Embodiment 1
[0034] This embodiment involves the following business scenarios: if a user executes a business query, the sensitive field in the returned query result is parent, the field parent value type is a common string type, and the field value content needs to be masked, when a segmented Json message is received , the string content before processing is:
[0035] "parent": "zhangfei","birthday":"1988-10-10","favaritecolor":"red and blue","contact":{"telephone":"1379797778","description":";{ zhangsan}","originalName":"Zhang Er","remark":"13535363688:\"\"end","note":{"source":"dalian","target":"shenyang"}},
[0036] Such as image 3 As shown, it is a field-level permission control method based on streaming JSON parsing involved in this embodiment, and the specific steps include:
[0037] Step 1: The first character of the read string is a double quote, and there are no other characters before it, which is considered to be the beginning of the key.
[0038] Step 2: Start from the secon...
Embodiment 2
[0044] This embodiment involves the following business scenarios: a user executes a business query, and the sensitive field in the returned query result is contact, the field contact value type is an object type, the key value in the value content of contact remains visible, and the value value is replaced with *, so as to realize A mask for the value of this field.
[0045] When a segmented Json message is received, the content of the string before processing is:
[0046]"parent": "zhangfei","birthday":"1988-10-10","favaritecolor":"red and blue","contact":{"telephone":"1379797778","description":";{ zhangsan}","originalName":"Zhang Er","remark":"13535363688:\"\"end","note":{"source":"dalian","target":"shenyang"}},
[0047] Such as image 3 As shown, it is a field-level permission control method based on streaming JSON parsing involved in this embodiment, and the specific steps include:
[0048] Step 1: The first character of the read string is a double quote, and there are n...

Abstract
The invention relates to a field-level authority control method based on streaming JSON (JavaScript Object Notation) analysis, which comprises the following steps of: after reading and receiving a segment of segmented Json message every time, initializing and summarizing historical information, and splicing the last first token character object of the previous segment of Json message, the last second intact token character object of the previous segment of Json message and the current segment of Json message to form a new segment of Json segmented message; starting processing from the first character of the new Json segmented message, carrying out circulation, and reading the next character in sequence every time until the character string end mark of the segment of message is read; and judging the types of the characters obtained in the step 3 and performing corresponding processing. According to the method, the Json segmented messages are analyzed and processed one by one in a streaming processing mode, so that the circulation processing efficiency is remarkably improved.
Description
technical field [0001] The present invention relates to a technology in the field of information processing, in particular to a field-level authority control method based on streaming JSONparsing. Background technique [0002] Since different industries have relatively high sensitivity requirements for user data, when executing business data queries for different users, in the returned query results, it is hoped that certain sensitive field values in the returned results will be shielded according to different user permissions. exist figure 1 In the business scenario shown, a user needs to perform a business data query through the front-end client->message middleware->business service->database. Because the control at the database layer is more complicated, the control at the business service layer involves many business services Modification, so consider field-level permission control on the returned result data in the message middleware, and shield some sensitive...
