HTTP HTTPS java爬虫 状态= 405 403 解决方法

 

常会遇到状态405错误，因为大多数wed服务器不允许静态文件响应post请求，只需要把post 改为get就可以运行.

public static String givenRedirecting(String pageUrl) throws ClientProtocolException, IOException {
        HttpClient instance = HttpClientBuilder.create().setRedirectStrategy(new LaxRedirectStrategy()).build();
        org.apache.http.HttpResponse response = instance.execute(new HttpGet(pageUrl));
        String html = EntityUtils.toString(response.getEntity(), "gbk");
        return html;
    }

 

HTTPS 问题

在请求前加上  

System.setProperty("https.protocols", "TLSv1.2,TLSv1.1,SSLv3");
