Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.
It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.
Example 1
A block chain based service processing method applied to a uplink gateway, wherein a certificate-preserving intelligent contract is built in the uplink gateway, and referring to fig. 1, the method comprises the following steps:
step S101, acquiring service definition content of uplink service input by a service system, distributing an identity for the service system, and generating a corresponding account address and an access key.
In the step, after the service system performs service definition in the uplink gateway, the uplink gateway does not distribute an account address and an access key to the service system after acquiring service definition content, wherein the account address is used for indicating an object needing to perform uplink service, namely, the uplink gateway can obtain an object storing uplink data through inquiring the account address; the access key refers to a private key that encrypts the uplink data. In the step, a service definition template is created in the uplink gateway, and service definition contents are recorded, so that the follow-up certificate-storing intelligent contract can automatically acquire data required by the service definition contents.
Step S102, deploying the certificate-storing intelligent contract for the uplink service and generating a contract address, wherein the certificate-storing intelligent contract automatically acquires the service definition content and acquires the uplink data to be stored from the service definition content to construct parameter information of an online API interface.
In the step, the up-link gateway is internally provided with a certificate-storing intelligent contract and can automatically deploy up-link data for a service system. Specifically, a contract address, an account address, an access key and the like related to the certificate storing intelligent contract are built-in parameters of the uplink system. When the service system wants to store data as chain nodes of the blockchain, the blockchain allocates account addresses for the service system, and the data is stored in a storage position when being uplinked, wherein the storage position refers to a contract address. The intelligent contract can automatically acquire the uplink data to be stored from service definition content, and takes the uplink data as a body parameter for constructing an online API interface, wherein the body parameter of the interface is data which is input when a service system defines and is used for telling an uplink gateway to be stored on a link node.
The difference of the steps is that the certificate storing intelligent contract is built in the uplink gateway, when a service system needs to initiate uplink service, the chain application development side does not need to access the SDK, and only needs to input service definition content into the uplink gateway according to a service template which is required to be read by the certificate storing intelligent contract. What the upstream gateway builds from the acquired service definition content is the rules of the interface itself, such as the HTTP protocol, which can be invoked using a variety of development languages. Compared with the block chain SDK which is needed to be used in the block chain technology, the block chain SDK initialization and the verification intelligent contract knowledge are carried out, the block chain SDK is directly shielded, the block chain SDK initialization and the block chain SDK integration and the verification intelligent contract knowledge are carried out, and therefore the access difficulty is greatly reduced.
And step S103, creating an online API interface based on the parameter information, calling the online API interface, and uploading the uplink data to be stored through the access key encryption and then the certificate.
In this step, the parameters configuring the online API interface include: the system comprises an interface address, an interface header parameter, an interface body parameter and a return parameter, wherein the interface address and the interface header parameter are fixed, a plurality of interfaces can be used in common, the interface body parameter is recorded by a service system when a service is defined, and the interface body parameter comprises uplink data which need to be stored and is used for telling a uplink gateway of the content to be uplink of the current uplink service.
As shown in fig. 2, in the technical scheme of the invention, the uplink gateway system shields the blockchain access development, the data uplink development, the data query development, the intelligent contract development and the like related to the data uplink process, converts the development processes into the common HTTP interface development, and the link application end can complete the blockchain access only by carrying out the service data configuration on the uplink gateway and complete the data uplink and the subsequent data query through calling the interface.
Aiming at the steps S101 to S103, in the embodiment of the application, the certificate intelligent contract is built in the uplink gateway, the certificate intelligent contract is automatically configured for the service when the uplink service is acquired, the parameter information required by the interface is acquired to develop an online API interface, and the certificate of the required stored data is linked up by calling the interface, so that the difficulty of block link-in is reduced.
In other embodiments, the authenticated smart contract has defined internally a contract send address, a contract receive address, contract authentication content, an uplink transaction hash, and a transaction time.
In this embodiment, the parameter information related to the certificate storing intelligent contract is built in the uplink gateway, and the sending address and the receiving address of the contract can be automatically obtained by calling the certificate storing intelligent contract, so that the certificate storing content, the uplink transaction hash and the transaction time, that is, the uplink gateway automatically processes the required stored data in the data uplink process. The uplink gateway acquires service definition content input by the link application end, an interface for data uplink is automatically created, and the link application end can complete a service uplink process only by calling a corresponding online API interface.
In some embodiments, the service definition content includes a service name, a service description, and a service uplink encryption type, wherein the access key is determined by the service uplink encryption type.
In this embodiment, the encryption type may be determined according to the blockchain platform, for example, the encryption type is not encryption, national encryption 2, national encryption 3, national encryption 4, and so on. And the uplink gateway generates an access key according to the service uplink encryption type selected by the service system.
In some of these embodiments, the method further includes generating an online interface document of the online API interface from a built-in interface document template, the online interface document comprising: and calling address, calling mode, calling parameters and calling result return parameters, and carrying out calling development work on the online API according to the online interface document.
In this embodiment, the HTTP call parameter includes an identity parameter, a service data field, and a field data type, where the identity refers to appid, appsecret and a service number uuid that are automatically allocated to the uplink service after the uplink gateway enables the service definition content, and the identity is used to perform authentication when calling the online API interface. And extracting the interface appid, appsecret, comparing and verifying the service number uuid with the stored information during verification, and processing the service request passing verification by the online API interface to return the data required by the service.
In some of these embodiments, the online API interface comprises a ul interface; and the uplink port is used for encrypting the uplink data to be stored through the access key and then uploading the encrypted authentication.
In this embodiment, the data structure of the acquired uplink data is as follows:
{ "app id": "identity id",
"appsecret": an "identification key",
"business_name": "service name",
"business_desc": "service description",
"stats": "status",
"secret_type": "encryption type",

