How to Get Body content of HTTPS using CURL
提问by Stephen Baugh
The following code will retrieve the body content of a url retrieved using CURL in php but not https. Can anyone tell me how I edit the code as I need to get the data returned not just the header.
以下代码将检索在 php 中使用 CURL 检索的 url 的正文内容，但不检索 https。谁能告诉我如何编辑代码，因为我需要返回的数据不仅仅是标题。
From the test I did here is the result. You can see it has a content-length, I just don't know how to access it.
从我在这里做的测试是结果。你可以看到它有一个内容长度，我只是不知道如何访问它。
Thanks Stephen
谢谢斯蒂芬

Here is the solution: Try this, just keep rest of the coding same as above...
这是解决方案：试试这个，只需保持与上述相同的其余编码...
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
// curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_URL, $fullurl);
$returned = curl_exec($ch);
curl_close ($ch);
var_dump($returned);
Changing CURLOPT_HEADER to 0 makes it so that only the page content is returned.
将 CURLOPT_HEADER 更改为 0 使其仅返回页面内容。
回答by Josh
Shouldn't $fullurlbe "https://www.queensberry.com" ?
不应该$fullurl是“ https://www.queensberry.com”吗？
When I changed $fullurlas stated and ran the code, var_dumpdisplayed the "under construction" page.
当我$fullurl按照说明进行更改并运行代码时，var_dump显示“正在建设中”页面。

if you still need the header, which means setting CURLOPT_HEADER to 0 is not an option, you can find the start of the body by looking for an empty line (two CRLF). See the spec: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html
如果您仍然需要标题，这意味着将 CURLOPT_HEADER 设置为 0 不是一个选项，您可以通过查找空行（两个 CRLF）来找到正文的开头。请参阅规范：http: //www.w3.org/Protocols/rfc2616/rfc2616-sec6.html
so this should do the job:
所以这应该可以完成这项工作：
$data = curl_exec($ch);
$start = strpos($data, "\r\n\r\n") + 4;
$body = substr($data, $start, strlen($data) - $start);

I look for the length of the header using the curl's getinfo. Then substring the response:
我使用 curl 的 getinfo 查找标题的长度。然后子字符串响应：
$info = curl_getinfo($ch);
$start = $info['header_size'];
$body = substr($result, $start, strlen($result) - $start);
