问题 I am pretty new to JSON and trying to construct a new JSON request file using Java.

问题 I am making a react app that searches for a book by title and returns the results. It's mostly working fine, but for some titles searched (such as "hello") it can't get the results because the parameters are missing. Specially, the "amount" value is missing, and it can get me e-books that are not for sale even if I add the filter=paid-ebooks param while fetching the api. Using projection=full doesn't help either. For example, when I call the api with https://www.googleapis.com/books/v1

问题 I want to write code to loop through a multidimensional array (4 or 5 deep) and echo all keys and values found and skip empty arrays. $drugs = fopen("http://dgidb.org/api/v2/interactions.json?drugs=FICLATUZUMAB", "r"); $json_drugs = stream_get_contents($drugs); fclose($drugs); $data_drugs = json_decode($json_drugs,true); foreach ($data_drugs as $key => $value) ... Anyone, anyone, Ferris? 回答1: Your $data_drugs is no longer a json, after json_decode is an associative array. You don't need any

问题 I am using anorm to query and save elements into my postgres database. I have a json column which I want to read as class of my own.

问题 I don't know whether this is a plotly question or an htmlwidgets question. Maybe it's both. I am using R to make plotly widgets, which are -- when made from R -- also htmlwidgets. When making plotly widgets in this way, the resulting HTML contains a stringified JSON object that includes the data and some settings for the widget. But only some parts of this JSON object are easily accessed from a Javascript console. For example, the "data" and "layout" objects are easily accessed, but the
