字符串操作
截取字符串
<?php
use johnxu\tool\Str;
$res = Str::getInstance()->cut('http://www.johnxu.net', 0, 3);
var_dump($res); // htt
转换编码
<?php
use johnxu\tool\Str;
$res = Str::getInstance()->encoding('我们是好朋友', 'GBK');
var_dump($res); // �����Ǻ�����
var_dump(Str::getInstance()->encoding('�����Ǻ�����', 'UTF-8')); // 我们是好朋友
内置方法
- cut(string, start , length) 截取字符串
- lower(string) // 转换小写
- upper(string) // 转换大小
- has(string, neddle) // 查找是否存在该字符串
- remove(string, neddle) // 去除字符串
- reverse(string) // 翻转字符串
- arrayToString(array) // 将数组转换成字符串
- stringToArray(string) // 将字符串转换成数组
- ucwords(string) // 将字符串每个单子首字母大写
- ucfirst(string) // 将字符首字母大写
- generateTradeNo(length) // 创建订单号\
- generateUid(); // 创建用户ID
- getMachineCode(block, blockSize, split); // 创建机器激活码：8E8363C1-094E0EDC-7D67C393
- formatBytes(size, delimiter); // 格式化文件大小：10KB, 10MB
RSA生成签名串
<?php
use johnxu\tool\Rsa;
$data = '这是要签名的数据，字符串类型';
$private_key = ''; // 有两种方式，第一种是文件，写入文件路径即可；第二种是字符串，填写密钥字符串
$sign = Rsa::signature($data, $private_key); // 返回的签名后的base64字符串
RSA校验签名
<?php
use johnxu\tool\Rsa;
$sign = ''; // 签名串
$public_key = ''; // 同private_key
$data = '这是要签名的数据，字符串类型';
$result = Rsa::verify($data, $sign, $public_key); // 返回验签的结果
公私钥加密
<?php
use johnxu\tool\Rsa;
// 第三个参数有为，表示用公钥加密，私钥解密；反之
Rsa::encrypt('1234', 'private or public key', true);
公私钥解密
<?php
use johnxu\tool\Rsa;
// 第三个参数有为，表示用私钥解密；反之
Rsa::decrypt('加密数据', 'private or public key', true);
Config配置是用
<?php
$config = array(
'wx' => array(
'appid' => 1234,
'key' => 5678
),
'site_url' => 'http://www.johnxu.net'
);
// 批量设置
johnxu\tool\Config::batch($config);
// 单独设置
johnxu\tool\Config::set('wx', $config['wx']);
// 取值
johnxu\tool\Config::get('wx');
johnxu\tool\Config::get('wx.appid');
http请求的使用
<?php
use johnxu\tool\Http;
// get请求
$response = Http::getInstance()->request('http://www.baidu.com');
if ($response->getCode() == 200) {
var_dump($response->get('data'));// 原始数据
var_dump($response->getContent(false)); // 同上
var_dump($response->getContent()); // json解析后的数据（数组）
}
RESTFul风格的接口（只支持tp5）
<?php
namespace app\api\controller;
use johnxu\tool\Restful;
class Users extends Restful
{
// 模拟用户组
private $users
= array(
array(
'uid' => 1,
'authorization' => false,
'nickname' => 'tom',
'age' => 25,
'sex' => 'male',
'email' => 'tom@163.com'
),
array(
'uid' => 2,
'authorization' => false,
'nickname' => 'Alice',
'age' => 25,
'sex' => 'female',
'email' => 'Alice@163.com'
),
array(
'uid' => 3,
'authorization' => true,
'nickname' => 'peter',
'age' => 30,
'sex' => 'male',
'email' => 'peter@163.com'
),
);
// 获取所有的用户
public function index()
{
$this->ok( Restful::HTTP_RESPONSE_OK, $this->users );
}
// 获取指定用户的信息
public function get( $uid )
{
foreach ( $this->users as $user )
{
if ( $user['uid'] == $uid )
{
if ( $user['authorization'] == false )
{
// {"uid":2,"authorization":false,"nickname":"Alice","age":25,"sex":"female","email":"Alice@163.com"}
$this->ok( Restful::HTTP_RESPONSE_OK, $user );
}
else
{
// {"err_code":2001,"message":"UnAuthorization"}
$this->fail( Restful::HTTP_RESPONSE_UN_AUTHORIZATION, 2001, 'UnAuthorization' );
}
}
}
// {"err_code":1001,"message":"Not Found"}
$this->fail( Restful::HTTP_RESPONSE_NOT_FOUND, 1001, 'Not Found' );
}
}
```php
<?php
// 定义路由 route.php
Route::group( 'v1', function () {
Route::group( 'users', function () {
Route::get( '/', 'api/users/index' );, (*1)
Route::get( '/:uid', 'api/users/get' );
} );
} );, (*2)
// 访问：
// 获取所有用户：GET http://localhost/v1/useres
// 获取指定用户：GET http://localhost/v1/users/1, (*3)
