🥇Me pehea te hanga, te tohatoha me te whakamatautau Waves RIDE dApp

Kia ora! I roto i tenei tuhinga ka whakaatu ahau ki a koe me pehea te tuhi me te whakahaere i tetahi dApp auau i runga i te Waves node. Me titiro ki nga taputapu e tika ana, nga tikanga me tetahi tauira o te whanaketanga.

He rite tonu te kaupapa whanaketanga mo nga dApps me nga tono auau:

Waehere tuhi
Te tuhi whakamatautau aunoa
Te whakarewa i te tono
Whakamatau

Utauta

1. docker hei whakahaere i te node me te Waves Explorer

Ki te kore koe e pirangi ki te timata i te node, ka taea e koe te peke i tenei taahiraa. I muri i nga mea katoa, he whakamatautau me te whatunga whakamatautau. Engari me te kore e tuku i a koe ake node, ka toia pea te tukanga whakamatautau.

Ka hiahia koe ki nga kaute hou me nga tohu whakamatautau. Ka whakawhitihia e te korere whatunga whakamatautau 10 NGA NGARU ia 10 meneti.
Ko te wa poraka toharite i roto i te whatunga whakamatautau he 1 meneti, i roto i te node - 15 hēkona. Ka tino kitea tenei ina he maha nga whakapumautanga o te tauwhitinga.
Ka taea te keteroki pukuriri i runga i nga waahanga whakamatautau a te iwi.
Karekau pea i te waatea mo te wa poto na te tiaki.

Mai i tenei wa ka whakaaro ahau kei te mahi koe me to ake node.

2. Utauta Raina Whakahau Papa Ngaru

Tikiake me te whakauru i a Node.js ma te whakamahi ppa, homebrew, exe ranei i konei: https://nodejs.org/en/download/.
Tāutahia te Papa Ngarue, he taputapu e taea ai e koe te whakahaere i nga whakamatautau ki runga i tetahi node o naianei.

npm install -g @waves/surfboard

3. Visual Studio Waehere mono mono

Ko tenei taahiraa he mea kowhiri mena kaore koe i te powhiriwhiri ki nga IDE me te pai ki nga kaiwhakatika tuhinga. Ko nga taputapu e tika ana ko nga taputapu raina whakahau. Mena ka whakamahi koe i te vim, whakarongo ki te mono vim-ride.

Tikiake me te tāuta Visual Studio Code: https://code.visualstudio.com/

Whakatuwherahia te Waehere VS me te whakauru i te mono-rere:

Toronga pūtirotiro Waves Keeper: https://wavesplatform.com/products-keeper

Kua oti!

Tīmatahia te kōpuku me te Waves Explorer

1. Tīmatahia te kōpuku:

docker run -d -p 6869:6869 wavesplatform/waves-private-node

Kia mohio kei te whakarewahia te node ma te REST API in http://localhost:6869:

Swagger REST API mo te node

2. Tīmatahia he tauira o Waves Explorer:

docker run -d -e API_NODE_URL=http://localhost:6869 -e NODE_LIST=http://localhost:6869 -p 3000:8080 wavesplatform/explorer

Whakatuwheratia he kaitirotiro ka haere ki http://localhost:3000. Ka kite koe i te tere o te hanga i tetahi ara iahiko node paetata.

Ka whakaatu a Waves Explorer i tetahi tauira node paetata

Hanganga RIDE me te taputapu papa ngaru

Waihangahia he whaiaronga kau ka whakahaere i te whakahau ki roto

surfboard init

Ka arawhiti te whakahau i te raarangi me te hanganga kaupapa, nga tono me nga whakamatautau "kia ora te ao". Mena ka whakatuwhera koe i tenei kōpaki me te VS Code, ka kite koe:

Surfboard.config.json

I raro i te kōpaki ./ride/ ka kitea e koe he putea putea kotahi.ride - te whaiaronga kei reira te waehere dApp. Ka tātari poto matou i nga dApps i te poraka e whai ake nei.
I raro i te kōpaki ./test/ ka kitea he *.js kōnae. Ka penapenahia nga whakamatautau ki konei.
./surfboard.config.json – konae whirihoranga mo nga whakamatautau whakahaere.

Ko Envs tetahi waahanga nui. Kua whirihorahia ia taiao penei:

REST API mutunga o te node ka whakamahia hei whakarewa i te dApp me CHAIN_ID o te whatunga.
He kupu huna mo te kaute me nga tohu ka waiho hei puna mo o tohu whakamatautau.

Ka kite koe, ka tautokohia e surfboard.config.json nga taiao maha ma te taunoa. Ko te taunoa ko te taiao-a-rohe (ko te taviri defaultEnv he tawhā huri).

Tono putea-demo

Ehara tenei wahanga i te korero mo te reo RIDE. Engari, titiro ki te tono ka tukuna e matou ka whakamatautau kia pai ake ai te mohio ki nga mea e tupu ana i roto i te poraka.

Kia titiro tatou ki tetahi tono Pukoro-demo ngawari. Ka taea e te tangata te tuku tohu ki tetahi wahitau dApp. Ka taea e koe te tango i to WAVES anake. E rua nga mahi @Callable e waatea ana ma te InvokeScriptTransaction:

deposit()me whai utu taapiri i WAVES
withdraw(amount: Int)e whakahoki mai ana i nga tohu

Puta noa i te huringa ora o dApp, ka mau tonu te hanganga (whitau → moni):

Mahi
Te ahua hua

tuatahi
kore

E 5 nga ngaru ka tukuna e Alice
wāhitau alice → 500000000

E rua nga ngaru ka tukuna e Bob

wāhitau alice → 500000000
bob-address → 200000000

Ka tangohia e Bob nga ngaru e 7
KAUPAPA!

