web_get_int_property（）--常用函数

该函数用于帮助我们返回有关先前HTTP请求的特定信息。

intweb_get_int_property（const int HttpInfoType）;

参数说明：

object：评估到类型为WebApi的对象的表达式。通常是webfor Java和Visual Basic。另请参见函数和常量前缀。

HttpInfoType：下面列出的选项之一。

一般信息：

web_get_int_property函数返回有关先前HTTP请求的特定信息。

返回值的含义取决于HttpInfoType参数。HttpInfoType可以是以下任何选项。每对中的第一个常量（HTTP_ *）用于C，第二个（对象.HTTP_ *）用于面向对象的语言。

HTTP_INFO_RETURN_CODE或object.HTTP_INFO_RETURN_CODE

HTTP响应标头中的返回代码。

HTTP_INFO_DOWNLOAD_SIZE或object.HTTP_INFO_DOWNLOAD_SIZE

最后一次下载的大小（以字节为单位），包括头，主体和通信开销（例如，NTLM协商）。

HTTP_INFO_DOWNLOAD_TIME或object.HTTP_INFO_DOWNLOAD_TIME

上次下载的时间（毫秒）。

HTTP_INFO_TOTAL_REQUEST_STAT或object.HTTP_INFO_TOTAL_REQUEST_STAT

返回自从首次使用HTTP_INFO_TOTAL_REQUEST_STAT发出web_get_int_property时所有标题和正文的累积大小。

HTTP_INFO_TOTAL_RESPONSE_STAT或对象.HTTP_INFO_TOTAL_RESPONSE_STAT

返回自从首次使用HTTP_INFO_TOTAL_RESPONSE_STAT发出web_get_int_property时所有响应的累积大小（包括标题和正文）

所有Web脚本和仅以HTTP模式运行的WAP脚本支持此功能。不支持以无线会话协议（WSP）重放模式运行的WAP脚本。

示例：web_get_int_property

以下示例使用web_get_int_property函数检查脚本是否成功访问了my_home主页。

但是返回状态200不一定页面的是成功，而是需要添加检查函数去判断更为合理。

{

int HttpRetCode;

web_url("my_home",

"URL=http://my_home",

"TargetFrame=_TOP",

LAST );

HttpRetCode =web_get_int_property(HTTP_INFO_RETURN_CODE);

if (HttpRetCode ==200)

lr_log_message("The scriptsuccessfully accessed the My_home home page");

else

lr_log_message("The script failed toaccess the My_home home page ");

}

Sample Output:

The scriptsuccessfully accessed the My_home home page

以下示例使用web_get_int_property函数返回URL和PDF下载的大小（以字节为单位）。Action()

{

int i;

int j;

lr_start_transaction("DownloadUrL");

web_url("club_registration.html",

"URL=https://secure.funclubreg.com/funclub.com/registration_form.html",

"Resource=0",

"RecContentType=text/html",

"Referer=",

"Snapshot=t1.inf",

LAST );

/* Code theweb_get_int_property function after the request

(such as web_urlor web_link) which starts the download.

i =web_get_int_property(HTTP_INFO_DOWNLOAD_SIZE);

lr_output_message("Thedownload size of the URL was: %d",i);

if(i > 10000)

{

lr_end_transaction("DownloadUrL",LR_PASS);

}

else

{

lr_end_transaction("DownloadUrL",LR_FAIL);

}

lr_start_transaction("DownloadPDF");

web_link("PDF version",

"Text=PDF version",

"Snapshot=t2.inf",

LAST );

j =web_get_int_property(HTTP_INFO_DOWNLOAD_SIZE);

lr_output_message("Thedownload size of the PDF file was: %d",j);

if(j > 10000)

{

lr_end_transaction("DownloadPDF",LR_PASS);

}

else

{

lr_end_transaction("DownloadPDF",LR_FAIL);

}

return 0;

}

Sample Output

Action.c(41): Thedownload size of the URL was: 148480

Action.c(45): Notify: Transaction "DownloadUrL" ended with"Pass" status (Duration: 13.2097).

...

Action.c(64): The download size of the PDF file was: 257381

Action.c(68): Notify: Transaction "DownloadPDF" ended with"Pass" status (Duration: 17.9892).
