Embodiment 1

[0052] see figure 1 , this embodiment provides a method for asynchronous cross-domain transmission of XML data, including:

[0053] 101: Convert the Extensible Markup Language XML request data into a request string;

[0054] 102: Send an asynchronous cross-domain data request to the cross-domain server through an external file reference link, where the asynchronous cross-domain data request carries a request string.

[0055] Among them, the external file reference link can be 标签。

[0056]参见图2，本实施例提供了一种异步跨域传输XML数据的方法，包括：

[0057]201：接收跨域客户端发送的异步跨域数据请求，并获取异步跨域数据请求中携带的请求字符串；

[0058]202：根据请求字符串，获取可扩展标记语言XML响应数据；

[0059]203：将XML响应数据转换成响应字符串；

[0060]204：以jsp格式向跨域客户端返回异步跨域数据响应，该异步跨域数据响应携带响应字符串。

[0061]本实施例通过将XML格式的数据转换成字符串，将字符串以特定形式在客户端及其跨域服务端之间直接传输，无须中转代理，降低了XML数据传输时延。

[0062]参见图3，下面结合具体实例介绍上述异步跨域传输XML数据的方法。

[0063]301：客户端将XML请求数据转换成请求字符串；

[0064]302：可选的，客户端将该请求字符串保存在URL(Uniform Resource Locator，统一资源定位符)参数中；

[0065]303：客户端通过外部文件引用链接向跨域服务端发送异步跨域数据请求，该异步跨域数据请求携带请求字符串；

[0066]其中，外部文件引用链接可以为标签。

Abstract

The invention discloses a method, a client and a server for asynchronous cross-domain transmission on extensible markup language (XML) data, which belong to the field of data transmission. For the client, the method comprises the following steps: converting XML request data into a request character string; sending an asynchronous cross-domain data request to a cross-domain server through external file reference interlinkage, wherein the request character string is carried by the asynchronous cross-domain data request. For the server, the method comprises the following steps: receiving the asynchronous cross-domain data request sent by a cross-domain client, and acquiring the request character string carried in the asynchronous cross-domain data request; according to the request character string, acquiring corresponding XML response data; converting the XML response data into a response character string; and returning an asynchronous cross-domain data response to the cross-domain client in a Java server page (jsp) format, wherein the response character string is carried by the asynchronous cross-domain data response. In the method, the client and the server for the asynchronous cross-domain transmission on the extensible markup language (XML) data, through converting the data of an XML format into the character string, and directly transmitting the character string between the client and the cross-domain server thereof in a specific mode without a transfer agent, the time delay of XML data transmission is reduced.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method for asynchronous cross-domain transmission of XML data, a client and a server. Background technique [0002] The data required by the network platform are often scattered and stored under different domain names. For example, the data required by the Paipai Information Center in the early stage of development are stored under different domain names. Synchronously fetching data stored on servers under other domain names through the server under the current domain name has a great impact on the performance of the server interface and request timeout. [0003] In order to solve the above problems, a scheme in which the client directly sends a request to obtain data under the third-party security domain can be adopted. However, the client can only perform asynchronous cross-domain data transmission and requests for json (JavaScript Object Notation) or jsp (Java Server Pages)...
