Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1A is a flowchart of a mail parsing method according to an embodiment of the present invention, which is applicable to any mail client performing mail forwarding and receiving. The mail parsing method provided in this embodiment may be executed by the mail parsing apparatus provided in the embodiment of the present invention, and the apparatus may be implemented in a software and/or hardware manner and integrated in a server executing the method, where the server executing the method in this embodiment may be any one of a tablet computer, a desktop computer, a notebook computer, a mobile phone, and other intelligent devices including a mail client. Specifically, referring to fig. 1A, the method may include the steps of:
s110, when receiving the mail, determining each attachment block information in the MIME mail data according to the boundary mark in the MIME mail data.
The existing mail data generally follows a certain format requirement to analyze and extract information such as a sender, a receiver, a subject, an attachment and the like from the mail data, and the basic format and the specific details of the mail data are respectively defined by the standard format RFC 822 and the MIME protocol of the e-mail. The RFC 822 standard can only send basic ASCII text information, while the MIME protocol can also add a variety of different rich texts, in-line pictures, attachments, etc. in the mail, with different character sets and encoded mail contents. At this time, mail data defined by the MIME protocol in which a variety of different encoded files can be attached is MIME mail data. Specifically, MIME mail data can be composed of a mail header and a mail body. The mail body may include at least one of plain text, hypertext, embedded resources (such as pictures embedded in the hypertext), or a combination of attachments, so as to represent specific contents in the mail, and at this time, the mail body may specifically represent each content in the mail by a plurality of segments including a segment header and a segment body, respectively. It should be noted that the specific content of the mail contained in the mail body in this embodiment can be distinguished by the mail type in the mail header.
Further, the boundary identifiers in the MIME mail data can be used to distinguish and determine different mail contents in the MIME mail data, such as plain text, hypertext, inline pictures and attachments, etc. The boundary identifier can be customized by a user according to specific mail content, and the boundary identifier can distinguish each mail content from a plurality of mail contents and determine the specific position of a field corresponding to each mail content in a mail body. Specifically, the boundary identifier in this embodiment may be determined by boundary field information in the MIME mail data. The boundary identifier may include the mail type in the mail header, so as to determine the different mail contents contained in the MIME mail data.
Optionally, in order to improve the performance of mail parsing, the time for loading the mail on the disk needs to be reduced, in this embodiment, when the mail is received, first determining that the received mail is a MIME mail, and then preprocessing the MIME mail in the process of receiving the MIME mail, that is, searching each boundary field information in the MIME mail data, to determine each corresponding boundary identifier, and determining a boundary identifier corresponding to the attachment block information in all the boundary identifiers, to specifically determine each attachment block information in the MIME mail data. Wherein, each attachment block information can include all attachments carried in the received MIME mail data. Specifically, the receiving of the mail in this embodiment may be receiving a new mail sent by another account, or directly opening a new mail that has not been opened before the current mail client in the desktop, for example, a mail copied by the local user from another user and not opened by the local mail client.
Further, the boundary identifier in this embodiment may include a boundary type and a boundary parameter. The boundary type can determine the specific mail content in the MIME mail data, which is equivalent to the mail type in the mail header, and when the mail is received, whether the MIME mail data includes the attachment can be directly determined by analyzing the mail type in the mail header. Meanwhile, the boundary parameter can determine the specific position of the field corresponding to each attachment block in the MIME mail data, thereby directly determining the information of each attachment block in the MIME mail data.
Specifically, the boundary Type in the boundary identifier, i.e., the mail Type, may be determined by a Content-Type field in the mail header, where the mail Content includes only plain text, the Content-Type field is a text/plane representation, and where the mail Content further includes various mixed other contents, the Content-Type field is a multipart Type, including a multipart/mixed Type, a multipart/related Type, and a multipart/Alternative Type. The multipart/mixed type represents the information of the first-level block, and an attachment exists in MIME mail data; multipart/related type represents secondary block information, there are embedded resources in MIME mail data, such as pictures embedded in hypertext, etc.; the multipart/alternate type indicates that there are multiple text blocks in the MIME mail data.
