小程序接入客服消息

1、消息推送配置

小程序

填写URL、Token等。

特别要注意的是：数据格式的选择；

为了后续其他信息能够转发回微信自有网页版客服消息平台，建议选择xml格式。
json格式现在还有bug(2018.3.5)，

bug主要原因返回的头部不符合http标准。
返回json格式header头应该是

Content-Type:application/json,

而微信的选json还是

Content-Type:text/xml，

2、代码如下，直接改改就能用(这里用的php)

?php define("TOKEN","你小程序自己设置的Token");//填写自己设置的Tokenclass wechatAPI{    const APP_ID = '你自己的appid';    const APP_SECRET = '你自己的appsecret';        //用于小程序第一步验证返回    public function isValid(){        $echoStr = $_GET["echostr"];        if ($this-checkSignature()) {            echo $echoStr;            exit;        }    }        public function checkSignature(){        $signature = $_GET["signature"];        $timestamp = $_GET["timestamp"];        $nonce = $_GET["nonce"];        $token = TOKEN;        $tmpArr = array($token, $timestamp, $nonce);        sort($tmpArr, SORT_STRING);        $tmpStr = implode( $tmpArr );        $tmpStr = sha1( $tmpStr );        if( $tmpStr == $signature ){            return true;        }else{            return false;        }    }            public function send($data){        $url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$this-getAccessToken();        $data = urldecode(json_encode($data));        $this-curl_post($url,$data);    }        //xml数据转数组    public function xml2Array($contents = NULL, $encoding = 'UTF-8', $get_attributes = 1, $priority = 'tag'){        if (!$contents)         {            return array();        }        if (!function_exists('xml_parser_create'))        {            return array ();        }        $parser = xml_parser_create('');        xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, $encoding);        xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);        xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);        xml_parse_into_struct($parser, trim($contents), $xml_values);        xml_parser_free($parser);        if (!$xml_values)            return array();         $xml_array = array ();        $parents = array ();        $opened_tags = array ();        $arr = array ();        $current = & $xml_array;        $repeated_tag_index = array ();         foreach ($xml_values as $data)        {            unset ($attributes, $value);            extract($data);            $result = array ();            $attributes_data = array ();            if (isset ($value))            {                if ($priority == 'tag')                    $result = trim($value);                else                    $result['value'] = trim($value);            }            if (isset ($attributes) && $get_attributes) {                foreach ($attributes as $attr = $val)                {                    if ($priority == 'tag')                        $attributes_data[$attr] = $val;                    else                        $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr'                }            }            if ($type == "open")            {                 $parent[$level -1] = & $current;                if (!is_array($current) || (!in_array($tag, array_keys($current)))) {                    $current[$tag] = $result;                    if ($attributes_data)                        $current[$tag .
