[英]Debugging Http Trigger Azure Function VS 2017
I have Visual Studio 2017 15.3 and have installed the Azure Development workload installed. 我拥有Visual Studio 2017 15.3,并且已安装Azure开发工作负载。
I created a blank HttpTrigger
according to this article: 我根据这篇文章创建了一个空白的HttpTrigger

I can debug successfully if I use Name
as parameter query string. 如果使用Name
作为参数查询字符串,则可以成功调试。
However, If I use Postman to create this Post request: 但是,如果我使用邮递员创建此Post请求:
{
"name": "Azure"
}
I get the following error: 我收到以下错误:
"mscorlib: Exception while executing function: HttpTrigger . Anonymously Hosted DynamicMethods Assembly: 'Newtonsoft.Json.Linq.JObject' doe s not contain a definition for 'name'." “ mscorlib:执行函数:HttpTrigger时发生异常。匿名托管的DynamicMethods程序集:'Newtonsoft.Json.Linq.JObject'doe不包含'name'的定义。”
Here is my code for the function app in Visual Studio 2017: 这是我在Visual Studio 2017中的功能应用程序的代码:
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Azure.WebJobs.Host;
namespace VS2017TestFunctionApp
{
public static class HttpTrigger
{
[FunctionName("HttpTrigger")]
public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log)
{
log.Info("C# HTTP trigger function processed a request.");
// parse query parameter
string name = req.GetQueryNameValuePairs()
.FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
.Value;
// Get request body
dynamic data = await req.Content.ReadAsAsync<object>();
// Set name to query string or body data
name = name ?? data?.name;
return name == null
? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
: req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
}
}
}
Also, if I copy the exact same code within the Run function and use the same test post in a function app via the Azure Portal it all works fine. 另外,如果我在“运行”函数中复制完全相同的代码,并通过Azure门户在函数应用程序中使用相同的测试文章,则一切正常。
I create a Azure function app with your code and send a request using Postman, which works fine on my side. 我用您的代码创建了一个Azure函数应用程序,并使用Postman发送了一个请求,这对我来说很好。
Request and Response 请求和回应
Request body: 要求正文:
The breakpoint at getting request body can be hit as expected 可以按预期命中获取请求正文的断点
edit: 编辑:
I can extract name
from data
without any error. 我可以从data
提取name
,而不会出现任何错误。
