cURL错误6：无法解析主机-Guzzle

Question

Description

guzzle version 6.3

If I have this in my class

class CURL {

public static function get($url) {

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_TIMEOUT_MS, 1000);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); //<------ Note HERE 
    curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
    $result = curl_exec($ch);
    curl_close($ch);
    $result =  json_decode($result, true);
    return $result;

}

If I have this in my class

Try #1

<?php
namespace App;

use Request,Auth;
use App\Log, App\Helper;

use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Client;

use GuzzleHttp\FORCE_IP_RESOLVE;
use GuzzleHttp\DECODE_CONTENT;
use GuzzleHttp\CONNECT_TIMEOUT;
use GuzzleHttp\READ_TIMEOUT;
use GuzzleHttp\TIMEOUT;

use GuzzleHttp\VERIFY;



class CURL {

    $client = new Client();
    $options = [
        'http_errors' => false,
        'force_ip_resolve' => 'v4',
        'connect_timeout' => 10,
        'read_timeout' => 10,
        'timeout' => 10,
        'verify' => false
    ];
    $result = $client->request('GET',$url,$options);
    $result = json_decode((string) $result->getBody(), true);
    return $result;
    ...

}

As you can see, I tried set 'verify' => false already.

I got

Try #2

add 'curl' => [ CURLOPT_SSL_VERIFYPEER => false ]

    $client = new Client();
    $options = [
        'http_errors' => false,
        'force_ip_resolve' => 'v4',
        'connect_timeout' => 10,
        'read_timeout' => 10,
        'timeout' => 10,
        'verify' => false,
        'curl' => [ CURLOPT_SSL_VERIFYPEER => false ]
    ];
    $result = $client->request('GET',$url,$options);
    $result = json_decode((string) $result->getBody(), true);
    return $result;

I got

Try #3

removing 'force_ip_resolve' => 'v4',

    $client = new Client();
    $options = [
        'http_errors' => false,
        'connect_timeout' => 10,
        'read_timeout' => 10,
        'timeout' => 10,
        'verify' => false
    ];
    $result = $client->request('GET',$url,$options);
    $result = json_decode((string) $result->getBody(), true);
    return $result;

I got

---

Try #4

adding this line $result = $result->getCurlOptions()->set(CURLOPT_SSL_VERIFYPEER, FALSE);

    $client = new Client();
    $options = [
        'http_errors' => false,
        'force_ip_resolve' => 'v4',
        'connect_timeout' => 10,
        'read_timeout' => 10,
        'timeout' => 10,
        'verify' => false
    ];
    $result = $client->request('GET',$url,$options);
    $result = $result->getCurlOptions()->set(CURLOPT_SSL_VERIFYPEER, FALSE);
    $result = json_decode((string) $result->getBody(), true);
    return $result;

I got

Call to undefined method GuzzleHttp\\Psr7\\Response::getCurlOptions()

Questions

How would one go about and debug this further ?

I'm open to any suggestions at this moment.

Any hints/suggestions / helps on this be will be much appreciated!

Answer 1

the problem here is that $url is NOT a valid url, in fact, it seems your $url variable contains html. then you tell curl to connect to... this html, as an url, and curl says it cant find that domain. try giving a valid url (for example, hhtp://example.org ) as the $url parameter, and it should work fine.

Answer 2

The issue here is that you're trying to set the verify option on a response, at least for your third example

You can disable ssl verification in guzzle like so:

$client->getHttpClient()->setDefaultOption('verify', false); -- which actually, you already have, so in theory, you don't even need the line:

$result = $result->getCurlOptions()->set(CURLOPT_SSL_VERIFYPEER, FALSE);

As for #2, curl is indicating that you're passing the HTML of a page to the get method, not the URL, hence the unknown host error.

You were also calling json_decode on the response body, which isn't text, you need $response->getBody()->getContents(); , like so

public static function get($url){
    $options = [
        'http_errors' => false,
        'force_ip_resolve' => 'v4',
        'connect_timeout' => 10,
        'read_timeout' => 10,
        'timeout' => 10,
        'verify' => false
    ];
    $client = new Client($options);
    $result = $client->request('GET',$url);
    $result = json_decode($result->getBody()->getContents(), true);
    return $result;
}

Answer 3

You have 'force_ip_resolve' => 'v4', in all Guzzle's examples, but don't have the same option for cURL example. Try to remove it, unless you really need it.
