Question

<?php 
$curl = curl_init (); 
$headers = array ( 
    "Content-Type: application/json", 
    "ulogin : abc",           
    "Authorization : abcdefgh"
); 
curl_setopt ( $curl, CURLOPT_HTTPHEADER, $headers );
curl_setopt ( $curl, CURLOPT_URL, "http://localhost:8080/api/orders/209");
curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );

$result = curl_exec ( $curl );

if ($result === false) {
   die ( 'Error fetching data: ' . curl_error ( $curl ) );
} else {
   var_dump ( $result );
}
curl_close ( $result );

?>

url是一个java rest api服务。在服务端收到此GET请求时，显示所有标头值为null。我用邮递员测试了服务，并设置了标题，然后通过。不确定我在PHP代码中缺少什么。

我服务的代码段：

public void doFilter(ServletRequest req, ServletResponse res,
        FilterChain chain) throws IOException, ServletException {
    final HttpServletRequest httpRequest = (HttpServletRequest) req;
        String token = httpRequest.getHeader("Authorization");
        String userEmail = httpRequest.getHeader("ulogin");
}

更新
我用postman和一个示例java客户端测试过。两者都有效。只有从php才能正常工作。

     public static void main(String[] args) throws ClientProtocolException, IOException {
      HttpClient client = new DefaultHttpClient();
      HttpGet request = new HttpGet("http://localhost:8080/api/order/165");
      request.addHeader("Content-Type", "application/json");
      request.addHeader("ulogin", "abc");         r 
      request.addHeader("Authorization", "abcdefg");
      HttpResponse response = client.execute(request);
      BufferedReader rd = new BufferedReader (new InputStreamReader(response.getEntity().getContent()));
      System.out.println( response.getHeaders("Authorization"));

     }

UPDATE2

使用get_file_contents也可以

  $url = "http://localhost:8080/api/order/165";

  $options = array(
 'http'=>array(
 'method'=>"GET",
 'header'=>"Content-Type: application/json\r\n" .
          "ulogin: abc\r\n" .     
          "Authorization:abcdefg\r\n"       
  )
  );

  $context = stream_context_create($options);
  $file = file_get_contents($url, false, $context);
  var_dump($file);

Answer 1

我不确定，但如果你想要包含标题，则有一个选项

CURLOPT_HEADER  TRUE to include the header in the output.

Php.net CURL

Answer 2

如何在php中设置标头没有任何问题。

当你调用一个显示请求标题的php脚本时，它会显示你设置的3个标题。将以下代码粘贴到新的php文件中，并使用当前代码调用它。你会发现它很棒。

var_dump(getallheaders());

curl_close中的一个小注释，你需要添加curl处理程序而不是你解析的结果。更改以下行

curl_close ( $result );

要

curl_close( $curl );

使用php在CURL中设置客户标题不起作用
