http作为最常用的网络请求方式，用来交换数据，不同的http客户端，性能使用方式都有所差别，本文将对HttpClient,okhttp,Jodd-http三者的put，post请求方式做一个对比。

发送请求主要分为以下几步：
@Test public void testApacheHttpGet(String url) throws IOException { //设置超时时间 RequestConfig config = RequestConfig.custom() .setConnectTimeout(60 * 1000) //连接超时时间 .setSocketTimeout(60 * 1000) //从服务器获取响应数据的超时时间 .build(); CloseableHttpClient client = HttpClientBuilder.create().build(); HttpGet httpGet = new HttpGet(url); httpGet.setConfig(config); CloseableHttpResponse response = client.execute(httpGet); System.out.println(EntityUtils.toString(response.getEntity())); }
@Test public void testApacheHttpPost(String url) throws IOException { CloseableHttpClient client = HttpClientBuilder.create().build(); HttpPost httpPost = new HttpPost(url); httpPost.setHeader("Content-Type", "application/json;charset=utf8"); httpPost.setEntity(new StringEntity(new JSONObject().toString())); //设置请求体 CloseableHttpResponse response = client.execute(httpPost); System.out.println(EntityUtils.toString(response.getEntity())); }
发送请求主要分为以下几步：
@Test
public void testOkHttpGet(String url) throws IOException {
Request request = new Request.Builder()
.url(url)
.get()
.build();
Call call = okHttpClient.newCall(request);
Response response = call.execute();
System.out.println(response.body().toString());
}
@Test
public void testOkHttpPost(String url) throws IOException {
JSONObject json = new JSONObject();
RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=utf-8"),String.valueOf(json));
Request build = new Request.Builder()
.url(url)
.post(body)
.header("Content-Type","application/json;charset=utf8")
.build();
Call call = okHttpClient.newCall(build);
Response response = call.execute();
String string = response.body().string();
}
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(60, TimeUnit.SECONDS)//设置连接超时时间
.readTimeout(60, TimeUnit.SECONDS)//设置读取超时时间
.build();
对client设置超时，意味着所有请求方式都将采取此种超时设置。
Jodd提供的一个轻量级、原生的的http客户端，使用起来很简单、方便。
请求参数可以直接拼接在url后面，也可以通过query()方法指定
@Test public void testJoddHttpGet(String url) throws IOException { HttpResponse response = HttpRequest .get(url) //指定请求方式 .contentType("application/json") //指定编码方式 .query("xxx", "xxx") .connectionKeepAlive(true)//长连接 .timeout(60 * 1000) //超时设置 .send(); //发送请求 System.out.println(response.bodyText()); }
response存储服务器返回的数据。可以从response实例中提取出各种属性，如statusCode()或者statusPhrase()。
response读取响应body有三种方法：
response.bodyText() body文本，以头信息指定的方式编码
response.bodyBytes() body字节
response.body() 以ISO-8859-1 encoding
请求体存放在bodyText中。也可以通过form("xx","xx")表单加参数
public void testJoddHttpPost(String url) throws IOException { HttpResponse response = HttpRequest .post(url) .contentType("application/json") .bodyText("xxx") .send(); System.out.println(response.bodyText()); }
HttpClient,okhttp,Jodd-http 使用上的差异
