基于 https://github.com/deuill/go-php 修改而来，fork缘由（https://github.com/deuill/go-php/issues/32）
执行php文件
func Test_exec(t *testing.T) {
engine.Initialize()
ctx := &engine.Context{
Output: os.Stdout,
}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
err = ctx.Exec("/tmp/index.php")
if err != nil {
fmt.Println(err)
}
}
其中 /tmp/index.php 的内容为
<?php
echo("hello\n");Eval，返回值
func Test_eval(t *testing.T) {
engine.Initialize()
ctx := &engine.Context{}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
val, err := ctx.Eval("return 'hello';")
if err != nil {
fmt.Println(err)
}
defer engine.DestroyValue(val)
if engine.ToString(val) != "hello" {
t.FailNow()
}
}返回的value的生命周期所有权是golang程序，所以我们要负责DestroyValue
设置全局变量来传参
func Test_argument(t *testing.T) {
engine.Initialize()
ctx := &engine.Context{}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
err = ctx.Bind("greeting", "hello")
if err != nil {
fmt.Println(err)
}
val, err := ctx.Eval("return $greeting;")
if err != nil {
fmt.Println(err)
}
defer engine.DestroyValue(val)
if engine.ToString(val) != "hello" {
t.FailNow()
}
}传递进去的参数的生命周期是php控制的，在request shutdown的时候内存会被释放。
PHP 回调 Golang
type greetingProvider struct {
greeting string
}
func (provider *greetingProvider) GetGreeting() string {
return provider.greeting
}
func newGreetingProvider(args []interface{}) interface{} {
return &greetingProvider{
greeting: args[0].(string),
}
}
func Test_callback(t *testing.T) {
engine.Initialize()
ctx := &engine.Context{}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
err = engine.Define("GreetingProvider", newGreetingProvider)
if err != nil {
fmt.Println(err)
}
val, err := ctx.Eval(`
$greetingProvider = new GreetingProvider('hello');
return $greetingProvider->GetGreeting();`)
if err != nil {
fmt.Println(err)
}
defer engine.DestroyValue(val)
if engine.ToString(val) != "hello" {
t.FailNow()
}
}
PHP 错误日志
func Test_log(t *testing.T) {
engine.PHP_INI_PATH_OVERRIDE = "/tmp/php.ini"
engine.Initialize()
ctx := &engine.Context{
Log: os.Stderr,
}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
_, err = ctx.Eval("error_log('hello', 4); trigger_error('sent from golang', E_USER_ERROR);")
if err != nil {
fmt.Println(err)
}
}
其中 /tmp/php.ini 的内容为
error_reporting = E_ALL error_log = "/tmp/php-error.log"
错误会被输出到 /tmp/php-error.log。直接调用error_log会同时再输出一份到stderr
HTTP 输入输出
func Test_http(t *testing.T) {
engine.Initialize()
recorder := httptest.NewRecorder()
ctx := &engine.Context{
Request: httptest.NewRequest("GET", "/hello", nil),
ResponseWriter: recorder,
}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
_, err = ctx.Eval("echo($_SERVER['REQUEST_URI']);")
if err != nil {
fmt.Println(err)
}
body, err := ioutil.ReadAll(recorder.Result().Body)
if err != nil {
fmt.Println(err)
}
if string(body) != "/hello" {
t.FailNow()
}
}
所有的PHP超级全局变量都会被初始化为传递进去的Request的值，包括
$_SERVER $_GET $_POST $_FILE $_COOKIE $_ENV
echo的内容，http code和http header会被写回到传入的ResponseWriter
fastcgi_finish_request
PHP-FPM 很常用的一个功能是fastcgi_finish_requesthttps://github.com/deuill/go-php를 기준으로 수정됨, 이유 포크용 (https://github.com/deuill/go-php/issues/32)
php 파일 실행
func Test_fastcgi_finish_reqeust(t *testing.T) {
engine.Initialize()
buffer := &bytes.Buffer{}
ctx := &engine.Context{
Output: buffer,
}
err := engine.RequestStartup(ctx)
if err != nil {
fmt.Println(err)
}
defer engine.RequestShutdown(ctx)
ctx.Eval("ob_start(); echo ('hello');")
if buffer.String() != "" {
t.FailNow()
}
ctx.Eval("fastcgi_finish_request();")
if buffer.String() != "hello" {
t.FailNow()
}
}
