Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent 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 certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Example one
A service processing method based on a block chain is applied to an uplink gateway, where the uplink gateway has a built-in intelligent contract for evidence storage, and with reference to fig. 1, the method includes:
step S101, acquiring the business definition content of the uplink business recorded by the business system, distributing the identity for the business system and generating the corresponding account address and the access key.
In this step, after the service system performs service definition in the uplink gateway, the uplink gateway does not allocate an account address and an access key to the service system after acquiring the service definition content, where the account address is used to indicate an object that needs to perform uplink service, that is, an object storing uplink data can be obtained by querying the account address in the uplink gateway; the access key refers to a private key that encrypts uplink data. In the step, the service definition template is created in the uplink gateway, and the service definition content is input, so that the subsequent deposit-evidence intelligent contract can automatically acquire the required data in the service definition content.
Step S102, the intelligent contract for upper chain service is deployed and a contract address is generated, and the intelligent contract for upper chain service automatically acquires the service definition content and acquires upper chain data required to be stored from the service definition content to construct parameter information of an online API.
In this step, the uplink gateway is provided with a built-in evidence-storing intelligent contract and can automatically deploy uplink data for the service system. Specifically, contract addresses, account addresses, access keys and the like related to the certified intelligent contracts are built-in parameters of the uplink system. When the service system wants to store data in a chain node of the block chain, the block chain allocates an account address for the service system, and a storage location is needed when the data is stored in the uplink, wherein the storage location refers to a contract address. The intelligent contract can automatically obtain the uplink data required to be stored from the service definition content, and the uplink data is used as the body parameter for constructing the online API interface, wherein the body parameter of the interface is the data which is recorded during the service system definition and is used for telling the uplink gateway to store the uplink data on the link point.
The difference of this step is that the intelligent contract for storing evidence is built in the uplink gateway, when the service system needs to initiate uplink service, the chain application development side does not need to access the SDK, and only needs to input the service definition content into the uplink gateway according to the service template that needs to be read by the intelligent contract for storing evidence. The on-line API interface built by the uplink gateway according to the retrieved service definition content is related to 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 technology in which the block chain SDK is needed to be used for block chain SDK initialization and evidence-storing intelligent contract learning, the block chain SDK initialization and block chain SDK initialization are directly shielded in the step, and the block chain SDK integration and evidence-storing intelligent contract learning method greatly reduces the access difficulty.
Step S103, an online API interface is established based on the parameter information, and the online API interface is called to encrypt the uplink data to be stored through the access key and then store the chain.
In this step, configuring parameters of the online API interface includes: the interface address, interface header parameter, interface body parameter and return parameter, wherein the interface address, interface header parameter are fixed, a plurality of interfaces can be common, the interface body parameter is recorded by the service system when the service is defined, the interface body parameter includes the uplink data required to be stored, and is used for telling the uplink gateway the content to be uplink of the uplink service.
As shown in fig. 2, in the technical solution of the present invention, a uplink gateway system shields block link access development, data uplink development, data query development, intelligent contract development, and the like involved in a data uplink process, converts these development processes into general HTTP interface development, and a link application end only needs to perform configuration of service data on the uplink gateway to complete access to a block link, and completes data uplink and subsequent data query by calling an interface.
For the above steps S101 to S103, in the embodiment of the present application, a certificate storing intelligent contract is built in the uplink gateway, when acquiring the uplink service, the certificate storing intelligent contract is automatically configured for the service, and parameter information required by the interface is acquired to develop the online API interface, and the certificate storing uplink of the data to be stored is completed by calling the interface, so that the difficulty of block link entry is reduced.
In other embodiments, the intelligent contract for deposit evidence internally defines a contract sending address, a contract receiving address, contract deposit evidence content, a chain transaction hash, and a transaction time.
In this embodiment, the parameter information related to the intelligent contract for storing certificates is embedded in the uplink gateway, and the sending address, the receiving address, the contract storing certificate content, the uplink transaction hash and the transaction time of the contract can be automatically obtained by calling the intelligent contract for storing certificates, that is, the uplink gateway automatically processes the data to be stored in the data uplink process. And the chaining gateway acquires the service definition content recorded by the chain application end, automatically creates an interface for chaining data, and the chain application end can complete the service chaining process only by calling the corresponding online API interface.
In some of these embodiments, the service definition content includes a service name, a service description, and a service uplink ciphering type, wherein the access key is determined by the service uplink ciphering type.
In this embodiment, the encryption type may be determined according to the blockchain platform, for example, the encryption type is unencrypted, country secret 2 encryption, country secret 3 encryption, country secret 4 encryption, and the like. And the uplink gateway generates an access key according to the service uplink encryption type selected by the service system.
In some embodiments, the method further comprises generating an online interface document for the online API interface from a built-in interface document template, the online interface document comprising: calling an address, a calling mode, a calling parameter and a calling result return parameter, and calling and developing 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 an apid, appexecute, and a service number uuid automatically allocated to an uplink service after the uplink gateway enables service definition content, and the identity is used for authentication verification when calling an online API interface. And during verification, the interfaces appid, appsecret, the service number uuid are extracted and compared with the stored information for verification, and the online API interface processes the service request passing the verification and returns the data required by the service.
In some of these embodiments, the online API interface comprises an uplink interface; the uplink interface is used for storing the uplink data to be stored after being encrypted by the access key.
In this embodiment, the data structure of the acquired uplink data is as follows:
{ "approximate": identity id ",
appsecret: "identity key",
"business name",
"business _ desc": service description ",
"stats": status ",
"secret _ type": encryption type ",
"uuid" means "service number",
"account": contract account ",

