Php 返回失败

已解决

感谢@ramraider提供解决方案

解决方案（$field\u字符串需要包含原始URL，并且还需要传递到curl\u setop（）中）

我有一个简单的HTML网络表单，它可以发布到一个php文件中。在这个php文件中有一个简单的cURL请求。问题是他们（领导管理公司的服务器）不断返回一个“失败”响应。他们非常吝啬地向我提供任何原因，并且不提供任何日志，这样我就可以看到流程失败的地方。他们甚至告诉我我需要使用GET而不是POST，这不仅是他们的文档推荐的POST，而且GET不起作用我已经打印了尽可能多的调试信息，以了解问题所在

如果我复制submission$url并将其与$field_字符串结果结合起来，然后直接在我的浏览器中提交它-它是有效的！因此，我的代码中一定有某种东西会将其丢弃，但在我自己花了整整两天的时间试图研究和解决它之后，我终于请求帮助了

非常感谢您的指导，谢谢

请注意，出于隐私原因，我遗漏了一些URL信息

代码：

//extract data from the post
//set POST variables
$url = 'https://website.com/Import.aspx?';
$fields = array(
    'Provider'=> 'SabbaraWebsiteGET',
    'Client'=>'SabbaraGroup',
    'CampaignId'=>'1064',
    'first_name' => urlencode($_POST['first_name']),
    'last_name' => urlencode($_POST['last_name']),
    'user_email' => urlencode($_POST['email']),
    'phone' => urlencode($_POST['phone']),
    'current_payment' => urlencode($_POST['current_payment']),
    'type_loan' => urlencode($_POST['type_loan']),
    'reason_application' => urlencode($_POST['reason_application']),
);

//url-ify the data for the POST
$field_string = http_build_query($fields, '', '&');

//open connection
$ch = curl_init($url);

//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);

//execute post
$response = curl_exec($ch);

// DEBUGGING
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
echo '<pre>

Request Header:
'.curl_getinfo($ch,CURLINFO_HEADER_OUT ).'
'.$field_string.'

Response:
'.$response.'
</pre>';

$info = curl_getinfo($ch);
echo "\n\n" . 'Took '. $info['total_time']. ' seconds to send a request to '. $info['url']. ' CODE: '.$info['http_code']."\n";

//close connection
curl_close($ch);

您的代码尝试使用

$field\u string

来

url-ify

发送数据，但是您将

$fields

作为数据发送-在我看来，这会产生不同的结果，因为一个发送数据作为

多部分/表单数据

，另一个发送数据作为

应用程序/x-www-form-urlcoded

，因此主机可能期望不同的内容键入header？另外，我建议将

CAINFO

参数添加到curl请求中。非常感谢！您的评论将我疲惫的眼睛指向了正确的方向。我将代码更改为：'//url为POST$field_string=$url.http_build_query（$fields，，'&'）；//打开连接$ch=curlinit（$field_string）；//设置url、POST变量的数量、POST数据curl_setopt（$ch，CURLOPT_POST，1）；curl_setopt（$ch，CURLOPT_POSTFIELDS，$field_string）；“这就成功了！另外，谢谢你关于添加CAINFO的建议-我现在正在研究这个问题。再次感谢你！很高兴你疲惫的眼睛得到了一些缓解
