RetrofitClient 基于 OKHttp 和 Retrofit 封装了基本的 GET、POST、PUT、DELET 请求和文件上传下载方法，只需三步，快速集成。

1 在 app 或 lib 级别的 build.gradle 文件中添加依赖

compile 'com.jady:retrofitclient:0.2.6'

2 在 MainApplication 中初始化

HttpManager.init(this, UrlConfig.BASE_URL);
HttpManager.getInstance().setOnGetHeadersListener(new HttpManager.OnGetHeadersListener() {
      @Override
      public Map<String, String> getHeaders() {
          Map<String, String> headers = new HashMap<>();
          headers.put("access_token", "1234");
          return headers;
      }
});

init(Context context, String baseUrl)方法用来传项目的基础 url，当然具体的请求也可以动态修改。 另一个是所有请求都需要添加的的请求头，比如accessToken，deviceKey这种。

3 自动义请求回调

参考： 1.ServerCallback 2.CommonCallback

具体封装过程参考我的另一篇文章android 使用 gson 和泛型解析服务器回调的封装。

使用

参考: 1.实例中的 API 类 2.实例中的 BaseRequestFragment 类

GET 请求

API.testGet(new CommonCallback<Feed>() {

     @Override
     public void onSuccess(Feed feed) {
           tvBaseRequestGet.setText(feed.getContent);
     }

     @Override
     public void onFailure(String error_code, String error_message) {

     }
});

不使用baseUrl:

HttpManager.getFullPath(String fullUrl, Map<String, Object> parameters, HttpCallback callback)

POST 请求

API.testPost(name, password, new ServerCallback<ServerCallbackModel<String>, String>() {

    @Override
    public void onSuccess(String accessToken) {
        showToast("accessToken:" + accessToken);
    }

    @Override
    public void onFailure(String error_code, String error_message) {
    }

    /**
    * 对单个请求允许 Toast 显示错误信息
    */
    @Override
    public boolean enableShowToast() {
        return true;
    }
});

不使用baseUrl:

HttpManager.postFullPath(String fullUrl, Map<String, Object> parameters, HttpCallback callback)

post 对象，以 json 传输

HttpManager.postByBody(String url, T body, HttpCallback callback)

PUT 请求

API.testPut(putContent, new ServerCallback<ServerCallbackModel<Object>, Object>() {

    @Override
    public void onSuccess(Object o) {
        showToast("更新成功");
    }

    @Override
    public void onFailure(String error_code, String error_message) {
        showToast("更新失败,请检查 token");
    }
});

DELETE 请求

API.testDelete(1,new ServerCallback<ServerCallbackModel<Object>, Object>() {
    @Override
    public void onSuccess(Object o) {
        showToast("删除成功");
    }

    @Override
    public void onFailure(String error_code, String error_message) {
        showToast("删除失败,请检查 token");
    }
});

文件上传 单文件上传：

HttpManager.uploadFile(String url, String filePath, String fileDes, TransformProgressListener iProgress)

多文件上传：

HttpManager.uploadFiles(String url, List<String> filePathList, TransformProgressListener iProgress)

如果需要临时改变baseUrl，只需要在发送请求之前调用

HttpManager.setTmpBaseUrl("http://192.168.0.127:8080/retrofitclientserver/");
HttpManager.get(UrlConfig.USER_INFO, null, callback);

如果需要临时添加请求头，需要在发送请求前调用：

HttpManager.addTmpHeaders(headers);
HttpManager.get(UrlConfig.USER_INFO, null, callback);

具体使用方法可以参考库中的 demo。
