多商户2.3.0电子面单问题无法预览问题修复

1. 修改app/controller/admin/system/serve/Export.php中的 getExportTemp 方法，如下

public function getExportTemp(CrmebServeServices $services){    
    $com = $this->request->param('com');    
    if (!$com) return app('json')->fail('请输入快递公司编号');    
    $siid = merchantConfig($this->request->merId(),'mer_config_siid');    
    $func = $siid ? 'temp' : 'tempV2';    
    return app('json')->success($services->express()->{$func}($com));
}

通过商户siid判断是走新的电子面单方法还是旧的方法

2. 修改crmeb/services/express/storage/Express.php的 temp 方法，如下

public function temp(string $com)
{
    $param = ['com' => $com];
    return $this->accessToken->httpRequest(self::EXPRESS_TEMP, $param,'post',true);
}

去掉版本参数 ['version:v1.1']

3. crmeb/services/express/storage/Express.php中添加 tempV2 方法和 EXPRESS_TEMP_V2 常量，如下

const EXPRESS_TEMP_V2 = 'expr_dump/temp';


public function tempV2(string $com)
{
    $param = ['com' => $com];
    return $this->accessToken->httpRequest(self::EXPRESS_TEMP_V2, $param,'get',true, ['version:v1.1']);
}

新增一个常量和方法，没啥好说的

4. 修改crmeb/services/HttpService.php中的 request 方法，添加处理get请求参数逻辑，如下

public static function request($url, $method = 'get', $data = array(), $header = false, $timeout = 15)
{
    self::$status = null;
    self::$curlError = null;
    self::$headerStr = null;
    $method = strtoupper($method);
    if ($method == 'GET' && !empty($data)) $url .= "?". http_build_query($data);

    $curl = curl_init($url);
    //请求方式
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
    //post请求
    if ($method == 'POST') curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    //超时时间
    curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
    //设置header头
    if ($header !== false) curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
    curl_setopt($curl, CURLOPT_FAILONERROR, false);
    //返回抓取数据
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    //输出header头信息
    curl_setopt($curl, CURLOPT_HEADER, true);
    //TRUE 时追踪句柄的请求字符串，从 PHP 5.1.3 开始可用。这个很关键，就是允许你查看请求header
    curl_setopt($curl, CURLINFO_HEADER_OUT, true);
    //https请求
    if (1 == strpos("$" . $url, "https://")) {
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    }
    self::$curlError = curl_error($curl);
    list($content, $status) = [curl_exec($curl), curl_getinfo($curl), curl_close($curl)];
    self::$status = $status;
    self::$headerStr = trim(substr($content, 0, $status['header_size']));
    $content = trim(substr($content, $status['header_size']));
    return (intval($status["http_code"]) === 200) ? $content : false;
}

将 $method = strtoupper($method); 代码前移，添加get请求是处理参数的逻辑

5. 修改crmeb/services/express/storage/Express.php 中 express方法

return $this->accessToken->httpRequest(self::EXPRESS_LIST, $param,'get');
