尝试通过PHP Curl发送json时如何解决400错误请求？ Download

This is the API Chorus link to know exactly what I want to do.

卷曲类

class Curl
{
    protected $url;
    protected $header = array();
    protected $data;

    public function __construct( $url, $header, $data )
    {
        $this->url = $url;
        $this->header = $header;
        $this->data = $data;
    }

    public function sendPostJsonData( string $ssl_cert = null, string $ssl_certtype = null, $ssl_keypwd = null ){
        $json_data = json_encode( $this->data, JSON_FORCE_OBJECT );
        if( isJson( $json_data ) ){
            $this->header[] = sprintf( '%s: %s', "Content-Type", "application/json" );
            $this->header[] = sprintf( '%s: %s', "Content-Length", strlen( $json_data ) );

            $ch = curl_init( $this->url );
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST" );
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
            curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data );
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1 );
            curl_setopt($ch, CURLOPT_HTTPHEADER, $this->header );
            if( !empty( $ssl_cert ) ){
                $tempPemFile = tmpfile();
                fwrite( $tempPemFile, $ssl_cert );
                $tempPemPath = stream_get_meta_data( $tempPemFile );
                $tempPemPath = $tempPemPath['uri'];
                curl_setopt( $ch, CURLOPT_SSLCERT, $tempPemPath );
            }
            if( !empty( $ssl_certtype ) )
                curl_setopt( $ch, CURLOPT_SSLCERTTYPE, $ssl_certtype );
            if( !empty( $ssl_key ) )
                curl_setopt( $ch, CURLOPT_SSLKEYPASSWD, $ssl_keypwd );
            if( ! $result = curl_exec($ch) )
            {
                $result = curl_error($ch);
            }

            curl_close( $ch );
            return $result;
        }else{
            return false;
        }
    }
}

  

由于某种原因，我收到一个HTML响应，其中包含 400错误的请求。

我的问题是：

1. 使用PHP Curl发送json来获得这种错误的可能性有哪些
2. 如何获得更好的错误消息来解决我的问题？

如果您希望服务获得“漂亮”的响应，则可以检查第三方服务的响应代码。您可以使用try catch来防止错误并通过邮件返回受控的响应

在sendPostJsonData函数中检查响应状态

if (curl_getinfo($ch, CURLINFO_HTTP_CODE) != 200) {
    throw new Exception('Invalid response');
}

并在执行结束时发出不同的响应

try {
    ...
    $result = $curl->sendPostJsonData();
    ...
} catch (Exception $e) {
    echo json_encode(array(
        'status' => 'error',
        'msg' => 'your pretty response'
    ));
}
