Retrieving 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!

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