Specifically, the boundary parameters in the boundary identifier may be specific boundary parameters respectively corresponding to the mail types in the mail headers, and the corresponding mail content positions may be determined in the mail body according to the specific boundary parameters. For example, upon receiving a mail, the mail header in the MIME mail data includes:
“Content-Type:multipart/mixed；
boundary＝"----＝_Part_217443_152692695.1495196666093"”；
the boundary type is multipart/mixed, which indicates that there are attachments in the MIME mail data, and the boundary parameter is "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (217443- -152692695.1495196666093", and the specific information of each attachment can be determined in the mail body according to the boundary parameter.
If the mail header in the MIME mail data includes:
“Content-Type:multipart/alternative；
boundary＝"----＝_Part_214835_1240140699.1495194691872"”；
the boundary type is multipart/alternative, which indicates that a text block exists in MIME mail data, and the boundary parameter is "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -214835- -1240140699.1495194691872", and may determine the specific information of the text block in the mail body according to the boundary parameter.
On the basis of the above embodiment, as shown in fig. 1B, determining each attachment block information in the MIME mail data according to the boundary identifier in the MIME mail data may include:
s111, at least one boundary identification in the MIME mail data is obtained.
Specifically, the MIME mail is preprocessed, that is, each boundary field information is found in the MIME mail data, so as to determine each corresponding boundary identifier. When the MIME mail data includes a plurality of items of specific mail contents, a plurality of different boundary identifiers may be set, respectively corresponding to different mail contents. When receiving the mail, at least one boundary identifier in the MIME mail data is obtained first, and the boundary Type and the boundary parameter in the boundary identifier, namely the Content-Type field and boundary field information.
And S112, if the attachment exists in the MIME mail data according to the boundary type in each boundary identifier, determining the information of each attachment block according to the boundary parameters in each boundary identifier corresponding to the attachment.
Specifically, after at least one boundary identifier is obtained, whether the Content-Type field corresponding to the boundary Type in each boundary identifier has multipart/mixed Type information is judged firstly, if yes, it is determined that an attachment exists in the MIME mail data, at this time, a boundary parameter in each boundary identifier corresponding to the attachment, that is, a boundary field parameter corresponding to the multipart/mixed field is obtained, and each attachment block information is determined in the mail body according to the boundary field parameter.
Illustratively, when the boundary field parameter corresponding to the multipart/mixed field in the mail header of the MIME mail data is "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -217443- -152692695.1495196666093", the field information included in the boundary field, that is, each attachment block information, is determined only in the mail body. For example: in the body of the mail
“------＝_Part_217443_152692695.1495196666093
Content-Type:text/plain；name＝"first1.txt"
Content-Transfer-Encoding:base64
Content-Disposition:attachment；filename＝"first1.txt"
MTIzNA＝＝
------＝_Part_217443_152692695.1495196666093
Content-Type:text/plain；name＝"first2.txt"
Content-Transfer-Encoding:base64
Content-Disposition:attachment；filename＝"first2.txt"
MTIzNA＝＝
------＝_Part_217443_152692695.1495196666093--”；
Wherein two attachments are present in the body of the mail piece and the content is designated for encoded transmission by means of base 64. In addition, each accessory block information in the present embodiment may include: the information of the name and the size of each attachment block can be obtained in advance by analyzing the information of each attachment block, so as to determine the specific information of each attachment block in the MIME mail data for subsequent use.
And S120, when receiving a mail analysis instruction acted by a user, analyzing the other mail information except the attachment block information in the MIME mail data according to the mail analysis instruction.
When a user needs to open a mail, the mail client receives a mail analysis instruction acted by the user, wherein the mail analysis instruction can indicate a specific name of the opened mail or a corresponding command when the mail is automatically analyzed and relevant information of the mail is extracted, so that the corresponding specified mail is analyzed.
Optionally, when receiving a mail parsing instruction acted by a user, the mail client may determine whether a mail corresponding to a designated opening is preprocessed according to the mail parsing instruction, and after determining corresponding attachment block information in the MIME mail data, filter the attachment block information in the MIME mail data, only load and parse other mail information except the attachment block information, and do not parse the attachment blocks, thereby improving mail loading and parsing efficiency. Wherein, the rest mail information may include the text information and the inline picture in the MIME mail data.
