Как использовать

Помогает разработчикам Caffeine получать данные WeatherAPI.com из серверного контейнера на Motoko. Подходит для текущей погоды, прогнозов, астрономических данных и поиска местоположений.

  1. Укажите город, координаты или другой поддерживаемый способ определения места.
  2. Выберите нужные данные и период, сопоставив их с тарифом WeatherAPI.com.
  3. Попросите подключить готовый клиент и определить поведение при отсутствующих данных и ошибках.

Условия работы

  • Для погодных запросов Caffeine обязателен пакет weatherapi-client версии ~0.2.0; самостоятельные HTTP-запросы к WeatherAPI.com запрещены.
  • Нужен ключ WeatherAPI.com: хранить его следует в устойчивой переменной, изменяемой только администратором. Ключ нельзя встраивать в код или записывать URL запроса в журнал.
  • История, будущая погода, морские данные и прогноз на 14 дней требуют платного тарифа; поля ответа могут отсутствовать.
  • Нужно сохранять нереплицируемые запросы по умолчанию. Репликация допустима только с преобразованием ответа, удаляющим изменчивые поля.

Пример запроса после установки

Подключи к моему приложению Caffeine текущую температуру в Цюрихе и прогноз максимальных температур на три дня с обработкой отсутствующих данных.

Пример составлен по инструкции автора; результат запуска не проверялся.

Основание: инструкция закреплённой версии

Для установки

Node.js, npm и Git для команды выше. Подключения и инструменты для работы скилла настраиваются отдельно.

Совместимые агенты

Совместимость указана для инструкций. Запуск в каждом приложении не тестировался; для веб-чата способ подключения может отличаться.

  MANDATORY recipe for every Caffeine build that reads weather data from a
  canister. The supported path is the `weatherapi-client` mops package
  (WeatherAPI.com) over outbound HTTPS, authenticated with a query-string API
  key. Hand-rolling `ic.http_request` calls to `api.weatherapi.com` is a
  FORBIDDEN anti-pattern — it bypasses the non-replicated-outcall safeguard
  (WeatherAPI bodies carry per-request clocks and fail consensus), the generated
  JSON decoding, and the API-key handling. Load this skill whenever the user,
  spec, or any prior task mentions weather, forecast, temperature, humidity,
  wind, rain, snow, conditions, sunrise, sunset, moon phase, astronomy,
  timezone, IP geolocation, marine or tide forecasts, or location autocomplete —
  and BEFORE writing any code that touches a weather endpoint.

# Weather data with `weatherapi-client`

Motoko bindings for [WeatherAPI.com](https://www.weatherapi.com/), generated
from its OpenAPI spec. All nine operations live in a single module,
**`Apis/APIsApi`**, and all nine are read-only `GET`s.

# Backend

A canister that reads the current temperature and a three-day maximum series.
Non-replicated is the default, so you only supply the key:

```motoko filepath=src/backend/main.mo
import { realtimeWeather; forecastWeather } "mo:weatherapi-client/Apis/APIsApi";
import { type Config; defaultConfig } "mo:weatherapi-client/Config";
import Array "mo:core/Array"; // in scope so `days.map(…)` dot notation resolves

actor {
  // The key is a query-string credential. Hold it in a stable variable set by
  // an admin call; never hard-code it in source.
  func config(apiKey : Text) : Config = { defaultConfig with auth = ?#apiKey apiKey };

  // `q` is any WeatherAPI location query: "Zurich", "47.37,8.55", a postcode,
  // an IATA code, or "auto:ip".
  public func currentTempC(apiKey : Text, q : Text) : async ?Float {
    let res = await* realtimeWeather(config apiKey, q, "");
    do ? { res.current!.temp_c! };
  };

  // Daily maxima for the next three days.
  public func maxTempsC(apiKey : Text, q : Text) : async [?Float] {
    let res = await* forecastWeather(config apiKey, q, #_3_, "", 0, 0, "", "no", "no", 0);
    let ?forecast = res.forecast else return [];
    let ?days = forecast.forecastday else return [];
    days.map(func(d) = do ? { d.day!.maxtemp_c! });
  };
}
```

