Azure Functions 脚本编译失败

Question

我正在尝试使用 Docker 创建一个 Azure 函数。当我使用 func new 创建函数时，它工作正常，当我转到 http://localhost:8182/api/HttpTriggerCSharp?name=John 时，我收到消息

Hello, John

现在我正在尝试运行同一个项目，但我更改了代码。之前的代码是这样的：

#r "Newtonsoft.Json"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;

public static IActionResult Run(HttpRequest req, TraceWriter log)
{
log.Info("C# HTTP trigger function processed a request.");

string name = req.Query["name"];

string requestBody = new StreamReader(req.Body).ReadToEnd();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;

return name != null
    ? (ActionResult)new OkObjectResult($"Hello, {name}")
    : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}

现在这是我的新代码：

#r "Newtonsoft.Json"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;

public static IActionResult Run(HttpRequest req, TraceWriter log)
{
 log.Info("C# HTTP trigger function processed a request.");

 // Parsing query parameters
 string name = req.GetQueryNameValuePairs()
 .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
 .Value;
 log.Info("name = " + name);

 string numberOfTerms = req.GetQueryNameValuePairs()
 .FirstOrDefault(q => string.Compare(q.Key, "numberOfTerms", true) == 0)
 .Value;
 log.Info("name = " + numberOfTerms);

 // Validating the parameters received
 if (string.IsNullOrWhiteSpace(name) || string.IsNullOrWhiteSpace(numberOfTerms))
 {
  var errorResponse = req.CreateResponse(HttpStatusCode.BadRequest, 
                                       "Please pass a name and the number of digits on the query string."); 
  return errorResponse;
 }

 int termsToShow;
 try
 {
   termsToShow = Int32.Parse(numberOfTerms);
 }
  catch (FormatException e)
 {
  var errorResponse = req.CreateResponse(HttpStatusCode.BadRequest, 
                                       "The numberOfTerms parameter must be an integer!"); 
  return errorResponse;
 }

 if (termsToShow < 0 || termsToShow > 100) {
   var errorResponse = req.CreateResponse(HttpStatusCode.BadRequest, 
                                       "Please pass a numberOfTerms parameter between 0 and 100."); 
  return errorResponse;
 }

 // Building the response
 string incompleteResponse = "Hello, " + name + ", you requested the first " + numberOfTerms + " terms of the Fibonacci series. Here they are: ";
 string completeResponse = GenerateFibonacciTerms(incompleteResponse, termsToShow);
 var response = req.CreateResponse(HttpStatusCode.OK, completeResponse); 

 // Returning the HTTP response with the string we created
 log.Info("response = " + response);
 return response;
}

public static string GenerateFibonacciTerms(string incompleteResponse, int termsToShow)
{    
    int a = 0;
    int b = 1;
    string temporalString = "";
    
    for (int i = 0; i < termsToShow; i++)
    {
        int temp = a;
        a = b;
        b = temp + b;
        temporalString = temporalString + temp.ToString() + " ";
    }

 string result = incompleteResponse + temporalString + "- That's it, have an awesome day!";
 return result;    
}

我构建容器，然后运行它并收到此消息：

我已经用 VS Code 检查了我的代码（我是在 Sublime Text 中检查的，所以我没有进行代码检查），它发现的所有问题都是同一个错误：

我的代码到处都是 "errors"：

我该如何解决这个问题？

Answer 1

您使用的是v2功能核心工具（基于.net core），而您更改的代码是针对v1（.net framework）的。

所以你有两个选择：

卸载 v2 并使用功能核心工具 v1。
修改您的代码以使其在 v2 运行时中运行。

这里是代码供你参考。 GenerateFibonacciTerms方法不需要改变。

log.Info("C# HTTP trigger function processed a request.");

// Parsing query parameters
string name = req.Query["name"];
log.Info("name = " + name);

string numberOfTerms = req.Query["numberOfTerms"];
log.Info("numberOfTerms = " + numberOfTerms);

// Validating the parameters received
if (string.IsNullOrWhiteSpace(name) || string.IsNullOrWhiteSpace(numberOfTerms))
{
    return new BadRequestObjectResult("Please pass a name and the number of digits on the query string."); 
}

int termsToShow;
try
{
     termsToShow = Int32.Parse(numberOfTerms);
}
 catch (FormatException e)
{
    return new BadRequestObjectResult("The numberOfTerms parameter must be an integer!"); 
}

if (termsToShow < 0 || termsToShow > 100) {
     return new BadRequestObjectResult("Please pass a numberOfTerms parameter between 0 and 100."); 
}

// Building the response
string incompleteResponse = "Hello, " + name + ", you requested the first " + numberOfTerms + " terms of the Fibonacci series. Here they are: ";
string completeResponse = GenerateFibonacciTerms(incompleteResponse, termsToShow);
var response = new OkObjectResult(completeResponse); 

// Returning the HTTP response with the string we created
log.Info("response = " + response);
return response;