"data _ descriptor" data description "
},{
"data _ name": field name ",
"data _ type": data type ",
"data _ length": data length ",
"data _ descriptor" data description "
}]
}
An example of the data structure of the final certified uplink formed after encryption by the access key is as follows:
{"appid":"LKeuGr84",
"appsecret":"65a4964eb7b68347bae3a9b7da85c7e30f1aa576",
"business _ name": system oplog uplink ",

"contract_address":"0xfaf899c36c72c9d3b5710f2575c9256b86bcc27d"，

"data_name":"username",

},{
"data_name":"operators",
"data_type":"string",

},{
"data_name":"operator_time",
"data_type":"string",
"data_length":"50",
"data _ descriptor" operation time yyyy-MM-dd HH: MM: ss "
}]
}
The uplink gateway constructs an uplink interface according to the data interface parameter information, wherein an interface address of the uplink interface consists of an interface fixed address and a service number, for example, a request fixed path is/block/gateway/api, a request service number { uuid }, and an obtained interface address is/block/gateway/api/{ uuid }. The request header parameters of the uplink interface include appid and appsecret. The request body parameter information of the uplink interface comprises the field name attribute of each data object in the extracted service definition content, and is respectively constructed into a request parameter in a form of a form and a request parameter in a JSON format.
In addition, two service requirements of synchronous uplink and asynchronous uplink are provided in the uplink gateway, the synchronous uplink is real-time uplink and directly returns uplink transaction hash to the service system, the asynchronous uplink does not return uplink transaction hash and only returns uplink data number, and the service 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 interface includes a synchronous uplink interface and an asynchronous uplink interface, wherein the synchronous uplink interface is used for real-time uplink and returns a uplink transaction hash corresponding to the uplink service, and the asynchronous uplink interface returns a numerical number.
In this embodiment, the specific steps of using the synchronous uplink interface data uplink are as follows: when a business system initiates data uplink calling, an uplink gateway firstly performs interface authentication verification, extracts interface appid, appseret and service number uuid parameters for comparison verification, acquires business definition contents according to the service number uuid after verification, sequentially extracts the business definition contents from request body parameters according to a data structure of business definition, generates a data number for the data submitted by the calling to mark the uplink data submitted at this time, acquires uplink account information and intelligent contract information from the business definition according to the uplink service number, constructs block chain transaction information according to the encryption type of the uplink data, calls a block chain to send a transaction method, sends the transaction information to a block chain platform, receives a return result, analyzes the transaction hash in the result and returns the data number and uplink transaction hash. The specific steps of employing the asynchronous uplink interface for data uplink are as follows: after the authentication verification is passed, the extracted data, the service definition and the data number are packed together and put into a cache queue for the interface data uplink to process, a data number is generated for the data submitted by the calling to mark the uplink data submitted this time, only the data number is returned, the service system needs to record the data number returned in the step, and additionally adopts a transaction hash inquiry interface to inquire the uplink transaction hash.
In some of these embodiments, the online API interface further comprises an uplink data query interface and a transaction hash query interface; wherein, the uplink data inquiry 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 further automatically create an uplink inquiry interface and a transaction hash inquiry interface, when the asynchronous interface is called, the interface only returns a data number to the service system, at this time, the service system may input parameters such as the data number, the service number, the appid, the appseret, and the like to inquire the transaction hash by calling the inquiry interface, the uplink gateway performs interface authentication verification, extracts parameters such as the interface appid, the appseret, and the service number uuid to perform comparison verification, inquires the uplink transaction hash according to the data number by a verification request, and records the inquired uplink transaction hash. And the uplink inquiry interface inputs the uplink interface hash, and inputs the service number, the appid and the appsecret for comparison and verification. And after the verification is passed, the uplink gateway calls the block chain inquiry interface to initiate an inquiry request to the block chain platform and returns an inquiry result, wherein the inquiry result comprises a block hash, a block height, transaction information, a transaction address, transaction time and the like.
In summary, in the embodiments of the present application, to solve the problem that the access technology difficulty is large due to the fact that a chain application development side (service system) needs to use a block chain SDK, an intelligent contract language, and an intelligent contract compiling rule when an application system is accessed to a block chain platform at present, a deposit-certificate intelligent contract is built in an uplink gateway, a contract sending address, a contract receiving address, contract deposit-certificate content, a transaction hash, and transaction time are defined in the deposit-certificate intelligent contract, and the uplink gateway can automatically generate a block chain account address for the service system, encrypt a key, and automatically deploy a deposit-certificate intelligent contract for the service system and generate a contract address. The technology of data chaining and data query can be realized by a service system only by calling an interface through the built-in memory-evidence intelligent contract and the block chain automatic processing. Compared with the prior art, the chain application development side does not need to access the SDK, does not need to solve the block chain, only needs to know how to call the HTTP Restful interface, and records the data number and the transaction hash returned by the uplink data, so that the development difficulty is reduced, and the complexity of accessing a block chain platform is simplified.
