接收用户通过客户端发送的更新请求，更新请求中至少包含用户ID；Receiving an update request sent by the user through the client, where the update request includes at least a user ID;
验证用户ID是否与预置的ID列表匹配，若匹配，则接收用户的操作信息，并根据操作信息更新本地库存数据。Verify that the user ID matches the preset ID list. If it matches, the user's operation information is received, and the local inventory data is updated according to the operation information.
每个库房的节点设备可以由一个或多个管理人员进行数据管理，可以为每个用户分配特定的权限，为每一项操作预置对应的ID列表，位于ID列表中的用户ID对应的用户具有对应的操作权限。例如，可以根据每个库房的物料的种类不同，每个管理人员仅仅具有一种或多种物料的库房数据的管理权项，具体的权项分配可以根据实际需求进行合理的配置，具体此处不做限定。The node device of each warehouse can be managed by one or more administrators, and each user can be assigned a specific permission, and a corresponding ID list is preset for each operation, and the user corresponding to the user ID in the ID list is associated. Has the corresponding operation authority. For example, according to the type of materials in each warehouse, each manager only has the management right of the warehouse data of one or more materials, and the specific rights allocation can be reasonably configured according to actual needs. Not limited.
在配置好不同管理人员的权限之后，当库房的实际物料的库存量发生变化时，对应的管理人员可以根据用户ID登录节点设备，向节点设备发送更新请求，节点设备可以接收用户通过客户端发送的更新请求，该更新请求中至少包含用户ID，节点设备可以验证用户ID是否与预置的ID列表匹配，若匹配，则说明用户具有对应的操作权项，则节点设备可以接收用户的操作信息，并根据操作信息更新本地库存数据。After the permissions of different management personnel are configured, when the inventory quantity of the actual materials of the warehouse changes, the corresponding management personnel can log in to the node device according to the user ID, and send an update request to the node device, and the node device can receive the user to send through the client. An update request, the update request includes at least a user ID, and the node device can verify whether the user ID matches the preset ID list, and if the match indicates that the user has the corresponding operation right item, the node device can receive the operation information of the user. And update local inventory data based on operational information.
202、将更新之后的本地库存数据写入区块，并同步到区块链中。202. Write the updated local inventory data into the block and synchronize to the blockchain.
在节点更新本地库存数据之后，可以将更新之后的本地库存数据写入区块进行广播，使得接入区块链的节点将该最新的区块同步到区块链中，分别存储在各个节点的数据库。After the node updates the local inventory data, the updated local inventory data may be written into the block for broadcasting, so that the node accessing the blockchain synchronizes the latest block into the blockchain and stores them in each node respectively. database.
进一步的，可选的，作为一种可能的实施方式，为了提高数据的安全性，在每个库房节点设备发出广播消息进行区块链同步时，可以对广播消息中的区块进行验证。具体的，在库房节点注册时可以为每个库房节点分配对应的ID及对应的密钥；具体的服务器可以采用对称加密算法为库房节点分配密钥及 ID，或采用非对称算法为库房节点分配一个密钥对及ID，若采用对称加密算法，在对称加密算法中，数据发信方可以将明文(原始数据)和加密密钥一起经过特殊加密算法处理后，使其变成复杂的加密密文发送出去。收信方收到密文后，若想解读原文，则需要使用加密用过的密钥及相同算法的逆算法对密文进行解密，才能使其恢复成可读明文，本实施例以非对称算法分配的密钥对为例进行说明，密钥对包括公钥(Public Key)及对应的私钥(Private Key)，其中，公钥与私钥是通过一种加密算法得到的，例如：加密算法为李维斯特-萨莫尔-阿德曼(Rivest-Shamir-Adleman，简称，RSA)或数字签名算法(Digital Signature Algorithm，简称，DSA)公钥是密钥对中公开的部分，是对外公开的，私钥则是非公开的部分，是不对外公开的，需要由库房节点保存的。公钥通常用于加密会话密钥、验证数字签名，或加密可以用相应的私钥解密的数据。通过这种算法得到的密钥对能保证在世界范围内是唯一的。使用这个密钥对的时候，如果用其中一个密钥加密一段数据，必须用另一个密钥解密。比如用公钥加密数据就必须用私钥解密，如果用私钥加密也必须用公钥解密，否则解密将不会成功。在本申请实施例中，通常情况下，该公钥和私钥长度可以是256位(bit)或者以上。公钥还可以用于生成身份标识ID，ID可以是由公钥经过一定运算产生的，ID与公钥一一对应，ID可以是公钥、公钥的哈希(hash)值或者包含公钥与操作指令的一段脚本等。ID用于标识库房节点。具体来说，库房节点的ID可以由库房节点的公钥生成，和库房节点的公钥是一一对应的，并且保证是全网唯一的。具体来说，库房节点的ID可以是库房节点公钥自身，也可以是根据一个hash算法对库房节点的公钥进行hash生成的公钥hash值，还可以是包含公钥的一段脚本等多种形式，私钥为该库房节点发布的智能合约或竞价区块的签署证明，当接收到每个库房节点广播消息时，根据库房节点对应的密钥对广播消息进行解密验证，若验证通过，则将对应的广播消息中区块同步到本地存储的区块链中。