Abstract

Content copying method, device and system are disclosed. A first signaling is sent by a user terminal to a first server storing a target document, where the first signaling at least carries a uniform resource locator (URL) corresponding to content to be copied from a source document. The first server obtains the content to be copied from the source document according to URL in the first signaling, and adds the content to the target document. A URL or several URLs, to which the content needs to be copied corresponding, is or are once sent to a target document server. The target document server implements the steps of obtaining and adding the content of source document. The signaling between the user terminal and the server is simplified, network resource is saved, and time spent in processing is reduced.

Description

Method, device and system for copying content

The present invention relates to the field of computer identification languages, and more particularly to a method, apparatus and system for copying content. Background technique

Extensible Makeup Language Configuration Access Protocol (XCAP) is a protocol for managing extensible Makeup Language (XML) documents. Through XCAP, the client can create and modify. Delete various XML documents on the server, and also add, modify, and delete elements and attributes in the document.

The current XCAP defines three methods of management (Method): GET, PUT, DELETE, which respectively means to get, create ί 'tampering (add), delete.

It is generally convenient to use XCAP to manage a single document, but existing XCAP is inconvenient to use when managing multiple documents, especially when copying content from one document to another. . The following is an example: The user has a personal address book (Private Address Book), an XML document placed on the server (DOC, Document, specifically in the present invention, placed on the server, XML document managed by XCAP) :

DOC A's Uniform Resource Locator (URL, Uniform Resource Locator) 疋:

HTTP:〃 example . com/ resource-list/users/ sip:bill@example . com/ inde x.

DOC A is a document in XML format with the following contents:

<?xml version:" 1.0" encoding="UTF-8 " ?>

<resource-lists xmlns= "urn: ietf: arams: xml: ns: resource-lists "xmlns:xsi="http:〃www.w3.org/2001/XMLSchema-instance"><listname="privateAddressBook"> <entry uri=" sip:bill@example. com">

<display-name> Bill Doe</ display-name>

</entry>

</list>

</resource-lists>

The address book contains a contact called Bill Doe.

In addition, there is an enterprise address book (Enterprise Address Book) of the company that the user is employed in, also placed in the document B (DOC B) on the server, the company's address book contains contacts Joe and Nancy .

The URL of DOC B is:

HTTP: 〃 example.com/resource-lists/global/index. The insiders of DOC B are as follows:

<?xml version:" 1.0" encoding="UTF-8 " ?>

<resource-lists xmlns= "urn: ietf: arams: xml: ns: resource-lists " xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <list name="enterpriseAddressBook" >

<display-name>Bill Doe</ display-name>

</entry>

<display-name>Joe Smith</ display-name>

</entry>

<display-name>Nancy Gross</display-name>

</entry>

</list>

</resource-lists>

If the user needs to use the user terminal to add one or more contacts in the company address book, for example, sip:j oe@example.com and sip: nancy@example.com Add to the personal address book, as shown in Figure 1, according to the current XCAP protocol specification, can be achieved by the following steps:

1) The user terminal sends a get (GET) request to the server, and obtains information of the contact sip :j oe@example.com from the company address book;

GET

Http ://example . com/ resource-lists/ global/ index/~ /resource-lists/list[ @name="enterpriseAddressBook"]/entry[@uri="sip:joe@example.c om"] HTTP/ 1.1

Accept: application/xcap-el+xml

Host: xca . example . com

Content-Length: 0

2) The server normally returns the information of the contact sip:joe@example.com;

HTTP/1.1 200 OK

Etag: "wwhha"

Content- Type: application/xcap-el. xml

<display-name> Joe Smith </display-name>

</entry></list>

3) The user terminal sends a create (PUT) request to the server again, and adds the information of the contact sip :j oe@example.com to the document of the personal address book;

PUT

Http:〃 example . com/ resource-lists/users/ sip: bill@example . com/ index I ~ /resource-lists/list[@name="privateAddressBook"]/entry[@uri="si p:j oe @example.com"] HTTP/ 1.1

Content- Type: application/xcap-el.xml

Host: xca . example . com

<display-name> Joe Smith </display-name>

</entry></list> 4) The server returns a message that the contact was successfully added.

HTTP/1.1 201 Created

Etag: "wwhhb"

Content- Type: application/xcap-el.xml

Step 5) to step 8) Repeat steps 1) to 4), just replace the contact with sip: nancy@example.com, and complete the process of adding the contact's profile to the private address book.

The solution of the above example is to obtain and create two contact materials in the company address book one by one according to the requirements of the existing XCAP, that is, first copy the data of a contact from the source document, and add to the target document. Repeat and copy and add another contact profile. The user terminal always needs to obtain the content to be copied in the source document (company address book) from the server (the data of two contacts), and then according to the Uniform Resource Location of the content to be copied. Add it to the target document (personal address book) on the server. The process is as shown in Figure 1. A total of 8 signalings between the user terminal and the server are required to complete.

