HttpURLConnection无效的HTTP方法：PATCH [英] HttpURLConnection Invalid HTTP method: PATCH

问题描述

当我尝试使用非标准HTTP方法（如PATCH和URLConnection）时：

When I try to use a non-standard HTTP Method like PATCH with URLConnection:

    HttpURLConnection conn = (HttpURLConnection) new URL("http://example.com").openConnection();
    conn.setRequestMethod("PATCH");

我得到一个例外：

java.net.ProtocolException: Invalid HTTP method: PATCH
at java.net.HttpURLConnection.setRequestMethod(HttpURLConnection.java:440)

使用像Jersey这样的更高级别的API会产生相同的错误。是否有解决方法来发出PATCH HTTP请求？

Using a higher level API like Jersey generates the same error. Is there a workaround to issue a PATCH HTTP request?

推荐答案

是否有解决方法。使用

X-HTTP-Method-Override

X-HTTP-Method-Override

。此标头可用于POST请求以伪造其他HTTP方法。只需将X-HTTP-Method-Override标头的值设置为您想要实际执行的HTTP方法即可。
所以请使用以下代码。

. This header can be used in a POST request to "fake" other HTTP methods. Simply set the value of the X-HTTP-Method-Override header to the HTTP method you would like to actually perform. So use following code.

conn.setRequestProperty("X-HTTP-Method-Override", "PATCH");
conn.setRequestMethod("POST");
