Detailed description of the invention
For making object, technical scheme and the advantage of the embodiment of the present invention clearer; below in conjunction with the accompanying drawing in the embodiment of the present invention; technical scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is the present invention's part embodiment, instead of whole embodiment, based on the embodiment in the present invention; the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of method of data interaction, and the method can comprise the following steps:
S0: the configuration information that sets in advance PDF list;
S1: according to described configuration information, generate the mutual pdf document with form controls;
S2: described mutual pdf document is sent to client;
S3: receive the mutual pdf document that carries the interaction data receiving by described form controls that described client is sent;
S4: resolve the mutual pdf document that carries described interaction data, obtain described interaction data.
The embodiment of the present invention provides a kind of method of data interaction, user can add form controls by configuration information as required in mutual pdf document, to meet the requirement of user to various file formats, receive the interaction data of outside input by form controls, to meet the demand of with no paper office, improve the efficiency of with no paper office.
In order to facilitate user to handle official business with no paper at all, in a kind of possible implementation, the method also comprises: be application/pdf by the form of HTTP heading, so that described client, according to the form of described HTTP heading, is opened described mutual pdf document by browser.
In this implementation, be application/pdf by the form of HTTP heading is set, make user can open mutual pdf document by the direct singles of browser in the time handling official business with no paper at all, this mutual pdf document is operated, without processing by special software.
In order to make mutual pdf document can meet user's various demand datas, in a kind of possible implementation, described S1, also comprises: described form controls is set to the form controls of FDF form; Described S3, comprising: the mutual pdf document of the interaction data that carries FDF form that reception client is sent.
Be implementation by this, form controls is set to the form controls of FDF form, makes form controls in mutual pdf document can receive the file of FDF form, can receive the file of picture, certificate and so on. In the time that this mutual pdf document can receive various file type, can make with no paper office convenient efficient, can be suitable for various scenes.
In addition, in step S1, all right: described form controls is set to the form controls of HTMLFORM form. By the form controls of HTMLFORM form, mutual pdf document can receive various text datas, can increase the processing speed of mutual pdf document.
The method of a kind of data interaction that the embodiment of the present invention provides, can support filling in online of mutual pdf document, realizes online data interaction. Server generates above-mentioned mutual pdf document, and send to client, client is opened this mutual pdf document by browser, user directly fills in data by browser in the form controls of mutual pdf document, after having filled in, mutual pdf document is submitted to server, namely the mutual pdf document that carries interaction data is sent to server by client, server is resolved, and obtains interaction data.
In addition, in order to ensure the safety of interaction data, can sign to mutual pdf document. Particularly, the method also comprises:
Pre-configured server certificate;
After S1, before S2, also comprise:
According to described server certificate, described mutual pdf document is signed;
Client is receiving after mutual pdf document, need to carry out signature verification, particularly, comprising:
In advance in server certificate described in client configuration;
Client is according to described server certificate, signature to described mutual pdf document is verified, when by checking, receives the interaction data of user's input by form controls, when not by checking, do not allow to carry out data interaction by this mutual pdf document and server.
This implementation can realize by setting in advance Javascript script.
User may not fill in interaction data online sometimes, in order to be user-friendly to, need to provide the mutual pdf document interactive mode of off-line, in a kind of possible implementation, before described S2, also comprises:
Receive the request of the described mutual pdf document of download that described client sends, set up and the session of client according to described request;
In described mutual pdf document, add Hidden field, described Hidden field comprises: the session information that carries out session with client;
Described S3, also comprises:
Obtain the described session information in the Hidden field in described mutual pdf document, according to described session information, set up the session with client.
By this implementation, the mutual pdf document needing by client downloads, comprises Hidden field in this mutual pdf document, and this Hidden field comprises session information. After user has filled in by form controls in mutual pdf document, need to mutual pdf document be sent to server by client, this is, server just can be according to the session information in the Hidden field in mutual pdf document, re-establish the session with client, context environmental when regenerating user and downloading mutual pdf document, continues to carry out session with client, has continued follow-up work. The session information here can comprise: session id, Session Time etc.
By above-mentioned implementation, can realize the off-line of mutual pdf document and fill in. In addition, can, by following implementation, ensure the safety of the data interaction in this process, the method also comprises:
In advance at client configuration server certificate and client certificate, in advance in server configuration client certificate and server certificate;
After S1, before S2, also comprise:
According to described server certificate, described mutual pdf document is signed;
Client, according to described server certificate, is verified the signature of described mutual pdf document, when by checking, confirms to use described mutual pdf document, when not by checking, again downloads mutual pdf document from server.
Before uploading at user end to server the mutual pdf document that carries interaction data, need to sign to this mutual pdf document, particularly, comprise:
Client is according to described client certificate, and the mutual pdf document that carries interaction data to passing is signed;
Server receives after described mutual pdf document, according to described client certificate, the signature of described mutual pdf document is verified, after checking, trusts this mutual pdf document, can perform step S4, during not by checking, distrusts this mutual pdf document.
In addition, in client, can be in AdobeReader configuration server certificate, in the time opening mutual pdf document by AdobeReader, mutual pdf document is verified. Can also be in client configuration: CA certificate, user certificate, by these certificates, mutual pdf document is verified.
In a kind of possible implementation, described S2, comprising: the example of the PdfStamper class by iText writes described mutual pdf document to ServletOutputStream.
By this implementation, mutual pdf document can be transferred to client.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
