如何在不注入链的情况下获得操作的哈希值

您可以使用rpc使用节点远程伪造操作: /chains/main/blocks/head/helpers/forge/operations. 这是一个POST请求,您必须提供一个json文件,例如: {"branch":block_hash," contents":操作列表}. 操作类型有些棘手,您可以在 http://tezos.gitlab.io/mainnet/api/rpc.html#post-block-id-helpers-forge-operations . 因此,操作的哈希取决于"分支",通常将其视为头哈希.如果使用相同的"分支"注入它,则将具有相同的哈希,但是要小心,因为"分支"在64个级别后将变得无效. 如果使用的是客户端,还可以将带有-D选项的transfer命令与" dry-run"一起使用,这将完成所有伪造和检查工作,但只会进行伪造注射.

You can forge operations remotly using a node, with the rpc : /chains/main/blocks/head/helpers/forge/operations. This is a POST request, you have to give a json file like: { "branch" : block_hash, "contents" : operation list}. Operation type is a bit tricky, you can find some documentation in http://tezos.gitlab.io/mainnet/api/rpc.html#post-block-id-helpers-forge-operations. So the hash of the operation depends on the "branch" which is normally taken as the head hash. If you inject it with the same "branch" it will have the same hash, but be careful since the "branch" becomes invalid after 64 levels. If you are using the client, you can also use the transfer command with the -D option as "dry-run", that will do all the work of forging and checking but only do a fake injection.
