The following uses multiple figures to illustrate.

FIG. 1B is a block diagram of a browser application and a resource health management module according to an embodiment of the invention.

Please refer to FIG. 1B. In this embodiment, the browser application 20 includes a plurality of code modules, such as HyperText Markup Language (HyperText Markup Language, HTML) element module 210 (also known as HTML element module) ), resource timing (Performance Resource Timing) module 220 and resource timing application programming interface (Performance Resource Timing API) 230, browser database 250. In FIG. 1B, the browser application 20 has been loaded and the resource health management module 240 is running.

The HTML element module 210 is used to manage and execute the specifications and functions of various HTML elements (for example, picture element "<img />", paragraph element "<p> </p>", etc...). The specific details of the various HTML elements are not the technical solution focused in this embodiment, and will not be repeated here.

The resource timing module 220 is used to generate and record resource timing data (also known as resource timing objects) corresponding to the running HTML element program.

The Performance Resource Timing API 230 is a web application-oriented interface specified by the World Wide Web Consortium (W3C). It can be implemented in modern browser applications (such as Chrome, FireFox). , Edge, etc...). The resource timing data of the resources processed/loaded by the browser application can be queried through the resource timing application programming interface 230.

The browser database 250 is used to record management information of the browser application (for example, resource timing data or health status corresponding to the loaded target resource) or a log file (Log).

On the other hand, the resource health management module 240 includes an HTML picture element instance generation module 241, an onLoad event listening module 242, an onError event listening module 243, a resource health judgment module 244, a healthy resource management module 246, and an unhealthy resource Management module 247. The following will further use FIG. 2 and FIG. 3 to illustrate the interaction of the components of the resource health management module 240 and the resource health management module 240. It should be noted that the operation of the components of the resource health management module 240 can also be regarded as the overall operation of the resource health management module 240.

Fig. 2 is a flowchart of a resource health management method according to an embodiment of the present invention.

Referring to FIG. 2, in step S21, the HTML picture element instance generation module 241 generates a picture element instance corresponding to a target resource according to a target resource address, and loads the picture element instance through a network connection according to the picture element instance The target resource. The target resource address can be preset in the HTML image element instance generation module 241 or the browser database 250. The target resource address is, for example, the network address of the resource, and the browser application 20 can download the target resource according to the target resource address. The current domain of the network to which the electronic device 10 is connected may be different from the domain of the target resource; the communication protocol used by the browser application 20 may be different from the communication protocol of the target resource address. Here, the communication protocol includes Hypertext Transfer Protocol Secure (HTTPS) and HyperText Transfer Protocol (HTTP).

More specifically, the HTML picture element instance generation module 241 can use the HTML picture element (ie, "<img />") to package the target resource address through the HTML element module after identifying the target resource address , To become an HTML image element instance (Embodiment or Instance) containing the address of the target resource. Then, the browser application 20 (eg, HTML element module 210) can load the target resource according to the HTML picture element instance at the corresponding target resource address, and return the corresponding result to the HTML picture element instance to generate Module 241. The result includes an onLoad event or an onError event.

Next, in step S22, the resource health management module 240 determines whether an onLoad event or an onError event corresponding to the target resource occurs.

Specifically, the onLoad event listening module 242 of the resource health management module 240 is used to listen to onLoad events that occur through the program loading the target resource; the onError event listening module 243 of the resource health management module 240 is used to listen The onError event occurs via the program loading the target resource.

In other words, if an onLoad event occurs through the program that loads the target resource, the onLoad event listening module 242 can listen to the onLoad event and call the resource health judgment module 244 so that the resource health judgment module 244 can determine the occurrence The onLoad event; if an onError event occurs through the program that loads the target resource, the onError event listening module 243 can listen to the onError event, and call the resource health judgment module 244 to make the resource health judgment module 244 determine The onError event occurred.

In response to determining that the onLoad event occurs, step S26 is executed; in response to determining that the onError event occurs, step S23 is executed.

In this embodiment, if the target resource is a picture file, after downloading the picture file within a predetermined time, the browser application 20 will return the result of the onLoad event to the resource health management module 240. In addition, under the following conditions, the browser application 20 will return the result of the onError event to the resource health management module 240: (1) the target resource is not a picture file; (2) it cannot be displayed in the Download the target resource within a predetermined time; (3) The target resource does not exist.

It should be noted that the occurrence conditions of the onLoad event and the onError event are technologies well known to those skilled in the art and will not be repeated here.

In step S23, the resource health judgment module 244 searches for the resource timing data of the target resource via the resource timing application programming interface 230. Specifically, in order to more clearly identify that the onError event occurs as one of the above three conditions, the resource health judgment module 244 will send a query request corresponding to the target resource to the resource timing application programming interface 230 to try Query resource timing data corresponding to the target resource. After the resource timing application programming interface 230 receives the query request, the resource timing application programming interface 230 uses the resource timing module 220 to find whether there is resource timing data corresponding to the target resource.

In addition, the resource health judgment module 244 can further identify multiple values corresponding to multiple attributes of the resource timing data of the target resource through the resource timing application programming interface 230.

FIG. 4 is a schematic diagram of multiple attributes of a resource timing application programming interface according to an embodiment of the present invention.

Referring to FIG. 4, in this embodiment, the multiple attributes of the resource timing application programming interface 230 specified by W3C are shown in element C400. The multiple values of the multiple attributes are used to record multiple time points in the process of loading the target resource. For example, after loading the target resource by using the HTML picture element instance including the target resource, the resource timing module 220 may generate resource timing data 245 (also referred to as a resource timing object) corresponding to the target resource. The resource timing data may include data such as the target resource address, request start time, and return end time. At this time, the resource timing application programming interface 230 can return the found resource timing data 245 to the resource health judgment module 244 to respond to the query request of the resource health judgment module 244.