In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: If more than two or more contacts are required to be copied, the number of signaling between the user terminal and the server where the target document is located may be If you need to copy and add content between multiple documents, according to the existing XCAP specification, the operation steps of the user terminal will be cumbersome and repeated, occupying too many network resources, and the processing time will be compared accordingly. long. Summary of the invention

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a method for copying content, which is applied to copying the content in the source document of the extensible logo language document into the target document, including:

The first server storing the target document receives the first signaling sent by the user terminal, where the first signaling includes at least a uniform resource locating identifier URL of the corresponding copied content that needs to be copied from the source document;

The first server obtains the corresponding copy content from the original file and adds it to the target document according to the URL, and returns a copy success result message to the user terminal.

The foregoing first signaling may be a new signaling defined between the user terminal and the first server, or may be an extension to the signaling in the existing XCAP protocol. For a clearer and more simple description, the specific embodiment of the present invention The PUT signaling in the extended XCAP is taken as the first signaling, and the first server storing the target document is referred to as the target document server, and correspondingly, the server storing the source document is referred to as the source document server.

The following is a detailed description of several specific embodiments in conjunction with the accompanying drawings, and the background information of the two contacts joe and nancy in the company address book is copied to the personal address book as an example, and the company address book is the source. For the document, you need to add the personal address book of the contact information in the company address book as the target document.

An embodiment of the present invention provides a method for adding content replication, which copies and adds information of two contacts sip:joe@example.com>3⁄4 sip:nancy@example.com in a company address book to Personal address book. The signaling interaction process in the embodiment of the present invention is as shown in FIG. 2, and includes:

Step 201: The user terminal creates and sends an extended XCAP PUT request (hereinafter referred to as an extended PUT request) to the storage target document (personal address book) server (target document server), and the extended PUT request sequentially includes the need to The URL of the part of the source document (company address book) copied to the target document (personal address book) (data of two contacts). The information body of the extended PUT request defined by the user terminal is an XML file, and its format can be expressed by the following XML schema:

<?xml version:" 1.0" encoding="UTF-8 " ?>

<xs: schema

Xmlns:hwmp="http://www.huawei om/xcap_mutilput_extention>

Xmlns:xs=http://www.w3.org/2001/XMLSchema

<xs:sequence>

<xs: element name="content" type="hwmp: content type " maxOccurs="unbounded"/>

</xs:sequence>

</xs:complexType>

</xs:element>

</xs:schema>

The user terminal defines the format of the message body of the extended PUT request through the above XML schema, and stipulates that the message body format element is "multi_put_content", that is, the addition of multiple contents, and defines the content type of multiple contents." Content— type "is the URL. After receiving the extended PUT request, the server can follow the message body format defined by the user terminal according to the corresponding content of the multiple contents included in the extended PUT request. URL to complete the operation of copying and adding.

The user terminal sends the URL of the multiple content that needs to be copied and added to the target document server by using the extended PUT request, and the target document server completes the acquisition of the contact data in the source document, and adds Go to the target document without repeating multiple signaling between the user and the target server.

The extended PUT request sent by the user terminal to the target server is as follows:

PUT

Http:〃 example . com/ resource-lists/users/ sip: bill@example . com/ index I ~ /resource-lists/list[@name="privateAddressBook"]/entry[@uri="sip:j oe@ Example.com"] HTTP/ 1.1

Content- Type: application/x-mutil-put+xml

Require: x-mutil-put

Host: xca . example . com

<?xml version:" 1.0" encoding="UTF-8 " ?>

<multi_put— content

Xmlns="http://www.huawei.com/xcap_mutilput_extention">

<url>htt : //example . com/ resource-lists/ global/ index/― /resource-list s/list[@name="enterpriseAddressBook"]/entry[@uri="sip:joe@example. com" ]</url>

</content>

<url>htt : //example . com/ resource-lists/ global/ index/― /resource-list s/list[@name="enterpriseAddressBook"]/entry[@uri="sip:nancy@examp le.com "]</url>

</content>

</ multi_put_content>

A brief description of the above extended PUT request:

The value of the Content-Type header field in line 4 is the newly defined body type: The application/x-multi-put+xml (which may also be defined as other types, which is not limited by the embodiment of the present invention) indicates that the type of the content of the extended PUT request is the newly defined media type.

In the above extended PUT request, the standard header field "Require" is used to extend the PUT request, an extension condition "x-mutil-put" is defined, and the Require header i or value is set in the fifth line. X-mutil-put; The user terminal sends a request to the server through the above "Require" header i, requests the server side to support the extended PUT request, and performs an extended PUT request to define a plurality of content addition functions. In the actual application process, you can also use the custom header field to expand the way, for example, replace the "Require" header field with the "X-extension" custom header field. When expanding the PUT request, "X-extension "The header i or the corresponding value is especially x-mutil-put.

