具体实施方式Detailed ways
为使本发明的目的、技术方案及优点更加清楚明白，以下参照附图并举实施例，对本发明做进一步详细说明。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.
本发明的整体思路是：本地用户计算机通过网络与网页传输服务器(HTTP服务器)、FTP服务器和数据库服务器分别建立起网络连接。本地用户通过HTTP服务器获得ASP(Active Server Page)界面，通过该界面，用户可直接将FTP服务器上所存储的文件直接下载到本地计算机，并预览所选文件的具体内容，或用户在数据库服务器上浏览所选文件的属性信息，以确定是否预览所选文件的具体内容，再将FTP服务器上的存储的文件下载到本地计算机并预览。The overall idea of the present invention is: the local user computer establishes network connections with the web page transmission server (HTTP server), FTP server and database server respectively through the network. The local user obtains the ASP (Active Server Page) interface through the HTTP server. Through this interface, the user can directly download the file stored on the FTP server to the local computer, and preview the specific content of the selected file, or the user can download the file on the database server. Browse the attribute information of the selected file to determine whether to preview the specific content of the selected file, and then download the stored file on the FTP server to the local computer and preview it.
图1所示为应用本发明的本地用户预览网络资源的数据流向示意图。本地用户计算机通过WinInet(Windows Internet)及相关技术与HTTP服务器、FTP服务器和数据库服务器分别建立起网络连接，并通过HTTP服务器获得资源管理界面，即ASP界面，该界面中含有FTP服务器上所存储文件的路径信息。用户通过ASP界面所提供的预览控件(ActiveX控件)，可直接下载并预览FTP服务器上所存储文件的具体内容，或者用户可先在数据库服务器上浏览所选文件的属性信息，如文件大小或文件类型等，以确定是否预览所选文件的具体内容，再将FTP服务器上的存储的文件下载到本地计算机并进行预览。其中，本地用户计算机在下载FTP服务器上所存储的文件时，可同时应用预览控件预览已从FTP服务器上下载的文件，即本地计算机可进行下载与预览的异步操作。FIG. 1 is a schematic diagram showing the data flow of a local user previewing network resources applying the present invention. The local user computer establishes network connections with the HTTP server, FTP server and database server through WinInet (Windows Internet) and related technologies, and obtains the resource management interface through the HTTP server, that is, the ASP interface, which contains files stored on the FTP server. path information. Through the preview control (ActiveX control) provided by the ASP interface, the user can directly download and preview the specific content of the file stored on the FTP server, or the user can first browse the attribute information of the selected file on the database server, such as file size or file size. Type, etc., to determine whether to preview the specific content of the selected file, and then download the stored file on the FTP server to the local computer and preview it. Wherein, when the local user computer downloads the file stored on the FTP server, the preview control can be used to preview the file downloaded from the FTP server at the same time, that is, the local computer can perform asynchronous operations of downloading and previewing.
ASP界面可以继承本地用户计算机的环境属性，如字体、背景色等，保证了所预览的界面与本地用户所设置的界面的一致性。The ASP interface can inherit the environmental attributes of the local user's computer, such as fonts, background colors, etc., ensuring the consistency between the previewed interface and the interface set by the local user.
预览控件查找FTP服务器上所存储的文件时，可根据用户的要求采用未编码的设置预览文件路径(SetPreviewFilePath)的方法或已编码的设置预览文件路径(SetPreviewFilePathEx)的方法。其中，SetPreviewFilePath方法中含有待预览文件路径和资源文件存放类型两个参数，SetPreviewFilePathEx方法中含有经编码的待预览文件路径和资源文件存放类型两个参数。当待预览文件在本地时，其待预览文件路径为物理路径或经编码的物理路径，当待预览文件在网络服务器上时，其待预览文件路径为URL(Unique Resource Location)或经编码的URL。资源文件存放类型描述的是文件的存放方式，When the preview control searches for files stored on the FTP server, it can use the uncoded method of setting the preview file path (SetPreviewFilePath) or the coded method of setting the preview file path (SetPreviewFilePathEx) according to the user's requirements. Among them, the SetPreviewFilePath method includes two parameters of the file path to be previewed and the storage type of the resource file, and the SetPreviewFilePathEx method includes two parameters of the encoded file path to be previewed and the storage type of the resource file. When the file to be previewed is local, the path of the file to be previewed is a physical path or an encoded physical path; when the file to be previewed is on a network server, the path of the file to be previewed is URL (Unique Resource Location) or an encoded URL . The resource file storage type describes the storage method of the file.
例如，当用户选中某一文件并要求采用SetPreviewFilePathEx方法进行文件预览时，则经编码的待预览文件路径和资源文件存放类型将作为两个参数传送给预览控件，预览控件根据SetPreviewFilePathEx中的资源文件存放类型参数判断出该用户所选的待预览文件存放于本地计算机中还是网络文件服务器中，如果待预览文件存放于网络服务其中，则预览控件根据SetPreviewFilePathEx中的URL得到待预览文件的网络路径，并将该待预览文件下载到本地计算机后即可进行预览。应用SetPreviewFilePath方法，与SetPreviewFilePathEx方法类似。For example, when the user selects a file and requests to use the SetPreviewFilePathEx method to preview the file, the encoded file path to be previewed and the storage type of the resource file will be sent to the preview control as two parameters, and the preview control will store the file according to the resource file in SetPreviewFilePathEx. The type parameter determines whether the file to be previewed selected by the user is stored in the local computer or the network file server. If the file to be previewed is stored in the network service, the preview control obtains the network path of the file to be previewed according to the URL in SetPreviewFilePathEx, and After the file to be previewed is downloaded to the local computer, it can be previewed. Apply the SetPreviewFilePath method, which is similar to the SetPreviewFilePathEx method.
