PHP自动(智能)识别地址到表单

地址自动识别现在普遍,特别是用在快递填写地址,姓名,手机号码的时候,会把这些按照一定的规范填写后,点击自动识别后,会自动填写到各自的input。最近也简单的实现了这个功能,给后台添加用户的时候,自动识别地址。下面咱们来看看具体实现。

效果图

代码实现

controller,这里首先注入服务容器,在构造函数里注入。

/** @var  UserRepository */
private $userRepository;
public function __construct(UsersRepository $userRepo)
{
    $this->userRepository = $userRepo;
}
/**
 * Function:地址识别
 * Author:cyw0413
 * @param Request $request
 * @return \Illuminate\Contracts\Routing\ResponseFactory|\Illuminate\Http\Response|
 * \Laravel\Lumen\Http\ResponseFactory|\Symfony\Component\HttpFoundation\Response
 */
public function getDiscern(Request $request)
{
    $discernDel = $request->input('discernDel');
    try{
       DB::beginTransaction();
       $address = $this->userRepository->getDiscern($discernDel);
       DB::commit();

    }catch (\Exception $e){
        DB::rollBack();
        $msg = "信息提示:".$e->getMessage().",行:".$e->getLine();
        return response(['code' => 0, 'msg'=>$msg]);
    }

    return response(['code'=>1,'msg'=>$address]);   //地址识别完成

}

userRepository容器,用来处理地址识别的各种业务代码

/**
 * Function:识别地址
 * Author:cyw0413
 */
public function getDiscern($discernDel)
{
    if (empty($discernDel)) {
        throw new  \Exception("请传入要识别的地址");
    }

    $discernDel_left = explode ('[', $discernDel);
    if (!isset($discernDel_left[1])) {
        throw new  \Exception("你填写的地址规则错误,手机号码应该用[]");
    }
    $discernDel_right = explode (']', $discernDel_left[1]);
    if (!isset($discernDel_right[1]) || empty($discernDel_right[1])) {
        throw new  \Exception("你填写的地址规则错误,手机号码应该用[]");
    }

    $name = $discernDel_left[0];
    if (empty($name)) {
        throw new  \Exception("你填写的姓名有误!");
    }
    $mobile = $discernDel_right[0];
    if (empty($mobile) || checkMobile($mobile) == 0) {
        throw new  \Exception("你填写的手机号码格式有误!");
    }
    $address = trim ($discernDel_right[1]);
    if (empty($address)) {
        throw new  \Exception("你填写的地址不能为空");
    }

    $var_address = $this->getAddressArrar($address);
    $var_address['name'] = $name;
    $var_address['mobile'] = $mobile;

    return $var_address;

}

jquery代码
