In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic implementation flow diagram of a method for testing a network state according to an embodiment of the present invention, and as shown in the drawing, the method may include the following steps:
step S101, receiving a first request sent by a client, and generating response information of the first request.
Step S102, feeding back response information of the first request to the client, and pushing first preset information to the client.
In practical application, after receiving a request sent by a client, a server returns response information corresponding to the request to the client, which can be regarded as a relationship between a request and a response. Illustratively, the server returns the page information to the client after receiving a request of the client to browse the page.
In the embodiment of the invention, the server sends the first preset information to the client while returning the response information corresponding to the request to the client. For example, the first preset information may be a JavaScript script. The client actively sends feedback information to the server after executing the JavaScript script, and specifically what feedback information is sent is preset in the JavaScript script. It should be noted that the "first" in the first request and the first preset information is only used to distinguish different requests and different preset information, and is not used for counting.
Step S103, receiving first feedback information and second feedback information which are sent by the client according to the sequence after the client executes the first preset information, and judging the network state by using the first feedback information and the second feedback information.
In practical application, the first preset information may be manually preset, and after the client executes the first preset information, two pieces of feedback information are generated and sent to the server according to the sequence. Specifically, the first feedback information is sent to the server first, and then the second feedback information is sent to the server according to the sequence. In practical applications, the interval between the sending of the first feedback information and the sending of the second feedback information is negligible.
Optionally, the determining a network status by using the first feedback information and the second feedback information includes:
if the first feedback information and the second feedback information are received according to a sending sequence within a first preset time, judging that the state of the forward network is normal, wherein the forward network is a network from the client to the server;
if the first feedback information is not received within a first preset time, judging that the first feedback information is lost;
and if the first feedback information is received within a first preset time and the second feedback information is not received, judging that the second feedback information is lost.
Optionally, the determining a network state by using the first feedback information and the second feedback information further includes:
and if the second feedback information and the first feedback information are received according to a first preset sequence within a first preset time, determining that the forward network is out of order.
In practical applications, the first preset time may be preset manually, and the set rule is that the first preset time is long enough to ensure that the server can completely receive the first feedback information and the second feedback information under the condition that the network is normal. Specifically, the receiving according to the sending sequence includes receiving the first feedback information first and then receiving the second feedback information. Specifically, the second feedback information is received first, and then the first feedback information is received according to the first preset sequence.
In this embodiment, the state of the forward network is tested, and the forward network is a network from the client to the server. In the forward network, the client is the sender and the server is the receiver.
For example, assuming that the time for the server to receive all the first feedback information and the second feedback information is 10s under the condition that the forward network is normal, the first preset time may be set to be 15s (with a certain grace time). If the first feedback information and the second feedback information are received within 15s, the forward network state is normal. If the first feedback information is received within 15s, but the second feedback information is not received, it indicates that the second feedback information is lost, i.e. it indicates that packet loss occurs to the network. If the first feedback information is not received within 15s, and the second feedback information is not received, it indicates that the first feedback information is lost, that is, it indicates that packet loss occurs to the network (because the first feedback information is received according to the transmission sequence, if the first feedback information is lost, the second feedback information will wait for the client to retransmit the first feedback information and then reach the server, and in this case, the second feedback information may also be lost). If the second feedback information is received first and then the first feedback information is received within 15s, the forward network disorder is indicated.
The embodiment of the invention receives a first request sent by a client and generates response information of the first request; feeding back response information of the first request to the client, and pushing first preset information to the client; receiving first feedback information and second feedback information which are sent by a client after the client executes the first preset information, and judging the network state by using the first feedback information and the second feedback information; the forward network state can be rapidly and accurately known.
Fig. 2 is a testing method of network status according to another embodiment of the present invention, and as shown in the figure, the method may include the following steps:
step S201, receiving a first request sent by a client, and generating response information of the first request.
Step S202, feeding back response information of the first request to the client, and pushing first preset information to the client.
Steps S201 and S202 are the same as steps S101 and S102, and specific contents can be found in steps S101 and S102.
Step S203, receiving a second request sent by the client, and generating response information of the second request.
Step S204, splitting the response information of the second request into first response information and second response information, and respectively constructing first trigger information and second trigger information for the first response information and the second response information; the first trigger information is used for indicating the client to send the first trigger information to the server after receiving the first response information, and the second trigger information is used for indicating the client to send the second trigger information to the server after receiving the second response information.
In practical applications, the first trigger information may be an RST _ STREAM frame (the role of this frame is termination), based on the characteristics of the HTTP/2 protocol; in this embodiment, the first response message may be made dependent on itself by using a PRIORITY frame, which may cause the client to send an RST _ STREAM frame to the server, and the second trigger message may be a SETTINGS frame (which may be used to cause the client to return an acknowledgment flag message to the server after receiving the frame). Step S205, after the first response information and the first preset trigger information are packaged, and the second response information and the second preset trigger information are packaged, they are respectively fed back to the client according to the sequence.
