Because the request parameters include the signature information required by the PDF file, such as the signature type and the number, the required number of signing services is obtained according to the following scenarios:
scene 1: 1 PDF file needs to be subjected to 1 electronic signature; in this case, the scheduling requirement may include a request identifier 1, 1 electronic signature required may be included in the request parameter, and the number of the finally obtained signing services is 1, that is, 1 signing service performs signing operation of 1 electronic signature on the 1 PDF file;
scene 2: multiple PDF files need to be subjected to the same electronic signature; the scheduling requirement comprises a plurality of request identifications corresponding to each PDF file, the required same electronic signature information is included in the request parameters, and the finally obtained number of signing services is the same as the number of the plurality of PDF files, namely, the plurality of signing services simultaneously perform the signing operation of the same electronic signature on the plurality of PDF files respectively;
scene 3: 1 PDF file needs to be subjected to a plurality of electronic signatures; the scheduling requirement comprises a request identifier 1, the required multiple pieces of electronic signature information are included in the request parameters, the number of the electronic signatures is the final signing service number, namely, the multiple signing services respectively perform signing operation of each different electronic signature on the PDF file.
In the actual signing service scheduling process, if the scenes comprise the combination of the scenes, the number of the signing services is correspondingly accumulated to obtain the final required total number of the signing services.
Example 4
