In the process of executing the instruction, parameters of a mailbox service protocol of a mailbox provider may change at any time, in order to ensure that the whole process of extracting the mail can be completed, a log reflecting the instruction execution condition can be recorded in the process of executing the instruction, the log is monitored, and when the log records error information of instruction execution, the instruction content is adjusted, so that the whole process of extracting the mail can be ensured to be completed.

Fig. 7 is a flowchart of another embodiment of the method for extracting mail with a proxy server as a main body. As shown in fig. 7, the present embodiment is different from the first embodiment of the method of extracting mail in that the method of extracting mail may further include:

s206: recording a log of the execution instruction of the proxy server, searching whether the log records information of instruction execution error or not in real time, and if the information of instruction execution error is recorded, correspondingly changing the instruction content executed by the proxy server according to the information of instruction execution error.

And recording instruction execution logs, wherein the instruction execution logs comprise a login instruction execution log, a mail search instruction execution log and a mail download instruction execution log which are generated in the process of executing the instructions in S202-S204. And searching whether the information of instruction execution errors is recorded in the log-in instruction execution log, the mail search instruction execution log and the mail download instruction execution log in real time. If the log records the information of instruction execution error, the currently executed instruction content is not matched with the service protocol parameters provided by the mailbox provider, and the data transmission between the proxy server and the mailbox server cannot be realized. And correspondingly changing the executed instruction content according to the instruction execution error information so as to ensure that the currently executed mail extraction process is continuously executed.

The log records information of instruction execution errors, and may include: the error code is recorded in the log. The error code may be generated when the executed instruction does not match a parameter of a service agreement provided by the mailbox provider.

Compared with the second embodiment of the method for extracting the mails, the method for extracting the mails has the advantages that the steps of recording the execution log and monitoring whether the execution log has instruction execution error information or not are added. The execution log includes: log instruction execution log, mail search instruction execution log, and mail download instruction execution log. And by recording the execution log, searching whether the execution log records the information of instruction execution errors in real time, and judging whether the currently executed instruction is matched with the parameters of the service protocol provided by the mailbox provider. If the currently executed instruction is not matched with the parameters in the service protocol provided by the mailbox provider, the content of the executed instruction is immediately changed, and the mail extraction process can be ensured to be continuously executed.

Fig. 8 is a configuration diagram of a second embodiment of the mail extraction system mainly including a proxy server according to the present application. As shown in fig. 8, the present embodiment is different from the first embodiment of the system for extracting mail in that the system for extracting mail further includes: an early warning unit 600.

The early warning unit 600 is configured to record a log of the instruction executed by the proxy server, search whether an instruction execution error message is recorded in the log in real time, and if an instruction execution error message is recorded, correspondingly change the instruction content executed by the proxy server according to the instruction execution error message.

Fig. 9 is a structural diagram of an early warning unit in a second embodiment of the system for extracting mails according to the present application. As shown in fig. 9, the early warning unit 600 includes: a log recording unit 610, an error information searching unit 620, an instruction content changing unit 630 and an instruction content returning unit 640. Wherein,

the log recording unit 610 is configured to record instruction execution logs generated by the mailbox logging unit 100, the mail searching unit 200, and the mail downloading unit 400. The instruction execution log may include: log instruction execution log, mail search instruction execution log, and mail download instruction execution log.

The error information searching unit 620 is configured to check the content of the instruction execution log recorded by the log recording unit 610 in real time, and determine whether an error occurs in the process of executing the instruction by the mailbox logging unit 100, the mail searching unit 200, and the mail downloading unit 400 according to the content of the instruction execution log. The occurrence of the error may be manifested as an error code recorded in the execution log, which may be generated when the content of the executed instruction does not match the parameters of the service protocol provided by the mailbox provider.

The instruction content changing unit 630 is configured to, when the instruction execution log recorded by the error information searching unit 620 finds the information of the instruction execution error, immediately change the content of the corresponding execution instruction according to the information of the instruction execution error, so as to ensure that the changed instruction content does not generate the information of the instruction execution error in the execution process.

The instruction content returning unit 640 is configured to return the instruction content modified by the instruction modifying unit 630 to the corresponding system unit. The respective system unit may include: a mailbox registration unit 100, a mail search unit 200, and a mail download unit 400.

The second embodiment of the mail extracting system with the proxy server as the main body corresponds to another embodiment of the mail extracting method with the proxy server as the main body, and an early warning unit is added on the basis of the first embodiment of the mail extracting system, and can record and monitor the instruction execution condition in the mail extracting process to ensure that the mail extracting process can be completed.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.

Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.
