How to retrieve the identity of the calling chaincode in Hyperledger Fabric Node SDK?
Oct 27, 2024 pm 08:39 PMRetrieving Caller Chaincode Identity in Hyperledger Fabric Node SDK
When invoking a chaincode through the APIstub.InvokeChaincode() method in Hyperledger Fabric Node SDK, the called chaincode (in this case, "fabcar") does not receive the ID of its caller (in this case, "Chaincode1"). This is because chaincodes lack explicit identities within the platform.
The getCreator() method, mentioned in the question, indeed provides the caller organization's identity. However, the desired information is the chaincode's ID or some unique identifier tied specifically to "Chaincode1."
Attempts to retrieve the caller chaincode ID through the getSignedProposal() method, as suggested in the question, have not been successful. The returned data does not contain an apparent reference to the calling chaincode's identity.
Consequently, it is currently not feasible to obtain the caller chaincode's identity within the called chaincode implementation.
The above is the detailed content of How to retrieve the identity of the calling chaincode in Hyperledger Fabric Node SDK?. For more information, please follow other related articles on the PHP Chinese website!

Golang is mainly used for back-end development, but it can also play an indirect role in the front-end field. Its design goals focus on high-performance, concurrent processing and system-level programming, and are suitable for building back-end applications such as API servers, microservices, distributed systems, database operations and CLI tools. Although Golang is not the mainstream language for web front-end, it can be compiled into JavaScript through GopherJS, run on WebAssembly through TinyGo, or generate HTML pages with a template engine to participate in front-end development. However, modern front-end development still needs to rely on JavaScript/TypeScript and its ecosystem. Therefore, Golang is more suitable for the technology stack selection with high-performance backend as the core.

In Go language, channel is used for communication and synchronization between goroutines. Declare the use of make function, such as ch:=make(chanstring), send the ch

In Go, using select statements can effectively handle non-blocking channel operations and implement timeout mechanisms. Non-blocking reception or sending operations are realized through the default branch, such as 1. Non-blocking reception: if there is a value, it will be received and printed, otherwise the default branch will be executed immediately; 2. Non-blocking transmission: If there is no receiver in the channel, the sending will be skipped. In addition, timeout control can be implemented in conjunction with time.After, such as waiting for the result or returning after 2 seconds. You can also combine non-blocking and timeout behaviors, try to get the value immediately, and wait for a short time after failure, so as to improve the program's concurrent response capabilities.

When encountering a "cannotfindpackage" error, it is usually because Go cannot find the target package or dependency. The solution is as follows: 1. Check whether the import path is correct and ensure that it is consistent with the module path or directory structure; 2. Confirm that the go.mod file has been initialized and use gomodinit and gomodtidy to manage dependencies; 3. Run goget to download missing dependencies or clean the module cache; 4. Make sure to execute commands in the correct directory context, or specify the complete module relative path for construction.

In Go, if you want the structure field to use a custom field name when converting to JSON, you can implement it through the json tag of the structure field. 1. Use the json: "custom_name" tag to specify the key name of the field in JSON. For example, Namestringjson: "username"" will make the Name field output as "username"; 2. Add, omitempty can control that the output is omitted when the field is empty, such as Emailstringjson: "email,omitempty""
