java如何执行HTTP删除？我得到的只是网址

Question

我只是一个java初学者，想知道如何对URL进行HTTP Delete调用。 任何一小段代码或参考资料都会非常有用

我知道这个问题听起来很简单，但我急需这个信息

Answer 1

您还可以尝试ApacheHttpClient，它为所有HTTP方法（GET、PUT、DELETE、POST、OPTIONS、HEAD和TRACE）提供API

查看这里的示例：http://hc.apache.org/httpclient-3.x/methods/delete。 API引用在这里：http://hc.apache.org/httpclient-3.x/apidocs/index.html

干杯

Answer 2

您可以使用Restlet。这是一个很好的客户端API。或者你可以做如下的事情

URL url = new URL("http://www.example.com/resource");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestProperty(
    "Content-Type", "application/x-www-form-urlencoded" );
httpCon.setRequestMethod("DELETE");
httpCon.connect();
httpCon.getInputStream()

Answer 3

DELETE、PUT、OPTIONS方法受大多数服务器的限制。以下是关于SO中此主题的良好讨论。 Are the PUT, DELETE, HEAD, etc methods available in most web browsers?

Answer 4

我想你可以这样称呼：

URL url = new URL("http://www.abcd.com/blog");
HttpURLConnection httpConnection = (HttpURLConnection) url.openConnection();
httpConnection.setDoOutput(true);
httpConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded" );
httpConnection.setRequestMethod("DELETE");
httpConnection.connect();

Answer 5

实际上发送HttpDelete与HttpGet类似，首先您将使用所有参数构建url，然后只执行请求，测试以下代码

    StringBuilder urlBuilder = new StringBuilder(Config.SERVER)
            .append("/api/deleteInfo?").append("id=")
            .append(id);
    urlBuilder.append("&people=").append(people).toString();

    try {

        HttpClient httpClient = new DefaultHttpClient();
        HttpDelete httpDelete = new HttpDelete(urlBuilder.toString());
        HttpResponse httpResponse = httpClient.execute(httpDelete);
        HttpEntity entity = httpResponse.getEntity();
        final String response = EntityUtils.toString(entity);
        Log.d(TAG, "content = " + response);
    } catch (final Exception e) {
        e.printStackTrace();
        Log.d(TAG, "content = " + e.getMessage());
    } catch (OutOfMemoryError e) {
        e.printStackTrace();
        System.gc();
    }
