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。

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;

}

/**
 * Function:地址的处理
 * Author:cyw0413
 * @param $address
 * @return array
 * @throws \Exception
 */
function getAddressArrar($address){
 // 获取所有地址递归列表
 $regions = $this->getRegions();
 // 初始化数据
 $province = $city = $district = [];
 // 先查找省份-第一级地区
 $province = $this->checkAddress($address, $regions);
 if($province){

 $province_arr = ['110000','300000','404100','310000']; //4个 市辖区 如果地址不存在二级（市辖区，县），则特殊处理
 if(!isset($province['region_code'])){
 throw new \Exception("请正确填写省份(市辖区)");
 }
 // 查找城市-第二级地区
 $city = $this->checkAddress($address, $province['list']);
 //这里只处理4个市辖区，可能还有多种情况，待发现
 if(in_array($province['region_code'],$province_arr) && count($city['list']) == 0){
 $city = $this->checkAddress('市辖区', $province['list']);
 if($city){

前端html代码

<div class="form-group">
 {!! Form::label('discern', '自动识别地址:',['class' => 'control-label col-sm-2']) !!}
 <div class="col-sm-5">
 {!! Form::textarea('discern', '', ['class' => 'form-textarea form-control form-discern','rows' => 3]) !!}
 </div>
 <div class="col-sm-3" style="height: 75px;">
 <button type="button" class="btn btn-info btn-sm discern" onclick="getDiscern();" >提交识别</button>
 <small class="ruleGet" style="color: #676a74;">*查看模板</small>
 </div>

</div> 

jquery代码都有。。

/**
 * 地址识别
 * @returns {boolean}
 */
function getDiscern(){
 var discernDel = $(".form-discern").val();
 if(!discernDel){
 alert("请输入要识别的地址");
 return false;
 }

 $.ajax({
 type: 'POST',
 url: "{!! route('admin.user.getDiscern') !!}",
 data: {
 '_token': csrf_token(),
 'discernDel': discernDel
 },
 dataType: 'json',
 timeout: 50000,
 success: function (res) {
 if (res.code == 1) {
 $("input[name='addr[linkman]']").val(res.msg.name);
 $("input[name='user_name']").val(res.msg.mobile);
 $("input[name='addr[address]']").val(res.msg.info);

 //触发 change 事件
 $('#province').val(res.msg.province). trigger ('change');
 $('#city').val(res.msg.city).trigger('change');
 $('#area').val(res.msg.district).trigger('change');

 //识别后清除
 $(".form-discern").val("");

 } else {
 alert(res.msg);
 }
 }
 })

} 

代码可以帮你实现你想要的，不妨一试
