[英]parse json response in Loadrunner
在 loadrunner 腳本中,我想解析收到的 json 響應並檢查響應是否正確。 為此,我有以下代碼:
web_set_max_html_param_len("999999");
web_custom_request("JsonData",
"URL=https://localhost:8080/testpgm",
"Method=POST",
"RecContentType=application/json",
LAST);
web_reg_save_param("JsonData",
"LB=",
"RB=",
"Search=Body",
LAST);
web_js_run(
"Code=getEmployee(LR.getParam('JsonData'));",
"ResultParam=Names",
SOURCES,
"File=getEMP.js",ENDITEM,
LAST);
javascript代碼如下:
function getEmployee(stringData)
{
var data = JSON.parse(stringData);
var index = data[data.length-1];
var value = data.ItemLists{0}.Items{0}.NamedValues{0}.Value{1}.name;
return value;
}
它不起作用,我收到以下錯誤:
Action.c(43): web_js_run started [MsgId: MMSG-26355]
Action.c(43): Error -26000: Error from JS Engine: "C:\Users\admin\Documents\VuGen\Scripts\Web1\getEMP.js:5:SyntaxError: missing ; before statement
" [MsgId: MERR-26000]
Action.c(43): Error -35051: Failed to run the JavaScript code [MsgId: MERR-35051]

Action.c(43): Error -26377: No match found for the requested parameter "JsonData". Check whether the requested boundaries exist in the response data. Also, if the data you want to save exceeds 999999 bytes, use web_set_max_html_param_len to increase the parameter size [MsgId: MERR-26377]
Action.c(43): Error -26374: The above "not found" error(s) may be explained by header and body byte counts being 0 and 0, respectively. [MsgId: MERR-26374]

相關函數(web_reg_save_param)應該放在請求之前。 嘗試
web_set_max_html_param_len("999999");
web_reg_save_param("JsonData",
"LB=",
"RB=",
"Search=Body",
LAST);
web_custom_request("JsonData",
"URL=https://localhost:8080/testpgm",
"Method=POST",
"RecContentType=application/json",
LAST);
web_js_run(
"Code=getEmployee(LR.getParam('JsonData'));",
"ResultParam=Names",
SOURCES,
"File=getEMP.js",ENDITEM,
LAST);
