Abstract
Provided are a long-distance function call transmission adapter and a data reading method thereof. The method comprises the steps of reading original payload input by a systems, applications and products in data processing (SAP) system to a request for comments (RFC) transmission adapter; analyzing the read original payload to obtain a file transfer protocol (FTP) route of the data and a text file name of the data, connecting the FTP route and the text file name obtained by analysis to a FTP server and reading a text file in the FTP server; converting the read text file into the file in extensive makeup language (XML) format; and regarding the converted file in the XML format and the content of the original payload as new payload to replace the original payload and providing the new payload to a process intelligence (PI) server. By means of the long-distance function call transmission adapter and the data reading method of the long-distance function call transmission adapter, the transmission adapter can dynamically read the text file.
Description
Technical field
The present invention relates to the method for a kind of remote function calls transmission adapter and reading of data thereof.
Background technology
At present; Enterprises all has application system separately; For example, factory's finished product management system, former material management system, purchasing system, bonded storehouse system etc. are in the time of in each application system that the data in the SAP is sent to enterprises; Be that this flow process is a RFC Outbound flow process with in identical data transmission to a plurality of application systems or the application system group.RFC (remote function call remote function calls) is the interface protocol of a SAP, has simplified the programing work of communication between system to a great extent, allows to call and carry out a remote system, or the pre-defined function on the identical systems.Wherein, in this RFC Outbound flow process, require when carrying out RFC; Dynamically the position at typing data place refers to FTP (file transfer protocol, FTP) path here; Carry out RFC then, this RFC reads data automatically according to the position of data and sends to flow process and integrates (PI, process integration) server; Also be about to this FTP path and input among the standard RFC Sender Adapter (RFC transmission adapter) in the PI server, but this standard RFC adapter in the PI server can only receive the parameter (comprising input and table) of RFC input, is translated into XML (extensible markup language as parameter; Extend markup language) file but can not (be actually the FTP address, port through the parameter of this input; User name; Password, file name etc.), come to read dynamically ftp file.
Summary of the invention
In view of above content, be necessary to provide the method for a kind of remote function calls transmission adapter and reading of data thereof, let the remote function calls transmission adapter can read ftp file dynamically.
A kind of remote function calls transmission adapter; Be arranged in flow process and integrate the PI server; This PI server is connected with SAP system and goal systems communication respectively, and the data that described SAP system will send goal systems to leave on the ftp server with text file format.This far call transmission adapter comprises: read module; Be used to read the original payload payload that the SAP system inputs to the remote function calls transmission adapter; The content of said original payload is made up of the parameter of the data that will be sent to goal systems, and this parameter comprises FTP address, port, user name, password and the file name of store data; Parsing module is used to resolve the original payload that is read, with the FTP path and the text title of the data that obtain being sent to goal systems; Calling module, the FTP path that is used to utilize parsing to obtain is connected to ftp server, and reads the text in the ftp server according to the text title that parsing obtains; Said calling module also is used for the text that is read is converted into the file of expandable mark language XML form; Processing module is used for parameter with the file of the XML form after transforming and input remote function calls transmission adapter as new payload, replaces original payload, to offer the PI server.
A kind of method of remote function calls transmission adapter reading of data; Being applied to flow process integrates in the PI server; This PI server is connected with SAP system and goal systems communication respectively, and the data that described SAP system will send goal systems to leave on the ftp server with text TXT form.The method comprising the steps of: a. reads the original payload payload that the SAP system inputs to the remote function calls transmission adapter; The content of said original payload is made up of the parameter of the data that will be sent to goal systems, and this parameter comprises FTP address, port, user name, password and the file name of store data; B. resolve the original payload read, with the FTP path and the text title of the data that obtain being sent to goal systems; C. the FTP path that utilizes parsing to obtain is connected to ftp server; D. the text title that obtains according to parsing reads the text in the ftp server; E. the text that is read is converted into the file of expandable mark language XML form; The parameter of the file of the XML form after f. will transforming and input remote function calls transmission adapter is replaced original payload, to offer the PI server as new payload.
Compared to prior art, the method for said remote function calls transmission adapter and reading of data thereof lets the remote function calls transmission adapter (be actually the FTP address through the parameter of input; Port; User name, password, file name etc.); Read the text on the ftp server, strengthened the function of transmission adapter.
