該功能由 [`Requests`](https://github.com/hsiafan/requests) 拓展而來
> Java版 Python Requests。語法簡潔，鏈式調用，Cookies自動管理......目前拓展了請求重試。

# 簡單示例
```
// 方式1
Map<String, Object> params = Maps.newHashMap();
params.put("k1", "v1");
params.put("k2", "v2");
String resp1 = Requests.get(url).params(params).send().readToText(); // params
String resp2 = Requests.post(url).body(params).send().readToText(); // body
String resp3 = Requests.post(url).forms(params).send().readToText(); // forms
// 方式2
String resp = Requests.post(url)
.params(
Parameter.of("k1", "v1"),
Parameter.of("k2", "v2"))
.send()
.readToText();
```

# 重試示例
默認重試
```
@Test
public void http1() {
// 構造請求
RequestBuilder req = Requests.post(url).params(Parameter.of("k1", "v1"));
// 請求重試
RawResponse response = RequestsHelper.retry(req);
// 獲取結果
TestRetryResponse result = response.readToJson(TestRetryResponse.class);
}
```
自定義重試
```
@Test
public void http2() {
// 構造請求
RequestBuilder builder = HttpHelper.post(url).params(Parameter.of("k1", "v1"));
// 構造重試（見下章）
Retryer<RawResponse> retryer = RetryerBuilder.<RawResponse>newBuilder().build();
// 請求
RawResponse response = HttpHelper.retry(builder, retryer);
// 獲取結果
TestRetryResponse result = response.readToJson(TestRetryResponse.class);
}
```
# 驗證結果
這里默認重試了3次，每次等1秒
```

請求成功返回：
```
{
"code":0,
"msg":"操作成功",
"data":{
},
"success":true
}
```
重試失敗返回：
```
{
"code": 2000,
