How to format a collection in json and save using the storage service

Sun, 14 Jul 2019 21:20:09 +0000

Using .net to build a server and save data from the server to App42, that clients will then retreive in unity3d.

I pull data from other API with the server ( financial data in that case ), that i put in a collection, and then try to save that on App42.
When i Serialize the collection via newtonsoft.json in C#, i get the followiing json :

[{"id":1,"name":"Bitcoin","symbol":"BTC","slug":"bitcoin","circulating_supply":"17817825","total_supply":"17817825","max_supply":"21000000","date_added":"2013-04-28T00:00:00Z","cmc_rank":1,"price_usd":10671.0584356,"price_btc":1.0,"volume_24h":23185304866.5182,"percent_change_1h":1.57316,"percent_change_24h":-3.85315,"percent_change_7d":-6.54577,"market_cap":190135051770.29456,"last_updated":"2019-07-14T21:13:30Z"},{"id":1027,"name":"Ethereum","symbol":"ETH","slug":"ethereum","circulating_supply":"106899675.5615","total_supply":"106899675.5615","max_supply":null,"date_added":"2015-08-07T00:00:00Z","cmc_rank":2,"price_usd":238.58230671,"price_btc":0.022357885878879574,"volume_24h":8582925524.28892,"percent_change_1h":1.12083,"percent_change_24h":-10.1693,"percent_change_7d":-21.368,"market_cap":25504371182.013287,"last_updated":"2019-07-14T21:13:19Z"}]

Which gives the following error when tryign to save that document :
com.shephertz.app42.paas.sdk.csharp.App42BadParameterException: {"app42Fault":{"httpErrorCode":400,"appErrorCode":2605,"message":"Bad Request","details":"Passed JSON string is not valid."}}
   at com.shephertz.app42.paas.sdk.csharp.connection.RESTConnectorAsync.ExecutePost(String url, Dictionary`2 paramsDics, String bodyPayLoad, Dictionary`2 headerParams)
   at com.shephertz.app42.paas.sdk.csharp.storage.StorageService.InsertJSONDocument(String dbName, String collectionName, String json)
   at com.shephertz.app42.paas.sdk.csharp.storage.StorageService.<InsertJSONDocument>c__AnonStorey0.<>m__0()

I am not sure how to serialize that collection in order for it to be "valid" ?

This is how i convert the collection ( using newtonsoft.Json )
string json = JsonConvert.SerializeObject(list_coin);
Storage storage = storageService.InsertJSONDocument(dbName,collectionName,json);

Any help would be greatly appreciated, as i am planning to use jsons a lot and wish for an easy converter to be used.

Effective way to edit all user's scores

Sun, 23 Apr 2017 23:34:54 +0000

You mentioned that the scoreBoardService.EditScoreValueById() can be used to reset user's score on leaderboard.

But this method can only update one user's score, not all users. I think it's impossible to call this method 10000 times if there are 10000 user scores in the score board.
Is there an API that can edit users' score all at once?

Best approach for resetting daily leaderboard

Wed, 19 Apr 2017 12:48:01 +0000

Hi, I have a daily leaderboard in my game and it needs to be reset every day. So what's the best approch for doing it? 1. Delete all user scores or set all user scores to -1. I couldn't find API for deleting all scores or setting all scores to a specific number. 2. Delete the entire game and recreate a new game. I can do it in the dashboard but I couldn't find the API for doing it programmtically.
