如何在Laravel中传递数组作为URL参数？

---

要将数组作为URL参数传递，您可以使用PHP内置函数http_build_query()。http_build_query()函数返回一个URL编码的查询字符串。

示例1

使用http_build_query()

以下是此方法的示例：

$data = array(
   'field1' => 'test',
   'field2' => 'xyz'
);
echo http_build_query($data) . "
";

输出

以上代码的输出为：

field1=test&field2=xyz

以下示例演示了当您有一个数组需要作为URL参数传递时，如何使用http_build_query()。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".http_build_query($params);
   }
}

以上代码的输出为：

https://www.test.com?t1=abc&t2=xyz

示例2

您可以使用serialize()和urlencode PHP内置函数将数组作为URL参数传递。

serialize()函数将返回给定输入的位序列，而urlencode将再次对值以及其中可用的特殊字符进行编码。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      $firstserialize = serialize($params);
      echo $yourfinalurl = $yoururl."?".urlencode($firstserialize);
   }
}

输出

以上代码的输出为：

https://www.test.com?a%3A2%3A%7Bs%3A2%3A%22t1%22%3Bs%3A3%3A%22abc%22%3Bs%3A2%3A%22t2%22%3Bs%3A3%3A%22xyz%22%3B%7D

示例3

使用http_build_query()和urlencode()函数。

• urlencode() - 它将值编码为字符串。

• http_build_query() - 返回URL编码的查询字符串。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".urlencode(http_build_query($params));
   }
}

输出

以上代码的输出为：

https://www.test.com?t1%3Dabc%26t2%3Dxyz

示例4

使用urlencode()和jsonencode()

以下是一个使用jsconencode()和urlencode()函数将数组作为URL参数传递的示例：

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Http\Response;

class UserController extends Controller{
   public function index(Request $request) {
      $yoururl = "https://www.test.com";
      $params = array(
         "t1" => "abc",
         "t2" => "xyz"
      );
      echo $yourfinalurl = $yoururl."?".urlencode(json_encode($params));
   }
}

输出

以上代码的输出为：

https://www.test.com?%7B%22t1%22%3A%22abc%22%2C%22t2%22%3A%22xyz%22%7D