On the other hand, when the target resource does not exist at the target resource address (for example, the HTTP status code is 4XX) or the target resource has an error (for example, the HTTP status code is 5XX), the resource timing module 220 No resource timing data corresponding to the target resource will be generated, and the resource timing application programming interface 230 will not return the resource timing data 245 (for example, Google Chrome browser).

However, in another embodiment, the target resource does not exist at the target resource address (for example, the HTTP status code is 4XX) or an error occurs in the target resource (for example, the HTTP status code is 5XX), resource timing The module 220 still generates resource timing data corresponding to the target resource, and the resource timing application programming interface 230 can return the resource timing data 245 (for example, FireFox browser and Edge browser). However, in this other embodiment, the value of the target attribute of the resource timing data corresponding to the HTTP status code of 4XX or the HTTP status code of 5XX is not a normal value (for example, the value of the target attribute is NULL) .

In step S24, the resource health management module 240 determines whether the target resource is healthy or unhealthy according to the resource timing data of the target resource. The following description will be made using FIG. 3.

FIG. 3 is a flowchart of step S24 in FIG. 2 according to an embodiment of the present invention. Referring to FIG. 3, in step S241, the resource health management module 240 determines whether the resource timing data of the target resource exists. In response to determining that the resource timing data of the target resource exists (S241→Yes), step S242 is performed; in response to determining that the resource timing data of the target resource does not exist (S241→No), step S244 is performed.

As described above, if it is determined that the resource timing data exists, the resource health management module 240 will determine whether the value of the target attribute in the resource timing data of the target resource is equal to a normal value (whether it is a normal value). The target attribute of the resource timing data includes a "nextHopProtocol" attribute or a "ResponseCode" attribute. In addition, the normal value corresponding to the "nextHopProtocol" attribute is, for example, "h2" or "http/1.1", etc.; the normal value corresponding to the "ResponseCode" attribute is, for example, "2XX" (X is a positive integer or zero) . That is, the normal value corresponding to the "ResponseCode" attribute may have a range, such as "200-299". For example, assuming that the value corresponding to the "nextHopProtocol" attribute is empty, the resource health management module 240 will determine that the value corresponding to the "nextHopProtocol" attribute is not equal to the corresponding normal value, and proceeds to step S244, the resource health management module 240 will determine that the target resource is not healthy. For another example, when the target resource is not a picture file and an onError event occurs, but the corresponding resource timing data has the "nextHopProtocol" attribute that is a normal value, the resource health management module 240 will determine that the target resource is Health (S243).

For another example, assuming that the value corresponding to the "ResponseCode" attribute is "2XX", the resource health management module 240 will determine that the value corresponding to the "ResponseCode" attribute is a normal value, and proceed to step S243, the resource health management module 240 will determine that the target resource is healthy.

In addition, if it is determined that the resource timing data does not exist, the resource health management module 240 can directly determine that the target resource is unhealthy (step S244).

Please return to FIG. 2. In this embodiment, in response to determining that the target resource is healthy (S24→healthy), step S26 is performed; in response to determining that the target resource is unhealthy (S24→unhealthy), step S25 is performed.

In step S25, the resource health management module 240 records that the target resource is in an unhealthy state. Specifically, in response to determining that the target resource is unhealthy, the resource health determination module 244 calls the unhealthy resource management module 246, and the unhealthy resource management module 246 can record that the target resource is unhealthy. In addition, the unhealthy resource management module 246 can also record the target resource address, current system time, user geographic location and other suitable information, so that the resource health management module 240 or the browser application 20 can perform Corresponding subsequent processing. For example, the browser application 20 or the unhealthy resource management module 246 may report an error message to indicate that the target resource is unhealthy. In addition, in one embodiment, the resource health management module 240 may further calculate the stability of the service used by the geographic location of each user based on the address of the target resource identified as unhealthy and the geographic location of the user.

In addition, in step S26, the resource health management module 240 records that the target resource is in a healthy state. More specifically, in response to determining that the target resource is healthy, the resource health determination module 244 calls the health resource management module 245, and the health resource management module 245 can record that the target resource is in a healthy state. In addition, the health resource management module 246 can also record the target resource address, current system time and other suitable information. In particular, the health resource management module 246 can use the resource timing data of the target resource in a healthy state to calculate the delay time for downloading the target resource. For example, the health resource management module 246 may use the request start time and the return end time in the resource timing data of the target resource in the health state to calculate the request start time and the return The difference between the end times is used as the delay time.

It is worth mentioning that, as mentioned above, when the onError event occurs when the target resource is not a picture file, the general traditional method will directly respond to the occurrence of the onError event, which makes it impossible to further calculate the delay based on the resource timing data of the target resource. time. However, the embodiments of the present invention can further determine whether the target resource is healthy according to whether the target attribute in the existing resource timing data is (or equal to) a normal value, and then can be used as a healthy target resource The resource timing data is used to calculate the delay time. In this way, the embodiments of the present invention can significantly improve the problem caused by the delay time obtained by using the HTML picture element instance containing the target resource address, while retaining the cross-domain and cross-communication characteristics of the HTML picture element. , Thereby enhancing the efficiency of judging the health status and delay time of the target resource, and improving the work efficiency of the overall electronic device.

In summary, the electronic device and resource health management method provided by the embodiments of the present invention can load the target resource through the image element instance corresponding to the target resource across network domains and cross communication protocols, and correspond to the loaded target resource. The input onLoad event, onError event and resource timing data of the target event are used to determine whether the target resource is healthy, so as to perform corresponding follow-up processing on the healthy or unhealthy target resource, which can be expanded and efficiently processed across Judgment of the health status of the target resource between the network domain and the cross communication protocol.

Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
