How do I bind form data to a model?
When binding form data to the model in web development, it is recommended to use the framework's own mechanism first, followed by manual binding and attention to field matching, structure nesting and data verification. Specific practices include: 1. Use built-in functions of the framework, such as ModelBinder of ASP.NETCore, @RequestBody of SpringBoot, ModelForm of Django, etc., to automatically complete type conversion and security verification; 2. Get request data in sequence, create model instances, and assign fields one by one (such as assigning req.body to User object in Express); 3. Ensure that the form field name is consistent with the model attributes, handle nested structures, and it is recommended to use DTO to isolate inputs.

Building Resilient Microservices with Polly and .NET
Using Polly is the key to building elastic .NET microservices. 1. Use the retry strategy to deal with transient failures and avoid increasing the service burden through exponential backoff; 2. Use the circuit breaker to prevent cascade failures, and fuse for 30 seconds after 3 consecutive failures; 3. Use the PolicyWrap combination strategy, the recommended order is circuit breaker, retry, and timeout to ensure that there is timeout control for each retry; 4. Automatically apply the policy through AddHttpClient combined with IHttpClientFactory in Program.cs; 5. Add a fallback strategy to return the default response when it fails, achieving elegant downgrade. Comprehensively use these strategies to build a highly available, fault-tolerant microservice system to ensure stable operation when dependent on service abnormalities
