public function make($abstract, $vars = [], $newInstance = false)
{
if (true === $vars) {
// 总是创建新的实例化对象
$newInstance = true;
$vars = [];
}
$abstract = isset($this->name[$abstract]) ? $this->name[$abstract] : $abstract;
if (isset($this->instances[$abstract]) && !$newInstance) {
return $this->instances[$abstract];
}
if (isset($this->bind[$abstract])) {
$concrete = $this->bind[$abstract];
if ($concrete instanceof Closure) {
$object = $this->invokeFunction($concrete, $vars);
} else {
$this->name[$abstract] = $concrete;
return $this->make($concrete, $vars, $newInstance);
}
} else {
$object = $this->invokeClass($abstract, $vars);
}
if (!$newInstance) {
$this->instances[$abstract] = $object;
}
return $object;
}我把源代码的删除 $abstract = isset($this->name[$abstract]) ? $this->name[$abstract] : $abstract;
$this->name[$abstract] = $concrete;得到下面的代码，且运行正常 public function make($abstract, $vars = [], $newInstance = false)
{
if (true === $vars) {
// 总是创建新的实例化对象
$newInstance = true;
$vars = [];
}
if (isset($this->instances[$abstract]) && !$newInstance) {
return $this->instances[$abstract];
}
if (isset($this->bind[$abstract])) {
$concrete = $this->bind[$abstract];
if ($concrete instanceof Closure) {
$object = $this->invokeFunction($concrete, $vars);
} else {
return $this->make($concrete, $vars, $newInstance);
}
} else {
$object = $this->invokeClass($abstract, $vars);
}
if (!$newInstance) {
$this->instances[$abstract] = $object;
}
return $object;
}请问 $this->name 这个属性到底有什么用呀？ 最佳答案
