[网络协议]异步http请求处理机制

现在开源的http请求库有很多，但是呢，有时候总有些不合适的地方，然后呢我就自己摸索的一套异步http请求处理机制；
1:get/post 请求
2:多种方式携带token，并有token过期、失效等处理机制；
3:使用简单，几行代码搞定一个请求，只需专注业务实现；
话不多说，直接上代码

1:首先是创建几个实体类，用于接收请求的结果以及内容
Result.calss ：请求的结果的实体类

public class Result {
    public Boolean isSuccess;//返回结果
    public ResultInfo result;//返回内容
    public String resultDes;//返回结果描述(成功，错误等)

    public Boolean isSuccess() {
        return isSuccess;
    }

    public void setSuccess(Boolean success) {
        isSuccess = success;
    }

    public ResultInfo getResult() {
        return result;
    }

    public void setResult(ResultInfo result) {
        this.result = result;
    }

    public String getResultDes() {
        return resultDes;
    }

    public void setResultDes(String resultDes) {
        this.resultDes = resultDes;
    }

    @Override
    public String toString() {//一般用于日志打印
        StringBuffer SB = new StringBuffer();
        SB.append("------------------------------");
        SB.append(isSuccess);
        SB.append("------------------------------");
        SB.append("\n");
        SB.append("------------------------------");
        SB.append(resultDes);
        SB.append("------------------------------");
        SB.append("\n");
        SB.append(result.toString());
        return SB.toString();
    }
}

ResultInfo.calss：返回内容的实体类

public class ResultInfo<T> implements java.io.Serializable {

    public int code;

    public String message;

    public T data;

    public ResultPage page;

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public ResultPage getPage() {
        return page;
    }

    public void setPage(ResultPage page) {
        this.page = page;
    }

    @Override
    public String toString() {
        StringBuffer SB = new StringBuffer();
        SB.append("code=" + code);
        SB.append("\n");
        SB.append("message=" + message);
        if(data!=null){
            SB.append("\n");
            SB.append("data=" + data.toString());
        }
        if(page!=null){
            SB.append("\n");
            SB.append("page=" + page.toString());
        }

        return SB.toString();
    }
}

URL及配置等实体类
UrlInfo.calss

public class UrlInfo {
    String URL = "";
    String ContentType = null;
    String token = "";

    public String getContentType() {
        return ContentType;
    }

    public void setContentType(String contentType) {
        ContentType = contentType;
    }

    @Override
    public String toString() {
        return "UrlInfo{" +
                "URL='" + URL + '\'' +
                ", params='" + params + '\'' +
                '}';
    }

    public void setURL(String URL) {
        this.URL = URL;
    }

    public String getURL() {
        return URL;
    }

    String params = "";

    public void setParams(String params) {
        this.params = params;
    }

    public String getParams() {
        return params;
    }

    public void addParams(String key, Object value) {
        StringBuffer pa = new StringBuffer();
        if (!params.equals("")) {
            pa.append(params);
            pa.append("&");
        }
        pa.append(key);
        pa.append("=");
        pa.append(value.toString());
        params = pa.toString();
    }
}

接下来就是正式开始请求数据了，我只是实现了常用的POST和GET请求，其他的各位可以按需自己实现步骤是一样的；
首先是创建实际请求的方法类
注意：我这里这里用到了JSON解析库，用于将返回的内容序列化；

！！！注意：代码中上传下载的写的时间已经比较久远，当时都是可用的，但考虑到Android 在储存这块的限制增加，不敢保证慎用！

接下来就是通过异步将内容返回给视图层；
HttpAsyncTask.class

import android.os.AsyncTask;

import java.lang.reflect.Type;

public class HttpAsyncTask<T> {
    UrlInfo mUrlInfo;
    public static final int HTTP_TYPE_POST = 0;
    public static final int HTTP_TYPE_GET = 1;

    /**

        }

    }

        this.onResult = onResult;
        this.mUrlInfo = mUrlInfo;
        if (HTTP_TYPE == HTTP_TYPE_GET) {
            new getResultAsyncTask().execute(type);
        } else {
            new postResultAsyncTask().execute(type);
        }

