使用 SDK 在结构中进行用户注册时出错

Question

我正在尝试一次注册多个用户，但是在注册

时出现错误

"error: [FabricCAClientService.js]: Failed to enroll 0006, error:%o message=Enrollment failed with errors [[{"code":20,"message":"Authentication failure"}]], stack=Error: Enrollment failed with errors [[{"code":20,"message":"Authentication failure"}]]

at process._tickCallback (internal/process/next_tick.js:181:9)
Failed to register user: Error: Enrollment failed with errors [[{"code":20,"message":"Authentication failure"}]]"

我正在尝试用一个用户实现它运行良好，我们试图用多个用户实现它的给出错误。

谁能建议我多个用户如何在区块链中注册。

请参阅下面的注册用户.js文件

Answer 1

错误：身份验证失败

很明显，您提供了错误的凭据，这意味着错误的秘密

对于注册，我们需要ID和秘密

在继续注册之前，请仔细检查密钥并确保您已注册

Answer 2

我怀疑这个问题是因为您有编码错误(或 JSON 中的错误 ：-((。代码正在元素中查找userName字段，但 JSON 数组具有字段username(lc(。您可以轻松更改 JSON 以匹配。

Answer 3

如果要多次注册用户，则需要在ca.register的 json 中指定maxEnrollments。否则，ca.enroll将提示{ code: 20, message: 'Authentication failure'}。

例如，对于注册，您可能拥有

var secret = await ca.register({
enrollmentID: userDetails[i].enrollmentID,
userName: userDetails[i].userName,
role: userDetails[i].role,
maxEnrollments: -1 // -1 means no limit on number of enrollments after registration
}, adminIdentity);
