plateye公开API调用问题

如何连接plateye提供的公开API?https://api.plateye.com/origin/docs/#/home

网页文档host已经更新,请求域名:https://api.plateye.com/,
请求示例 https://api.plateye.com/api/home/chainStatistic

https://api.plateye.com/ 报403

用POST请求 调用https://api.plateye.com/,不是直接打开,具体也可以看请求示例 https://api.plateye.com/api/home/chainStatistic

请求示例看不了啊

这也是个Post请求调用

/**
* 发起https请求并获取结果
*
* @param requestUrl 请求地址
* @param requestMethod 请求方式(GET、POST)
* @param outputStr 提交的数据
* @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值)
*/
public static JSONObject HttpRequest(String request , String RequestMethod , String output ){
@SuppressWarnings(“unused”)
JSONObject jsonObject = null;
StringBuffer buffer = new StringBuffer();
try {
//建立连接
URL url = new URL(request);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
connection.setRequestMethod(RequestMethod);
//设置请求内容编码格式
connection.setRequestProperty(“content-type”, “application/x-www-form-urlencoded”);

		if(output!=null){
			OutputStream out = connection.getOutputStream();
			out.write(output.getBytes("UTF-8"));
			out.close();
		}
		//流处理
		InputStream input = connection.getInputStream();
		InputStreamReader inputReader = new InputStreamReader(input,"UTF-8");
		BufferedReader reader = new BufferedReader(inputReader);
		String line;
		while((line=reader.readLine())!=null){
			buffer.append(line);
		}
		//关闭连接、释放资源
		reader.close();
		inputReader.close();
		input.close();
		input = null;
		connection.disconnect();
		jsonObject = JSONObject.fromObject(buffer.toString());
	} catch (Exception e) {
	}
	return jsonObject;
