What the data for this category looks like
The daily documents included in this category include construction permit applications, qualified construction drawing review certificates, quality and safety supervision procedures, completion acceptance record forms, and more. Data sources include the engineering construction project approval management system, construction drawing review system, enterprise qualification database, and credit platform, with an update frequency of once per day. The data covers the approval process of engineering construction projects from project initiation to acceptance, and includes core content such as project identifiers, participating entity information, and approval node status. The field structure of different documents varies based on the approval stage.
Constraints on HTTP Interfaces and External Systems
The need to integrate multiple data sources requires interfaces to support connections with multiple external systems and adapt to different interface specifications. Daily updated data requires configuring scheduled pull or synchronization mechanisms to ensure data timeliness. Diverse document structures require interfaces to support different field extraction rules to accurately retrieve required document content. Strict approval process requirements mean interface calls must align with approval process nodes, and fault tolerance mechanisms must be included to prevent approval delays caused by interface exceptions.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer {interface key issued by external system} | Meets identity verification requirements of external systems such as the engineering construction project approval management system |
variables | Bind business fields including project numbers, participating unit qualifications, approval node status, and more | Adapt to document template filling needs for different approval stages |
responseData | Extract target fields including document main text, approval status, associated qualification information, and more | Accurately obtain core data used for document and material drafting |
| Interface timeout period | 600 seconds | Accommodate potential long response delays from engineering approval system interfaces |
| Data pull frequency | 1 time every 24 hours | Matches the daily update business rhythm of data in this category |
| Retry attempts | 3 times | Address scenarios of temporary network fluctuations or short-term interface exceptions |
Three Common Configuration Mistakes
- An error "message receiving address verification failed" is prompted when calling an external interface. The cause is that no publicly accessible interface address is configured, or SSL certificate verification requirements are not handled correctly.
Reference only; verify against the target FastGPT release and deployment documentation.
- The target data returned by the interface is empty. The cause is that the specified fields in
responseDataare not extracted correctly, or the request parameters do not match the interface requirements of the external system.
How to Confirm the Configuration Is Complete
- Initiate a single test request, and verify whether the returned
responseDataincludes preset business fields. - Check whether the format of the
Authorizationparameter complies with the identity verification rules of the external system, and confirm that identity verification is passed. - Trigger a manual data pull task, and verify that the process runs normally and data synchronization is completed.
- Simulate an approval node change, and confirm that the parameters bound to
variablescan be correctly embedded into the document template.
