Description

Method for importing personal mail into domestic mailbox system Technical Field The invention relates to the technical field of data migration, in particular to a method for importing personal mails into a domestic mailbox system. Background Under the background of enterprise digital transformation and the promotion of the credit creation industry, the migration of data in the existing mail system to the credit creation mailbox has become one of the core links of enterprise credit creation transformation. At present, some mail data migration tools and methods exist in the industry and are used for realizing the transfer of mail data from an original system to a target mail creation box, but the prior art gradually exposes a plurality of defects when facing to an enterprise-level application scene. Firstly, the enterprise-level user is large in scale, the mail data volume is huge, the existing migration tool mostly adopts a single-thread processing mode, the concurrence capability is insufficient, the migration efficiency is low, the severe requirements of enterprises on migration periods are difficult to meet, secondly, aiming at multilingual mails commonly existing in a mail system, the prior art lacks a unified and reliable coding and checking mechanism, the problems of messy codes and distortion of mail heads, text or accessory contents caused by incompatibility of codes often occur, moreover, the existing migration scheme is insufficient in suitability for a problem mail redirection scene, an effective unique identification mechanism is not established, the situation that successfully imported mails are repeatedly imported is easy to occur, the redundancy of target mail data is caused, in addition, the existing tool mostly adopts unified processing logic to cope with different types of mail data, the format difference of common mails, schedule mails and the like is obvious, format conversion errors are easy to occur, the data cannot be normally displayed or used in the mail boxes after migration is caused, finally, the existing migration process monitoring and recording mechanism cannot migrate, the detailed feedback of the problem is simple, the fault information can not be easily fed back, the key node positioning is difficult to accurately and the positioning of the whole mail is difficult to be difficult. The defects in the prior art lead to the migration work of enterprise-level mail data to an created mail box to face many challenges such as long period, poor data accuracy, more redundant data, difficult problem investigation and the like, and seriously influence the progress and quality of enterprise creation transformation. Therefore, a technical solution for efficiently and reliably migrating enterprise-level mail data to an created mailbox is needed. Disclosure of Invention In order to solve the above problems, the present invention provides a method for importing personal mail in a domestic mailbox system, comprising the following steps: The method comprises the steps of S1, reading user data and constructing a multithreading task to carry out parallel migration processing on user mails, S2, respectively carrying out identification processing on mail contents based on user mail types, S3, generating unique mail IDs corresponding to the processed mails, S4, carrying out migration importing on the mail data after identification and verification of the unique mail IDs, and S5, generating a comprehensive migration report after mail data migration is completed. Further, the user data in the step S1 specifically includes user login information, mail text, an address to be migrated, IMAP and a migration address. Further, the mail types of the user in the step S2 specifically comprise text type e-mails, image type e-mails and voice type e-mails. The step S2 specifically comprises the following substeps of S21 of obtaining relevant data of the user mail and classifying based on mail contents, S22 of identifying mail heads, mail texts and mail attachment contents and processing the mail attachments through UTF-8 coding, and S23 of detecting the integrity of the coded mail contents. Further, the step S3 specifically comprises the substeps of S31 judging whether a PST mail INTERMESSAGEID exists, if not, executing step S32, if so, directly using INTERMESSAGEID as a unique mail ID, S32 obtaining mail subject, sending time, sender and mail text part content through UTF-8 coding, S33 obtaining the number of recipients and the first two recipients, S34 obtaining mail size data, S35 adopting SHA-256 to replace MD5 and converting the obtained data into hexadecimal character strings, and S36 obtaining the first 16 bytes of hexadecimal character strings to generate the unique mail ID meeting RFC specifications. Further, the method also comprises a step of generating failure, wherein UUID is adopted as a unique mail ID when the hexadecimal character string is failed to be acquired. Further, the comprehensive migra
