#okhttp封装

本文介绍了一个基于OkHttp的网络请求封装方案，通过创建BaseRequest类和OkHttpUtil工具类，支持GET、POST、PUT、DELETE四种HTTP方法，实现了请求的同步和异步处理，以及超时时间设置。

okhttp封装
需建BaseRequest类

public class OkHttpUtil {
public static Gson gson = new Gson();
//设置编码格式
public static final String METHOD_TYPE = “application/json; charset=utf-8”;
//四种模式
public static final String METHOD_GET = “GET”;
public static final String METHOD_POST = “POST”;
public static final String METHOD_PUT = “PUT”;
public static final String METHOD_DELETE = “DELETE”;
private static OkHttpClient sClient;

//单例模式
public OkHttpUtil(){}

public static void init(){
    sClient = new OkHttpClient.Builder()
    		//设置超时时间
            .connectTimeout(3000,TimeUnit.MICROSECONDS)
            //设置读写时间
            .writeTimeout(3000,TimeUnit.MICROSECONDS)
            .readTimeout(3000,TimeUnit.MICROSECONDS)
            .build();
}

//创建Request对象
private static Request creat(String url, String method, BaseRequest baseRequest){
    RequestBody requestBody = null;
    if(baseRequest!=null){
        String json = gson.toJson(baseRequest);
        MediaType parse = MediaType.parse(METHOD_TYPE);
        requestBody = RequestBody.create(parse, json);
    }
    Request.Builder builder = new Request.Builder().url(url);
    Request request = null;
    switch (method){
        case METHOD_GET:
            request = builder.build();
            break;
        case METHOD_POST:
            request = builder.post(requestBody).build();
            break;
        case METHOD_PUT:
            request = builder.put(requestBody).build();
            break;
        case METHOD_DELETE:
            if(requestBody != null){
                request = builder.delete(requestBody).build();
            }else{
                request = builder.delete().build();
            }
            break;
    }
    return request;
}

//封装异步get请求
public static void enqueueGet(String url, Callback callback,BaseRequest baseRequest){
    Request request = creat(url,METHOD_POST,baseRequest);
    Call call = sClient.newCall(request);
    call.enqueue(callback);
}

//封装同步post请求
public static Response executePost(String url,BaseRequest baseRequest) throws IOException {
    Request request = creat(url, METHOD_POST, baseRequest);
    Call call = sClient.newCall(request);
    Response response = call.execute();
    return response;
}

//同步get请求
public static Response executeGet(String url) throws IOException {
    Request request = creat(url, METHOD_GET, null);
    Call call = sClient.newCall(request);
    Response response = call.execute();
    return response;
}

}
