问题描述

我可以使用 CURLOPT_HTTPHEADER 多次调用 curl_setopt 来设置多个标头吗?

Can I call curl_setopt with CURLOPT_HTTPHEADER multiple times to set multiple headers?

$url = 'http://www.example.com/';

$curlHandle = curl_init($url);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Authorization: gfhjui'));

$execResult = curl_exec($curlHandle);

推荐答案

遵循 curl 在内部为请求所做的事情(通过 这个对Php - Debugging Curl"的回答)回答了这个问题:否.

Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No.

不，不可能将 curl_setopt 调用与 CURLOPT_HTTPHEADER 一起使用多次，每次都传递一个标头，以便设置多个标头.

No, it is not possible to use the curl_setopt call with CURLOPT_HTTPHEADER more than once, passing it a single header each time, in order to set multiple headers.

第二次调用将覆盖前一次调用的标头(例如第一次调用的标头).

A second call will overwrite the headers of a previous call (e.g. of the first call).

相反，该函数需要使用所有标头调用一次:

Instead the function needs to be called once with all headers:

$headers = array(
    'Content-type: application/xml',
    'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

• 如何获取之前使用 curl_setopt() 设置的选项?(curl PHP 扩展)
