我们在开发中,网络请求经常会遇到各种错误码的判断。比如下面这样:
先不说正常的错误码,就项目中的这些码,不可能我们每次都自己去判一遍吧,这样也太麻烦了。刚好实习期间项目中有很多需要的地方,于是写了个简单的小工具。
代码很简单,并没有太多优化,我们在使用时可以按照自己的想法,自由定制,再多的设计模式都只是为了更好的使用,所以不用太过在意,如果考虑优化,那么可以进行更好的封装改造,这里我只是简单给一个解决的思想。
流程大概是这样的:
首先,创建自己的数据Bean类,GsonGormat一键生成,然后继承于BaseDataBean,利用泛型自由实现我们需求。成功返回我们需要的bean对象,否则弹出失败dialog。
使用时
String json=""; //请求成功与否: boolean mode = ErrorDialogFragmentUtils .Builder() .setContext(getContext()) .setMessage("成功响应") //报错时将直接赋予错误码 .setManager(getFragmentManager()) .setIlistener(new IDialogListener() { @Override public void onPositiveClick() { //确定按钮 } @Override public void onNegativeClick() { //取消按钮 } }) .setDialogDimss(() -> { //dialog关闭监听 }) .setiDataCode((code, res) -> { //接收网络码 }) .build() .setJson(json, GLoginBean.class, gLoginBean -> { //如果成功,这里拿到你的bean对象 });
自由更改 ErrorDialogFragmentUtils 中的代码,比如错误码及一些特定错误码的处理逻辑。在这里,因为我们后端并没有对有些特定码有处理逻辑,所以我暂时空着,但为了备用,留下了错误码的出口,可以调用 setIDataCode(),实现相应的接口即可拿到失败码,更多的特定业务方法,可以仿照我的写法自由添加或者更改。
这里对一些处理逻辑,谈谈我的看法:
看一下代码,就很简单吧,下面开始上代码:
工具类,自由定义

// private static SparseArray codes;
/*static {
// 自定义相应的错误码,或者后端提供的话,忽略这里即可
codes = new SparseArray<>();
codes.put(-1, "系统繁忙,稍后重试");
codes.put(0, "操作成功");
codes.put(100, "验签错误,操作失败");
codes.put(200, "参数错误,操作失败");
codes.put(210, "用户名与密码不匹配,请重试");
codes.put(211, "登录验证码错误,请重试");
codes.put(900, "token失效,及时刷新");
codes.put(901, "token失效,重新登录");
codes.put(500, "逻辑异常");
