Get header from HttpResponse in Android
提问by Radu Stoenescu
Is there a way to get the value of a specific header using the HttpResponseobject returned by the HttpClientexecute()method in Android?
有没有办法使用Android中方法HttpResponse返回的对象获取特定标头的值HttpClientexecute()？
采纳答案by Rob Hruska
There are several ways to get specific headers. HttpResponseinherits from HttpMessage, which provides the following header retrieval methods:
有几种方法可以获取特定的标头。HttpResponse继承自HttpMessage，它提供以下标头检索方法：
In your case, you probably want getFirstHeader(String). Headers can contain multiple values, hence the Header[]array return from getHeaders(); if you only expect there to be a single header, getFirstHeader(String)should suffice.
在您的情况下，您可能想要getFirstHeader(String). 标头可以包含多个值，因此Header[]数组从getHeaders(); 如果您只希望有一个标题，getFirstHeader(String)就足够了。

Please try HttpResponse.getAllHeaders()for printing headers and for printing cookie in Headers.
请尝试HttpResponse.getAllHeaders()打印标题并在标题中打印 cookie。
response.getHeaders("Set-Cookie")

try the below method :-
试试下面的方法：-
URL obj = new URL("http://mkyong.com");
URLConnection conn = obj.openConnection();
Map<String, List<String>> map = conn.getHeaderFields();
System.out.println("Printing Response Header...\n");
for (Map.Entry<String, List<String>> entry : map.entrySet()) {
System.out.println("Key : " + entry.getKey()
+ " ,Value : " + entry.getValue());
}
System.out.println("\nGet Response Header By Key ...\n");
String server = conn.getHeaderField("Server");
if (server == null) {
System.out.println("Key 'Server' is not found!");
} else {
System.out.println("Server - " + server);
}
System.out.println("\n Done");
} catch (Exception e) {
e.printStackTrace();
}

I always use this code
我总是使用这个代码
Initially, I do so
最初，我这样做
Header[] headers = response.getAllHeaders();
Next, I'm using a simple method converts in hashmap
接下来，我在 hashmap 中使用了一个简单的方法转换
private HashMap<String, String> convertHeadersToHashMap(Header[] headers) {
HashMap<String, String> result = new HashMap<String, String>(headers.length);
for (Header header : headers) {
result.put(header.getName(), header.getValue());
}
return result;
}
Now I can get any value
现在我可以得到任何价值
Maybe someone can help Good luck
也许有人可以帮助祝你好运
