[原创] web_convert_param 函数应用
选取web 协议，用html方式录制baidu.com查询”linux技巧”,则在runtime-viewer回放看到查询关键词并非”linux技巧”而是URL编码结果。


改用url 模式录制，代码如后：
web_url("s",
"URL=http://www.baidu.com/s?wd=linux%BC%BC%C7%C9&cl=3",

"Resource=0",

"RecContentType=text/html",

"Referer=http://www.baidu.com/",

"Snapshot=t4.inf",

"Mode=HTTP",

LAST);

web_url("c.gif",

"URL=http://c.baidu.com/c.gif?t=0&q=linux%BC%BC%C7%C9",

"Resource=0",

"RecContentType=text/html",

"Referer=http://www.baidu.com/s?wd=linux%BC%BC%C7%C9&cl=3",

"Mode=HTTP",

LAST);

回放出错，经ethreal截包,确有:http 204错误。

Action.c(28): Error -26563: Non-empty response body is invalid with HTTP Status Code 204 (No Content) for "http://c.baidu.com/c.gif?t=0&q=linux%BC%BC%C7%C9"

[MsgId: MERR-26563]

为了参数化以及更正错误，正确的代码如后：
web_convert_param("encoderesult", "SourceString={keyword}","SourceEncoding=HTML",

"TargetEncoding=URL", LAST);

lr_log_message("encode=%s",lr_eval_string("{encoderesult}"));

web_url("s",

"URL=http://www.baidu.com/s?wd={encoderesult}&cl=3",

"Resource=0",

"RecContentType=text/html",

"Referer=http://www.baidu.com/",

"Snapshot=t4.inf",

"Mode=HTTP",

LAST);


lr_continue_on_error(LR_ON_ERROR_CONTINUE );

web_url("c.gif",

"URL=http://c.baidu.com/c.gif?t=0&q=linux%BC%BC%C7%C9",
