将PHP HTTP请求转换为Guzzle

我目前有一个旧的PHP页面，它执行一个对外部API的post请求，但我想将其转换为Guzzle来整理它，但我不确定我是否正确使用了它

PHP POST

 function http_post($server, $port, $url, $vars)
    {
        // get urlencoded vesion of $vars array
        $urlencoded = "";
        foreach ($vars as $Index => $Value)
            $urlencoded .= urlencode($Index) . "=" . urlencode($Value) . "&";
        $urlencoded = substr($urlencoded, 0, -1); 

        $headers = "POST $url HTTP/1.0\r\n";
        $headers .= "Content-Type: application/x-www-form-urlencoded\r\n";
        $headers .= "Host: secure.test.com\r\n";
        $headers .= "Content-Length: " . strlen($urlencoded)

        $fp = fsockopen($server, $port, $errno, $errstr, 20);  // returns file pointer
        if (!$fp) return "ERROR: fsockopen failed.\r\nError no: $errno - $errstr";  // if cannot open socket then display error message

        fputs($fp, $headers);

        fputs($fp, $urlencoded);

        $ret = "";
        while (!feof($fp)) $ret .= fgets($fp, 1024);
        fclose($fp);
        return $ret;
    }

$client = new Client();

$request = $client->request('POST','https://secure.test.com/callback/test.php', [
    // not sure how to pass the $vars from the PHP file
    'headers' => [
        'Content-Type' => 'application/x-www-form-urlencoded',
        'Host' => 'secure.test.com'
    ]
]);

$request->getBody()->getContents();

$client = new Client();

    $request = $client->get('https://secure.test.com/callback/test.php');
    
    $request->getBody()->getContents();

检索PHP响应

下面是如何检索响应的，您可以在其中使用$\u POST字段

 $response = http_post("https://secure.test", 443, "/callback/test.php", $_POST);

狂饮试贴

 function http_post($server, $port, $url, $vars)
    {
        // get urlencoded vesion of $vars array
        $urlencoded = "";
        foreach ($vars as $Index => $Value)
            $urlencoded .= urlencode($Index) . "=" . urlencode($Value) . "&";
        $urlencoded = substr($urlencoded, 0, -1); 

        $headers = "POST $url HTTP/1.0\r\n";
        $headers .= "Content-Type: application/x-www-form-urlencoded\r\n";
        $headers .= "Host: secure.test.com\r\n";
        $headers .= "Content-Length: " . strlen($urlencoded)

        $fp = fsockopen($server, $port, $errno, $errstr, 20);  // returns file pointer
        if (!$fp) return "ERROR: fsockopen failed.\r\nError no: $errno - $errstr";  // if cannot open socket then display error message

        fputs($fp, $headers);

        fputs($fp, $urlencoded);

        $ret = "";
        while (!feof($fp)) $ret .= fgets($fp, 1024);
        fclose($fp);
        return $ret;
    }

$client = new Client();

$request = $client->request('POST','https://secure.test.com/callback/test.php', [
    // not sure how to pass the $vars from the PHP file
    'headers' => [
        'Content-Type' => 'application/x-www-form-urlencoded',
        'Host' => 'secure.test.com'
    ]
]);

$request->getBody()->getContents();

$client = new Client();

    $request = $client->get('https://secure.test.com/callback/test.php');
    
    $request->getBody()->getContents();

狂饮尝试获得

 function http_post($server, $port, $url, $vars)
    {
        // get urlencoded vesion of $vars array
        $urlencoded = "";
        foreach ($vars as $Index => $Value)
            $urlencoded .= urlencode($Index) . "=" . urlencode($Value) . "&";
        $urlencoded = substr($urlencoded, 0, -1); 

        $headers = "POST $url HTTP/1.0\r\n";
        $headers .= "Content-Type: application/x-www-form-urlencoded\r\n";
        $headers .= "Host: secure.test.com\r\n";
        $headers .= "Content-Length: " . strlen($urlencoded)

        $fp = fsockopen($server, $port, $errno, $errstr, 20);  // returns file pointer
        if (!$fp) return "ERROR: fsockopen failed.\r\nError no: $errno - $errstr";  // if cannot open socket then display error message

        fputs($fp, $headers);

        fputs($fp, $urlencoded);

        $ret = "";
        while (!feof($fp)) $ret .= fgets($fp, 1024);
        fclose($fp);
        return $ret;
    }

$client = new Client();

$request = $client->request('POST','https://secure.test.com/callback/test.php', [
    // not sure how to pass the $vars from the PHP file
    'headers' => [
        'Content-Type' => 'application/x-www-form-urlencoded',
        'Host' => 'secure.test.com'
    ]
]);

$request->getBody()->getContents();

$client = new Client();

    $request = $client->get('https://secure.test.com/callback/test.php');
    
    $request->getBody()->getContents();

然后如何从响应中获取特定字段

从我上面的尝试中，我是否在正确的行上？

如果要将

$vars

作为POST请求主体发送，则需要设置属性

$client = new Client();

// get urlencoded vesion of $vars array
$urlencoded = "";
foreach ($vars as $Index => $Value)
    $urlencoded .= urlencode($Index) . "=" . urlencode($Value) . "&";
$urlencoded = substr($urlencoded, 0, -1); 

$response = $client->request('POST','https://secure.test.com/callback/test.php', [
    'headers' => [
        'Content-Type' => 'application/x-www-form-urlencoded',
        'Host' => 'secure.test.com'
    ],
    'body' => $urlencoded,
]);

如果您使用URLencode而不是

body

，Guzzle可以为您编码

$vars

$response = $client->request('POST','https://secure.test.com/callback/test.php', [
    'headers' => [
        'Content-Type' => 'application/x-www-form-urlencoded',
        'Host' => 'secure.test.com'
    ],
    'form_params' => $vars,
]);

要读取服务器的响应，您需要在

$response

上调用

getBody

，并将其强制转换为

string

。您将获得与原始

http\u post

函数返回值完全相同的返回值

$resultFromServer = (string) $response->getBody();

使用form_params解决方案，我还需要编写上面的编码吗？如果不存在$vars变量，那么$vars变量从何而来$urlencoded=“”；foreach（$vars as$Index=>$Value）$urlencoded.=urlencode（$Index）。"=" . urlencode（$Value）。"&"; $urlencoded=substr（$urlencoded，0，-1）；不，对于form_params，您只需将要发送到form_params键的变量分配给数组，Guzzle进行编码。我使用$vars，因为这是原始函数中使用的变量的名称。
