我在Composer上整合了一个应用程序，它与Playground上的示例Bond网络非常相似。我的部分申请要求在到期日删除过期合同。因此，代码必须获取所有合同，找到日期小于当前合同的合同，并将其5字段更改为valid。下面是我运行的一些代码：
false现在，生成function SOD(sod) { // eslint-disable-line no-unused-vars
return getAssetRegistry('org.acme.otc.LiveContract')
.then(function (contractRegistry){
return contractRegistry.getAll();
})
.then(function (l){
allContracts=l;
//console.log('Curr List: ',allContracts);
var q = new Date();
var m = q.getMonth();
var d = q.getDay();
var y = q.getFullYear();
var date = new Date(y,m,d);
var arr=[];
allContracts.forEach(function(contract) {
//console.log('Contract Date: ',contract.contract.expiry);
if (contract.contract.expiry<date) {
//console.log('Checks Out');
//console.log('Destroying: ',contract);
arr.push(contract);
//console.log('Return: ',x);
}
})
return arr
}).then( function(arr){
var factory = getFactory();
new_arr=[];
fLen = arr.length;
for (i = 0; i < fLen; i++) {
var old_contract=arr[i];
console.log('ISIN: ',old_contract.ISINcode);
var new_contract = factory.newResource('org.acme.otc', 'LiveContract', old_contract.ISINcode);
console.log('Entry: ',old_contract);
new_contract.contract=old_contract.contract;
new_contract.valid=false;
new_arr.push(new_contract);
} x=invalidate(new_arr);
});
的代码效果很好。我可以在Playground中查看，我得到new_arr的以下日志：
但是，如果我在new_arr上调用invalidate或者在new_arr内复制该代码，则不会对注册表产生所需的影响。我在SOD字段下没有false。当我尝试在调试器中读取x时，我得到了跛足的Promise响应：
以下是我的.cto和.acl文件：
valid
//otc.cto namespace org.acme.otc
participant Trader identified by traderId {
o String traderId
o String name
o Boolean marginThresh // margin meeting maintenance minimum
}

}

}
concept Order {

//permissions.acl我对JavaScript缺乏经验，所以错误可能很少。谢谢你的帮助。
更新： 我在这里通过保罗的回应。我的新代码在
下面 rule Issuer {
description: "Allow full access to the issuer of a bond"
participant(i): "org.acme.otc.Trader"
operation: ALL
resource(a): "org.acme.otc.OpenOrder"
condition: (a.bond.issuer.memberId === i.memberId)
action: ALLOW
}
rule Default {
description: "Allow read access"
participant: "org.acme.otc.*"
operation: ALL
resource: "org.acme.otc.*"
action: ALLOW
}
rule SystemACL {
description: "System ACL to permit all access"
participant: "org.hyperledger.composer.system.Participant"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
rule NetworkAdminUser {
description: "Grant business network administrators full access to user resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "**"
action: ALLOW
}
rule NetworkAdminSystem {
description: "Grant business network administrators full access to system resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
然而它不起作用。代码似乎永远不会到达最终的/**

