Embodiment
As shown in Figure 2, the method of the invention at client software when mail server mails, according to MIME (Multipurpose Internet Mail Extensions, multipurpose internet mail expands fair agreement) agreement decodes to the coding of annex, and decoded attachment content extracted from mail preserve.
The MIME agreement permits having carried out towards the Internet email of text expanding on the basis of RFC822 agreement, so that can comprise the scale-of-two annex in mail.The MIME mail is based on an expansion of RFC822 mail, in a mail that meets the MIME agreement, the various piece of mail is the MIME section, every segment prefix is with a special head, the MIME head is according to the position in mail package, be divided into MIME information header and MIME paragraph header substantially, the MIME information header refers to the head of whole mail, and the MIME paragraph header refers to the head of each MIME section.
Field contents in the MIME information header of mail is used to show the essential information of this mail, and as sender information, date, mail title etc., the content of the MIME paragraph header of mail is used to show type, coded system of the text of mail and annex etc.Therefore can determine title, type and the coded system of annex by the field contents in the pairing MIME section of annex in the analysis mail, extract after the encoded content of annex is decoded and preserve, can realize separating from mail and annex.
As shown in Figure 3, it is as follows Email attachment to be separated the step of preservation:
Step S10, judge whether mail meets the MIME agreement, if execution in step S11 if not, finishes;
Mail from mail server, judge in the mail coding whether have MIME-Version (MIME version number) field, this field is represented the version number of the MIME agreement that mail adopts, be generally 1.0, if the coded format of mail is the MIME form, execution in step S11 if not, finishes.
Step S11, judge whether have annex in the mail, if, execution in step S12, otherwise finish; Judge the MIME section that whether has (content display mode) field that has Content-Disposition in the mail coding, if have MIME section in the mail coding with Content-Disposition field, then represent this mail to have annex, execution in step S12, otherwise finish.
The Content-Disposition field is an Optional Field, is used for representing the annex display mode of mail.The content of Content-Disposition field mainly contains " inline " and " attachment " two types, wherein " inline " to represent the display mode of Email attachment be to show that " attachment " represents the display mode of Email attachment is to show as independent annex in the row.Can also attach some optional parameter in the Content-Disposition field, mainly comprise the parameter of information such as the filename that is used to represent annex, Time Created, modification time, time for reading, file size.
Step S12, judge that whether the annex in the mail is the annex that shows separately, if, execution in step S13;
Checking the content of Content-Disposition field, is the annex that shows separately, then execution in step S13 if show described annex in the content.
Step S13, the encoded content of annex is decoded;
According to the shown type of coding of Content-Transfer-Encoding (digital coding mode) field in this MIME section the encoded content of described annex is decoded.The shown coded system of Content-Transfer-Encoding field is generally 7 encoding schemes, 8 encoding schemes, binary coding scheme, printable character encoding scheme, base64 encoding scheme, a kind of in the x-uuenconde encoding scheme.
Step S14, from mail, extract decoded attachment content and preserve.
From mail, extract decoded attachment content, represent the pairing file type of Filename parameter of attachment files name information that the annex that extracts is named according to being used in the Content-Dispositon field, the extension name of the annex that promptly extracts should be identical with the file extension in the Content-Disposition field.If in the Content-Dispositon field the Filename parameter do not exist, also can utilize the pairing file type of Name parameter in the Content-Type field that the annex that extracts is named.
After the annex that extracts named, tackling this annex preserves, for easy-to-look-up and processing later on, can be saved in similar annex in the corresponding catalogue, the standard of classification can be determined according to actual needs flexibly, both can classify to annex, and also can classify to the annex of mail, or combination is classified to annex according to the two according to the extension name of annex according to the e-mail messages in the MIME information header of mail.
The detailed process of detached accessories from mail is described below by an embodiment.
The complete encoded content of a mail is as follows:
