LR参数输出错误

龙雨

如下：使用lrs_save_searched_string函数可以获取linkID，但输出该参数时确未得到正确输出值。请高手指教，谢谢！脚本和日志如下：
脚本：
                lrs_save_searched_string("socket0",NULL,"linkID","LB=<link>","RB=</link>",1,0,-1);
                lr_output_message("%s",lr_eval_string("{linkID}"));

日志：
Action.c(92): lrs_save_searched_string(socket0, null, linkID, LB=<link>, RB=</link>, 1, 0, -1)
Action.c(92): callSaveParam: whence: received, socket: socket0, offset: 0, length: -1

lr_output_message(lr_eval_string("{linkID}"));试试

龙雨

谢谢楼上响应！
不过我使用建议操作lr_output_message(lr_eval_string("{linkID}"));尝试失败，结果同上面日志一样。
请教一下：lr_output_message(lr_eval_string("{linkID}"));和lr_output_message("%s",lr_eval_string("{linkID}"));两种表达方式有什么区别吗？

另补充：
上述是使用winsocket单协议。同样脚本当我使用winsocket和webservice多协议时运行正常，可以正确输出linkID参数值。
使用winsocket和webservice多协议时的日志如下：
Action.c(89): callRecv:332 bytes were received
Action.c(92): lrs_save_searched_string(socket0, null, linkID, LB=<link>, RB=</link>, 1, 0, -1)

msnshow

这两种写法没区别的，即然使用多协议可以，那只能说明winsocket协议不支持此函数了

龙雨

谢谢！
从日志上看感觉是 lr_eval_string()函数使用问题。
请问一下，使用winsocket单协议的话，还可以使用什么方法输出LR参数值以用于调试脚本？

龙雨

哇，已解决！
更改语句为lr_output_message(lr_eval_string("<linkID>"));解决问题。看来帮助文档还是很值得研究！

感谢云层、msnshow两位的响应。
