[0025] The evidence chain node information query method provided in the present application can be applied to a computer device (electronic device), which can be a server or a terminal, wherein the server can be a single server or a server cluster composed of multiple servers. The embodiments of the present application do not specifically limit this. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices.

[0026] Take the computer device as a server as an example. Figure 1 A block diagram of a server is shown, such as Figure 1 As shown, the server may include a processor and a memory connected via a system bus. The processor of the server is used to provide computing and control capabilities. The memory of the server includes a non-volatile storage medium and an internal memory.

[0027] Those skilled in the art will understand that Figure 1 The structure shown in the figure is only a block diagram of a partial structure related to the solution of the present application, and does not constitute a limitation on the server to which the solution of the present application is applied. Optionally, the server may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0028] It should be noted that the execution subject of the embodiments of the present application can be a computer device or an evidence chain node information query device. The following method embodiments will be described using a computer device as the execution subject.

[0029] Figure 2 A flowchart of a method for querying node data in an evidence chain provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps: Step 202: Obtain the associated node information and associated field information of the target evidence chain node.

[0030] The associated node information is used to represent the data type corresponding to the target evidence chain node, and the associated field information is used to represent the node name corresponding to the target evidence chain node. The associated node information and associated field information can be displayed in the node details. For example, Figure 3 As shown, Figure 3 A schematic diagram of node details provided for an embodiment of the present application, in which the data type in the node details may be Contract 2, and the node name may be Prepayment Application Form_Purchase Prepayment.

[0031] Optionally, the user can manually add the associated node information and associated field information on the evidence chain configuration page. Optionally, the associated node information and associated field information can also be arbitrarily associated and combined, which is not specifically limited in the embodiments of the present application.

[0032] Step 204: query the target evidence chain node data corresponding to the associated node information and the associated field information through the preset query rules.

[0033] In some optional embodiments, the preset query rules may include node query restriction conditions corresponding to the target evidence chain node, such as Figure 4 As shown, Figure 4 A flowchart of the steps for querying target evidence chain node data provided in an embodiment of the present application includes: Step 402: Obtain the node query restriction condition corresponding to the target evidence chain node input by the user.

[0034] Step 404: Based on the node query restriction condition, query the target evidence chain node data corresponding to the associated node information and the associated field information.

[0035] The node query restriction condition is used to determine the current search scope. For example, please continue to refer to Figure 3 , the node query restriction condition is also the node query restriction dimension, which can include contract number, document number 2, etc., or other specific fields, such as add, major category primary key 1112, Huilianyi, text array, etc.

[0036] Optionally, the node query restriction condition can be selected by the user in a pre-configured selection box, in which a variety of node query restriction conditions are pre-configured. Thus, based on the node query restriction condition, the target evidence chain node information corresponding to the associated node information and the associated field information can be queried and obtained.

[0037] In this embodiment, by adding corresponding node query restriction conditions, it is convenient for the viewer to restrict the query results, thereby facilitating the query and narrowing the current search scope.

[0038] In some optional embodiments, the node query restriction condition may be a pre-configured fixed query condition, such as Figure 5 As shown, Figure 5 Another step flow chart for querying target evidence chain node information provided in an embodiment of the present application includes: Step 502: Obtain the fixed query condition selected by the user in the preset configuration query scheme.

[0039] Step 504: Based on the fixed query conditions, query the target evidence chain node information corresponding to the associated node information and the associated field information.

[0040] The evidence chain configuration page also supports adding default query conditions, which are fixed query conditions selected in the preset configuration query scheme. For example, a configuration query scheme button can be set on the evidence chain configuration page, and the user can display the specific content corresponding to the configuration query scheme button on the evidence chain configuration page by clicking the button.

[0041] like Figure 6 As shown, Figure 6 A schematic diagram of fixed query conditions in a preset configuration query scheme provided in an embodiment of the present application. After the user clicks the configure query scheme button, the specific content displayed may include scheme 1 field, set as default button, delete button, node selection box, query condition selection box, remarks box, add query scheme button and other contents.

[0042] In this embodiment, by setting a configuration query scheme button on the evidence chain configuration page, the user can select a fixed query condition in the preset configuration query scheme, and then query the target evidence chain node information corresponding to the associated node information and associated field information based on the fixed query condition. This can facilitate users who are not familiar with the use of evidence chain queries, and they can make choices based on the fixed query conditions selected in the preset configuration query scheme, thereby reducing learning costs.

[0043] In some optional embodiments, the preset query rules may include a preset mapping table, and the target evidence chain node data corresponding to the associated node information and the associated field information are queried through the preset query rules, including: querying the target evidence chain node data corresponding to the associated node information and the associated field information through the preset mapping table.

[0044] The evidence chain configuration page also supports setting field mapping relationships. Node association is not limited to direct association, and association queries can be performed through preset mapping tables. In other words, you can set mapping relationships for multiple associated fields, so that you can query the target evidence chain node information corresponding to the associated node information and associated field information through the preset mapping table, thereby reducing the dependence on the transformation of the front-end business system during the collection stage.

[0045] In some optional embodiments, the target evidence chain node is any node on the target evidence chain, and the target evidence chain node data is the node data corresponding to all nodes on the target evidence chain. Among them, on the evidence chain query page, according to the selected configured target evidence chain, any node on the target evidence chain can be used as a query condition to find out all corresponding node data on the entire target evidence chain.

[0046] In some optional embodiments, a data attachment preview button, a data detail export button, and a download button can also be set on the evidence chain query page. The results of the evidence chain query can also be packaged and stored for easy access in historical queries. All historical data supports viewing detailed details, and the detail list or attachment can be downloaded or loaned out for easy access by users in need.

[0047] Optionally, the result of the evidence chain query can be stored in a preset database, so that after obtaining the user's first access request, the target evidence chain node information can be obtained from the preset database based on the first access request. The first access request is a request initiated by the user to view the target evidence chain node information, and the preset database pre-stores a plurality of target evidence chain node information, and the target evidence chain node information in the preset database is historical data.

[0048] In some optional embodiments, the evidence chain details page also supports recording audit opinion information, and the audit opinion information can be filled in or an attachment can be uploaded, so that the audit can be viewed at any time for subsequent review. Therefore, after obtaining the user's second review request, the audit opinion information corresponding to the target evidence chain node information can be obtained based on the second review request and displayed on the preset evidence chain details page. Among them, the second review request is a request initiated by the user to view the audit opinion information.

[0049] Step 206: Display the target evidence chain node information on a preset display interface.

[0050] After the target evidence chain node data is queried, it can also be displayed on a preset display interface. Optionally, the specific format of the display can be in a list form or in a graphical form, which is not specifically limited in the embodiment of the present application.

[0051] The present application provides a method for querying information on a node in an evidence chain, the method comprising: obtaining associated node information and associated field information of a target evidence chain node, wherein the associated node information is used to characterize the data type corresponding to the target evidence chain node, and the associated field information is used to characterize the node name corresponding to the target evidence chain node, querying the target evidence chain node information corresponding to the associated node information and the associated field information through preset query rules, and displaying the target evidence chain node information on a preset display interface. This solution sets an evidence chain configuration page and an evidence chain query page, so that the corresponding target evidence chain node information can be quickly queried based on the configured associated node information and associated field information, and then through preset query rules, thereby improving the efficiency of querying node information on the entire evidence chain; in addition, by displaying the target evidence chain node information on a preset display interface, the convenience of users viewing the target evidence chain node information is improved.
