in the embodiment of the present invention, the client may run on the terminal in fig. 1; the service identification information of the target service data described in the embodiment of the present invention may be understood as identification information for distinguishing the target service data from other data, and the identification information may be a name of the target service data or type information of the target service data, or the like. The target service data refers to data which needs to be returned to the client.
Step S202: determining a data return type task corresponding to the service request according to the service identification information;
in the embodiment of the present invention, the data return type task may be understood as a task that needs to return data to the client, that is, a task that requests main function data corresponding to the service request.
Specifically, the electronic device queries each processing task corresponding to the service request according to the service request, distinguishes each processing task corresponding to the service request according to the service identification information, obtains a processing task matched with the service identification information, and determines the processing task matched with the service identification information as a data return type task.

here, the target blockchain node may be any one or more blockchain nodes in the blockchain, or may be one or more blockchain nodes satisfying a preset condition.
Step S204: and when the target service data returned by the target block chain node is received, returning the received target service data to the client.
Specifically, the electronic device sends a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task, the target blockchain node queries a corresponding account book in local storage data of the target blockchain node, decrypts the content of the account book to obtain target service data, and returns the obtained target service data to the electronic device, and when receiving the target service data returned by the target blockchain node, the electronic device returns the received target service data to the client.
In the block chain-based service request response method, after a service request sent by a client is obtained, a data return type task corresponding to the service request is determined according to service identification information of target service data carried in the service request, a data query instruction is sent to a target block chain node according to the data return type task and is used for indicating the target service data queried and returned by the target block chain node, and when the target service data returned by the target block chain node is received, the received target service data is immediately returned to the client, so that the target service data is returned to the client after the tasks of other types are completely processed, and the waiting time of a user can be reduced.
In one embodiment, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may include: and taking the block chain link point with the closest communication distance in the pre-established block chain as the target block chain node, and sending a data query instruction to the target block chain node according to the data return type task.
After receiving the data query instruction, the target block link node may query and return the target service data in the local storage data of the target block link node according to the carried service identification information, the identification information of the data return type task, or the data return type task.
Specifically, the IP (Internet Protocol) address information corresponding to the electronic device may be acquired, the IP address information corresponding to the electronic device is compared with IP address information corresponding to each block link point in the block chain, a block link point with a closest communication distance is determined according to a comparison result, the operation may be performed after the block chain is established or only performed once when the block chain is updated, and after a block link point with a shortest communication distance to the client is determined, the operation is recorded until the block chain is updated again, and the block link point with the closest communication distance is determined again. The updating of the block chain refers to newly adding a block chain node or reducing a block chain node. The communication distance can be determined based on the IP address information in any realizable manner.
In this embodiment, the data query instruction is sent to the target block chain node in the pre-established block chain according to the data return type task, so that the sending time of the data query instruction and the receiving time of the target service data can be saved, and the waiting time of the user can be further reduced.
In one embodiment, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may further include: and when the target block chain link does not inquire the target service data in the local storage data, taking the block chain node connected with the current target block chain link as a new target block chain link, and returning to the step of sending a data inquiry instruction to the target block chain node according to the data return type task. Specifically, as shown in fig. 3, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may include:
step S301: taking a block chain link point with the closest communication distance in a pre-established block chain as a target block chain node;
step S302: sending a data query instruction to a target block link node according to the data return type task;
step S303: and when the current target block chain node does not inquire the target service data in the local storage data, taking the block chain node connected with the current target block chain link as a new target block chain link, and returning to the step S302.
Here, the connected block chain node refers to a block link point directly connected to a target block link point in the same block chain. It should be understood by those skilled in the art that the current target blockchain node may be, but is not limited to, the blockchain node having the shortest communication distance with the client. For example, the block chain node having the shortest communication distance with the client is a block link point k, the block chain node connected to the block link point k is a block link point k +1, the block chain node connected to the block link point k +1 is a block link point k +2, and so on. When the block link point k does not inquire the target service data in the local storage data of the block link point k, sending the data inquiry command to a block link point k +1, wherein the current target block link node at this time is the block link point k, namely, the block link node having the shortest communication distance with the client, and when the block link point k +1 does not inquire the target service data in the local storage data of the block link point k +1, sending the data inquiry command to a block link point k +2, wherein the current target block link node at this time is the block link point k + 1.
If the target block link does not inquire the target service data in the local storage data, the identification information of the connected block link node of the target block link can be returned to the electronic device, and when the electronic device receives the identification information, the connected block link node of the target block link is used as a new target block link according to the identification information.
In this embodiment, when the current target block chain node does not inquire the target service data in the local storage data, the target service data can also be inquired through the block chain node connected to the target block chain link, so that the target service data can be inquired as quickly as possible.
In one embodiment, as shown in fig. 4, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may include:
step S401: sequencing each block chain link point in a pre-established block chain according to the communication distance to obtain a sequencing result;
here, the communication distance is a communication distance between each block link point and the electronic device. Specifically, the link points of each block can be sorted according to the communication distance from small to large to obtain a sorting result.
Step S402: sequentially selecting one block chain node as a target block chain node according to the sequencing result in the sequence from small communication distance to large communication distance;
step S403: sending a data query instruction to a currently selected target block chain node according to the data return type task;
step S404: and when the currently selected target block link does not inquire the target service data in the local storage data, selecting the next block link node as a new target block link node according to the sorting result, and returning to the step S403.
When the target service data is not inquired in the local storage data by the blockchain node with the first small communication distance, the next blockchain node is the blockchain node with the second small communication distance, and when the target service data is not inquired in the local storage data by the blockchain node with the second small communication distance, the next blockchain node is the blockchain node with the third small communication distance, and so on.