* @param {org.acme.otc.SOD} sod - the sod transaction
* @transaction
*/
function SOD(sod) { // eslint-disable-line no-unused-vars
//arr=pare();
var aR=null;
return getAssetRegistry('org.acme.otc.LiveContract')
.then(function (contractRegistry){
ar=contractRegistry;
return ar.getAll();
})
.then(function (l){
allContracts=[];
allContracts=l;
console.log('Curr List: ',allContracts);
var q = new Date();
var m = q.getMonth();
var d = q.getDay();
var y = q.getFullYear();
var date = new Date(y,m,d);
console.log('Current Date: ',date);
arr=[];
allContracts.forEach(function(contract) {
//console.log('Contract Date: ',contract.contract.expiry);
if (contract.contract.expiry<date) {
//console.log('Checks Out');
//console.log('Destroying: ',contract);
arr.push(contract);
//console.log('Return: ',x);
}
})
return arr
}).then( function(arr){
var factory = getFactory();
new_arr=[];
fLen = arr.length;
for (i = 0; i < fLen; i++) {
var old_contract=arr[i];
console.log('ISIN: ',old_contract.ISINcode);
var new_contract = factory.newResource('org.acme.otc', 'LiveContract', old_contract.ISINcode);
console.log('Entry: ',old_contract);
new_contract.contract=old_contract.contract;
new_contract.valid=false;
new_arr.push(new_contract);
}
console.log(new_arr);
});
console.log("getting to update the records");
return aR.updateAll(new_arr);
}
。以前的日志工作正常，其中的新合同是正确的。现在有什么想法吗？
答案 0 :(得分：1)
没有看到updateAll代码位或知道函数invalidate(new_arr)的作用 - 所以我会发布类似的东西，但你得到了要点 - 它在Playground中有效。 update和updateAll都适用于我。
我已粘贴下面的工作代码 - 只是从你的命名空间中给它一个事务/ TP装饰器等。
更新：
（我原来的帖子我会离开这里 - 因为它有效） - 我还更新了你的第二个新代码块的工作版本 - 但是有更正，例如。你没有正确引用对象（比如ar而不是应该是aR所以它永远不会更新注册表等） - 你需要按照你的方式遵循JS保证链完成它 - 所以我在下面的'ANSWER 2'中为你添加了代码。）。另外，最好将new_arr声明为具有全局函数范围，并且我已经在我的代码中完成了。
/**
* New script file
*/
/**
* A transaction processor function description
* @param { org.acme.otc.SOD } sod A human description of the parameter
* @transaction
*/
function SOD(sod) { // eslint-disable-line no-unused-vars
var aR = null;
return getAssetRegistry('org.acme.otc.LiveContract')
.then(function (contractRegistry){
// return contractRegistry.getAll();
aR = contractRegistry;
return aR.getAll();
})
.then(function (l) {
allContracts=[];
allContracts=l;
console.log('allContracts List is: ' + allContracts );
var q = new Date();
var m = q.getMonth();
var d = q.getDay();
var y = q.getFullYear();
var datevar = new Date(y,m,d);
arr=[];
allContracts.forEach(function(contract) {
console.log('Contract Date: ' + contract.contract.expiry);
if (contract.contract.expiry < datevar ) {
console.log('Checks Out - this contract needs fixing');
console.log('Destroying: ' + contract);
arr.push(contract);
//console.log('Return: ',x);
}
})
return arr
})
.then( function(arr) {
var factory = getFactory();
new_arr=[];
fLen = arr.length;
for (i = 0; i < fLen; i++) {
var old_contract=arr[i];
console.log('ISIN: ' + old_contract.ISINcode);
var new_contract = factory.newResource('org.acme.otc', 'LiveContract', old_contract.ISINcode);
console.log('Entry: ' + old_contract);
new_contract.contract=old_contract.contract;
new_contract.valid=false;
new_arr.push(new_contract);
} // x=invalidate(new_arr);
});
console.log("getting to update the records");
return aR.updateAll(new_arr);
//.then(function () {
// return getAssetRegistry('org.acme.otc.LiveContract')
//.then(function (contractRegistry){
// return contractRegistry.updateAll(new_arr);
// });
//});
}
答案2：使用第二个代码块更新代码

* @param {org.acme.otc.SOD} sod - the sod transaction
* @transaction
*/
function SOD(sod) { // eslint-disable-line no-unused-vars

var aR=null;
new_arr=[];
return getAssetRegistry('org.acme.otc.LiveContract')
.then(function (contractRegistry){
aR=contractRegistry;
return aR.getAll();
})
.then(function (l){
allContracts=[];
allContracts=l;
console.log('Curr List: ',allContracts);
var q = new Date();
var m = q.getMonth();
var d = q.getDay();
var y = q.getFullYear();
var date = new Date(y,m,d);
console.log('Current Date: ',date);
arr=[];
allContracts.forEach(function(contract) {
//console.log('Contract Date: ',contract.contract.expiry);
if (contract.contract.expiry < date) {
//console.log('Checks Out');
//console.log('Destroying: ',contract);
arr.push(contract);
//console.log('Return: ',x);
}
})
return arr
}).then( function(arr){
var factory = getFactory();
//new_arr=[];
fLen = arr.length;
for (i = 0; i < fLen; i++) {
var old_contract=arr[i];
console.log('ISIN: ',old_contract.ISINcode);
var new_contract = factory.newResource('org.acme.otc', 'LiveContract', old_contract.ISINcode);
console.log('Entry: ',old_contract);
new_contract.contract=old_contract.contract;
new_contract.valid=false;
new_arr.push(new_contract);
}
console.log("New Array is now " + new_arr);
})
.then(function () {
console.log("getting to update the records");
return aR.updateAll(new_arr);
});
