执行php文件
func Test_exec(t *testing.T) { engine.Initialize() ctx := &engine.Context{ Output: os.Stdout, } err := engine.RequestStartup(ctx) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) err = ctx.Exec("/tmp/index.php") iferr != nil { fmt.Println(err) } }其中 /tmp/index.php 的内容为
Eval，返回值 func Test_eval(t *testing.T) { engine.Initialize() ctx := &engine.Context{} err := engine.RequestStartup(ctx) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) val, err := ctx.Eval("return "hello";") iferr != nil { fmt.Println(err) } defer engine.DestroyValue(val) ifengine.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) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) err = ctx.Bind("greeting","hello") iferr != nil { fmt.Println(err) } val, err := ctx.Eval("return $greeting;") iferr != nil { fmt.Println(err) } defer engine.DestroyValue(val) ifengine.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 { returnprovider.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) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) err = engine.Define("GreetingProvider", newGreetingProvider) iferr != nil { fmt.Println(err) } val, err := ctx.Eval(` $greetingProvider=newGreetingProvider("hello"); return$greetingProvider->GetGreeting();`) iferr != nil { fmt.Println(err) } defer engine.DestroyValue(val) ifengine.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) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) _, err = ctx.Eval("error_log("hello", 4); trigger_error("sent from golang", E_USER_ERROR);") iferr != 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) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) _, err = ctx.Eval("echo($_SERVER["REQUEST_URI"]);") iferr != nil { fmt.Println(err) } body, err := ioutil.ReadAll(recorder.Result().Body) iferr != nil { fmt.Println(err) } ifstring(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 $_ENVecho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_request ，用于在php里做一些异步完成的事情。这个特殊的全局函数必须支持
func Test_fastcgi_finish_reqeust(t *testing.T) { engine.Initialize() buffer := &bytes.Buffer{} ctx := &engine.Context{ Output: buffer, } err := engine.RequestStartup(ctx) iferr != nil { fmt.Println(err) } defer engine.RequestShutdown(ctx) ctx.Eval("ob_start(); echo ("hello");") ifbuffer.String() !=""{ t.FailNow() } ctx.Eval("fastcgi_finish_request();") ifbuffer.String() !="hello"{ t.FailNow() } }实际的作用就是把output提前输出到 ResposneWriter 里去，让调用方知道结果。对于当前进程的执行其实是没有影响的，只是影响了output。
