【问题描述】：
这个问题可能看起来很模糊，我深表歉意，所以我会在这里尝试更好地解释它。基本上，我有 2 个 .php 文件，index.php 和 php.php。在index.php 上，用户将在表单中输入他们的用户名，然后提交输入，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 如下所示；
http://minecraftnamespy.esy.es/php.php.
如何将用户键入的用户名添加到 URL 中？例如;
用户输入：_scrunch 作为用户名。
网址现在从
http://minecraftnamespy.esy.es/php.php更改为http://minecraftnamespy.esy.es/php?=_scrunch
我想指出，我在这里与Mojang API 合作。
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>
【问题讨论】：
-
你需要一个 GET 请求，而不是一个 POST 请求。
-
@ʎǝʞuoɯɹǝqʎɔ 我可以简单地将
$_POST["username"]更改为$_GET["username"]吗？ -
是的，但请记住我在下面的回答中概述的内容（在我提交后稍后会出现）。
