1. A method for data query, the method comprising:
responding to a data query request, and acquiring data to be queried, which comprises one or more json character strings, according to the data query request;
performing field analysis on each json character string in the data to be queried to obtain a query field corresponding to each json character string;
determining an interface field corresponding to each query field according to preset mapping relation data of the query fields and the interface fields;
acquiring interface parameter information of an application interface corresponding to each interface field, and constructing an interface calling request according to the interface parameter information and all the interface fields corresponding to the interface parameter information;
calling the application interface according to the interface calling request, and receiving an interface return value of the application interface to perform data replacement on the data to be queried to obtain queried data;
and sending the query data to the terminal equipment sending the data query request and/or predetermined terminal equipment.
2. The data query method of claim 1, wherein the performing field parsing on each json character string in the data to be queried to obtain a query field corresponding to each json character string comprises:
and extracting the key name of each key value pair in the json character string to obtain a query field corresponding to the json character string.
3. The data query method of claim 1, wherein the receiving an interface return value of the application interface to perform data replacement on the data to be queried to obtain query data comprises:
extracting a return value corresponding to the interface field in the interface return value to obtain a field return value of the interface field;
determining the field return value of the interface field as the field query value of the query field corresponding to the interface field;
determining the key name in the json character string as the key value pair of the query field as a target key value pair of the query field;
and replacing the field query value of the query field with the key value in the target key value pair corresponding to the query field in the data to be queried to obtain the query data.
4. The data query method of claim 3, wherein the replacing the field query value of the query field with a key value in a target key value pair corresponding to the query field in the data to be queried to obtain the query data includes:
acquiring a field value format corresponding to the query field;
converting the field query value of the query field into a field value format corresponding to the query field;
and replacing the field query value of the query field after format conversion with a key value in a target key value pair corresponding to the query field in the data to be queried to obtain the query data.
5. The data query method according to claim 1, wherein the sending the query data to the terminal device that issued the data query request and/or a predetermined terminal device comprises:
converting the query data into a preset data format to update the query data;
and sending the updated query data to the terminal equipment which sends the data query request and/or the predetermined terminal equipment.
6. The data query method according to any one of claims 1 to 5, wherein the sending the query data to the terminal device that issued the data query request and/or a predetermined terminal device includes:
calculating a data signature of the query data;
identifying the query data using the data signature;
and sending the query data identified by the data signature to the terminal equipment sending the data query request and/or predetermined terminal equipment.
7. A data query apparatus, comprising:
the field analysis module is used for responding to a data query request and acquiring data to be queried, which comprises one or more json character strings, according to the data query request; performing field analysis on each json character string in the data to be queried to obtain a query field corresponding to each json character string; determining an interface field corresponding to each query field according to preset mapping relation data of the query fields and the interface fields;
the data query module is used for acquiring interface parameter information of the application interface corresponding to each interface field and constructing an interface calling request according to the interface parameter information and all the interface fields corresponding to the interface parameter information; calling the application interface according to the interface calling request, and receiving an interface return value of the application interface to perform data replacement on the data to be queried to obtain queried data;
and the data sending module is used for sending the query data to the terminal equipment which sends the data query request and/or predetermined terminal equipment.
8. The data query apparatus of claim 7, wherein the receiving of the interface return value of the application interface to perform data replacement on the data to be queried to obtain query data comprises:
extracting a return value corresponding to the interface field in the interface return value to obtain a field return value of the interface field;
determining the field return value of the interface field as the field query value of the query field corresponding to the interface field;
determining key names in the json character strings as key value pairs of the query fields as target key value pairs of the query fields;
and replacing the field query value of the query field with the key value in the target key value pair corresponding to the query field in the data to be queried to obtain the query data.
9. An electronic device, characterized in that the electronic device comprises:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor;
wherein the memory stores a computer program executable by the at least one processor, the computer program being executable by the at least one processor to enable the at least one processor to perform the data query method of any one of claims 1 to 6.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out a data query method according to any one of claims 1 to 6.
