调用声网(agora)的远程接口(Restful Api)时,对方需要使用Basic Auth的方式进行认证(需要输入用户名和密码)。
一,使用Postman完成基于Basic Auth的Http认证方式
二,在代码中如何调用呢?
1.当我们使用HttpUtil工具类模拟浏览器调用时,需要在header设置Authorization属性
创建Http Get请求时,设置header。修改HttpUtil工具类中的Get方法,添加如下代码:
// 创建http GET请求
//修改前: //HttpGet httpGet = new HttpGet(uri);
//---------------------------------------
//修改后:
HttpGet httpGet = new HttpGet(uri); List<NameValuePair> params = new ArrayList<NameValuePair>(); if(param==null){ params=null; } RequestBuilder requestBuilder = RequestBuilder.get().setUri(new URI(url)); requestBuilder.setEntity(new UrlEncodedFormEntity(params, Consts.UTF_8)); httpGet.setHeader( new BasicHeader("Content-Type", param.get("Content-Type"))); httpGet.setHeader(new BasicHeader("Accept", "text/plain;charset=utf-8")); httpGet.setHeader("Authorization",param.get("Authorization"));
2.完整HttpUtil工具类:
package com.yishang.utils; import org.apache.http.Consts; import org.apache.http.NameValuePair; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpGet; import org.apache.http.client.methods.HttpPost; import org.apache.http.client.methods.RequestBuilder; import org.apache.http.client.utils.URIBuilder; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.message.BasicHeader; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; import java.io.IOException; import java.net.URI; import java.util.ArrayList; import java.util.List; import java.util.Map; public class HttpUtils { public static String doGet(String url, Map<String, String> param) { // 创建Httpclient对象 CloseableHttpClient httpclient = HttpClients.createDefault(); String resultString = ""; CloseableHttpResponse response = null; try { // 创建uri URIBuilder builder = new URIBuilder(url); if (param != null) { for (String key : param.keySet()) { builder.addParameter(key, param.get(key)); } } URI uri = builder.build(); // 创建http GET请求 //HttpGet httpGet = new HttpGet(uri); HttpGet httpGet = new HttpGet(uri); List<NameValuePair> params = new ArrayList<NameValuePair>(); if(param==null){ params=null; } RequestBuilder requestBuilder = RequestBuilder.get().setUri(new URI(url)); requestBuilder.setEntity(new UrlEncodedFormEntity(params, Consts.UTF_8)); httpGet.setHeader( new BasicHeader("Content-Type", param.get("Content-Type"))); httpGet.setHeader(new BasicHeader("Accept", "text/plain;charset=utf-8")); httpGet.setHeader("Authorization",param.get("Authorization")); // 执行请求 response = httpclient.execute(httpGet); // 判断返回状态是否为200 if (response.getStatusLine().getStatusCode() == 200) { resultString = EntityUtils.toString(response.getEntity(), "UTF-8"); } } catch (Exception e) { e.printStackTrace(); } finally { try { if (response != null) { response.close(); } httpclient.close(); } catch (IOException e) { e.printStackTrace(); } } return resultString; } public static String doGet(String url) { return doGet(url, null); } public static String doPost(String url, Map<String, String> param) { // 创建Httpclient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpResponse response = null; String resultString = ""; try { // 创建Http Post请求 HttpPost httpPost = new HttpPost(url); // 创建参数列表 if (param != null) { List<NameValuePair> paramList = new ArrayList<>(); for (String key : param.keySet()) { paramList.add(new BasicNameValuePair(key, param.get(key))); } // 模拟表单 UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramList); httpPost.setEntity(entity); } // 执行http请求 response = httpClient.execute(httpPost); resultString = EntityUtils.toString(response.getEntity(), "utf-8"); } catch (Exception e) { e.printStackTrace(); } finally { try { response.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return resultString; } public static String doPost(String url) { return doPost(url, null); } }
3.使用HttpUtil的Get方法调用声网的Restful Api:
/* http的 basic Auth认证方式 */ String username = "yourusername"; String password = "yourpassword"; String userMsg = username + ":" + password; String base64UserMsg = Base64.encodeBase64String(userMsg.getBytes()); String authorization="Basic "+base64UserMsg; String content_type = "application/x-www-form-urlencoded"; Map<String,String> params = new HashMap<String, String>(); params.put("Authorization", authorization); params.put("Content-Type", content_type); String url = "http://api.agora.io/dev/v1/projects"; String resultProjects = HttpUtils.doGet(url,params);
