# Get Chat Token

#### 一、userId、appId、appSecret值的获取

![developer](https://6941759-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FmV4PIbrO79lRJl9HCeLg%2Fuploads%2Fgit-blob-5222cec701ff2fcf91e149d41456bac8dd2a4ac0%2Fdeveloper.png?alt=media) 在直播管理后台，点击开发设置，在显示的页面中获取userId、appId、appSecret值。

#### 二、sign生成规则

将请求所需所有参数按照参数名字典顺序排列，连接参数名与参数值,并在首尾加上appSecret，然后计算MD5，将MD5结果转为16进制、大写字母，作为sign。

#### 三、Java sign生成示例 （详细请查看：[JAVA调用直播接口详述](https://git.polyv.net/help-center/document-center/-/blob/master/live/api/buildSign/README.md)）

```java
String appId = "XXXXXXXX";
String userId = "XXXXXXXX";
String appSecret = "XXXXXXXXXXXXXXXXXXXXXXXX";

long ts = System.currentTimeMillis();
// 创建参数表 （创建接口需要传递的所有参数表）
Map<String, String> paramMap = new HashMap<String, String>();
paramMap.put("appId", appId);
paramMap.put("timestamp", Long.toString(ts));

//对参数名进行字典排序
String[] keyArray = paramMap.keySet().toArray(new String[0]);
Arrays.sort(keyArray);

//拼接有序的参数串
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append(appSecret);
for (String key : keyArray) {
    stringBuilder.append(key).append(paramMap.get(key));
}

stringBuilder.append(appSecret);
String signSource = stringBuilder.toString();

String sign = org.apache.commons.codec.digest.DigestUtils.md5Hex(signSource).toUpperCase();
System.out.println("http://api.polyv.net/live/v1/users/" + userId + "/channels?appId=" + appId + "&timestamp=" + ts + "&sign=" + sign);

Copy
```

#### 四、PHP sign生成示例

**1、config.php文件代码**

```php
<?php
//签名验证必需参数
$appId = "XXXXXXXXX";
$timestamp = time()*1000;
$appSecret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

//获取sign函数
function getSign($params){
    global $appSecret;
    // 1. 对加密数组进行字典排序
    foreach ($params as $key=>$value){
     $arr[$key] = $key;
    }
    sort($arr);
    $str = $appSecret;
    foreach ($arr as $k => $v) {
     $str = $str.$arr[$k].$params[$v];
    }
    $restr = $str.$appSecret;
    $sign = strtoupper(md5($restr));
    return $sign;
}
?>
Copy
```

**2、接口请求示例**

```php
<?php

//引用config.php
include 'config.php';

//接口需要的参数（非sign）赋值
$userId = "XXXXXXXXX";

$params = array(
    'appId'=>$appId,
    'timestamp'=>$timestamp
  );

//生成sign
$sign = getSign($params); //详细查看config.php文件的getSign方法

//接口请求url
$url ="http://api.polyv.net/live/v1/users/".$userId."/channels?appId=".$appId."&timestamp=".$timestamp."&sign=".$sign;

//输出接口请求结果
$ch = curl_init() or die ( curl_error() );
curl_setopt( $ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, 360);
$response = curl_exec ( $ch );
curl_close ( $ch );
//打印获得的数据
print_r($response);

?>
```
