it should be noted that a blockchain user needs to log in a system before using a user terminal to invoke an intelligent contract, specifically, the blockchain user needs to create in the blockchain cloud service platform first, and when the blockchain user is successfully created, a user name and a password required for logging in the system are allocated to the blockchain user. The blockchain user logs in the system after entering a user name and password in the APP of the user terminal.
After a blockchain user is created in the blockchain cloud service platform, the blockchain cloud service platform generates digital identity information for the blockchain user, wherein the digital identity information comprises a certificate and a private key, and the certificate comprises a public key, certificate issuing information and other information for proving the identity of the blockchain user.
The method comprises the steps that the corresponding relation between a user name and a password of a block chain user and digital identity information is stored in a block chain cloud service platform, when the block chain user logs in a system after inputting the user name and the password into an APP of a user terminal, the user terminal obtains the digital identity information of the block chain user in the block chain cloud service platform according to the user name and the password, encrypts the digital identity information of the block chain user and stores the encrypted digital identity information in the local.
It should be further noted that, after the blockchain cloud service platform creates the blockchain user, the blockchain cloud service platform further sets and stores access right information corresponding to the digital identity information of the blockchain user according to the identity information of the blockchain user, where the access right information includes the selectable blockchain, the selectable intelligent contracts in each selectable blockchain, the selectable methods in each selectable intelligent contract, and the invocation parameters in each selectable method. The identity information of the block chain user can be organization mechanism information of the block chain user, and if a certain organization A is a tenant of a block chain cloud service platform and the organization A has authority to access the block chains a, b and c, the block chain user of the organization A has authority to access the block chains a, b and c and has authority to call all intelligent contracts deployed in the block chains a, b and c; or the users of the blockchain of the organization a have the right to access the blockchain a, b, c, and specifically, the intelligent contracts deployed in the blockchain a, b, c and the method that each intelligent contract can call can set the access and call right according to the department or user level to which the users of the blockchain of the organization a belong.

s104: and sending the signed contract calling transaction information to the block chain cloud service platform, so that the block chain cloud service platform calls a target method in a target intelligent contract in a target block chain through a calling parameter of the target method.
It should be noted that, as the transaction is circulated, when the transaction flow is transferred to a certain blockchain user, the blockchain user may only need to invoke a method in the intelligent contract in the determined blockchain by using the determined invocation parameter, and the blockchain user does not need to make additional selection and input.
For a user terminal, when contract invoking transaction information pushed by a block chain cloud service platform is received, target block chains, target intelligent contracts, target methods and invoking parameters of the target methods in the contract invoking transaction information are displayed in a visual interface, in response to a confirmation instruction input by a block chain user through the visual interface, a private key in digital identity information of the block chain user is used for signing the contract invoking transaction information, the signed contract invoking transaction information is sent to the block chain cloud service platform, and the block chain cloud service platform invokes the target methods in the target intelligent contracts in the target block chains through the invoking parameters of the target methods.

the signature unit is used for signing the contract invoking transaction information by using a private key in the digital identity information of the block chain user;
and the contract calling transaction information sending unit is used for sending the signed contract calling transaction information to the block chain cloud service platform, so that the block chain cloud service platform calls the target method in the target intelligent contract in the target block chain through the calling parameter of the target method.
9. An intelligent contract calling device based on a visual interface is applied to a block chain cloud service platform and comprises:
the system comprises a calling request receiving unit, a calling request sending unit and a calling unit, wherein the calling request receiving unit is used for receiving an access authority information calling request which is sent by a user terminal and carries digital identity information of a block chain user;
the access authority information feedback unit is used for feeding back access authority information corresponding to the digital identity information of the users of the block chain to the user terminal according to the corresponding relation between the digital identity information and the access authority information of the users of different pre-stored block chains, so that the user terminal displays the access authority information in a visual interface, and the access authority information comprises the selectable block chains of the users of the block chain, the selectable intelligent contracts in each selectable block chain, the selectable methods in each selectable intelligent contract and the calling parameters in each selectable method;
the contract calling transaction information receiving unit is used for receiving contract calling transaction information sent by a user terminal, wherein the contract calling transaction information comprises a signature of a private key of the block chain user on the contract calling transaction information and calling parameters of a target block chain, a target intelligent contract, a target method and a target method, which are input by the block chain user through a visual interface;
the signature verification unit is used for verifying the signature, and extracting a target block chain, a target intelligent contract, a target method and a calling parameter of the target method from the contract calling transaction information after the signature passes the verification;
and the intelligent contract calling unit is used for calling the target method in the target intelligent contract in the target block chain through the calling parameter of the target method.
10. An intelligent contract calling system based on a visual interface, which is characterized by comprising:
at least one user terminal comprising the intelligent contract invoking device based on visual interface of claim 8;
a blockchain cloud service platform comprising the intelligent contract invoking device based on the visual interface of claim 9;
at least one blockchain, wherein at least one intelligent contract is deployed in each blockchain, each intelligent contract comprises at least one method, and each method comprises at least one calling parameter.
