1.導入依賴

<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>3.14.0</version> </dependency>

2.代碼實現

package net.ruifeng.app.cloud.service.impl;import com.google.common.collect.Maps; import okhttp3.*;import java.io.IOException; import java.util.Map;public class Demo {public static final MediaType JSON = MediaType.parse("application/x-www-form-urlencoded; charset=utf-8");public static void main(String[] args) {try {Map<String, Object> param = Maps.newHashMap();param.put("jcgl",1);param.put("putPrice",1);param.put("total",1);param.put("transactiontype",1);param.put("valuation",1);RequestBody loginBody =RequestBody.create(JSON, com.alibaba.fastjson.JSON.toJSONString(param));Response response = httpPost("http://192.161.1.1:8888/order/saveData", loginBody);System.out.println(response);} catch (Exception e) {e.printStackTrace();}}public static Response httpPost(String url, RequestBody requestBody) throws IOException {OkHttpClient client = new OkHttpClient();Request request=new Request.Builder().url(url).post(requestBody).addHeader("Content-Type", "application/x-www-form-urlencoded").build();Response response = client.newCall(request).execute();if (response.isSuccessful()) {return response;} else {throw new IOException("Unexpected code " + response);}} }
