如何根据用户名 PHP 创建 URL

Question

这个问题可能看起来很模糊，我深表歉意，所以我会尽量在这里更好地解释它。基本上，我有 2 个 .php 文件，index.php 和 php.php。在 index.php 上，用户将他们的用户名输入到表单中，然后他们将在其中提交输入，php.php 然后获取用户名（使用 $_POST[] 方法。）并在该页面上显示数据.此时的 URL 看起来像这样；

http://minecraftnamespy.esy.es/php.php.

我该怎么做才能将用户输入的用户名添加到 URL？例如;

用户输入：_scrunch 作为用户名。

URL now changes from http://minecraftnamespy.esy.es/php.php to http://minecraftnamespy.esy.es/php?=_scrunch

我想指出，我在这里使用 Mojang API。我的 php.php 代码是：

<?php
  //error_reporting(E_ALL & ~E_NOTICE);
  // Load the username from somewhere
  if (
  $username = $_POST["username"]
  ) {
    //do nothing 
  } else {
    $username = "notch";
  }


  //allow the user to change the skin
  $skinChange = "<a href='https://minecraft.net/profile/skin/remote?url=http://skins.minecraft.net/MinecraftSkins/$username.png' target='_blank' </a>";

  //grabbing the users information
  if ($content = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . urlencode($username))
  ) {
    $userSkin = "<img src='https://mcapi.ca/skin/3d/$username' />";
  } else {
    $content = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . urlencode($username) . '?at=0');
  if( $http_response_header['0'] == "HTTP/1.1 204 No Content") {
      echo "Not a valid Minecraft Username! <a href='index.php'><button>Search Again?</button></a>";
      die;
  }
  $json = json_decode($content);

     foreach ($json as $currentName) {
     $currentName = $currentName;
  }

     $userSkin = "<img src='https://mcapi.ca/skin/3d/$currentName' />";
  }



  // Decode it
  $json = json_decode($content);

  // Check for error
  if (!empty($json->error)) {
      die('An error happened: ' . $json->errorMessage);
  }

  // Save the uuid
  $uuid = $json->id;

  // Get the history (using $json->uuid)
  $content = file_get_contents('https://api.mojang.com/user/profiles/' . urlencode($uuid) . '/names');

  // Decode it
  $json = json_decode($content);

  $names = array(); // Create a new array

  foreach ($json as $name) {
      $input = $name->name;

      if (!empty($name->changedToAt)) {
          // Convert to YYYY-MM-DD HH:MM:SS format
          $time = date('Y-m-d H:i:s', $name->changedToAt);

          $input .= ' (changed at ' . $time . ')';
      }

      $names[] = $input; // Add each "name" value to our array "names"

  }

  //url to users 2D head (avatar)
  $usersAvatar = "https://mcapi.ca/avatar/2d/$input/55";

  //user's Avatar as favivon
  $usersFavicon = "<link rel='shortcut icon' href='$usersAvatar' type='image/png' />";
  //use $uuid tp grab UUID of the user - ---- - - - use $names to get name history of the user.

这是用于在 index.php 上提交用户名的表单。

<form action="php.php" method="GET">
          <div class="form-group">
            <label for="username">Username:</label>
            <input type="text" class="form-control" id="username" name="username" placeholder="Enter username">
          </div>
          <button type="submit" class="btn btn-default">Submit</button>
</form>

Answer 1

你想要一个GET请求，在URL中以http://example.com/index.php?username=_scrunch

的形式可见

POST 请求是不可见的（即它不会出现在 URL 中）并且通常用于发送敏感数据（尽管 POST 是不足以保证数据安全！）。

将您的 POST 转换为 GET 是从

更改的简单问题

$username = $_POST["username"]

至

$username = $_GET["username"]

你可以使用这个，注意额外包含

if (!$_GET["username"]) {
    exit;
}

如果 username 不存在，这会导致您的页面退出加载并防止页面被滥用。

<?php
  //error_reporting(E_ALL & ~E_NOTICE);
  // Load the username from somewhere
  if (!$_GET["username"]) {
    exit;
  }
  if (
  $username = $_GET["username"]
  ) {
    //do nothing 
  } else {
    $username = "notch";
  }


  //allow the user to change the skin
  $skinChange = "<a href='https://minecraft.net/profile/skin/remote?url=http://skins.minecraft.net/MinecraftSkins/$username.png' target='_blank' </a>";

  //grabbing the users information
  if ($content = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . urlencode($username))
  ) {
    $userSkin = "<img src='https://mcapi.ca/skin/3d/$username' />";
  } else {
    $content = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . urlencode($username) . '?at=0');
  if( $http_response_header['0'] == "HTTP/1.1 204 No Content") {
      echo "Not a valid Minecraft Username! <a href='index.php'><button>Search Again?</button></a>";
      die;
  }
  $json = json_decode($content);

     foreach ($json as $currentName) {
     $currentName = $currentName;
  }

     $userSkin = "<img src='https://mcapi.ca/skin/3d/$currentName' />";
  }



  // Decode it
  $json = json_decode($content);

  // Check for error
  if (!empty($json->error)) {
      die('An error happened: ' . $json->errorMessage);
  }

  // Save the uuid
  $uuid = $json->id;

  // Get the history (using $json->uuid)
  $content = file_get_contents('https://api.mojang.com/user/profiles/' . urlencode($uuid) . '/names');

  // Decode it
  $json = json_decode($content);

  $names = array(); // Create a new array

  foreach ($json as $name) {
      $input = $name->name;

      if (!empty($name->changedToAt)) {
          // Convert to YYYY-MM-DD HH:MM:SS format
          $time = date('Y-m-d H:i:s', $name->changedToAt);

          $input .= ' (changed at ' . $time . ')';
      }

      $names[] = $input; // Add each "name" value to our array "names"

  }

  //url to users 2D head (avatar)
  $usersAvatar = "https://mcapi.ca/avatar/2d/$input/55";

  //user's Avatar as favivon
  $usersFavicon = "<link rel='shortcut icon' href='$usersAvatar' type='image/png' />";
  //use $uuid tp grab UUID of the user - ---- - - - use $names to get name history of the user.
