I have a problem of huge http response with a json slab, where only portion is point of interest. I cannot change the response structure. here is an example
{
"searchString": "search",
"redirectUrl": "",
"0": {
"numRecords": 123,
"refinementViewModelCollector": {},
// Lots of data here
"results": [
{
"productCode": "123",
"productShortDescription": "Desc",
"brand": "Brand",
"productReview": {
"reviewScore": 0
},
"priceView": {
"salePriceDisplayable": false,
},
"productImageUrl": "url",
"alternateImageUrls": [
"url1"
],
"largeProductImageUrl": "url4",
"videoUrl": ""
},
{
"productCode": "124",
"productShortDescription": "Desc",
"brand": "Brand",
"productReview": {
"reviewScore": 0
},
"priceView": {
"salePriceDisplayable": false,
},
"preOrder": false,
"productImageUrl": "url",
"alternateImageUrls": [
"url1"
],
"largeProductImageUrl": "url4",
"videoUrl": ""
}
]
//lots of data here
}
}
My point of interest is entries in results
Jason Array, but the are sitting in the middle of json
I created a small Play WS Client like this:
val wsClient: WSClient = ???
val ret = wsClient.url("url").stream()
ret.flatMap { response =>
response.body.via(JsonFraming.objectScanner(1024))
.map(_.utf8String)
.runWith(Sink.foreach(println))
}
this will not work because it will take whole json slab as Json object. I need to skip some data until "results":
entry appear in the stream, then start parsing entries and skip all the rest.
Any ideas how to do this?
