java程序访问http，或https最简单的方法_httpijctujvcv

首先要引入包http-request-5.6.jar 关于jar包，我已经是上传了哈。

注意：jar包调用详情说明地址：https://github.com/kevinsawicki/http-request/

下面代码其实就几句就行了，其他业务代码不必理会。

	/**
	 * this method is 授权
	 * @return
	 * @createTime 2015年1月5日 下午4:26:09

	public String accesstoken(){
		String url = "https://openapi.iqiyi.com/api/iqiyi/authorize?client_id="+appKey+"&client_secret="+appSecret;
		HttpRequest request = HttpRequest.get(url);
		//针对单项证书给予忽略（注意，双向证书需要导入证书文件）
		request.trustAllCerts();
		//信任所有地址
		request.trustAllHosts();
		String response = request.body();
		JSONObject jo = JSON.parseObject(response);
		Object code = jo.get("code");
		Object accessToken = jo.getJSONObject("data").get("access_token");
		System.out.println("Response was: " + response);
		System.out.println("code was: " + code);
		System.out.println("accessToken was: " + accessToken);
		return accessToken.toString();
