背景
之前在spring上面使用過okhttp：spring傳統xml配置okhttp3
Component
package com.zyl.config;
import okhttp3.ConnectionPool;
import okhttp3.Credentials;
import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
import java.util.concurrent.TimeUnit;
/** okhttp3 configuration */
@Component
public class OkHttpConfiguration {
private Logger logger = LoggerFactory.getLogger(OkHttpConfiguration.class);
/**
* 爲新連接設置默認連接超時，單位毫秒
*/
@Value("${connectTimeout:10000}")
private long connectTimeout;
/**
* true表示啓用連接池，false表示不啓用連接池
*/
@Value("${connectionPoolEnable:true}")
private boolean connectionPoolEnable;
/**
* sap的基本認證
*/
@Value("${username:zyl}")
private String username;
/**
* sap的基本認證
*/
@Value("${password:xxxyyy}")
private String password;
@Bean
public OkHttpClient okHttpClient(){
OkHttpClient.Builder builder = new OkHttpClient.Builder();if (connectionPoolEnable){
builder.connectionPool(new ConnectionPool());
}
builder.connectTimeout(connectTimeout, TimeUnit.MILLISECONDS);
builder.authenticator((route, response) -> {
if (response.request().header("Authorization") != null) {
return null; // Give up, we've already attempted to authenticate.
}
logger.info("Authenticating for response: " + response);
logger.info("Challenges: " + response.challenges());
String credential = Credentials.basic(username, password);
return response.request().newBuilder()
.header("Authorization", credential)
.build();
});
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BASIC);
builder.addInterceptor(logging);
return builder.build();
}
}
運行時配置中心，現在還玩不6。
Controller
@Autowired
private OkHttpClient okHttpClient;
在控制器中使用：
Request request = new Request.Builder()
.url("https://www.google.com/ncr")
.addHeader("myheader", "hello header")
.get()
.build();
Response response = null;
try {
response = okhttpClient.newCall(request).execute();
response.body().string();
} catch (IOException e) {
e.printStackTrace();
} finally {
if(response != null) {
response.close();
}
}
