Generate project

micro gen command help:

NAME:
     micro gen - Generate a tp-micro project

USAGE:
     micro gen [command options] [arguments...]

OPTIONS:
     --template value, -t value    The template for code generation(relative/absolute)
     --app_path value, -p value  The path(relative/absolute) of the project

example: micro gen -p ./myapp or default micro gen myapp

The initial template file __tp-micro__tpl__.go:

// package __TPL__ is the project template
package __TPL__

// __API_CALL__ register CALL router:
//  /home
//  /math/divide
type __API_CALL__ interface {
    Home(*struct{}) *HomeResult
    Math
}

// __API_PUSH__ register PUSH router:
//  /stat
type __API_PUSH__ interface {
    Stat(*StatArg)
}

// __MYSQL_MODEL__ create mysql model
type __MYSQL_MODEL__ struct {
    User
    Log
    Device
}

// __MONGO_MODEL__ create mongodb model
type __MONGO_MODEL__ struct {
    Meta
}

// Math controller
type Math interface {
    // Divide handler
    Divide(*DivideArg) *DivideResult
}

// HomeResult home result
type HomeResult struct {
    Content string // text
}

type (
    // DivideArg divide api arg
    DivideArg struct {
        // dividend
        A float64
        // divisor
        B float64 `param:"<range: 0.01:100000>"`
    }
    // DivideResult divide api result
    DivideResult struct {
        // quotient
        C float64
    }
)

// StatArg stat handler arg
type StatArg struct {
    Ts int64 // timestamps
}

// User user info
type User struct {
    Id   int64  `key:"pri"`
    Name string `key:"uni"`
    Age  int32
}

type Log struct {
    Text string
}

type Device struct {
    UUID string `key:"pri"`
}

type Meta struct {

Desc:

This micro gen command only covers files with the ".gen.go" suffix if the __tp-micro__gen__.lock file exists
Add .gen suffix to the file name of the automatically generated file, DO NOT EDIT!
.tmp is temporary code used to ensure successful compilation!
It will be overwritten when micro gen is run!
When the project is completed, it should be removed!
The type of handler's parameter and result must be struct!
You can modify the created template file __tp-micro__tpl__.go, and run the micro gen command again to update the project

Param-Tags

tag	key	required	value	desc
param	query	no	name (e.g.`param:"<query>"` or `param:"<query:id>"`)	It indicates that the parameter is from the URI query part. e.g. `/a/b?x={query}`
param	swap	no	name (e.g.`param:"<swap:id>"`)	It indicates that the parameter is from the context swap.
param	desc	no	(e.g.`param:"<desc:id>"`)	Parameter Description
param	len	no	(e.g.`param:"<len:3:6>"`)	Length range [a,b] of parameter's value
param	range	no	(e.g.`param:"<range:0:10>"`)	Numerical range [a,b] of parameter's value
param	nonzero	no	-	Not allowed to zero
param	regexp	no	(e.g.`param:"<regexp:^\\w+$>"`)	Regular expression validation
param	rerr	no	(e.g.`param:"<rerr:100002:wrong password format>"`)	Custom error code and message

NOTES:

param:"-" means ignore
Encountered untagged exportable anonymous structure field, automatic recursive resolution
Parameter name is the name of the structure field converted to snake format
If the parameter is not from query or swap, it is the default from the body
Support for multiple rule combinations, e.g.param:"<regexp:^\\w+$><len:6:8><rerr:100002:wrong password format>"

Detail Example

Optimize

SetMessageSizeLimit sets max packet size. If maxSize<=0, set it to max uint32.

func SetMessageSizeLimit(maxMessageSize uint32)

SetSocketKeepAlive sets whether the operating system should send keepalive messages on the connection.

func SetSocketKeepAlive(keepalive bool)

SetSocketKeepAlivePeriod sets period between keep alives.

func SetSocketKeepAlivePeriod(d time.Duration)

SetSocketNoDelay controls whether the operating system should delay packet transmission in hopes of sending fewer packets (Nagle's algorithm). The default is true (no delay), meaning that data is sent as soon as possible after a Write.

func SetSocketNoDelay(_noDelay bool)

SetSocketReadBuffer sets the size of the operating system's receive buffer associated with the connection.

func SetSocketReadBuffer(bytes int)

SetSocketWriteBuffer sets the size of the operating system's transmit buffer associated with the connection.

func SetSocketWriteBuffer(bytes int)
