Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
Fig. 1 shows a flowchart of an embodiment of the method for quickly generating a poster according to the present invention, which is executed by a computer device and applied to a screenshot application of the computer device. The computer device may be an access device. The access equipment comprises a load server and a plurality of node servers, wherein the load server is in communication connection with each node server, and each node server is arranged on a host and is in communication connection with a Google headless browser on the host. The information interaction between the client poster making and the Google headless browser is established through the access equipment. The method for quickly generating the poster is realized according to the Google headless browser. As shown in fig. 1, the method comprises the steps of:
step 110: and obtaining a poster sharing request, wherein the poster sharing request carries the floor information and the broker information.
Before obtaining the poster sharing request, responding to a trigger operation that a broker clicks a sharing button through a client page, and generating the poster sharing request. The client page may be an applet page, an application page, and a web page. The page may be a building details page or a house display list. Illustratively, there may be a share button in the building details page or house display list.
In the embodiment of the invention, after a user clicks a sharing button, a poster sharing request is generated, and the poster sharing request comprises the floor information corresponding to the page and the corresponding broker information. The broker information includes information such as broker ID, broker avatar, broker two-dimensional code information, and broker contact information. The information such as the broker ID, the broker avatar, the broker two-dimensional code information, and the broker contact information may be obtained from a broker account pre-stored in the client.
Step 120: determining a target poster template according to the floor information, and generating a target html poster page according to the target poster template and the broker information; the target poster template is an html poster template.
In the embodiment of the invention, the target poster template is an html poster template, and each html poster template corresponds to a target template network address. Wherein the target poster template is stored in association with the floor information. Step 120 further comprises:
acquiring a target template network address corresponding to the target poster template;
opening the target poster template according to the target template network address;
generating a target network address of the target html poster page according to the target template network address; storing the target network address in association with the broker ID;
and generating a target html poster page in the target network address according to the target poster template and the broker information.
Step 130: generating a screenshot request for the target html poster page; and the screenshot request comprises a target network address of the target html poster page and screenshot quality requirement information.
And when the target html poster page is determined to be generated, generating a screenshot request for the target html poster page.
In the embodiment of the invention, corresponding screenshot quality requirement information can be configured for each poster template in advance. The screenshot quality requirement information includes size information, pixel information, and the like.
Step 140: sending the screenshot request to a target node server through a load server; the target node server is any idle node server determined from the plurality of node servers through the load server.
The method for quickly generating the poster is realized according to the Google headless browser. Because the poster is drawn by the html, the corresponding network address (namely the page url) and the screenshot quality requirement information are sent to the screenshot service in the Google headless browser for screenshot. Specifically, the screenshot can be realized through Puppeneer screenshot service of a Google headless browser. However, considering that different kinds of application layers need to be installed and compiled together with the google headless browser, respectively, so that the service that the google headless browser can be called on the specific type of application layer is realized. Therefore, when a new function needs to be realized, a google headless browser needs to be installed on the application layer with the corresponding function, but because the volume of the data packet of the application layer is large, the time cost and the computing resource cost for recompiling the application layer after installing the google headless browser each time are large. This results in inefficient access by the application layer to google headless browsers in the prior art. Therefore, in the method for quickly generating the poster, the Google headless browser is arranged on the plurality of hosts, each host corresponds to one Google headless browser and one node server, and the load server is arranged to access each node server, so that communication with the headless browser is realized. By the mode, during development, a Google headless browser is not required to be installed on each host, and therefore working efficiency is improved.
Before forwarding the screenshot request to the corresponding target node server through the load server, the load server needs to be configured first, so that the load server establishes communication with the plurality of node servers.
Step 1401: and respectively acquiring the service port information of each node server.
The service port information is a monitoring port exposed by each node server, the service port information of different node servers is different, and each node server monitors the message from the service port, so that the message sent to the service port from the outside is processed. In one embodiment of the present invention, the service port information of one node server may be the port number 9222.
Step 1402: and configuring the load server according to the service port information so as to enable the load server to establish communication connection with each node server respectively.
The process of configuring the load server is as follows: and writing the service port information monitored outwards by each node server into a configuration file of a forwarding module of the load server. In one embodiment of the present invention, the load server may be a proxy server with load function, such as Nginx, docker, or the like. When the type of the load server is Nginx, the specific forwarding module may be an upstream module.
Considering that there may be a plurality of screenshot requests sent by the target application layer within a period of time, in order to process each screenshot request in time and avoid that the screenshot request response time is too long or the node server crashes due to the proxy load being greater than the processing capacity, in an embodiment of the present invention, a policy setting of load balancing may be further performed on the load server to balance and schedule the screenshot requests forwarded to each node server.
In an embodiment of the present invention, the process of determining one node server from a plurality of node servers that have established a connection with a load server as a target node server may be that the target node server is determined by the load server according to a preset load balancing policy.
The specific load balancing policy may include the following: first, a polling method: and forwarding the screenshot request to each node server in turn according to the received time sequence. Secondly, a weighted polling method: and determining the weight value corresponding to each node server according to the current load condition and the system configuration condition of each node server. And when the weighted polling is carried out, the screenshot requests are distributed to the node servers in sequence according to the time sequence of receiving the screenshot requests by the load servers and the descending order of the weight values of the node servers. Third, minimum connection number method: and dynamically selecting one node server with the least current waiting connection number as a target node server to process the current screenshot request according to the current connection condition of each node server. And writing the load strategy into a configuration file of a forwarding module of the load server.
Step 150: and acquiring a local IP address and local port information of a host corresponding to the target node server, and generating a screenshot service request according to the local IP address, the local port information and the screenshot request.
