[0047] The purpose, functional features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0049] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have a meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0050] The reconciliation process requires downloading suppliers' e-invoices. Each supplier's reconciliation files are hosted on servers with varying domain names. If each domain required a VPN to bypass security restrictions, the reconciliation process would be impossible. This is because the e-invoice download address is returned by the supplier's server via an API, and the returned content is merely a URL. However, the reconciliation logic needs to download the actual e-invoice image from this URL. If the code only bypasses the VPN after each "domain unreachable" exception, the process becomes extremely cumbersome and unsustainable.

[0051] Suppliers often use different platforms to store e-invoices, and the URLs provided by suppliers through their interfaces are uncontrollable. Furthermore, the domain names within each URL can vary widely, leading to uncontrollable business processes and hindering reconciliation operations. This often results in e-invoices being undownloadable, severely impacting the operation of the reconciliation logic. The sheer number and uncontrollable nature of the domains corresponding to e-invoice URLs, coupled with the need to bypass firewalls for every single domain encountered, leads to extremely low efficiency and significantly disrupts the normal operation of reconciliation.

[0052] In response to the problem in related technologies where electronic invoices cannot be downloaded due to the inability to access the supplier's server during reconciliation processing, which seriously affects the processing of reconciliation business, this application provides an electronic invoice acquisition method.

[0053] The electronic invoice acquisition method provided in this application embodiment can be applied to, for example, Figure 1 In this application environment, there are user clients, backend servers, proxy download servers, and multiple supplier servers. The backend server receives e-invoice download requests from the user client, extracts the first domain name, full address, and routing information from the request, selects a proxy download server based on the first domain name and full address, obtains the supplier proxy IP address from the proxy download server, and uses the proxy download server to send an access request carrying the first domain name and routing information to the supplier server based on the supplier proxy IP address. Upon receiving the access request, the supplier server obtains the e-invoice corresponding to the routing information and sends it to the proxy download server; it also receives the e-invoice forwarded by the proxy download server and forwards it to the user client. The user client can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The backend server, proxy download server, and supplier servers can all be implemented using independent servers or a server cluster consisting of multiple servers. The following detailed description of specific embodiments further illustrates this application.

[0054] like Figure 2 As shown, one embodiment of this application provides an electronic invoice acquisition method, applied to a backend server, including:

[0055] S10. Receive the electronic invoice download request sent by the user terminal.

[0056] The electronic invoice download request contains a URL for retrieving the electronic invoice. A URL, or Uniform Resource Locator, is a method used by the World Wide Web services on the Internet to specify the location of information.

[0057] S20. Extract the first domain name, full address, and routing information from the electronic invoice retrieval request.

[0058] In one implementation, extracting the first domain name, full address, and routing information from the electronic invoice retrieval request includes: extracting first URL information from the electronic invoice retrieval request; and extracting the first domain name, the full address, and the routing information from the first URL information.

[0059] For example, the first URL information could be http: / / www.financeforum.com / srch / item.rem?t=kl6. Here, the first URL information carries the first domain name financeforum.com and the routing information / srch / item.rem?t=kl6.

[0060] For example, the first URL information could be http: / / www.economy.com / srch / item.pub?s=qww1. Here, the first URL information carries the first domain name economy.com and the routing information / srch / item.pub?s=qww1.

[0061] For example, extracting the first domain name, the full address, and the routing information from the first URL information includes:

[0062] The first URL information is parsed by using a parallel processing method and calling a preset parsing rule to obtain the first domain name, the full address, and the routing information.

[0063] For example, the step of using a parallel processing method to parse the first URL information by invoking a preset parsing rule to obtain the first domain name, the full address, and the routing information includes:

[0064] For the first URL information, the Map / Reduce parallel method is used to traverse the trie corresponding to each preset parsing rule in turn until the parsing result corresponding to the first URL information is generated. The parsing result includes the first domain name, the full address and the routing information.

[0065] S30. Select a proxy download server based on the first domain name and the full address.

[0066] In a specific example, the backend system checks if a proxy download server IP address corresponding to the full address exists in its cache. If such an IP address exists, a proxy download server corresponding to that IP address is randomly selected to download the e-invoice. If no such IP address exists, the system checks if a proxy download server domain name exists in its cache. If so, a proxy download server domain name is randomly selected to download the e-invoice. If no domain name exists in the cache, the cache for domain names and full addresses is initialized, a mapping relationship is established between all proxy download server IP addresses and domain names / full addresses, and then a proxy download server IP address is randomly selected from the cache to download the e-invoice. During the e-invoice download process on the proxy download server, if a download error occurs (e.g., a "domain unreachable" error), the corresponding proxy download server IP address is removed from the domain name / full address mapping. One of the remaining proxy IP addresses in the domain name / full address mapping is selected to attempt a re-download. If, after multiple attempts, all proxy download server IP addresses fail to download the e-invoice, a message indicating that the download is unsuccessful is sent.

[0067] In some examples, the company owning the proxy download server can set up a fixed vendor proxy IP address on the internet, and the vendor server corresponding to that vendor proxy IP address provides proxy services to the proxy download server. Alternatively, the company can set up multiple proxy IP addresses on the internet, each corresponding to a proxy download server. By selecting a suitable proxy IP address from among these multiple addresses as the vendor proxy IP address, the vendor server corresponding to that vendor proxy IP address can provide faster and more efficient proxy services to the proxy download server.

[0068] S40. Obtain the supplier's proxy IP address based on the proxy download server.