By adopting the scheme in the embodiment, the communication delay can be reduced as much as possible. In addition, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may further include: and when the current task processing capacity of the current target block chain link exceeds a preset threshold value, selecting a next block chain node as a new target block chain link point according to the sorting result, taking a block chain node connected with the current target block chain link as a new target block chain link, and returning to the step of sending a data query instruction to the target block chain node according to the data return type task.
By adopting the scheme in the embodiment, the task allocation can be prevented from being too concentrated, and the waiting time of the user can be further reduced.
In one embodiment, the sending a data query instruction to a target blockchain node in a pre-established blockchain according to the data return type task may further include: and when the target block chain link does not inquire the target service data in the local storage data, taking the connected block chain node of the current target block chain link as a new target block chain link, and forwarding the data inquiry command to the new target block chain link by the current target block chain link.
By adopting the scheme in the embodiment, information does not need to be fed back to the electronic device, and communication delay can be reduced.
In one embodiment, when there are a plurality of target blockchain nodes, the returning the received target service data to the client when receiving the target service data returned by the target blockchain node may include: and receiving the target service data returned by each target block chain node, and returning the target service data received firstly to the client.
In this embodiment, a plurality of target blockchain nodes are provided, the target service data returned by each target blockchain node is received, and the target service data received first is returned to the client, so that the waiting time of the user can be reduced as much as possible.
In one embodiment, as shown in fig. 5, a block chain based service request response method is provided, which is described by taking the method as an example applied to the electronic device in fig. 1, and includes the following steps:
step S501: acquiring a service request sent by a client, wherein the service request carries service identification information of target service data;
step S502: determining a data return type task corresponding to the service request according to the service identification information;
step S503: sending a data query instruction to a target block chain node in a pre-established block chain according to the data return type task, wherein the data query instruction is used for indicating the target block chain node to query and return the target service data in local storage data;

step S505: determining the non-data return type tasks corresponding to the service request according to the service identification information, and counting the number of the non-data return type tasks;
step S502 and step S505 may not be executed in the above-mentioned order, or may be executed simultaneously.
The non-data-return type task may be understood as a task that does not need to return data to the client, that is, a processing task corresponding to an attached function of the service request, for example, some tasks that only need to perform data storage or data calculation locally at the server.
Specifically, each processing task corresponding to the service request may be determined according to the service request, each processing task corresponding to the service request may be distinguished according to the service identification information, a processing task matched with the service identification information is obtained, the processing task matched with the service identification information is determined as a data return type task, and the remaining processing tasks except the data return type task in each processing task corresponding to the service request are determined as non-data return type tasks.
Step S506: and after the target service data is returned to the client, distributing the non-data-return tasks to the number of block chain link points in the block chain for parallel processing.
In this embodiment, the non-data-return task is distributed to the number of block link points in the block chain to be processed in parallel, so that the processing efficiency can be improved. Meanwhile, after the target service data is returned to the client, the non-data-return tasks are distributed to the block chain link points of the number in the block chain for parallel processing, so that the influence on the processing process of the data-return tasks can be avoided.
However, the distribution method of the non-data-return type task is not limited to such an average distribution method, and for example, the non-data-return type task may be collectively distributed to one or more blockchain nodes to be processed.
In one embodiment, the distributing the non-data-return task to the number of block link points in the block chain for parallel processing may include: sending task processing instructions to the block chain nodes of the number, wherein each task processing instruction carries one non-data-return task, and the task processing instructions are used for indicating the block chain nodes receiving the task processing instructions to process the non-data-return tasks carried in the task processing instructions and distribute obtained local processing results to the block chain; and sending a data summarizing instruction to each block chain node in the block chain nodes, wherein the data summarizing instruction is used for indicating each block chain node to summarize and store the local processing result of the received task processing instruction.
After the non-data-return task is distributed to the blockchain nodes, the blockchain nodes which process the non-data-return task distribute local processing results to the blockchain, and the local processing results of the blockchain nodes which process the non-data-return task are collected and stored by all the blockchain nodes in the blockchain.
For example, for a block chain including a block chain node 1, a block chain node 2, a block chain node 3, a.... and a block chain node n, there are m non-data-return tasks, the non-data-return tasks may be distributed to the m block chain nodes in the block chain according to some preset rules or randomly, each block chain node processes one non-data-return task, and the m block chain nodes processing the non-data-return tasks respectively distribute respective local processing results to the block chain. Then, n block chain link points in the block chain are summarized respectively according to the local processing results distributed by the m block chain nodes for processing the non-data return task, and the summarized results are stored in respective local storage data. Generally, the summary results are collected into an account book for storage, the account book is encrypted before the summary, and the encrypted account book is stored.
In one embodiment, the non-data-return tasks include data computation tasks and data preservation tasks; the method comprises the steps that a block chain link point receiving a task processing instruction carrying a data storage task obtains target storage data corresponding to the received data storage task, and the obtained target storage data are distributed to a block chain; and calculating the corresponding data of the received data calculation task by the block chain link point which receives the task processing instruction carrying the data calculation task to obtain a local calculation result, and sending the obtained local calculation result to the block chain.
In one embodiment, the method for responding to a service request based on a block chain of the present invention may further include: and transferring the non-data-return task from the main thread where the data-return task is located to a task queue in an asynchronous operation mode, and processing the non-data-return task in the task queue after the block link node receiving the data query instruction returns the target request data to the client.
Wherein processing the non-data-return task in the task queue may include: and distributing the non-data return tasks to the number of block chain link points in the block chain for parallel processing.
According to the scheme of the embodiment, the non-data return type task is moved to the task queue from the main thread where the data return type task is located, so that the rest tasks in the main thread can be processed and completed as soon as possible, and the waiting time of a user is shortened.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
