web_convert_param 函数在baidu.com搜索测试上的使用

用html方式录制baidu.com，比如查询”linux技巧”,则在runtime-viewer看到查询关键词并非”linux技巧”。

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]

Action.c(28):     \x00

Action.c(28): web_url("c.gif") highest severity level was "ERROR", 1 body bytes, 112 header bytes         [MsgId: MMSG-26388]。

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",

             "Resource=0",

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

             "Mode=HTTP",

             LAST);
