1、参数化空值
如上图所示，当参数化时某个值需要为空值（非空格），直接在参数化文件中空一行/格即可，虽然Parameter List界面上没有显示空的那一行，但并不影响取值。
2、手工日志跟踪
lr_set_debug_message(16|8,1); web_submit_data("upload_8", "Action=http://weblink-test.huawei.com/video/upload?method=Complete", "Method=POST", "RecContentType=text/html", "Referer=http://weblink-test.huawei.com/video/video/videoColligation.do?method=uploadVideo", "Mode=HTTP", ITEMDATA, "Name=fileUid", "Value={param_correnlation_fileUid}", ENDITEM, ... LAST); lr_set_debug_message(16|8,2);
3、LR中参数数组
参数数组的使用方法参考如下代码片段：
web_reg_save_param_ex( "ParamName=param_correlation_shippingMark", "LB=input readonly=\"readonly\" value=\"", "RB=\"", "Ordinal=All", SEARCH_FILTERS, "Scope=BODY", LAST); lr_start_transaction("GTM_ExpDecMaking_Edit"); web_submit_data("cntradeCustoms.do", "Action=http://nkperf.huawei.com/ces/gtm/expcc/cntradeCustoms.do", "Method=POST", "RecContentType=text/html", "Referer=http://nkperf.huawei.com/ces/gtm/expcc/cntradeCustoms.do?method=toDraftQuery&catalogId=11182", "Snapshot=t7.inf", "Mode=HTML", ITEMDATA, "Name=org.apache.struts.taglib.html.TOKEN", "Value={prama_correlation_token}", ENDITEM, "Name=method", "Value=toEditCustoms", ENDITEM, ... EXTRARES, "URL=http://app.huawei.com/commonresource/newstyle/en/images/loading.gif", ENDITEM, LAST); lr_end_transaction("GTM_ExpDecMaking_Edit", LR_AUTO); //-------------------------------------------------------------------------------- nshippingMark = lr_paramarr_len("param_correlation_shippingMark"); //lr_paramarr_len：取param_correlation_shippingMark关联变量数组的元素个数 while(nshippingMark > 0) //把关联到的参数数组的每一个元素的值连起来 { i = i + 1; strcat(szshippingMark," " ); //用一个空格进行连接 strcat(szshippingMark,lr_paramarr_idx("param_correlation_shippingMark", i)); //lr_paramarr_idx：从关联变量数组中取出指定元素的值 nshippingMark = nshippingMark - 1; } i = 0; lr_save_string(szshippingMark,"shippingMark_param"); lr_convert_string_encoding(lr_eval_string("{shippingMark_param}"),LR_ENC_SYSTEM_LOCALE,LR_ENC_UTF8,"shippingMark_param"); web_convert_param("shippingMark_param", "SourceEncoding=PLAIN", "TargetEncoding=URL", LAST ); //转成URL码时，空格会转成加号:+ szshippingMark_P = ReplaceStr(lr_eval_string("{shippingMark_param}"),"+","&="); //将空格替换成:&= lr_save_string(szshippingMark_P,"shippingMark_param"); //------------------------------------------------------------------------------------
