Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
Embodiments provide the script insertion method in a kind of web application, as shown in Figure 1, the script insertion method process flow diagram in a kind of web application that Fig. 1 provides for the embodiment of the present invention, described method comprises:
S101: after the web request receiving client transmission, judges whether carry static file mark in described web request.
S102: if do not carry static file mark in described web request, then determine the flow data returned for described web request.
S103: in described flow data, the key word that search is preset.
S104: by described key word, locates script insertion position in described flow data.
S105: described script is inserted into the described script insertion position in described flow data, and the flow data inserting script is back to described client.
In S101, user sends web request by the client being provided with browser to web application server, wherein, carries URL (UniformResourceLocator, URL(uniform resource locator)) in described web request.After described web application server receives described web request, judge in described web request, whether to carry static file mark.Concrete, when to carry URL in described web request be such as end up for .js .css .jpg .jpeg .gif .png or .bmp, described web application server determines that carrying static file in this web request identifies.
In the present embodiment, for the web request of carrying static file mark, do not perform the insertion of script.
In S102, if described web application server is determined not carry static file mark in described web request, then for described web request, determine the flow data corresponding with it.Concrete, it according to the web page resources of the URL consumer positioning request of carrying in described web request, and is back to client with the form of flow data by described web application server.
In S103, after the flow data returned for described web request determined by described web application server, described web application server searches for default key word in this flow data.Such as, when the script that will insert is JavaScript script, the key word preset is then </HEAD> or </head>, </BODY> or </body>.Concrete, in the flow data determined, search for the above-mentioned key word determined.
In addition, in practical operation, there is different reading manners in the flow data for various flows type.So the present embodiment, before stream data carries out the search of key word, first judges the stream type of described flow data.Concrete, when described flow data is character stream, in described flow data, the key word preset by chracter search.When described flow data is byte stream, in described flow data, the key word preset by byte search.
In S104, described web application server, after determining the position of preset keyword in described flow data, according to the position of described key word, determines the script insertion position in described flow data.In a kind of implementation, if script is javaScript script, then described web application server is in described flow data, after determining the position at described key word place, the previous position adjacent with the position at described key word place is defined as script insertion position.That is, the position of before key word is defined as the insertion position of javaScript script by described web application server.
In S105, determine the script insertion position in described flow data when described web application server after, the script that can realize specific function write in advance is inserted into the described script insertion position in described flow data, and the flow data inserting described script is back to described client.Wherein, common Scripting language comprises Scala, JavaScript, VBScript, ActionScript, MAXScript, ASP, JSP, PHP, SQL, Perl, Shell, python, Ruby, JavaFX, Lua, AutoIt etc.In addition, specific function can be realized by compile script, write as utilized JavaScript and can realize capturing user's browsing pages data, find the function of page access bottleneck.
In practical application, because the total length inserting the flow data of script increases, so, before the flow data inserting script is back to client, adjust the length parameter in this data stream, to record the length of this data stream truly.
Embodiments provide a kind of method of carrying out script insertion in the web application completing deployment, the method carries out script insertion based on the mode of flow data.Because web application server is when loading User Page resource, be adopt the mode of data stream and client to carry out data transmission.So the embodiment of the present invention is tackled the flow data that web application server sends to client, in this flow data, insert script.After client receives the flow data inserting script, carry out page rendering by web container, just can show with the page inserting script.The script inserted in the page is sightless concerning user, and namely user cannot feel to insert script in the page, so script insertion method provided by the invention is very little for the impact of user's browsing pages.
The embodiment of the present invention additionally provides the script insertion method in another kind of web application, and described method is encapsulated as java probe.In practical application, this java probe is installed on each web application server in advance, and can determine concrete stream data processing method according to the model of each web application server.
In practical application, owing to being packaged with the method that the script that can realize in web application inserts in java probe, so for the user wanting the script insertion realized in web application, it uniquely needs the thing done to install java probe exactly in web application server.That is, this mode does not need user to be those skilled in the art, can realize the insertion of script in web application yet.
The embodiment of the present invention additionally provides the script insertion apparatus in a kind of web application, the script insertion apparatus structural representation in a kind of web application provided for the embodiment of the present invention with reference to figure 2, Fig. 2.Described device comprises:
