性能测试第六章-Loadrunner发送get和post请求

get：

webt_link和web_url函数

post：

Web_submit_form和Web_submit_data

webt_link和Web_submit_form依赖于上下文

web_url好Web_submit_data 不依赖于上下文，是绝对地址，一般使用这两种函数

函数形式：web_url( const char *StepName, const char *url, , [EXTRARES, ,] LAST ); 

示例1：发送一个GET请求至ABC的首页

web_url("www.abc.com", 
    "URL=http://www.abc.com/", 
    "TargetFrame=", 
    "TargetBrowser=Mercury Technologies", 
    "Resource=0", 
    "RecContentType=text/html", 
    "Snapshot=t1.inf", 
    "Mode=HTML", 
    LAST );

示例2：在Referer指定的页面发送一个HTTP请求

web_url("Hit the Slopes and Save", 
    "URL=http://www.saleserver.com/American?BV_EngineID=fm_ski_sale_fall00guest.html", 
    "TargetFrame=Main", 
    "Resource=0", 
    "RecContentType=text/html", 
    "Referer=http://www.saleserver.com/American?BV_Operation=
    Dyn_Frame&..main–guest.tmpl", 
    "Snapshot=t3.inf", 
    "Mode=HTML", 
    LAST ); 

示例3：下载示例

web_url("Games", 
    "URL=ftp://joe:secret@mygames.com/games/archive/loderunner.exe", 
    "FtpAscii=1", 
    LAST ); 

示例4：登录Secure站点

web_url("Login", 
    "URL=https://secure.computing.com/scripts/login.asp?
    user=(username)&session={ssid}", 
    "RecContentType=text/html", 
    LAST ); 

示例5：List of Resource Attributes的使用

web_reg_save_param("extrares_11", 
    "LB/IC=<img src="", 
    "RB="", 
    "Ord=11", 
    LAST ); 

web_url("web_url", 
    "URL=http://lazarus/html/links.html", //url必须的
    "TargetFrame=", 
    "Resource=0", 
    "Referer=", 
    "Mode=HTTP", 
    EXTRARES, 
    "URL={extrares_11}", ENDITEM, 
    LAST );

函数语法：Int web_submit_data ( const char *StepName, , ITEMDATA, , [ EXTRARES, ,] LAST );

返回值：LR_PASS（0）代表成功，LR_FAIL（1）代表失败。

web_submit_data("default.aspx",

"Action=http://lazarus/flightnet/default.aspx",//必须的

"Method=POST",

"TargetFrame=",

"RecContentType=text/html",

"Referer=http://lazarus/flightnet/",

"Snapshot=t7.inf",

"Mode=HTML",

ITEMDATA,   //以及下面的参数是必须的

"Name=grpType", "Value=radRoundtrip", ENDITEM,

"Name=btnAvailableFlights", "Value=Next >", ENDITEM,

LAST );

录制时可以在录制前设置选择web_url好Web_submit_data 方式来进行录制：

在Tools-->Recording Option-->Recording  点击进去，选择保存。