Further, optionally, as a possible implementation manner, in order to improve data security, when each warehouse node device sends a broadcast message to perform blockchain synchronization, the block in the broadcast message may be verified. Specifically, each warehouse node may be assigned a corresponding ID and a corresponding key when the warehouse node is registered; the specific server may use a symmetric encryption algorithm to allocate a key and an ID to the warehouse node, or use an asymmetric algorithm to allocate the warehouse node. If a key pair and ID are symmetric encryption algorithms, in the symmetric encryption algorithm, the data sender can process the plaintext (original data) together with the encryption key through a special encryption algorithm to make it a complex encryption key. The text is sent out. After receiving the ciphertext, if the receiving party wants to interpret the original text, it needs to use the encrypted key and the inverse algorithm of the same algorithm to decrypt the ciphertext, so that it can be restored to a readable plaintext. This embodiment is asymmetric. The key pair assigned by the algorithm is described as an example. The key pair includes a public key (Public Key) and a corresponding private key (Private Key). The public key and the private key are obtained by an encryption algorithm, for example, encryption. The algorithm is a Rivest-Shamir-Adleman (RSA) or a Digital Signature Algorithm (DSA) public key, which is a public part of the key pair and is publicly disclosed. The private key is a non-public part that is not publicly available and needs to be saved by the warehouse node. Public keys are typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with the corresponding private key. The key pair obtained by this algorithm is guaranteed to be unique worldwide. When using this key pair, if one piece of data is used to encrypt a piece of data, it must be decrypted with another key. For example, encrypting data with a public key must be decrypted with a private key. If it is encrypted with a private key, it must be decrypted with a public key, otherwise the decryption will not succeed. In the embodiment of the present application, the public key and the private key may be 256 bits or more in length. The public key can also be used to generate an identity ID. The ID can be generated by a certain operation of the public key. The ID is in one-to-one correspondence with the public key. The ID can be a hash value of the public key or the public key or contain the public key. A script with an operation instruction, etc. The ID is used to identify the warehouse node. Specifically, the ID of the warehouse node can be generated by the public key of the warehouse node, and the public key of the warehouse node is in one-to-one correspondence, and the guarantee is unique to the entire network. Specifically, the ID of the warehouse node may be the public key of the warehouse node itself, or may be a public key hash value generated by hashing the public key of the warehouse node according to a hash algorithm, or may be a script including a public key. Form, the private key is the signature of the smart contract or the bidding block issued by the warehouse node. When receiving the broadcast message of each warehouse node, the broadcast message is decrypted and verified according to the key corresponding to the warehouse node, and if the verification is passed, The blocks in the corresponding broadcast message are synchronized to the locally stored blockchain.
可以理解的是，本实施例中的所示的库房节点确认广播消息有效的过程仅是示例性的，也可以采用其他具有不可逆性的算法对智能合约进行加密与验证，具体的算法，此处不做限定。It can be understood that the process of confirming that the broadcast message is valid in the illustrated warehouse node in this embodiment is merely exemplary, and other algorithms with irreversibility may be used to encrypt and verify the smart contract, the specific algorithm, here Not limited.
