as simple as query parameters used to figure out what to send back, just as with a GET, but when you think of POST, think: update. Think: use the data from the POST body to change something on the server

    1.With GET, the parameter data is limited to what you can stuff into the Request line

    2.When you use GET, the parameter data shows up in the browser’s input bar,they are visible。

    3.GET requests can be bookmarked; POST requests cannot.

    4.The HTTP 1.1 spec declares GET, HEAD, and PUT as idempotent,
    even though you CAN write a non-idemtotent doGet() method yourself (but shouldn’t). POST is not considered idempotent by the HTTP 1.1 spec.


    GET is the simplest HTTP method, and its main job in life is to ask the server to get a resource and send it back. That resource might be an HTML page, a JPEG, a PDF, etc. Doesn’t matter. The point of GET is to get something back from the server.
    POST is a more powerful request. It’s like a GET plus plus. With POST, you can request something and at the same time send form data to the server (later in this chapter we’ll see what the server might do with that data).

    SNMPv2 defines the get-bulk operation, which allows a management application to retrieve a large section of a table at once. The standard get operation can attempt to retrieve

    more than one MIB object at once, but message sizes are limited by the agent's capabilities. If the agent can't return all the requested responses, it returns an error message with no data. The get-bulk operation, on the other hand, tells the agent to send
