Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment that obtains, belong to the scope of protection of the invention.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the process flow diagram of document transmission method embodiment 1 of the present invention.As shown in Figure 1, described method can comprise:
Step 101: the first electronic equipment obtains file to be transmitted, according to described file generated Base64 code to be transmitted;
Described the first electronic equipment can be the electronic equipment in Intranet, can be also the electronic equipment in outer net.When the first electronic equipment was electronic equipment in Intranet, the second electronic equipment was the electronic equipment in outer net.When the first electronic equipment was electronic equipment in outer net, the second electronic equipment was the electronic equipment in Intranet.Described the first electronic equipment can be PC, smart mobile phone, panel computer, notebook computer etc.
Need to prove that the electronic equipment in the outer net in this instructions also comprises the electronic equipment of failed cluster.
Described file to be transmitted can be the file of the types such as word document, excel form.
Base64 is one of modal coded system for transmission 8Bit syllabified code on network.The Base64 coding is used under the HTTP environment and transmits long identification information.Adopt the Base64 coding not only more brief, have not readable property simultaneously yet, namely coded data can with the naked eye directly not seen by the people.
According to described file generated Base64 code to be transmitted, detailed process can be: resolve described file to be transmitted, obtain document content information and the file type information of described file to be transmitted; According to described document content information and file type Information generation Base64 code.
In Base64 code corresponding to described file to be transmitted, comprise at least two category informations: a class is document content information, and another kind of is file type information.Document content information refers to the main contents of file, word and the picture in the word document for example, field name and numerical value in the excel table.File type information refers to the file type of file to be transmitted, is for example word document or excel table., according to document content information and file type information, can restore described file to be transmitted.
Step 102: the first electronic equipment shows described Base64 code on display unit;
Described display unit can be arranged on described the first electronic equipment, can be the basic display unit of described the first electronic equipment usually.
Step 103: the second electronic equipment obtains described Base64 code by image acquisition unit from described display unit;
Computer in take the first electronic equipment as Intranet, the second electronic equipment are that the mobile phone in outer net is example, and described image acquisition unit can be the camera on mobile phone.Can adopt the Base64 code on the described display unit of camera shooting on mobile phone, and then obtain the information that described Base64 code carries.
Step 104: the second electronic equipment regenerates described file to be transmitted according to described Base64 code.
Described the second electronic equipment regenerates the process of described file to be transmitted according to described Base64 code, be equivalent to the inverse process by file generated Base64 code to be transmitted.This process specifically can comprise: resolve described Base64 code, obtain document content information and the file type information of described Base64 code correspondence; According to described document content information and the described file to be transmitted of file type Information generation.
In sum, document transmission method of the present invention, be converted to the Base64 code by the file to be transmitted with on the first electronic equipment, obtain described Base64 code by the image acquisition unit on the second electronic equipment again, the second electronic equipment regenerates described file to be transmitted in described the second electronic equipment according to described Base64 code, be not subjected to the restriction of the factors such as network legal power in transmitting procedure, can need not the transmitting rights of intranet data is modified, just can realize the data transmission procedure between Intranet electronic equipment and external electronic device.