And S130, generating mail display data according to the analyzed other mail information and the analyzed attachment block information.
Specifically, after analyzing the rest of the mail information except the attachment block information in the MIME mail data, it is necessary to display the analysis result for the user, and generate mail display data according to the text or picture information in the analyzed rest of the mail information and the attachment block information that is not analyzed, where the mail display data may be displayed through a mail page, or the mail display data after the analysis may be stored for subsequent use. The mail display data defines the content of the MIME mail, the mail text, the in-line pictures, the carried attachment blocks and the like. Alternatively, only the names and sizes of the attachment blocks may be displayed by previously parsing the names and sizes of the attachment blocks, and the specific content of each attachment block is not parsed.
According to the technical scheme, when the mail is received, the attachment block information in the MIME mail data is determined, and when the mail is analyzed, only the rest mail information except the attachment block information is analyzed, so that time consumption and memory occupation in the mail loading and analyzing process are reduced, the mail analyzing performance is improved, and the user experience is improved.
Example two

s210, when receiving the mail, determining each attachment block information in the MIME mail data according to the boundary mark in the MIME mail data.
And S220, storing the information of each attachment block into an attachment table.
Specifically, after determining the start position, the attachment block length, and the attachment block name of the attachment block in each piece of attachment block information, the corresponding piece of attachment block information may be stored in the attachment table as a data record. The attachment table can be stored in a mode of referring to a data table in a database, and a keyword identifier is set for each data record, so that corresponding attachment block information can be searched in the attachment table in time when the corresponding attachment block needs to be analyzed subsequently, and the analysis efficiency is improved.
And S230, when receiving a mail analysis instruction acted by a user, analyzing the other mail information except the attachment block information in the MIME mail data according to the mail analysis instruction.
And S240, determining text information and/or inline picture information in the mail and a corresponding display position in the mail display data according to the analyzed rest mail information.
In this embodiment, the remaining mail information in the MIME mail data, except for the attachment block information, may include text information of the mail body and/or inline picture information, where the text information may include plain text, hypertext, and the like. Optionally, when displaying the analyzed remaining email information, text information and/or inline picture information in the email and a corresponding display position of the text information and/or inline picture information in the email display data need to be determined.
And S250, displaying the text information and/or the inline picture information at the corresponding display position, and generating mail display data by combining the information of each attachment block.
Optionally, when the corresponding display position of the text information and/or the inline picture information in the email page is determined, the text information and/or the inline picture information may be displayed at the corresponding display position in the email display data, and corresponding email display data is generated according to each piece of attachment block information determined in the MIME email data, in combination with the name and size of the attachment block of each attachment block, for displaying an email parsing result.
S260, judging whether an accessory analysis instruction acted by a user is received, and if so, executing S270; if not, go to step S280.
Specifically, after the mail analysis result is displayed for the user on the mail display data, if the user needs to check the corresponding attachment block, the corresponding attachment block is analyzed by double-clicking the name of the corresponding attachment block on the mail display data, and when the user double-clicks the attachment block on the mail display data, the mail client receives an attachment analysis instruction acted by the user, so that the corresponding attachment block is analyzed.
S270, acquiring target attachment block information corresponding to the attachment analysis instruction in the attachment table, and analyzing the target attachment data in the MIME mail data based on the target attachment block information.
Specifically, when an attachment analysis instruction acted by a user is received, target attachment data required to be analyzed by the user can be determined according to the attachment analysis instruction, a corresponding data recording position is determined in an attachment table in time through a keyword identifier corresponding to the target attachment data, so that target attachment block information stored in the attachment table is searched, information such as a starting position, an attachment block length and an attachment block name of a target attachment block in MIME mail data is determined, corresponding MIME field information of the target attachment data in the MIME mail data is read according to the starting position of the target attachment block in the MIME mail data, and the MIME field information corresponding to the target attachment data is decoded according to a corresponding transmission coding mode in a field to obtain an analyzed target attachment. Optionally, the parsed target attachment data may be stored in a temporary directory and then opened, so as to display the corresponding target attachment content for the user.
And S280, ending the process.
