我们有一个网站,提供用于访问其存储数据的REST API。
我们想从Microsoft Azure中的WEB APP Service访问这些REST API。 这可能吗?

您可以简单地使用HttpClient并调用您的Web api。她的代码是相同的:
P.S:-我正在为您提供一个控制台应用程序示例,但您也可以使用网络应用程序来做同样的事情
using System;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
namespace HttpClientSample
{
public class Product
{
public string Id { get; set; }
public string Name { get; set; }
public decimal Price { get; set; }
public string Category { get; set; }
}
class Program
{
static HttpClient client = new HttpClient();
static void ShowProduct(Product product)
{
Console.WriteLine($"Name: {product.Name}\tPrice: " +
$"{product.Price}\tCategory: {product.Category}");
}
static async Task<Uri> CreateProductAsync(Product product)
{
HttpResponseMessage response = await client.PostAsJsonAsync(
"api/products", product);
response.EnsureSuccessStatusCode();
// return URI of the created resource.
return response.Headers.Location;
}
static async Task<Product> GetProductAsync(string path)
{
Product product = null;
HttpResponseMessage response = await client.GetAsync(path);
if (response.IsSuccessStatusCode)
{
product = await response.Content.ReadAsAsync<Product>();
}
return product;
}
static async Task<Product> UpdateProductAsync(Product product)
{
HttpResponseMessage response = await client.PutAsJsonAsync(
$"api/products/{product.Id}", product);
response.EnsureSuccessStatusCode();
// Deserialize the updated product from the response body.
product = await response.Content.ReadAsAsync<Product>();
return product;
}
static async Task<HttpStatusCode> DeleteProductAsync(string id)
{
HttpResponseMessage response = await client.DeleteAsync(
$"api/products/{id}");
return response.StatusCode;
}
static void Main()
{
RunAsync().GetAwaiter().GetResult();
}
static async Task RunAsync()
{
// Update port # in the following line.
client.BaseAddress = new Uri("http://localhost:64195/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
try
{
// Create a new product
Product product = new Product
{
Name = "Gizmo",
Price = 100,
Category = "Widgets"
};
var url = await CreateProductAsync(product);
Console.WriteLine($"Created at {url}");
// Get the product
product = await GetProductAsync(url.PathAndQuery);
ShowProduct(product);
// Update the product
Console.WriteLine("Updating price...");
product.Price = 80;
await UpdateProductAsync(product);
// Get the updated product
product = await GetProductAsync(url.PathAndQuery);
ShowProduct(product);
// Delete the product
var statusCode = await DeleteProductAsync(product.Id);
Console.WriteLine($"Deleted (HTTP Status = {(int)statusCode})");
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
Console.ReadLine();
}
}
}
