For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1, a connection relationship between a browser driver application, a hardware device, and a browser in a browser driver-based online education system is provided, in which the browser driver mainly implements two functions: the method comprises the following steps of communication with hardware equipment and interaction with a browser.
In an embodiment of the application, the browser driver application may listen for operation requests on the browser based on the communication protocol. Preferably, the browser driver application may bind with the browser based on a communication protocol upon detecting the browser launch. Interaction with the browser is then effected based on the protocol.
In a preferred implementation, a Selenium2.0, also known as Selenium WebDriver, may be used to launch the browser (the working process of Selenium2.0 is shown in fig. 2).
The method mainly comprises the following steps of binding: namely, the background can simultaneously start the WebService based on the WebDriver Wire protocol as the Remote Server of the Selenium and bind with the Browser Web Browser, and then the Remote Server starts to monitor the operation request on the Browser in the Client terminal.
Step two, sending an Http Request based on a WebDriver Wire protocol: when the browser driver application code is executed, the browser driver application code serves as a Client terminal, and a page operation Request needing to be executed is sent to a RemoteServer in an Http Request mode. The body of the Http Request describes specific operations to be executed by the browser in a JSON format specified by a WebDriver Wire protocol.
Step three, requesting the Webdriver to operate the browser: after receiving the request, the Remote Server can analyze the request and send an analysis result to the WebDriver.
Step four, operating the browser by the Webdriver: the operation of the browser is actually performed by WebDriver. The WebDriver can be regarded as a Native Component (Native Component) for directly operating the browser, and generally, when a test environment is built, the WebDriver corresponding to the browser needs to be downloaded first.
It should be noted that after selenium2.x has proposed the concept of WebDriver, it provides an entirely alternative way to interact with the browser, i.e. using the native API of the browser, packing into a set of more object-oriented selenium WebDriver APIs, and operating directly the elements in the browser page, even operating the browser itself (screen capture, window size, start, close, install plug-ins, configure certificates, etc.). Because the native API of the browser is used, the speed is greatly improved, and the calling stability is handed to the browser manufacturer, which is obviously more scientific. However, the side effect is that different browser vendors have some differences in the operation and presentation of Web elements, which directly results in that the SeleniumWebDriver needs to be different from browser vendor to provide different implementations. For example, Firefox has a special FirefoxDrver, Chrome has a special Chrome driver, and so on. (even including android driver and iOSWebdriver)
The WebDriver Wire protocol is universal, that is to say, whether FirefoxDriver or ChromeDriver, after starting, Web Service based on the set of protocol is started at a certain port. For example, FirefoxDrver initialization succeeds by default, starting with http:// localhost:7055, while ChromeDriver is roughly like http:// localhost: 46350. Based on the above, it can be known that any API calling WebDriver needs to send a command, actually an HTTP request, to a Web Service on the listening port by means of a commandexecutor. In the body of the HTTP request of the present application, a JSON-formatted character string specified by the WebDriver Wire protocol tells the Selenium user what the browser wants to do next.
In creating a WebDriver, the Selenium first confirms whether the native component of the browser is available and the version matches. Then, a whole set of Web Service is started in The target browser, and The Web Service uses The protocol defined by The self design of The Selenium and is named as The Webdriver WireProtocol. The set of protocols is very powerful and can operate a browser to do almost anything, including open, close, maximize, minimize, element locate, element click, upload file, etc.
In a preferred implementation manner, the hardware interface between the hardware device and the browser is any one of bluetooth, a serial port, and a USB. And the browser driver application carries out hardware communication through the hardware equipment through a hardware interface and transmits the monitored operation instruction corresponding to the operation request to the hardware equipment. For example: the Google Chrome browser adds WebUSB and WebBluetooth APIs, allows a website to interact with equipment connected to the running browser, and controls a serial port by using an ActiveX control and JS call a serial port control of MSCOMM32. dll. For another example, the JavaScript language is generally a web page programming language, and is more suitable for some application designs of the foreground, or controls of the C # language are used to control the serial port, and then JS + AJAX is used to interact with the C # language to obtain the serial port data.
In the following, a specific example of online education will be described, such as the interface of the computer-operated robot experiment shown in fig. 3, the whole screen is a browser interface. The upper right part is an experimental guide providing prompts for the operation of the robot, the contents of which can be dynamically updated according to the state of the robot or manually reviewed. The lower right part is an experimental record, and data in the experiment can be input in the area. The browser driver application starts the browser and at the same time starts a service that listens to the browser's operations. When the student presses the button of the operation (representing front, back, left and right respectively), the service monitors the operation and transmits the operation to the browser driver application, the browser driver application transmits the instruction to the robot through a communication protocol with the robot, and then the robot moves according to the instruction. The position or number of steps of the robot's motion as response information may be passed from the robot to a browser driver application which passes the response information to a browser for display on an interface, or the next output position may be calculated from the current position.
In the embodiment of the invention, two basic functions are simultaneously realized by setting a browser driver application, namely, the browser is communicated with hardware, and the browser is bound with a communication protocol while the browser is started, wherein the content of the communication protocol is that the browser is monitored, so that an application program can monitor an operation request on a browser page. The control and communication of the browser to the hardware equipment are realized, so that the teaching platform can simultaneously control the hardware and access teaching resources and carry out interaction; the method comprises the steps that a Web Service bound with a browser is started to serve as a Remote Server, and an operation request of a Client terminal is monitored, so that interaction with the browser is realized; by adopting the communication between the browser and the hardware, the access to the hardware based on the B/S architecture is realized.
It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a Read-only memory (ROM), a Random Access Memory (RAM), or the like.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
