# Отчёт по лабораторной работе №3
Выполнила: студентка группы ИСЭбд-41 Горбылева Антонина Игоревна
Используемые сущности: Автомобили - Car, марка автомобиля - Marka, модель - model, номер - number
## REST API, Gateway и синхронный обмен между микросервисами
## Создание микросервисов
Команда `dotnet new web -n worker-1` создает в терминале микросервис worker-1.
Команда `dotnet new sln`для создания решения для проекта.
Команда `dotnet sln worker-1.sln add worker-1.csproj`связывает созданное решение с проектом.
Аналогично, создаем второй микросервис и добавляем оба проекта в единое решение.
Команда `dotnet run` для запуска проекта.
Скриншоты API приложений:
![](picture/sworker-1.png)
![](picture/sworker-2.png)
## Реализация синхронного обмена
Реализован механизм синхронного обмена сообщениями между микросервисами.
```cs
app.MapGet("/Company/", async () =>
{
var httpClient = new HttpClient();
var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
return secondWorkerResponse.ToArray();
})
.WithName("GetRequests")
.WithOpenApi();
```
## Реализация gateway при помощи nginx
Шлюз на основе прозрачного прокси-сервера nginx
```conf
server {
listen 8080;
listen [::]:8080;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location /worker-1/ {
proxy_pass http://worker-1:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix /worker-1;
}
location /worker-2/ {
proxy_pass http://worker-2:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix /worker-2;
}
}
```
Результаты, после вызова команды `docker-compose up`:

# Отчёт по лабораторной работе №3
Выполнила: студентка гр. ИСЭбд-41 Никифорова Татьяна Сергеевна.
## REST API, Gateway и синхронный обмен между микросервисами
## Создание микросервисов
Использовала команду `dotnet new web -n worker-1` в терминале для создания моего первого микросервиса.
Далее, с помощью команды `dotnet new sln`, создала решение для проекта. Затем использовала команду `dotnet sln worker-1.sln add worker-1.csproj`, чтобы связать созданное решение с проектом.
Повторила те же действия для второго микросервиса, добавила оба проекта в единое решение.
Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`".
Скриншоты API приложений:

## Реализация синхронного обмена
Реализовала механизм синхронного обмена сообщениями между микросервисами.
```cs
app.MapGet("/Authors/", async () =>
{
var httpClient = new HttpClient();
var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
return secondWorkerResponse.ToArray();
})
.WithName("GetRequests")
.WithOpenApi();
```
## Реализация gateway при помощи nginx
Реализовала шлюз на основе прозрачного прокси-сервера nginx.
```conf
server {
listen 8080;
listen [::]:8080;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location /worker-1/ {
proxy_pass http://worker-1:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix /worker-1;
}
location /worker-2/ {
proxy_pass http://worker-2:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix /worker-2;
}
}
```
Результаты, после вызова команды `docker-compose up`:
