Azure Function无法用于参数化的API [英] Azure Function not working for parameterized API
问题描述
我从下面的线程中找到了解决问题的方法
I followed a solution to my problem from this below thread
https://stackoverflow.com/questions/62596741/azure-function-not-working-cannot-declare-namespace-in-script-code
我在本地创建了一个代码,然后在线发布了该代码-它在两个版本上均有效-本地&Azure功能.
I created a code locally and published it online - it was working on both - local & Azure function.
下面的代码段都可以使用-本地&Azure功能.请注意,文件名是硬编码的.
Below code snippet isworking on both - local & Azure function. Notice that filename is hardcoded.
using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using Azure.Storage.Blobs;
namespace FunctionApp1
{
public static class Function1
{
[FunctionName("Function1")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
string filename = "success.png";
string storageconnstring = "**********";
BlobServiceClient blobServiceClient = new BlobServiceClient(storageconnstring);
BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient("demo");
BlobClient blobClient = containerClient.GetBlobClient(filename);
var blobUri = blobClient.Uri;
BlobContainerClient targetContainerClient = blobServiceClient.GetBlobContainerClient("demo-copy");//This is the container where we want to copy the blob
BlobClient targetBlobClient = targetContainerClient.GetBlobClient(filename);
await targetBlobClient.StartCopyFromUriAsync(blobUri);
return new OkObjectResult(responseMessage);
}
}
}
现在此代码仅在本地运行-我所做的唯一更改是现在您可以传递文件名了.我在做什么错了?
Now this code is working only locally - the ONLY change I did was that now you can pass the filename. What I am doing wrong?

{
log.LogInformation("C# HTTP trigger function processed a request.");
string filename = req.Query["filename"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
filename = filename ?? data?.filename;
string responseMessage = string.IsNullOrEmpty(filename)
? "This HTTP triggered function executed successfully. Pass a file name in the query string or in the request body for initiating a temporary copy"
: $"This HTTP triggered function executed successfully.";
string storageconnstring = "DefaultEndpointsProtocol=https;AccountName=mainices;AccountKey=lrlWVXi9tWDfkjv6XMcMgylPG2fU78nOcK3AwJkRJTBKDQ4FdxJkieYiGBhfFTYULl+IHey0OJASpkHlg25Eaw==;EndpointSuffix=core.windows.net";
BlobServiceClient blobServiceClient = new BlobServiceClient(storageconnstring);
BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient("demo");
BlobClient blobClient = containerClient.GetBlobClient(filename);
var blobUri = blobClient.Uri;
BlobContainerClient targetContainerClient = blobServiceClient.GetBlobContainerClient("demo-copy");//This is the container where we want to copy the blob
BlobClient targetBlobClient = targetContainerClient.GetBlobClient(filename);
await targetBlobClient.StartCopyFromUriAsync(blobUri);
return new OkObjectResult(targetBlobClient.Uri);
}
}
}
推荐答案
在您将自动化级别定义为函数时,它需要一个函数键:
As you defined the autorization level as functions, it is expecting a function key:
[HttpTrigger(AuthorizationLevel.Function
您需要将其添加到您的查询字符串中:
you'll need to add it to your querystring:
https://< APP_NAME> .azurewebsites.net/api/< FUNCTION_NAME>?code =< API_KEY>
https://<APP_NAME>.azurewebsites.net/api/<FUNCTION_NAME>?code=<API_KEY>
PS: do not forget to pass the filename parameter too