    }


    /**
     * 此方法返回的数据类型为String
     *

     */
    public HttpAsyncTask(UrlInfo mUrlInfo, onResult onResult) {
        this.onResult = onResult;
        this.mUrlInfo = mUrlInfo;
    }


    class getResultAsyncTask extends AsyncTask<Type, Integer, Result> {

        @Override
        protected Result doInBackground(Type... types) {
            HttpClient mHttpClient = new HttpClient<T>(mUrlInfo);
            Result result;
            if (types != null && types.length > 0)
                result = mHttpClient.Get(types[0]);
            else
                result = mHttpClient.Get(null);
            return result;
        }

        protected void onPostExecute(Result result) {
            OnPostExecute(result);
        }
    }

    class postResultAsyncTask extends AsyncTask<Type, Integer, Result> {

        @Override
        protected Result doInBackground(Type... types) {
            HttpClient<T> mHttpClient = new HttpClient(mUrlInfo);
            Result result;
            if (types != null && types.length > 0)
                result = mHttpClient.Post(types[0]);
            else
                result = mHttpClient.Post(null);
            return result;
        }

        protected void onPostExecute(Result result) {
            OnPostExecute(result);
        }
    }

    void OnPostExecute(Result result) {
        if (result.isSuccess) {//本地请求是否成功；
            if (result.getResult() != null) {//服务器查询返回是否是规范化的内容，是则优先判断返回内容规范正确性
                if (result.getResult().code == 200 || result.getResult().code == 0) {
                    onResult.onSuccess(result.getResult().getData());
                } else {
                    onResult.onFail(result.getResultDes());
                    if (result.getResult().code == 99)
                        onResult.onTokenError("退出登录");
                }
            } else {//未指定返回类型则将返回的内容以String方式返回交由Presenter处理
                onResult.onSuccess(result.getResultDes(), null);
            }
        } else {

                onResult.onTokenError(result.getResultDes());

    }


    public onResult onResult;

    public interface onResult<T> {

        void onSuccess(T result);

        void onFail(String ResultDes);

        void onTokenError(String tip);
    }
}

好了，接下来就是使用啦
哈哈哈哈哈哈哈，也算一行代码搞定了

UrlInfo mUrlInfo = new UrlInfo();
        mUrlInfo.setURL("接口URL");
        //mUrlInfo.setParams("xxx=xxx");//入参方式1
        mUrlInfo.addParams("xxx","xxx");//入参方式2
        mUrlInfo.setContentType("application/json;charset=UTF-8");
        mUrlInfo.setToken("");
        Type type = new TypeToken<Result<ArrayList<taskInfo>>() {
        }.getType();
        new HttpAsyncTask(HttpAsyncTask.HTTP_TYPE_POST, mUrlInfo, new HttpAsyncTask.onResult<ArrayList<taskInfo>>() {
            @Override
            public void onSuccess(ArrayList<taskInfo> result) {

            }

            @Override
            public void onFail(String ResultDes) {

            }
            @Override
            public void onTokenError(String tip) {

            }
        }, type);

对了如果是带页码的数据
还需要做增加一个
Rows.calss

public class Rows<T> {
    T data;//单页数据
    int pageNo = 0;//当前页码
    int pageSize = 0;//当前页条目数
    int records = 0;//总条目数
    int total = 0;//总页数

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public int getPageNo() {
        return pageNo;
    }

    public void setPageNo(int pageNo) {
        this.pageNo = pageNo;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public int getRecords() {
        return records;
    }

    public void setRecords(int records) {
        this.records = records;
    }

    public int getTotal() {
        return total;
    }

    public void setTotal(int total) {
        this.total = total;
    }
}

好了，代码至此就完了，需要说明的是，代码在拷贝过来的过程中，我有删掉一些自定义的内容，原因是懒得一起贴上来，如果拷贝使用过程中有什么报错的，哈哈哈哈，自己排查一下，应该都是容易解决的。逻辑流程还是比较简单的，分享给大家，也是自己记录一下，当然啦，有不足的地方/更好的方式/需要优化的地方也欢迎大家一起探讨一下；
