生成signature

签名规则说明

1. 将参数先按键值排序（只做一级排序），进行key和value的拼接

2. 拼接完后，在最后面再拼接上分配的 appSecret 然后用sha1对拼接串加密

签名示例

假如传入参数：

$param = array(

 'access_token' => '',

 'app_key' => '152968d9af768bf084dad750f78d6866',

 'once' => '911091697599',

 'version' => '1.0',

 'sdk_from' => 'java',

 'phone' => '13800138000',

 'type' => 0,

 'client' => '{"channel":"mcontact_md_ahlrj_api_android","imei":"1","version":"v3.9.8"}',

);

1.将参数先按键值排序（只做一级排序），即变成

$param = array(

 'access_token' => '',

 'app_key' => '152968d9af768bf084dad750f78d6866',

 'client' => '{"channel":"mcontact_md_ahlrj_api_android","imei":"1","version":"v3.9.8"}',

 'once' => '911091697599',

 'phone' => '13800138000',

 'sdk_from' => 'java',

 'type' => 0,

 'version' => '1.0',

);

2.然后拼接起来：

access_token=app_key=152968d9af768bf084dad750f78d6866client={"channel":"mcontact_md_ahlrj_api_android","imei":"1","version":"v3.9.8"}once=911091697599……

3. 拼接完后，在最后面再拼接上分配的 appSecret 然后用sha1对拼接串加密

示例代码，仅供参考：

签名生成方式

将需要提交的参数（signature除外）,按key做字典排序。 然后 key=value 形式拼接， 然后在后面 拼上 appscret。 再sha1加密

//具体php实现

function generateSignature($params_array, $appsecret) {

 if(!$appsecret){

 return '';

 }

 $str = '';

ksort($params_array, SORT_STRING);

 foreach ($params_array as $k=>$v) {

 $str .= $k."=".$v;

 }

 $str .= $appsecret;

 return sha1($str);

 }

 $signature = generateSignature($params_array, '分配的appscret'); //$params_array 就是需要提交的参数

//具体java实现

public String getNornmalSignature(HashMap<String, String> params, String appscret) {

 String signature = null;

 Map<String, String> sortedParams = new TreeMap<String, String>(params);

 Set<Entry<String, String>> entrys = sortedParams.entrySet();

 StringBuilder basestring = new StringBuilder();

 for (Entry<String, String> param : entrys) {

 basestring.append(param.getKey())

 .append("=")

 .append(param.getValue() == null ? "" : param.getValue());

 }

 basestring.append(appscret);

 try {

 signature = DigestUtils.shaHex(basestring.toString());

 } catch (Exception e) {

 e.printStackTrace();

 }

 return signature;

 }

 //java调用例子

 String once1 = new SimpleDateFormat("ssSSSS").format(new Date()) + String.valueOf(Math.random()).substring(2, 8);

 HashMap<String, String> hm1 = new HashMap<String, String>();

 hm1.put("app_key", app_key);

 hm1.put("once", once1);

 hm1.put("version", version);

 hm1.put("sdk_from", sdk_from);

 hm1.put("channel", channel);

 hm1.put("mobile", mobile);

 ……

 String signature1 = getNornmalSignature(hm1,appscret);