In the above extended PUT command, the URLs of the two contacts that need to be copied and added to the personal address book are included:

In the above extended PUT command, the order includes the URL of the first contact sip :j oe@example.com and the second contact sip: nancy@example.com:

Http ://example . com/ resource-lists/ global/ index/~ /resource-lists/list[ @name="enterpriseAddressBook"]/entry[@uri="sip:joe@example.com"] is the first The URL of the contact sip :j oe@example.com;

Http ://example . com/ resource-lists/ global/ index/~ /resource-lists/list[ @name= " enterprise AddressBook" ] /entry [ @uri= " sip : nancy @example . co m"] is Second contact sip: URL of nancy@example.com„

The above-mentioned extended PUT request includes the URLs of the two contact materials that need to be copied and added to the personal address book (of course, the actual situation may also include more than two or more, which is not limited by the embodiment of the present invention), and the target The document server sequentially acquires and adds the content to be copied through the URL of the desired copy content in the extended PUT request.

The target document server confirms that the user terminal sends the extended PUT request through the Require header field value in the extended PUT request, instead of the PUT request under the existing XCAP, and processes according to the manner defined by the extended PUT request. That is, according to multiple The URL of the content to be copied is copied and added to the target document; Step 202: After the target document server receives and confirms the PUT request for the extension, the first contact sip included in the extended PUT request is : j oe @example . com URL, determine the company address containing the contact information, this document is also on the target document server, and then the target document server performs step 203;

Step 203: The target document server obtains the material information of the first contact sip:joe@example.com directly from the company address book according to the URL of the first contact; Step 204, the target document server sends the information to the personal address book. Adding the information of the first contact sip: j oe @example . com obtained in step 203;

Step 205: The target document server determines, according to the URL of the second contact sip:nancy@example.com in the extended PUT request, that the information of the second contact is also in the company address book where the first contact is located. Then, the target document performs step 206; Step 206: The target document server obtains the data information of the second contact sip: nancy@example.com directly from the company address book according to the URL of the second contact;

Step 207: The target document server adds the information of the contact sip: nancy@example.com obtained in step 206 to the personal address.

If you need to add the third and fourth contacts or even more contacts in the above company address to the above personal address book, you only need to repeat steps 202 to 203 above.

Step 208: The target document server returns a result message that the user terminal has successfully copied. If multiple contacts Joe and Nancy are in the same company address book, and the company address book is not on the same server as the private address book, that is, the company address book is on another source document server, the flow is as shown in FIG. , including:

Step 301: The user terminal creates and sends an extended PUT request to the target document server where the target document (personal address book) is located;

Step 302: After receiving the extended PUT request, the target document server copies the URL of the added first contact data according to the extended PUT request, and determines that the company address book is located on the source document server, that is, Company address book and personal address book Not on a server;

Step 303: The target document server sends a GET request to the source document server, requesting the information of the first contact joe in the company address book;

Step 304: The source document server returns the data information of the first contact joe; Step 305: The target document server adds the data of the first contact to the personal address book;

Step 306: The target document server determines, by using the URL of the second contact Nancy data in the extended PUT request, that the company address book is located on the source document server. Step 307: The target document server requests to obtain the second address of the company address book. Information of contacts;

Step 308: The source document server returns the data information of the second contact nancy; Step 309: The target document server adds the acquired second person's data to the personal address book;

Step 310: The target document server returns a successfully copied result message to the user terminal.

As shown in Figure 4, if the two contacts joe and nancy need to be added belong to two different company address book A and company address book B, and the company address book A is the same as the personal address book (target document). On the target document server, the company address book B is on another source document server. Now you need to copy and add the data of the two contacts to the personal address book. The specific process is shown in Figure 4.

When the user terminal sends the extended PUT request to the target document server, the target document server obtains the address of the company address A on the local server through the URL of the first contact joe in the extended PUT request, and directly obtains the company address. The information of the contact in this A is added to the personal address book (the specific steps are similar to steps 202 to 203 in Embodiment 1;).

The target document server sends a GET request to the source document server through the URL of the second contact nancy in the extended PUT request, and obtains the profile information of the contact, and then adds it to the local personal address book (target document) (specific steps) Similar to step 302 to step 305 in Embodiment 2; After the contact data that needs to be added has been added, the result message that the user terminal has successfully copied is returned.

According to the method for copying content between XML documents according to the above embodiment, the embodiment provides a content copying system, and the content applied to the source file of the extensible markup language is copied into the target document, as shown in FIG. 5. As shown, the method includes: a user terminal and a first server, wherein:
