Question

我想通过Guzzle从方法sendAsync返回响应，但是它返回空。

public function getliveflight_guzzle()
{
        $url = 'https://www.tesflight.com/ajax/pingFlightSearch?d=CGK&a=DPS&date=2018-08-18&adult=1&child=0&infant=0&service_class=&airlines=["MALAYSIAAIR"]&subsidy=true&page_view=roundseperate&refund_deposit=&refund_currency=';
        $client = new Client(['headers' => ['Accept' => 'application/json, text/javascript, */*; q=0.01', 'Accept-Language' => 'en-us,en;q=0.5', 'X-Requested-With' => 'XMLHttpRequest']]);

        // Send an asynchronous request.
        $request = new Psr7\Request('GET', $url, [
            'curl' => [
                CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17',
                CURLOPT_RETURNTRANSFER => TRUE,
                CURLOPT_SSL_VERIFYHOST => '0',
                CURLOPT_SSL_VERIFYPEER => '0',
                CURLOPT_AUTOREFERER => TRUE,
                CURLINFO_HEADER_OUT => true,
                CURLOPT_FOLLOWLOCATION => '1',
                CURLOPT_VERBOSE => true
            ]
        ]);
        $promise = $client->sendAsync($request)->then(function ($response) {
            return $response->getBody()->getContents();
        });
        $promise->wait();
}

public function actionTesguzzle()
{               
        $response = $this->getliveflight_guzzle();
        $response = json_decode($response, TRUE);
        print_r($response);
}

我也想尝试将$ response-> getBody（）-> getContents（）保存到变量中，然后尝试在sendAsync方法外回显它，但它显示为空。但是，如果我在sendAsync内部回显它，它将显示数据。怎么会这样？

请帮助。

您应该从函数return $promise->wait();返回值，请尝试以下操作：

public function getliveflight_guzzle()
{
        $url = 'https://www.tesflight.com/ajax/pingFlightSearch?d=CGK&a=DPS&date=2018-08-18&adult=1&child=0&infant=0&service_class=&airlines=["MALAYSIAAIR"]&subsidy=true&page_view=roundseperate&refund_deposit=&refund_currency=';
        $client = new Client(['headers' => ['Accept' => 'application/json, text/javascript, */*; q=0.01', 'Accept-Language' => 'en-us,en;q=0.5', 'X-Requested-With' => 'XMLHttpRequest']]);

        // Send an asynchronous request.
        $request = new Psr7\Request('GET', $url, [
            'curl' => [
                CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17',
                CURLOPT_RETURNTRANSFER => TRUE,
                CURLOPT_SSL_VERIFYHOST => '0',
                CURLOPT_SSL_VERIFYPEER => '0',
                CURLOPT_AUTOREFERER => TRUE,
                CURLINFO_HEADER_OUT => true,
                CURLOPT_FOLLOWLOCATION => '1',
                CURLOPT_VERBOSE => true
            ]
        ]);
        $promise = $client->sendAsync($request)->then(function ($response) {
            return $response->getBody()->getContents();
        });

        return $promise->wait();
}

public function actionTesguzzle()
{               
        $response = $this->getliveflight_guzzle();
        $response = json_decode($response, TRUE);
        print_r($response);
        echo json_last_error_msg();
}

您还可以使用函数json_last_error_msg()调试json的解码
