okhttp使用
前期准备
- 引入对应的jar包
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.0.1</version>
</dependency>
post请求
@Test
public void test3() {
MediaType JSON
= MediaType.get("application/json; charset=utf-8");
OkHttpClient client = new OkHttpClient();
JSONObject json = new JSONObject();
json.put("ledger", "22");
RequestBody body = RequestBody.create(JSON, json.toJSONString());
Request request = new Request.Builder()
.url("http://localhost/cost-test-service/testGet")
.post(body)
.build();
try (Response response = client.newCall(request).execute()) {
System.out.println("##result##" + response.body().string());
} catch (Exception e) {
}
}
登录后发送post请求
