# Отчет по лабораторной работе №3
|
||||
|
||||
Выполнил студент гр. ИСЭбд-41 Мытарин Е.С.
|
||||
|
||||
## REST API, Gateway и синхронный обмен между микросервисами
|
||||
|
||||
## Создание микросервисов
|
||||
|
||||
1. С помощью команды `dotnet new web -n worker-2` в терминале создал первый микросервис
|
||||
2. Добавил решение командой `dotnet new sln`
|
||||
3. Связал решение и проект командой `dotnet sln worker-2.sln add worker-2.csproj`
|
||||
4. Повторил действие для второго микросервиса
|
||||
5. Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`
|
||||
|
||||
Скриншоты протестированных микросервисов:
|
||||
|
||||
|
||||
|
||||
## Реализация синхронного обмена
|
||||
|
||||
Реализовал код, который вызывает сихронно данные из соседнего микросервиса.
|
||||
|
||||
```cs
|
||||
//worker-2
|
||||
app.MapGet("/Requests/", 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
|
||||
|
||||
Добавил nginx.conf:
|
||||
|
||||
```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;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Результат, после выполнения команды `docker-compose up`:
|
||||
|
||||
Docker:
|
||||
|
||||
|
||||
|
||||
index.html на gateway-1:
