Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples. Referring to fig. 1, fig. 1 shows a flow of implementing a method for detecting internet access according to an embodiment of the present invention, which is detailed as follows:
in step S101, when an internet access detection request input by a user is received, an operation condition of a physical networking device of a current terminal device is detected.
In the embodiment of the invention, in the process of software development or design, a user often needs to determine whether the terminal device currently used by the user successfully accesses the internet or not, so that the designed or developed software can normally or quickly access the internet in subsequent use. Therefore, when an internet access detection request input by a user is received, the operation condition of the physical networking equipment of the current terminal equipment is detected, so that the condition that the internet cannot be normally accessed due to the failure of the physical networking equipment is rapidly checked.
Here, the API function internet getconnectiedstate provided by the Windows system is used to detect the operation of the physical networking device of the current terminal device. If the physical networking equipment can normally operate, the function returns a TRUE value to indicate that the networking equipment of the current terminal equipment normally operates, such as a network cable is connected and a network card normally operates. If the physical networking equipment cannot normally operate, the function returns a FLASE value to indicate that the networking equipment of the current terminal equipment has abnormity, such as no network cable is connected or the network card cannot normally operate.
In step S102, it is determined whether to continue the internet access detection according to the detection result of the operation condition of the physical networking device of the current terminal device.
In the embodiment of the invention, when the physical networking equipment of the current terminal equipment has faults, such as no network cable is connected, the network card can not work normally and the like, the current terminal equipment can be quickly judged not to access the Internet, and a data packet or a character does not need to be sent again to determine that the current terminal equipment does not access the Internet according to the returned delay information, so that the time is greatly saved, and the working efficiency of Internet access detection is improved.
Preferably, the embodiment of the present invention provides specific implementation steps of the method for determining whether to proceed with internet access detection, as shown in fig. 2, which are detailed as follows:
in step S201, it is determined whether to continue the internet access detection according to the detection result of the operation condition of the physical networking device of the current terminal device.
In the embodiment of the present invention, the detection result of the operation condition of the physical networking device of the current terminal device includes that the physical networking device of the current terminal device operates normally and the physical networking device of the current terminal device operates abnormally.
In step S202, if the physical networking device of the current terminal device operates normally, internet access detection is continued.
In the embodiment of the present invention, it can only be determined whether the physical networking device of the current terminal device normally operates through the API function Internet getconnectincestate, and it cannot be determined whether an Internet service is obtained, that is, it cannot be determined that the Internet is accessed, for example, the current terminal device only accesses the local area network, and when the local area network is not accessed to the Internet, the API function also returns a TRUE value, so that it is necessary to continue the access detection of the Internet to further determine whether the current terminal device successfully accesses the Internet according to the detection result.
In step S203, if the physical networking device of the current terminal device is abnormally operated, a first prompt message indicating that the current terminal device does not access the internet is output.
In the embodiment of the present invention, the first one of the first prompting messages is only used for distinguishing the prompting messages obtained under different conditions, and has no other special meaning. It is to be understood that the same applies to the second, third, fourth, etc., which will appear hereinafter to distinguish between the prompt messages acquired in different instances.
Here, the abnormal operation of the physical networking device indicates that the physical networking device cannot normally operate due to the fact that the physical networking device is not connected with a network cable, the network card is not installed, the network card is not driven, or the network card fails, so that the abnormal operation is caused. Obviously, when the physical networking device operates abnormally, the internet cannot be accessed, and therefore, the situation of internet access does not need to be detected any more. When detecting that the physical networking equipment of the current terminal equipment operates abnormally, directly outputting prompt information that the current terminal equipment does not access the Internet. For example, prompt information that the physical networking device of the current terminal device has a fault, the network cable of the current terminal device is not connected, and the like is output.
In step S103, if it is determined that the internet access detection is continued, specific information is acquired to continue the internet access detection.
In the embodiment of the present invention, the specific information includes domain name information or Uniform Resource Locator (URL) information. The specific information may be a commonly used website input by the user, or a pre-set website pre-stored for testing whether the internet is successfully accessed, so as to perform a connection test according to domain name information or URL information included in the website, and determine whether the current terminal device is successfully accessed to the internet by sending and receiving a result of the data, which is not specifically limited herein.
Preferably, the embodiment of the present invention provides specific implementation steps of a method for detecting internet access as shown in fig. 3, which are detailed as follows:
in step S301, domain name information or URL information is acquired; the domain name information comprises a domain name address, and the URL information comprises a URL address.
In the embodiment of the invention, the internet access detection is carried out by acquiring the domain name information or the URL information, and whether the current terminal equipment successfully accesses the internet is determined by sending and receiving the data result to the domain name address contained in the domain name information or the URL address contained in the URL information.
In step S302, the domain name address or the URL address is resolved, and it is determined whether to return the corresponding IP address within a first preset time.
In the embodiment of the present invention, the first and second preset times in the first preset time and the second preset time hereinafter do not have other special meanings, and are used to distinguish different preset times, where the preset time is a time length set to determine whether a step is overtime, and the unit is generally millisecond.
In the process of performing a connection test according to domain name information or URL information contained in the website and determining whether the current terminal device successfully accesses the internet by sending and receiving data results, a domain name address or a URL address is resolved by acquiring corresponding domain name information or URL information from a commonly used website input by a user or a pre-stored preset website to determine whether the domain name address or an IP address corresponding to the URL address can be returned within a first preset time to further determine whether the current terminal device successfully accesses the internet.
Here, domain name resolution is performed through a network function gethostbyname provided by the WinSock API library to obtain a corresponding IP address. If the corresponding IP address can be returned within the first preset time, connection is established with the IP address to transmit and receive data, and whether the current terminal equipment is successfully accessed to the Internet is determined according to the result of transmitting and receiving the data.
In step S303, if the corresponding IP address is not returned within the first preset time, second prompt information indicating that the current terminal device does not access the internet is output.
In the embodiment of the invention, if the corresponding IP address is not returned within the first preset time, namely the time required for acquiring the IP address exceeds the first preset time, the current terminal equipment is not accessed to the Internet and cannot acquire the corresponding IP address, and then corresponding prompt information is output to prompt the current terminal equipment not to be accessed to the Internet without entering the step of sending and receiving data, so that the time required for detection is reduced, and the working efficiency of Internet access detection is improved.
Preferably, the embodiment of the present invention provides specific implementation steps of another method for detecting internet access as shown in fig. 4, which are detailed as follows:
in step S401, if the corresponding IP address is returned within the first preset time, a connection request is sent to the IP address and it is determined whether the connection is successfully established within the second preset time.
In the embodiment of the invention, after the domain name address is analyzed through the network function gethostbyname provided by the WinSock API library, if the analysis is not overtime, an IP address return value is obtained, namely the corresponding IP address is returned within the first preset time, and at the moment, a connection request is sent to the IP address to connect the IP address. And in the process of connecting the IP address, further judging whether the current terminal equipment is successfully accessed to the Internet according to whether the connection is successfully established with the IP address.
Here, if the domain name address or the IP address corresponding to the URL address is returned within a first preset time, a socket is established, and the returned IP address is copied into an address structure, so as to implement connection to the IP address through a network function connect provided by the WinSock API library.
In step S402, if the connection is not successfully established, third prompt information indicating that the current terminal device does not access the internet is output.
In the embodiment of the invention, after the domain name address is analyzed through the network function gethostbyname provided by the WinSock API library, if the return value is SOCKET _ ERROR, the connection IP address is overtime, and the connection cannot be successfully established, namely the current terminal equipment does not access the Internet, at the moment, the prompt message that the current terminal equipment does not access the Internet is output, and the step of sending and receiving data is not needed, so that the time required by detection is reduced, and the work efficiency of Internet access detection is improved.
Preferably, the embodiment of the present invention provides specific implementation steps of another method for detecting internet access as shown in fig. 5, which are detailed as follows:
in step S501, if the connection is successfully established, a HyperText Transfer Protocol (http) request packet is sent to the IP address, and it is determined whether the http request packet is successfully sent.
In the embodiment of the invention, after the connection is successfully established with the IP address corresponding to the domain name address or the URL address, the http request data packet is sent to the IP address so as to judge whether the current terminal equipment is successfully accessed to the Internet according to whether the http request data packet is successfully sent.
In step S502, if the http request packet is not successfully sent, fourth prompt information that the current terminal device does not access the internet is output.
In the embodiment of the invention, if the http request data packet is not successfully sent within the preset time, the current terminal equipment is not successfully accessed to the internet.
Here, the http request packet is data constructed in a form of a character string and stored to the variable buf. In the embodiment of the invention, the constructed http request data packet is sent by calling the network function send provided by the Winsock API library, and whether the http request data packet is successfully sent is determined according to the return value of the network function send. For example, when the return value of the network function send is SOCKET _ ERROR, it indicates that the http request packet transmission fails, that is, the current terminal device does not access the internet, and at this time, a prompt message that the current terminal device does not access the internet is output, and the step of transmitting data and receiving data is not required, so that the time required for detection is reduced, and the work efficiency of internet access detection is improved.
Preferably, after step S501, the following steps are further included:
and if the http request data packet is successfully sent, receiving data corresponding to the http request data packet returned by the IP address, and outputting fifth prompt information that the current terminal equipment has accessed the Internet.
In the embodiment of the invention, when the http request data packet can be successfully sent, the data corresponding to the http request data packet returned by the connected IP address can be received, which indicates that the current terminal equipment can successfully access the Internet, and at this time, the prompt information that the current terminal equipment has accessed the Internet is output, so that the user can conveniently perform the next test on the software designed or developed by the user.
The detection result that the current terminal equipment is not successfully accessed to the Internet is quickly checked through response results after each step in the process of establishing connection with the IP address corresponding to the domain name address or the URL address and sending and receiving data to the IP address, and related prompt messages are output, so that the detection result that the current terminal equipment is accessed to the Internet is quickly determined, the problems that a PING command process needs to be established, the I/O operation of a program is increased, the application and release processes of resources are avoided, the Internet access detection efficiency is improved, uncertain keywords do not need to be analyzed, and the error rate caused by the fact that the PING mode needs to analyze returned data is avoided.
In the embodiment of the invention, when an Internet access detection request input by a user is received, the operation condition of the physical networking equipment of the current terminal equipment is detected; so as to determine whether to continue the internet access detection according to the detection result of the operation condition of the physical networking equipment of the current terminal equipment; and after determining to continue the Internet access detection, acquiring specific information to continue the Internet access detection, quickly checking that the Internet cannot be accessed due to abnormal operation of the physical networking equipment, so that the waiting time is shortened, the working efficiency of Internet access detection is improved, and when the physical networking equipment operates normally, whether the current terminal equipment is accessed to the Internet or not is further detected through the specific information, so that the Internet detection accuracy is improved, and the error rate is avoided.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
