loadrunner回放時報Error -26377(web_reg_save_param)
搞了大半天，終於能正常通過web_reg_save_param獲取到自己想要的返回值了。
網上說了好多辦法，但是對我都沒用，我的辦法是先用web_reg_save_param函式獲取所有響應body體內容，然後根據返回的結果設定LB、RB值。
獲取整個響應body體方法。
web_reg_save_param("ResponseBody",
"LB=",
"RB=",
"Search=Body",LAST);//獲取所有的responsebody值。
如果使用LR11，使用web_reg_save_param_ex函式更好些。
web_reg_save_param_ex（
“ParamName=temp”,
"LB=",
"RB=",
"Ordinal=1",
SEARCH_FILTERS,
"ContentType=text/html",
LAST）;
示例：比如說從WEB頁面上看返回值為userid:10,username:十，那麼如果想獲取到userid的值：10方法如下：
方法一：通過返回頁面上格式設定LB和RB，這樣做一直是報錯，後來就嘗試了方法二。
web_reg_save_param_ex（
“ParamName=userid”,
"LB=userid:",
"RB=,username",
"Ordinal=1",
SEARCH_FILTERS,
"ContentType=text/html",
LAST）;
方法二：通過在日誌中檢視整個響應BODY體，來設定LB、RB。
web_reg_save_param_ex（
“ParamName=userid”,
"LB=\nuserid:",
"RB=,\nusername",
"Ordinal=1",
SEARCH_FILTERS,
"ContentType=text/html",
LAST）;
上述兩種方法可以看出，方法二變數前邊都多個換行符\n，我也不知道為什麼這樣就沒問題，但是檢視body體中變數前確實都加了\n，這樣設定就不報錯了。
其它人的解決方法通常如下，供大家參考。
Error -26377
web_set_max_html_param_len("1024");
Action.c(56): Error -26377: No match found for the requested parameter "returncodeVar". Check whether the requested boundaries exist in the response data.
Also, if the data you want to save exceeds 4096 bytes, use web_set_max_html_param_len to increase the parameter size
經測試發現...
web_set_max_html_param_len("1024");語句應該寫在web_reg_save_param(）之前，例如：
web_set_max_html_param_len("1024");
web_reg_save_param("returncodeVar",
"LB={\"returncode\":\"",
"RB=\"}",
"Ord=1",
LAST);
如果指令碼中多次用到web_reg_save_param(）應該每處都加上這句web_set_max_html_param_len()
辦法一不能解決的情況下，
解決辦法如下：設定runt time setting中的internet protocol-preferences中的advaced區域有一個winlnet replay instead of sockets選項，選項後再回放就成功了!
Error -27740
Action.c(5): Error -27740: Overlapped transmission of request to "192.168.4.177" for URL "http://192.168.4.177:8080/" failed: WSA_IO_PENDING

Troubleshooting
Add the following statement to the beginning of the script to disable the breakdown of the "First Buffer" into server and network time: web_set_sockets_option("OVERLAPPED_SEND", "0");
Error -27727
Action.c(5): Error -27727: Step download timeout (180 seconds) has expired when downloading resource(s). Set the "Step Timeout caused by resources is a warning" Run-Time Setting to Yes/No to have this message as a warning/error, respectively
一、Step download timeout (120 seconds)
這是一個經常會遇到的問題，解決得辦法走以下步驟：
1、修改run time setting中的請求超時時間，增加到600s,其中有三項的引數可以一次都修改了，HTTP-request connect timeout，HTTP-request receieve timeout，Step download timeout，分別建議修改為600、600、5000。run time setting設定完了後記住還需要在control元件的option的run time setting中設定相應的引數。
2、辦法一不能解決的情況下，解決辦法如下：
設定runt time setting中的internet protocol-preferences中的advaced區域有一個winlnet replay instead of sockets選項，選項後再回放就成功了。切記此法只對windows系統起作用，此法來自zee的資料。Error -27796
