java - 如何解决hyperledger-fabric和java-sdk中的访问被拒绝 channel

Question

我遇到了一个问题。那是当我从命令行 java -jar something.jar 构建并运行我的 java 项目( HLF-Java-Sdk )时这很有效。但是当我运行我的项目时，我的意思是 main class as java application来自sts ide它给出了错误。在日志中我发现是 grpc error access denied 。之后我给出 sudo permission of the channel 。但它根本不起作用。同样的事情正在发生。

错误日志:

有什么建议我可以遵循来摆脱这个困境。 HyperLedger版本为1.4.1

Answer 1

我发现问题的解决方法是

• 创建usercontext时，我的意思是生成或读取admin.ser文件，该文件是 写入目录或从目录中读取(如果已创建)。

• 因此，对于我的情况，/some_dir/user/org1/admin.ser 该文件是在没有读取权限的情况下创建的。这就是为什么我收到权限被拒绝错误的原因。更改权限后或者如果我更改具有读/写权限的目录，它可以正常工作。

• 因此，更改基本上是我从 code 读取/写入 admin.ser

String directoryPath = System.getProperty("user.home") + File.separator + "users" + File.separator + userContext.getAffiliation(); // Just I am sharing my code. For understanding
