jayway 2.2.0删除jsonpath中的括号

Question

We just started using 2.2.0 jayway and it seems to have many differences than 0.9.1.

I am trying to get this item: $.[?(@.errorId=='200')].errorName[0] which worked in 0.9.1 by returning the value of errorName. In 2.2.0 it returns nothing. If I change it to $.[?(@.errorId=='200')].errorName I get back a string WITH brackets "[result]" which does not work for me. What should be the jsonPath in order to return a value and not an array?

Yes, jayway json path behavior changed. Now, whenever you use filter ('?') you will receive a java list in response. See "Indefinite paths" in https://github.com/jayway/JsonPath#what-is-returned-when

So you have to .get(0) on json path result...
