Java Learning -031-json--specific data acquisition (Jsonobject satisfies specific key values)

Some of the previous posts are about JSON overview, simple data acquisition, encapsulating Cssselector data acquisition methods, and whether Jsonobject contains Key_value, please read the relevant blog post yourself.

During routine interface test scripting, it is often necessary to obtain the values of other properties corresponding to the conditional matching data based on a specific condition. For example, in the interface test script that validates the order information, we first need to obtain the order list, then find the corresponding order by the order number, and then obtain the payment amount, distribution information and other data of the order, and of course, we can obtain the order information directly, and then obtain the corresponding data. This article mainly describes the first case, when the request response contains a number of similar data information lists, how to obtain a jsonobject that satisfies a specific key_value and obtain the corresponding key corresponding value.

At this point, Java Learning -031-json Five-specific data acquisition (Jsonobject to meet specific key values) The smooth end, I hope this article can give you a reference to the JSON.

Finally, very grateful to the pro-stop, I hope this article can be pro helpful. Warmly welcome the kiss to discuss together and progress together. Thank you so much! ^_^
