OKGO【配置】
首先在Application里的onCreate()里面初始化网络配置
/**
* 初始化OKgo的环境配置【可选】
*/
private void initOkHttp() {
//使用OkGo内置的log拦截器打印log，如果你觉得不好用，也可以自己写个，这个没有限制。
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor("okgo");
//log打印级别，决定了log显示的详细程度
interceptor.setPrintLevel(HttpLoggingInterceptor.Level.BODY);
//log颜色级别，决定了log在控制台显示的颜色
interceptor.setColorLevel(Level.INFO);
OkHttpClient.Builder builder = new OkHttpClient.Builder();
//全局的读取超时时间 十分钟
builder.readTimeout(60 * 1000 * 10, TimeUnit.MILLISECONDS);
//全局的写入超时时间 十分钟
builder.writeTimeout(60 * 1000 * 10, TimeUnit.MILLISECONDS);
//全局的连接超时时间 十分钟
builder.connectTimeout(60 * 1000 * 10, TimeUnit.MILLISECONDS);
builder.addInterceptor(interceptor);
OkHttpClient client = builder.build();
OkGo.getInstance().init(this).setOkHttpClient(client);
//可以设置同时上传的任务数量，如果不设置，默认就是1个，改方法只在第一次调用时生效，以后无效,必须在首次执行前设置，否者无效 ,范围1-5之间
OkUpload.getInstance().getThreadPool().setCorePoolSize(4);
OkDownload.getInstance().setFolder(FileUtils.path);
OkDownload.getInstance().getThreadPool().setCorePoolSize(4);
}例如：
配置网络请求工具类【这是我自己写的】

}
/**
* 上传json字符串
*
* @param adress_Http 地址
* @param strJson json字符串
* @return
*/
public static int postJson(String adress_Http, String strJson) {
String returnLine = "";
int code = 0;
try {
System.out.println("**************调用的接口地址为**************" + adress_Http);
System.out.println("**************请求发送的数据为**************" + strJson);
URL my_url = new URL(adress_Http);
HttpURLConnection conn = (HttpURLConnection) my_url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
conn.setUseCaches(false);
conn.setConnectTimeout(30 * 1000);
conn.setReadTimeout(30 * 1000);
// connection.setInstanceFollowRedirects(true);
conn.setRequestProperty("Charsert", "UTF-8");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Connection", "Keep-Alive");
Map> requestProperties = conn.getRequestProperties();
DataOutputStream out = new DataOutputStream(conn
.getOutputStream());
byte[] content = strJson.getBytes();
out.write(content);
out.flush();
out.close(); // flush and close
code = conn.getResponseCode();
//读
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
//StringBuilder builder = new StringBuilder();
String line = "";
System.out.println("Contents of post request start");
while ((line = reader.readLine()) != null) {
returnLine += line;
System.out.println(line);
}
System.out.println("Contents of post request ends");
reader.close();
conn.disconnect();
System.out.println("========返回的结果的为========" + returnLine);
} catch (Exception e) {
e.printStackTrace();
}
return code;
}
}
这是使用：我统一处理返回值了，如果你不需要的话，可以省略这一步