Ka tangohia e Alice nga ngaru e 4
wāhitau alice → 100000000
bob-address → 200000000

Anei te waehere kia tino mohio ki te ahuatanga:

# In this example multiple accounts can deposit their funds and safely take them back. No one can interfere with this.
# An inner state is maintained as mapping `address=>waves`.
{-# STDLIB_VERSION 3 #-}
{-# CONTENT_TYPE DAPP #-}
{-# SCRIPT_TYPE ACCOUNT #-}
@Callable(i)
func deposit() = {
 let pmt = extract(i.payment)
 if (isDefined(pmt.assetId))
    then throw("works with waves only")
    else {
     let currentKey = toBase58String(i.caller.bytes)
     let currentAmount = match getInteger(this, currentKey) {
       case a:Int => a
       case _ => 0
     }
     let newAmount = currentAmount + pmt.amount
     WriteSet([DataEntry(currentKey, newAmount)]) 
   }
 }
@Callable(i)
func withdraw(amount: Int) = {
 let currentKey = toBase58String(i.caller.bytes)
 let currentAmount = match getInteger(this, currentKey) {
   case a:Int => a
   case _ => 0
 }
 let newAmount = currentAmount - amount
 if (amount < 0)
   then throw("Can't withdraw negative amount")
   else if (newAmount < 0)
     then throw("Not enough balance")
     else ScriptResult(
       WriteSet([DataEntry(currentKey, newAmount)]),
       TransferSet([ScriptTransfer(i.caller, amount, unit)])
      )
 }
@Verifier(tx)
func verify() = false

Ka kitea hoki te waehere tauira i GitHub.

Ko te mono VSCode e tautoko ana i te whakahiato tonu i te wa e whakatika ana i tetahi konae. Na reira, ka taea e koe te aro turuki i nga hapa i te ripa PROBLEMS.

Ki te hiahia koe ki te whakamahi i tetahi ētita kuputuhi rereke i te wa e whakahiato ana i te konae, whakamahia

surfboard compile ride/wallet.ride

Ma tenei ka whakaputa i te raupapa o te waehere RIDE kua whakahiatohia e base64.

Whakamātautau hōtuhi mō 'wallet.ride'

Kia titiro tatou ki kōnae whakamātautau. Whakamanahia e te anga Mocha a JavaScript. He mahi "I mua" me nga whakamatautau e toru:

"I mua" ka putea nga kaute maha ma te MassTransferTransaction, ka whakahiatohia te tuhinga ka tukuna ki te poraka.
"Ka taea te whakatakoto" ka tukuna he InvokeScriptTransaction ki te whatunga, ka whakahohe i te mahi putunga() mo ia o nga kaute e rua.
“Kaore e taea te tango atu i nga mea i penapenahia” nga whakamatautau e kore e taea e tetahi te tahae nga tohu a etahi atu.
"Ka taea te whakatakoto" he tirotiro kei te tika te tukatuka o nga tangohanga.

Whakahaerehia nga whakamatautau mai i te Papa Ngaru me te tātari i nga hua i Waves Explorer

Hei whakahaere i te whakamatautau, rere

surfboard test

Mēnā he maha ō hōtuhi (hei tauira, ka hiahia koe ki tētahi hōtuhi whakatakotoranga motuhake), ka taea e koe te whakahaere

surfboard test my-scenario.js

Ka kohia e te papa ngaru nga konae whakamatautau i roto i te kōpaki ./test/ ka whakahaere i te hōtuhi i runga i te pona kua whirihorahia ki surfboard.config.json. Whai muri i etahi hēkona ka kite koe i tetahi mea penei:

wallet test suite

Hore! Kua paahitia nga whakamatautau. Inaianei me titiro tatou ki nga mea ka pa ki te whakamahi Waves Explorer: tirohia nga poraka, whakapiri ranei tetahi o nga wahitau i runga ake nei ki te rapu (hei tauira, wallet#. I reira ka kitea e koe te hitori tauwhitinga, te mana dApp, te konae rua kua whakahiatohia.

Waves Explorer. He tono katahi ano ka tukuna.

Ētahi Tohutohu Papa Ngarue:

1. Hei whakamatautau i te taiao testnet, whakamahia:

surfboard test --env=testnet

Tikina nga tohu whakamatautau

2. Ki te hiahia koe ki te kite i nga putanga JSON o nga tauwhitinga me te pehea e whakahaerea ai e te node, whakahaerehia te whakamatautau me te -v (ko te tikanga 'verbose'):

surfboard test -v

Te whakamahi taupānga me Waves Keeper

1. Whakaritea te Waves Keeper ki te mahi: http://localhost:6869

Te whakatu Waves Keeper ki te mahi me te node rohe

2. Kawemai he kupu huna me nga tohu mo te whatunga? Mo te ngawari, whakamahia te kakano tuatahi o to node: waves private node seed with waves tokens. Wāhi noho: 3M4qwDomRabJKLZxuXhwfqLApQkU592nWxF.

3. Ka taea e koe te whakahaere i tetahi tono wharangi korekore ma te whakamahi npm. Haere ranei ki te mea o mua: chrome-ext.wvservices.com/dapp-wallet.html

4. Whakauruhia te wahitau putea mai i te oma whakamatautau (kua tohua ki runga ake nei) ki roto i te pouaka kuputuhi wahitau dApp

5. Whakauruhia he moni iti ki te mara "Tapu" ka paato i te paatene:

Ka tono whakaaetanga a Waves Keeper ki te haina i tetahi InvokeScriptTransaction me te utu 10 WAVES.
