Wannan shi ne kashi na biyu a cikin jerin labaran ilimi kan ƙirƙirar kwangiloli masu wayo a Python akan hanyar sadarwa ta Ontology blockchain. A labarin da ya gabata mun saba da shi Ontology smart kwangila.
A yau za mu tattauna yadda ake amfani da module na biyu- API ɗin Adanawa. API ɗin Adanawa yana da APIs guda biyar masu alaƙa waɗanda ke ba da izinin ƙari, gogewa, da canje-canje zuwa ma'ajiya mai tsayi a cikin kwangiloli masu wayo akan blockchain.
A ƙasa akwai taƙaitaccen bayanin waɗannan APIs guda biyar:
Bari mu kalli yadda ake amfani da waɗannan APIs guda biyar.
0. Bari mu ƙirƙiri sabon kwangila
1. Yadda ake amfani da API Storage
GetContext & GetReadOnlyContext
GetContext и GetReadOnlyContext sami mahallin da ake aiwatar da kwangilar wayo na yanzu. Ƙimar dawowa ita ce sabanin hash ɗin kwangilar wayo na yanzu. Kamar yadda sunan ya nuna, GetReadOnlyContext yana ɗaukar mahallin karantawa kawai. A cikin misalin da ke ƙasa, ƙimar dawowa shine juzu'in hash ɗin kwangila wanda aka nuna a kusurwar dama ta sama.
Saka
aiki Saka yana da alhakin adana bayanai akan blockchain a cikin hanyar ƙamus. Kamar yadda aka nuna, Saka yana ɗaukar sigogi uku. GetContext yana ɗaukar mahallin kwangilar wayo mai gudana a halin yanzu, maɓalli shine ƙimar maɓallin da ake buƙata don adana bayanan, kuma ƙimar ita ce ƙimar bayanan da ke buƙatar adanawa. Lura cewa idan darajar maɓalli ya riga ya kasance a cikin kantin sayar da, aikin zai sabunta ƙimarsa daidai.
Get
aiki Get yana da alhakin karanta bayanan da ke cikin blockchain na yanzu ta hanyar ƙimar maɓalli. A cikin misalin da ke ƙasa, zaku iya cika ƙimar maɓalli a cikin zaɓin zaɓin da ke hannun dama don aiwatar da aikin kuma karanta bayanan da suka dace da ƙimar maɓalli a cikin blockchain.
share
aiki share yana da alhakin share bayanai a cikin blockchain ta hanyar ƙimar maɓalli. A cikin misalin da ke ƙasa, zaku iya cika ƙimar maɓalli don aikin a cikin zaɓin zaɓin da ke hannun dama kuma ku share bayanan da suka dace da ƙimar maɓalli a cikin blockchain.
2. Misalin lambar API Storage
Lambar da ke ƙasa tana ba da cikakken misali na amfani da APIs guda biyar: GetContext, Get, Saka, Share da GetReadOnlyContext. Kuna iya gwada shigar da bayanan API a ciki .

Ajiye blockchain shine jigon duk tsarin blockchain. API ɗin Adana Ontology yana da sauƙin amfani kuma yana da abokantaka.
A gefe guda, ajiya shine abin da ake mayar da hankali kan hare-haren hacker, kamar barazanar tsaro da muka ambata a cikin ɗaya daga cikin labaran da suka gabata- Ana buƙatar masu haɓakawa su ba da kulawa ta musamman ga tsaro lokacin rubuta lambar da ta shafi ajiya. Kuna iya samun cikakken jagora akan mu a nan.
A talifi na gaba za mu tattauna yadda ake amfani da su API ɗin Runtime.
