How to Handle Route Conflicts Between Gin's Wildcard Route and Existing Child Routes?

Gin Wildcard Route Conflicts with Existing Children

The goal is to create a Gin application that serves different resources for specific routes, while a default resource is served for all other routes. However, when defining a wildcard route (), a conflict arises with existing child routes ().

To overcome this dilemma, one can utilize the gin.NoRoute(...) function. This function allows you to handle routes that weren't explicitly defined. Here's how the code would look like:

<code class="go">r.GET("/special", func(c *gin.Context) {
    // Serve the special resource...
})

r.NoRoute(func(c *gin.Context) {
    // Serve the default resource...
})</code>
Copy after login

By using NoRoute, Gin will only serve the default resource when no other specific routes match the request URI. This approach ensures that specific routes take precedence over the wildcard route.

Golang's Purpose: Building Efficient and Scalable Systems Golang's Purpose: Building Efficient and Scalable Systems Apr 09, 2025 pm 05:17 PM

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.

Golang vs. Python: Performance and Scalability Golang vs. Python: Performance and Scalability Apr 19, 2025 am 12:18 AM

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Golang and C  : Concurrency vs. Raw Speed Golang and C : Concurrency vs. Raw Speed Apr 21, 2025 am 12:16 AM

Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.

Golang vs. Python: Key Differences and Similarities Golang vs. Python: Key Differences and Similarities Apr 17, 2025 am 12:15 AM

Golang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.

Golang vs. C  : Performance and Speed Comparison Golang vs. C : Performance and Speed Comparison Apr 21, 2025 am 12:13 AM

Golang is suitable for rapid development and concurrent scenarios, and C is suitable for scenarios where extreme performance and low-level control are required. 1) Golang improves performance through garbage collection and concurrency mechanisms, and is suitable for high-concurrency Web service development. 2) C achieves the ultimate performance through manual memory management and compiler optimization, and is suitable for embedded system development.

Golang and C  : The Trade-offs in Performance Golang and C : The Trade-offs in Performance Apr 17, 2025 am 12:18 AM

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.

C   and Golang: When Performance is Crucial C and Golang: When Performance is Crucial Apr 13, 2025 am 12:11 AM

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.
