rust - 如何捕获NEAR samart契约(Contract)日志(env::log)？

Question

我想在NEAR Rust智能合约测试运行时(不是终端)中捕获日志(env::log)并检查输出(在测试功能中)。我该怎么做？

尚未提供此功能。这是PR，它将把它介绍给near_sdk https://github.com/near/near-sdk-rs/pull/229。假设您提供了足够的可见性，也许您可​​以仅抓取执行该操作的代码。

/// Returns a copy of logs from VMLogic. Only available in unit tests.
pub fn get_logs() -> Vec<String> {
    let blockchain_interface =
        env::take_blockchain_interface().expect("Blockchain interface is not set");
    let logs = blockchain_interface
        .as_mocked_blockchain()
        .expect("MockedBlockchain interface expected")
        .logs();
    env::set_blockchain_interface(blockchain_interface);
    logs
}