Optionally, after the first response information and the first preset trigger information are packaged, and the second response information and the second preset trigger information are packaged, and then are respectively fed back to the client according to the sequence, the method further includes:
if the first trigger information and the second trigger information fed back by the client are received according to the feedback sequence within a second preset time, the backward network state is normal, and the backward network is a network from the server to the client;
if the first trigger information fed back by the client is not received within a second preset time, determining that the first response information is lost;
and if the first trigger information fed back by the client and the second trigger information fed back by the client are not received within a second preset time, judging that the second response information is lost.
Optionally, after the first response information and the first preset trigger information are packaged, and the second response information and the second preset trigger information are packaged, and then are respectively fed back to the client according to the sequence, the method further includes:
and if second confirmation information, the first trigger information and the second trigger information corresponding to the second response information sent by the TCP layer are received within second preset time according to a second preset sequence, judging that the backward network is out of order.
In this embodiment, the backward network is a network from a server to a client, the server is a sender, and the client is a receiver.
The second preset sequence is specifically to receive first acknowledgement information corresponding to second response information sent by a Transmission Control Protocol (TCP) layer, and then receive the first trigger information and the second trigger information at the same time. In practical application, due to the TCP mechanism, if the two response messages are not returned according to the feedback sequence, the second response message will be buffered in the TCP layer, and the client will receive an acknowledgement message sent by the TCP layer to indicate that the TCP layer has received the second response message, until the client retransmits the first response message, the TCP layer will not submit the retransmitted first response message and the buffered second response message to the client together.
Illustratively, whether the first preset trigger information is triggered within the time A is confirmed; if the first preset trigger information is triggered in the time A, whether the second preset trigger information is triggered in the time B is confirmed; if the second preset trigger information is triggered within the time B, judging that the backward network state is normal; if the second preset trigger information is not triggered within the time B, judging that the second response information is lost; if the first preset trigger information is not triggered in the time A, whether confirmation information which is sent by a TCP layer and corresponds to the second response information is received in the time C is confirmed; if the confirmation information is received within the time C, the network is judged to be out of order; and if the confirmation information is not received within the time C, judging that the first response information is lost. It should be noted that A, B, C is only for distinguishing time, time a may be a time when the first preset trigger message is triggered in a normal network state, time B may be a time when the second preset trigger message is triggered after the first preset trigger message is triggered in a normal network state, and time C may be a time when the TCP layer receives the second preset trigger message after the first preset trigger message is triggered in a normal network state, where the specific time is not particularly limited.
Referring to fig. 6, fig. 6 is a schematic diagram of a backward network state exception provided in this embodiment. Fig. 6(a) shows a case where the first response information is lost, fig. 6(b) shows a case where the second response information is lost, and fig. 6(c) shows a case where the backward network is out of order. In the figure, client represents a client, server represents a server, Req _2 represents a second request, Resp _2_1 represents first response information, Resp _2_2 represents second response information, RST _ STREAM represents first preset trigger information, and SETTINGS ACK represents confirmation information of the second preset trigger information.
The embodiment of the invention receives a first request sent by a client and generates response information of the first request; feeding back response information of the first request to the client, and pushing first preset information to the client; receiving a second request sent by a client, and generating response information of the second request; splitting response information of the second request into first response information and second response information, and respectively constructing first trigger information and second trigger information for the first response information and the second response information; packaging the first response information and the first preset trigger information, and packaging the second response information and the second preset trigger information, and then feeding back the installation sequence to the client respectively; the state of the backward network can be rapidly and accurately known.
Fig. 3 is a testing method of network status according to another embodiment of the present invention, as shown in the figure, the method may further include the following steps:
step S301, sending second preset information to the client, where the second preset information is used to control the client to send a data packet to a server.
Step S302, if a data packet sent by the client to the server is not received after sending the second preset information to the client, determining that the currently sent second preset information is lost.
The embodiment is used for detecting the packet loss states of a plurality of streams. Wherein, the second preset information may be WINDOW _ UPDATE frame, and the role of this frame is: indicating the size of the data window to be increased. The client may send a response size packet back to the server only if the client receives the WINDOWs UPDATE frame sent by the server.
For example, assume that there are N streams, each with an ID of 2i-1, and i indicates the Nth stream. If the WINDOWs _ UPDATE frame sent by the server to the client, which is the ith to be used on the 2i-1 stream, is lost, the server can only receive packets on the 1 st to 2(i-1) -1 st streams. The client cannot send the data packets on the 2i-1 to 2N-1 streams to the server until the i-th retransmitted packet for the WINDOW _ UPDATE frame acting on the 2i-1 stream reaches the client. The server can determine which packet is lost by observing the stream ID of the collected data.
Referring to fig. 7, fig. 7 is a schematic diagram of a backward network state exception provided in this embodiment. In the figure, DATA represents a packet.
The embodiment of the invention sends second preset information to the client, wherein the second preset information is used for controlling the client to send a data packet to a server; if the data packet sent to the server by the client is not received after the second preset information is sent to the client, judging that the currently sent second preset information is lost; the lost packet can be quickly and accurately found out under the condition of transmitting a plurality of data packets.
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.
