Question

我的使用Hyperledger作曲家REST API创建钱包的代码：

async function walletCreation(tx) {
var userId = {
userId: tx.userId,
};
var walletPassword = {
walletPassword: tx.walletPassword,
};

const encryptWalletId = await request.post({ uri: 
'http://payment.api.in/encrypt', json: userId });
const encryptWalletPassword = await request.post({ uri: 
'http://payment.api.in/encryptPass', json: walletPassword });
 return getAssetRegistry('com.payment.UserWallet')
.then(function (userAssetRegistry) {
  // Get the factory for creating new asset instances.
var factory = getFactory();
  // Create the wallet.
tx.walletId = encryptWalletId.walletId;
var walletAsset = factory.newResource('com.payment', 'UserWallet', 
tx.walletId);
walletAsset.userId = tx.userId;
walletAsset.walletPassword = encryptWalletPassword.walletPassword;
walletAsset.currency = tx.currency;
walletAsset.walletBalance = 0;
walletAsset.createdDate = new Date();
userAssetRegistry.add(walletAsset);


})
.catch(function (error) {

throw new Error("wallet creation failed");

});

}

下面是用于创建钱包的请求正文（Swagger输入）：

{
  "$class": "com.payment.WalletCreation",
  "userId": "Hari",
  "walletPassword": "hari@123",
  "currency": "INR",
  "walletBalance": 0
}

以下是上述输入的预期响应：

 {
   "$class": "com.payment.WalletCreation",
   "userId": "Hari",
   "status":"Wallet creation successfully",
   "WalletId":"1234567asder",
   "walletId": 0,
   "walletPassword": "hari@123",
   "currency": "INR",
   "walletBalance": 0,
   "transactionId": 
   "deee486e2e74647635e53e316f2a8e1b71ab500e9dd3bf15945665a4025fc208"
  }

但这就是得到的回应

  {
  "$class": "com.payment.WalletCreation",
  "userId": "Hari",
  "walletPassword": "hari@123",
  "currency": "INR",
  "walletBalance": 0,
  "transactionId": 
  "deee486e2e74647635e53e316f2a8e1b71ab500e9dd3bf15945665a4025fc208"
 }

请帮助我修复此问题，卡了2天无法修复该错误

Answer 1

https://hyperledger.github.io/composer/latest/integrating/call-out（第3个代码块）中有一个示例说明了您要尝试执行的操作，例如（用下面替换）

仅供参考，您无法重新分配tx.walletId（它是交易输入的一部分！）。另外，新的Date（）不确定。
响应完全是您对TRANSACTION帖子的期望-您需要使用/ GET在注册表'com.payment.UserWallet'中使用/ GET检查您正在创建的ASSET实例（资产）正在添加。此外，您期望的响应与您的功能不匹配。

从事务处理器功能返回复杂类型

链接：https://hyperledger.github.io/composer/latest/reference/js_scripts#returning-data-from-transaction-processor-functions

模型文件：


    namespace org.sample

    concept MyConcept {
        o String value
    }

    @returns(MyConcept)
    transaction MyTransaction {

    }

事务处理器功能：


    /**
     * Handle a transaction that returns a concept.
     * @param {org.sample.MyTransaction} transaction The transaction.
     * @returns {org.sample.MyConcept} The concept.
     * @transaction
     */
    async function myTransaction(transaction) {
        const factory = getFactory();
        const concept = factory.newConcept('org.sample', 'MyConcept');
        concept.value = 'hello world!';
        return concept;
    }