[0069] In one implementation, obtaining the supplier proxy IP address based on the proxy download server includes: determining the attribute information of the proxy download server; and selecting a supplier proxy IP address that matches the attribute information from a plurality of preset supplier proxy IP addresses.

[0070] The attribute information of the proxy download server may include at least one of the following: geographical information and carrier information. For example, geographical information may be a provincial, municipal, or district-level classification; carrier information may include one of the various carriers. For instance, the attribute information of the proxy download server may be determined to include: geographical information as province A, and carrier information as carrier B.

[0071] The geographical information of multiple preset supplier proxy IP addresses can cover the whole country, and the operator information can include multiple operators. The proxy download server can select one supplier proxy IP address with geographical information of province A and operator information of operator B from multiple preset supplier proxy IP addresses as the supplier proxy IP address that matches the attribute information.

[0072] If no proxy IP address with region information of province A and operator information of operator B can be found, the proxy download server can select the proxy IP address with operator information of operator B and region information closest to province A as the supplier proxy IP address that matches the attribute information.

[0073] In another implementation, obtaining the supplier proxy IP address based on the proxy download server includes: obtaining a preset IP address from the proxy download server; accessing the target server corresponding to the preset IP address; and receiving the supplier proxy IP address pushed by the target server.

[0074] In this embodiment, to facilitate the integration and access of the proxy download server, a preset IP address, such as tlm specialcast ip, can be set within the proxy download server. All proxy download servers across the network can access the server corresponding to this preset IP address.

[0075] After accessing the server corresponding to a preset IP address, the proxy download server can receive the supplier proxy IP address pushed by the server corresponding to the preset IP address. Upon receiving the access from the proxy download server, the server corresponding to the preset IP address can first determine the attribute information of the proxy download server, then select the supplier proxy IP address that matches the attribute information from a pool of preset proxy IP addresses, and push the supplier proxy IP address to the proxy download server.

[0076] The process of determining the attribute information of the proxy download server by the server corresponding to the preset IP address, and identifying the supplier proxy IP address that matches the attribute information from multiple preset proxy IP addresses, can reduce the processing steps of the proxy download server and improve operating efficiency.

[0077] S50. Using the proxy download server, an access request carrying the first domain name and the routing information is sent to the supplier server according to the supplier proxy IP address, so that the supplier server can obtain the electronic invoice corresponding to the routing information after receiving the access request, and send the electronic invoice to the proxy download server.

[0078] In one implementation, sending an access request carrying the first domain name and the routing information to the supplier server based on the supplier proxy IP address includes:

[0079] The supplier proxy IP address is inserted after the protocol information of the first URL information and before the first domain name to obtain the second URL information;

[0080] Construct the access request corresponding to the second URL information;

[0081] The access request is sent to the supplier server that has the supplier's proxy IP address.

[0082] The destination IP address of the access request is the provider's proxy IP address, and the request content is the first domain name and routing information of the first URL.

[0083] In one example, the first URL information is http: / / mnpq / user?id=201, where the protocol information is http: / / ; the first domain name is mnpq; and the routing information is / user?id=201.

[0084] Assuming the supplier's proxy IP address is 3.7.5.6, inserting the supplier's proxy IP address after the protocol information and before the first domain name in the first URL information results in the second URL information as: http: / / 3.7.5.6 / mnpq / user?id=201.

[0085] After receiving an access request, the supplier server can determine the second domain name corresponding to the first domain name, determine the IP address corresponding to the second domain name based on the Domain Name System (DNS) server in the network, access the IP address, obtain the electronic invoice corresponding to the routing information, and send the electronic invoice back to the agent download server.

[0086] S60. Receive the electronic invoice forwarded by the proxy download server and forward the electronic invoice to the user terminal.

[0087] The proxy download server forwards the electronic invoice sent by the supplier server to the proxy download server, which then forwards the electronic invoice to the backend server, which in turn forwards it to the user.

[0088] The electronic invoice acquisition method provided in this application extracts a first domain name, full address, and routing information from the electronic invoice acquisition request. Based on the first domain name and the full address, a proxy download server is selected. Based on the proxy download server, the supplier proxy IP address is obtained. Using the proxy download server, an access request carrying the first domain name and the routing information is sent to the supplier server according to the supplier proxy IP address. This allows the supplier server to obtain the electronic invoice corresponding to the routing information after receiving the access request, and send the electronic invoice to the proxy download server. The supplier server also receives the electronic invoice forwarded by the proxy download server and forwards the electronic invoice to the user terminal. This method enables more accurate access to the supplier server where the electronic invoice is located, greatly improving the accuracy of electronic invoice download, the success rate of electronic invoice acquisition, and the processing efficiency of reconciliation business. It solves the technical problem in related technologies where the inability to access the supplier server normally during reconciliation business processing leads to the inability to download electronic invoices, which seriously affects the processing of reconciliation business.

[0095] The electronic invoice forwarding module is used to receive the electronic invoice forwarded by the agent download server and forward the electronic invoice to the user terminal.

[0100] The first URL information is parsed by using a parallel processing method and calling a preset parsing rule to obtain the first domain name, the full address, and the routing information.

[0101] In one implementation, the step of using a parallel processing method to parse the first URL information by invoking preset parsing rules to obtain the first domain name, the full address, and the routing information includes:

[0102] For the first URL information, the Map / Reduce parallel method is used to traverse the trie corresponding to each preset parsing rule in turn until the parsing result corresponding to the first URL information is generated. The parsing result includes the first domain name, the full address and the routing information.