},{
"data_name": "field name",
"data_type": "data type",
"data_length": "data length",
"data_descriptor" data description "
}]
}
After encryption by the access key, the final certificate uplink data structure is formed as follows:
{"appid":"LKeuGr84",
"appsecret":"65a4964eb7b68347bae3a9b7da85c7e30f1aa576",

"contract_address":"0xfaf899c36c72c9d3b5710f2575c9256b86bcc27d"，

},{
"data_name":"operator_time",
"data_type":"string",
"data_length":"50",
"data_descriptor" operation time yyyy-MM-dd HH: MM: ss "
}]
}
The uplink gateway constructs a uplink interface according to the data interface parameter information, wherein an interface address of the uplink interface is composed of an interface fixed address and a service number, for example, a request fixed path is/blockchain/gateway/api, a request service number { uuid }, and the obtained interface address is/blockchain/gateway/api/{ uuid }. The request header parameters of the ul interface include appid, appsecret. The request body parameter information of the uplink interface comprises field name attribute of each data object in the extracted service definition content, and the field name attribute is respectively constructed into request parameters in form and request parameters in JSON format.
In addition, two business demands of synchronous uplink and asynchronous uplink are provided in the uplink gateway, the synchronous uplink is a real-time uplink, the synchronous uplink directly returns the uplink transaction hash to the business system, the asynchronous uplink does not return the uplink transaction hash, only the uplink data number is returned, and the business system can inquire the uplink transaction hash according to the acquired data number after the uplink is completed.
Specifically, as shown in fig. 3, the uplink port includes a synchronous uplink interface and an asynchronous uplink interface, where the synchronous uplink port is used for real-time uplink and returning to the uplink transaction hash corresponding to the uplink service, and the asynchronous uplink port returns a digital number.
In this embodiment, the specific steps of adopting the synchronous uplink port data uplink are as follows: when a service system initiates a data uplink call, the uplink gateway firstly performs interface authentication verification, extracts interface appid, appsecret and service number uuid parameters for comparison verification, obtains service definition content according to the service number uuid after verification, sequentially extracts the service definition content from request body parameters according to a data structure of the service definition, generates a data number for the data submitted by the call to mark the submitted uplink data, obtains uplink account information and intelligent contract information from the service definition according to the uplink service number, constructs block chain transaction information, invokes a block chain transmission transaction method, transmits the transaction information to a block chain platform, receives a return result, analyzes transaction hash in the result and returns the data number and the uplink transaction hash. The method adopts the specific steps of asynchronous uplink port data uplink as follows: after the authentication and verification are passed, the extracted data, service definition and data number are packaged together and put into a buffer queue for processing by an interface data uplink and generating a data number for the data submitted by the call to mark the uplink data submitted this time, only the data number is returned, the service system needs to record the data number returned by the step, and a transaction hash inquiry interface is additionally adopted to inquire the uplink transaction hash.
In some of these embodiments, the online API interface further comprises a uplink data query interface and a transaction hash query interface; the uplink data query interface is used for acquiring the uplink data according to the input uplink transaction hash; the transaction hash inquiry interface is used for acquiring the uplink transaction hash corresponding to the uplink service according to the input data number.
In this embodiment, the uplink gateway may also automatically create a uplink query interface and a transaction hash query interface, when the asynchronous interface is invoked, the interface only returns a data number to the service system, at this time, the service system may query the transaction hash by invoking the query interface and inputting parameters such as the data number, the service number, appid, appsecret, etc., the uplink gateway will perform interface authentication verification, extract the interface appid, appsecret and the service number uuid parameters to perform comparison verification, and query the uplink transaction hash according to the data number through the verified request, and the service system records the queried uplink transaction hash. The uplink query interface inputs the uplink port hash, and inputs the service number and appid, appsecret for comparison and verification. And the verification is that the back uplink gateway invokes the blockchain query interface to initiate a query request to the blockchain platform and returns a query result, wherein the query result comprises block-containing hash, block height, transaction information, transaction address, transaction time and the like.
In summary, in order to solve the problem that the current application system needs to use a blockchain SDK, an intelligent contract language and an access technology difficulty brought by an intelligent contract writing rule at a time chain application development side (a service system) of an access blockchain platform of the application system, the intelligent contract is stored in a linking gateway, a contract sending address, a contract receiving address, a contract storing content, a transaction hash and a transaction time are defined in the intelligent contract, and the linking gateway can automatically generate a blockchain account address and an encryption key for the service system and automatically deploy the intelligent contract storing and generate a contract address for the service system. The intelligent contract and the block chain automatic processing are realized by the built-in certificate, so that the service system can realize the technology of data uplink and data query only by calling an interface. Compared with the prior art, the chain application development side does not need to access the SDK, does not need to know the blockchain, only needs to know how to call the HTTP Restful interface, and records the data number returned by the uplink data and the transaction hash at the same time, thereby reducing the development difficulty and simplifying the complexity of accessing the blockchain platform.