In the embodiment of the invention, as the operation communication protocol of the Google headless browser is a DevTools protocol which is a debugging protocol, the operation of the Google headless browser is only allowed by the request of the local IP address and the local port, and a host corresponding to one Google headless browser corresponds to one local port and one or more IP addresses. In order to enable each node server to send a screenshot service request from a load server to a host corresponding to a browser corresponding to the node server, each node server needs to be installed on a host corresponding to a google headless browser respectively, and each node server needs to be set, so that communication connection is established between the node server and the host corresponding to the google headless browser corresponding to the node server.
Therefore, before the screenshot service request is sent to the google headless browser through the target node server, the target node server is required to be sent, and steps 1501 to 1502 are included.
Step 1501: and installing one node server on the host corresponding to each Google headless browser.
The node server and the google headless browser are installed on the same host, so that in one embodiment of the present invention, the node server may be a proxy server with reverse proxy function, such as Nginx, quid, and Varnish.
Step 1502: and respectively configuring each node server so that each node server respectively establishes communication connection with the Google headless browser on the corresponding host.
The process of configuring the node server includes first setting the IP address and port of the local server,
and in the configuration file of the server module of the node server, an address transferred by the proxy is set as a local IP address and a local port of a host corresponding to the local Google headless browser by using a proxy address setting command (such as a proxy _ pass command).
After the configuration of the node servers is completed, the service of the node servers is started, and thus communication connection is established between each node server and the Google headless browser on the host machine where the node servers are arranged.
Therefore, the technical scheme is different from the technical scheme that the resource of the Google headless browser is directly accessed without proxy, so that binding installation and compiling with the Google headless browser are required to be carried out again when the application layer is changed and modified every time. Meanwhile, the remote access efficiency of the Google headless browser is improved based on the load balancing function of the load server and the plurality of node servers.
In the embodiment of the invention, the screenshot request also comprises communication protocol information, the screenshot service request comprises Host request header information, and the Host request header information comprises request server port information and a request server IP address;
the acquiring a local IP address and local port information of a host corresponding to the target node server, and generating a screenshot service request according to the local IP address, the local port information and the screenshot request further comprises the following steps:
step 1510: setting the request server port information as the local port information and the request server IP address as the local IP address by the target node server; in an embodiment of the present invention, a setting statement of a Host request header is first defined in a server configuration file of a target node server, where the setting statement of the Host request header is as follows:
proxy_set_header Host $server_addr$port。
where the $ server _ addr variable represents the local server IP address and the $ port variable represents the local server port information.
The method comprises the steps of firstly obtaining a local IP address and local port information, then writing the setting statement into a configuration file of a server module of a target node server, setting a request server port for sending a service request in a Host request header as the local port information of a Host corresponding to a chromosome browser, and setting the request server IP address for sending the service request as the local IP address of the Host corresponding to the chromosome browser.
In one embodiment of the invention, configuring the target node server may include the following: the method comprises the steps of firstly setting a monitoring port of a target node server, then setting a local port of a Host corresponding to the target node server, setting an http communication protocol version in the proxy process, setting Host request header information and setting a target address of the proxy.
Specifically, the step of setting the Host request header may be to write a proxy _ set _ header Host $ server _ addr $ port statement in the configuration file of the target node server, and set the Host request header as a combination of the local port information of the Host corresponding to the target browser and the local IP address of the Host, that is, to make the address of the client request identified by the target browser be the local port information plus the local IP address.
The target address to which the proxy is set may be a proxy _ passttp:// 127.0.0.1:9221 statement written in the configuration file of the target server, so that the requesting proxy is forwarded to http://127.0.0.1:9221 (i.e. the local IP address of the host corresponding to the chrome browser where the target node server is located plus the local port address) for processing.
Step 1511: and generating the screenshot service request by the target node server according to the communication protocol information and the Host request header information.
Step 160: sending the screenshot service request to a target browser through the target node server so that the target browser can verify the screenshot service request; the target browser is a Google headless browser corresponding to the target node server.
And the target browser verifies the screenshot service request according to the communication protocol information in the screenshot service request and the Host request header information.
Step 170: and when the verification is passed, acquiring screenshot service information corresponding to the screenshot service request returned by the target browser.
In an embodiment of the present invention, the screenshot service information includes a target access link, where the target access link is used to provide a target access interface, the target access interface may be an interface of a Puppeteer screenshot service, and the obtained target service information may include the following aspects: the Browser information is 'Browser', which is a HeadlessChrome, Google headless Browser, as 'HeadlessChrome/85.0.4183.121'. Communication Protocol Version information such as "Protocol-Version": 1.3 "and target service links such as:
"webSocketDebuggerUrl": "ws://192.168.1.45:9221/DevTools/browser/edeb113e-70e3-45a6-bad7-a50d66cceef9"。
based on a service mechanism of a Google headless browser, the communication protocol type of the target service link is a Websocket type, in the Websocket communication protocol, a browser server and a client can directly establish connection and perform bidirectional data transmission only by completing one-time handshake. The target access link corresponds to a target access interface, and the target application layer can access the resource provided by the host corresponding to the chromosome browser on the target access interface based on a debugging protocol approved by the chromosome browser, such as the DevTools protocol, wherein the target access interface can be a client based on the DevTool protocol, which is configured in advance.
Step 180: and accessing the target browser according to the screenshot service information so that the target browser performs screenshot operation on the target html poster page according to the screenshot request.
And when the Google headless browser opens a target html poster page according to the target network address, indicating Puppeneer screenshot service of the Google headless browser to perform screenshot operation.
Step 190: and obtaining a poster picture according to the screenshot operation.
And after the target browser conducts screenshot operation on the target html poster page according to the screenshot request, the obtained base64 information of the poster picture is obtained. And analyzing the poster picture according to the base64 information.
