问题：URL=http://www.baidu.com/s?wd=%E6%B5%B7%E6%B7%80%E9%BB%84%E5%BA%84"中要对%E6%B5%B7%E6%B7%80%E9%BB%84%E5%BA%84进行参数化，但是由“中国”进行URL编码过来的（原因：URL的传参值，中文是无法进行ASCII编码的），所以无法直接用中文参数化，由于LR提供了lr_convert_string_encoding方法，所以要将中文进行URL编码和解码，是很容易的，故解决方法如下：   
  
 //URL编码
 lr_convert_string_encoding("中国",LR_ENC_SYSTEM_LOCALE, LR_ENC_UTF8 , "UnicodeString");

lr_save_string (lr_eval_string("{UnicodeString}"),"nURLencoder" );

web_convert_param("nURLencoder", "SourceEncoding=PLAIN", "TargetEncoding=URL",LAST );

lr_output_message("Url编码 = %s",lr_eval_string("{nURLencoder}"));

//URL解码
 lr_save_string (lr_eval_string("{nURLencoder}"),"URLencoder" );

web_convert_param("URLencoder", "SourceEncoding=URL", "TargetEncoding=PLAIN",LAST );

lr_convert_string_encoding(lr_eval_string("{URLencoder}"),LR_ENC_UTF8 ,LR_ENC_SYSTEM_LOCALE, "UnicodeString1");

lr_output_message("Url解码 = %s",lr_eval_string("{UnicodeString1}"));

---------------------------------------------------------------------------------------------------

///
    /// url编码
    /// 
    lr_convert_string_encoding(lr_eval_string("{NewParam}"),LR_ENC_SYSTEM_LOCALE, LR_ENC_UTF8 , "UnicodeString");

lr_save_string (lr_eval_string("{UnicodeString}"),"nURLencoder" );

web_convert_param("nURLencoder", "SourceEncoding=PLAIN", "TargetEncoding=URL",LAST );

//lr_output_message("nURLencoder=%s",lr_eval_string("{nURLencoder}"));

///
    /// url解码
    ///

lr_save_string(lr_eval_string("{nURLencoder}"),"URLencoder");

web_convert_param("URLencoder", "SourceEncoding=URL", "TargetEncoding=PLAIN",LAST );

//lr_output_message("URLencoder=%s",lr_eval_string("{URLencoder}"));

lr_convert_string_encoding(lr_eval_string("{URLencoder}"),LR_ENC_UTF8, LR_ENC_SYSTEM_LOCALE , "UnicodeString2");

//lr_output_message("UnicodeString=%s",lr_eval_string("{UnicodeString}"));

lr_error_message("原始值为=%s,编码为=%s,解码为=%s",lr_eval_string("{NewParam}"),lr_eval_string("{nURLencoder}"),lr_eval_string("{UnicodeString2}"));
