Description
Technical Field
The invention belongs to the technical field of Internet, and particularly relates to a method for realizing highlighting of HTTP request data in a webpage.
Background
In analyzing and debugging software for HTTP protocol network requests, it is often necessary to highlight captured network request data, so that an analyst using such software can obtain better user experience and improve analysis efficiency. From development cost and cross-platform compatibility considerations, there is currently an increasing choice of client software to develop using browser-based frameworks (e.g., electronics, nw. Js, CEF, etc.), with no exception to web request analysis and debugging software.
Under the development architecture, the interface of the software is usually implemented by using a webpage development technology, and the presentation of the network request data is usually also based on a webpage code editor. In a conventional code editor scenario, highlighting of codes usually only needs to consider a single data highlighting rule, and the code editor usually has built-in highlighting special effects for various languages; the highlighting of the network request data needs to consider the compound data highlighting rule, and the code editor generally does not reasonably highlight the request packet which does not belong to the development language, for example, in one request packet, the header of the request packet and the packet body of the request packet respectively belong to different types of data, and two different highlighting rules need to be adopted.
Thus, current web code editors have difficulty highlighting complex request data, nor do some regular expression-based highlighting rule schemes generally have versatility, giving false highlighting on specific data packets.
Disclosure of Invention
The invention aims to solve the problems, and provides a method for realizing the highlighting of HTTP protocol request data in a webpage, which realizes the highlighting of complex HTTP request data packets in the webpage through javascript language, is applicable to all scenes which are required to highlight the HTTP request data packets based on webpage development, supports the calling of the highlighting method through a web worker mode, and can improve the highlighting performance.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a method for implementing HTTP protocol request data highlighting within a web page, comprising the steps of:
s1, preprocessing incoming data, namely converting request data into a character string array;
s2, taking out one row of data from the character string array converted in the step S1, judging which state the current content is in by scanning each character in the current row of data, and recording the starting position and the state type of the content in the previous state if the previous state needs to be subjected to highlighting processing when the scanning process is switched from one state to the other state;
s3, executing the step S2 circularly until the processing is finished, obtaining all position and length information of the content needing to be highlighted, and representing the result by an integer array;
s4, after the step S3 is completed, returning an integer array, wherein each 5 numbers in the array are a group and represent a highlight content, and the 5 numbers respectively represent the relative line numbers of the highlight content in all the request data, the relative positions in the lines, the length of the highlight content, the highlight type and a reserved field;
s5, after the different editors acquire the array in the step S4, highlighting the content in the editors according to the position, the length and the type information of each highlighted content.
In the loop execution step S2, the processing of the request header and the processing of the request body are divided.
Further: in the analysis process of the request header, if the Content-Type header is encountered, recording the value corresponding to the Content-Type header, and extracting the Content-Type header provides a judging basis for selecting a process of FORM, MULTIPART, XML, JSON, HTML; if the Content-Type header contains the boundary=content, extracting the character string Content behind the boundary=as a composite Content boundary, wherein the boundary is used for providing basis for entering a highlighting analysis rule of the MULTIPART processing flow; if the request header is encountered to start with a blank or Tab, then the last request header state is considered not to end; other regular expression based methods have difficulty in handling this situation in order to properly parse the HTTP request header.
Further: in the process of executing step S2, if a blank line is encountered, including no content or only a custom "line feed," then the analysis flow is considered to enter into the process for the request body.
Further: in the processing of the request body, the selection of the corresponding value of the recorded header enters different processing states, so that different processing flows are entered, including FORM, MULTIPART, XML, JSON, HTML.
Further: when entering the FORM flow, defaulting to FORM state, encountering =, & gt, switching the data boundary symbols to FORM value, request parameter and data mark state respectively, and switching the rest to request parameter name state; the subsequent state switching is then performed according to step S2 and the highlight data is recorded.
Further: when entering the MULTIPART flow, defaulting to a composite content state, and enabling encountered-data boundary symbols to enter the composite content boundary state and the data marking state respectively; the subsequent state switching is then performed according to step S2 and the highlight data is recorded.
Further: when entering a JSON flow, defaulting to a JSON state, and entering a JSON array start state, a JSON object start state, a JSON character string start state and a data mark state respectively by [, {, ", and a data boundary symbol; the subsequent state switching is then performed according to step S2 and the highlight data is recorded.
Further: when entering XML and HTML flows, defaults are XML and HTML states respectively, and encountering < and data boundary symbols respectively enter an XML tag open state and a data mark state; the subsequent state switching is then performed according to step S2 and the highlight data is recorded.
