Problems solved by technology

For example, when parsing the first picture, it is necessary to find the position of the header fields such as Content-Type, Content-Transfer-Encoding, and Content-ID in the data packet body in sequence, which means that the receiving end needs to traverse the data packet body multiple times. Only then can the image information be successfully parsed, thus increasing the parsing time

Embodiment Construction

[0044] In order to reduce parsing time complexity and time when parsing data content delivered by a server, embodiments of the present invention provide a data content parsing method and device.

[0045] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

[0046]Through the analysis of the parsing process of the data content in the prior art, it can be seen that the key elements of parsing the data content are when accurately locating the start position of the binary content and the length of the binary content. After careful analysis of the MIME protocol, it can be found that the data co...

Abstract

The invention discloses a data content analytic method and a data content analytic device, and the method and the device are used for lowering analytic time complexity and reducing analysis time when data content issued from a server is analyzed. The data content analytic method comprises that when data content in a data packet body is analyzed, characters contained in the data content are traversed in sequence, and American standard code for information interchange (ASCII) value and an ASCII character corresponding to each character are confirmed; according to the confirmed ASCII value, the ASCII character and a preset matching array, matching value corresponding to each character is confirmed; according to the matching value corresponding to each character and the ASCII character, the initial position of a head field is confirmed, and the head field is analyzed; and according to the analyzed head field, the initial position of binary system content and the size of the binary system content are confirmed, and the binary system content is analyzed.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal data analysis, in particular to a data content analysis method and device. Background technique [0002] Multipurpose Internet Mail Extensions (MIME, Multipurpose Internet Mail Extensions) is an Internet standard that extends the e-mail standard so that it can support e-mail messages in multiple formats such as non-ASCII characters and binary format attachments. The MIME protocol is widely used in the mobile Internet, and many applications use this protocol to transmit static resources such as pictures, audio, and text files. The protocol information header includes fields such as content type (Content-Type), content transfer encoding (Content-Transfer-Encoding) and content identifier (Content-ID). When transmitting multiple data contents, the Content-Type can generally be defined as Content-Type: multipart / mixed; boundary=End (End is a character string customized by the server as...
