我想加载此链接。但我得到一些错误。返回http是好的。这是怎么回事？

Answer 1

问题是，如果我正确理解您认为标题信息是错误的，很可能是因为您向主体curl_setopt($ch, CURLOPT_HEADER, 1);请求标题信息。尝试删除该行，你应该得到正文输出。

如果您想要单独返回标题信息，可以尝试使用CURLOPT_HEADERFUNCTION，请参阅https://curl.haxx.se/libcurl/c/CURLOPT_HEADER.html

Answer 2

您需要从curl请求中显式检索响应正文。见Can PHP cURL retrieve response headers AND body in a single request?

PHP / cURL一个网站