## The nine operations

| Function | Endpoint | Returns |
|---|---|---|
| `realtimeWeather(cfg, q, lang)` | `/current.json` | `RealtimeWeather200Response` |
| `forecastWeather(cfg, q, days, dt, unixdt, hour, lang, alerts, aqi, tp)` | `/forecast.json` | `ForecastWeather200Response` |
| `historyWeather(cfg, q, dt, unixdt, endDt, unixendDt, hour, lang)` | `/history.json` | `FutureWeather200Response` |
| `futureWeather(cfg, q, dt, lang)` | `/future.json` | `FutureWeather200Response` |
| `marineWeather(cfg, q, days, dt, unixdt, hour, lang)` | `/marine.json` | `MarineWeather200Response` |
| `astronomy(cfg, q, dt)` | `/astronomy.json` | `Astronomy200Response` |
| `timeZone(cfg, q)` | `/timezone.json` | `Location` |
| `ipLookup(cfg, q)` | `/ip.json` | `Ip` |
| `searchAutocompleteWeather(cfg, q)` | `/search.json` | `[Search]` |

`days` is an enum, not a number: `ForecastWeatherDaysParameter` is `#_1_` … `#_14_`
and `MarineWeatherDaysParameter` is `#_1_` … `#_7_` (the underscores are how the
generator escapes numeric enum values — `#_3_`, not `#_3` or `3`).

## API key setup

1. Sign up at [weatherapi.com](https://www.weatherapi.com/signup.aspx) — the
   free tier covers current weather, 3-day forecast, astronomy, timezone,
   search and IP lookup. History, future, marine and 14-day forecasts need a
   paid plan and return **403** on free keys.
2. Copy the key from the dashboard and pass it as `auth = ?#apiKey key`.
3. The client appends it as `?key=…` (WeatherAPI takes no `Authorization`
   header), so **it appears in the request URL**. Keep it in a stable variable
   written by an admin-only call, and never log the built URL.

## Calls are non-replicated by default

The package ships `is_replicated = ?false` in `defaultConfig`, and that is a
*correctness* requirement here, not just a cost saving. Every response carries
per-request clocks — `Location.localtime` / `localtime_epoch`,
`Current.last_updated` / `last_updated_epoch` — which change second to second. A
*replicated* outcall has every subnet node issue its own request and demands
bit-identical bodies, so those fields would break consensus on most calls while
burning ~13× the cycles. You don't set it yourself; the default is correct.

Override with `is_replicated = ?true` only together with a `transform` that
strips the volatile fields.

## Everything is optional

WeatherAPI marks no response field required, so the generated models are
all-optional: `RealtimeWeather200Response.current : ?Current`,
`Current.temp_c : ?Float`, and so on. Reach through them with a `do ?` block
(`do ? { res.current!.temp_c! }`) rather than nested `switch`es, and decide what
an absent field means for your caller — the API omits fields your plan does not
cover (for example `air_quality` without the `aqi=yes` parameter).

## Empty string and zero mean "omit"

Optional query parameters are dropped when they are `""` or `0`, because
WeatherAPI rejects empty `lang=` and zero-valued numerics. So passing `""` for
`lang`, `dt`, `alerts`, `aqi` and `0` for `unixdt`, `tp` is how you say "not
supplied" — there is no `?Text` parameter to leave `null`.

One consequence worth knowing: **`hour = 0` does not select midnight**, it omits
the `hour` filter entirely and you get the whole day's hourly array. Filter the
returned `hour : ?[ForecastForecastdayInnerHourInner]` yourself if you need
00:00.

## Errors

Non-2xx responses and decode failures `throw Error.reject(…)`. The client is
generated with `diagnostics`, so the message is
`HTTP <status> body[<n>B]=<first 100 chars>: <reason>` — enough to tell a 401
(bad key) from a 403 (endpoint not on your plan) from a 400 (`q` not resolvable)
without extra logging. Catch with `try`/`catch` and surface
`Error.message(err)`.

Проверка и особенности

      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
