CodePudding user response:
Do you want to
JsonObj variable string quotes

JsonObj='{" OPNAME ":" testname ", "APPLYNO" : "AbbrOP01", "OPACID:" 3424, "OPAMT:" 1000, "OPCURR" : "CNY", "OPCREA" : "LJY", "OPOWNR" : "RFS," "OPNEED" : "XUQIU", "OPCPTI" : "MINGXE", "OPCOMP" : "LUOSHI", "Shipto" : "10001", "Detail" : [{" OUPROD ":" WWREWS ", "OUMODE" : "WERWED", "OUQTY" : 1, "OUEXPP" : 1, "OUMINQ" : 1}]}'

Then you have to pass a json object with the following
Var jsonStr=JSON. Stringify (jsonObj);
