主題
這篇文章寫得很清楚
如何用 Hyperledger Composer 生成一個(gè)應(yīng)用
並運(yùn)行在 REST Server API 上
接下來(lái)透過(guò)此篇
把網(wǎng)頁(yè)建起來(lái)
我這邊記錄一下
中途可能會(huì)遇到的問題
401 error
首先，envvars.txt 這個(gè)檔案。
其中 COMPOSER_PROVIDERS 的"clientID"與"clientSecret"
要先至該 github網(wǎng)站 register a new OAuth application
填完就會(huì)各有一個(gè)"clientID"與"clientSecret"，然後將其填入 envvars.txt。
符號(hào)問題
‘ 改成 '
“ 改成 "
投票應(yīng)用
models
/**
* Write your model definitions here
*/
namespace org.basic.vote
participant voter identified by voterID {
o String voterID
o String fullName
}

o String voterID
o Boolean votedOrNot
}
asset candidateVote identified by politicalParty {
o String politicalParty
o Integer totalVote
}
transaction vote {
--> candidateVote candidateVoteAsset
--> ifVoted ifVotedAsset
}
logic.js
'use strict';

function vote(tx) {
if (!tx.ifVotedAsset.votedOrNot) {
tx.candidateVoteAsset.totalVote = tx.candidateVoteAsset.totalVote + 1;
return getAssetRegistry('org.basic.vote.candidateVote')
.then(function (assetRegistry) {
return assetRegistry.update(tx.candidateVoteAsset);
})
.then(function () {
return getAssetRegistry('org.basic.vote.ifVoted')
.then(function (assetRegistry) {
tx.ifVotedAsset.votedOrNot = true;
return assetRegistry.update(tx.ifVotedAsset);
})
});
}
