The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like. The memory 120 is used for storing a program, and the processor 130 executes the program after receiving the execution instruction.
The processor 130 may be an integrated circuit chip having signal processing capabilities. The Processor may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps, and logic blocks disclosed in the embodiments of the present application may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a parameter checking method, where the parameter checking method is applied to the data processing apparatus 100 shown in fig. 1, and the data processing apparatus 100 may be, but is not limited to, a smart phone, a Personal Computer (PC), a tablet computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like. The individual steps of the method are explained in detail below.
And S100, acquiring an operating parameter in the Hbase database operating instruction, wherein the operating parameter is a byte type array.
Optionally, the data processing device 100 obtains an operation instruction for the Hbase database, and analyzes the operation instruction according to a grammar rule of the operation instruction for the Hbase database, so as to obtain an operation parameter therein.
For example, in one possible example, the operation instruction is "create 'student _ info'," contacts ', "address'. The function of the operation instruction is to establish a table called "student _ info" in the Hbase database, wherein the table comprises two column families, namely "contacts" and "address" respectively; "create" is an operation function of the operation instruction, and is a keyword in the Hbase database. In this way, the data processing apparatus 100 obtains the operation parameters according to the syntax rules corresponding to different operation instructions.
And step S200, converting the operation parameters into an array of char types.
And S300, sequentially reading the data in the char type array, converting the data into integers, and comparing the integers with the Unicode coding range.
Optionally, the operation parameters acquired by the data processing apparatus 100 are an array of byte types in Java. The data length of each datum in the byte type array is 8 bits, and the Unicode encoding of Chinese characters is 16 bits in length. To determine the encoding of each character in the operating parameter, the 8-bit byte array needs to be converted into a 16-bit char array.
For example, in one possible example, a table is created in the Hbase database, named "student info _ name", stored in a byte type array, named "qualifield name". After the data processing device 100 obtains the table name, the byte type array is converted into a char type array by the following codes:
char arr＝new String(qualifierName).toCharArray()；
the method comprises the steps of creating an anonymous String object by taking 'qualiferenme' as a parameter, calling a 'toCharAlrraray ()' method of the object, and converting the String object into an array of char types. The data processing device 100 sequentially converts the data in the char type array into integers and compares the integers with the encoding range of preset characters, wherein the preset character types include preset english characters, preset symbolic characters and chinese characters. For example, the data processing apparatus 100 converts char type "learning" into an integer, and compares the integer with the Unicode range of english characters, the encoding range of preset symbol characters, and the encoding range of chinese characters in this order.
And step S400, if the integers corresponding to the data are all located in the Unicode encoding range, executing a corresponding operation instruction according to the operation parameters.
After the data processing device 100 checks the operation parameters, if the characters in the operation parameters all belong to legal characters of preset english characters, preset symbolic characters and chinese characters, corresponding operation instructions are executed according to the operation parameters, and a corresponding data table of chinese names is created in the Hbase database. If the operation character contains illegal characters, such as "<", "? Or "%", etc., the data processing apparatus 100 does not execute the operation command corresponding to the operation parameter.
Therefore, a user can directly use Chinese to establish a Chinese data table in the Hbase database, and the use experience of the user is improved.
It should be noted that, in the parameter verification method provided in the embodiment of the present application, the data processing apparatus 100 performs the method by modifying Hbase data after source code.
