When generating the URL, the path parameter {xxx} is not replaced correctly, but instead xxx is added as a query parameter incorrectly

What happened:

生成URL时，没有正确替换路径参数{workspace_id}，而是错误地将workspaceId作为查询参数添加

What you expected to happen:

正确替换

How to reproduce it (as minimally and precisely as possible):

使用kratos v2.8.4

Anything else we need to know?:

Environment:

• Kratos version (use kratos -v): v2.8.4
• Go version (use go version): v1.20
• OS (e.g: cat /etc/os-release): wsl
• Others:

Hey there, @tangqiu0205! I'm here to help you with any bugs, questions, or contributions. Let's tackle this together while we wait for a human maintainer.

To correctly replace the path parameter {workspace_id} in the URL using Kratos v2.8.4 and Go v1.20, ensure that the EncodeURL function is used properly. Here's a concise example of how to achieve this:

package main

import (
	"fmt"
	"github.com/go-kratos/kratos/v2/transport/http/binding"
)

type MyMessage struct {
	WorkspaceID string `form:"workspace_id"`
}

func main() {
	pathTemplate := "/wayline/api/v1/workspaces/{workspace_id}/tasks"
	msg := &MyMessage{WorkspaceID: "your-uuid-value"}

	// Call EncodeURL with needQuery set to false to replace path parameters
	url := binding.EncodeURL(pathTemplate, msg, false)
	fmt.Println(url) // Output: /wayline/api/v1/workspaces/your-uuid-value/tasks
}

In this example, the MyMessage struct has a field WorkspaceID tagged with form:"workspace_id", which matches the path parameter {workspace_id} in the pathTemplate. The EncodeURL function will replace {workspace_id} with the value from msg.WorkspaceID, resulting in the correct URL without adding workspaceId as a query parameter ^[1].
