使用Azure Function处理文件 [英] Process a file using Azure Function

问题描述

我想处理一个输入文件，并将其输出到ex的某个位置. FTP或Azure存储.我正在尝试将Azure函数与SaasFile输入/输出一起使用.我遇到以下错误:

I would like to process an input file and output it to some location for ex. FTP or Azure storage. I am trying to use Azure Function with SaasFile input/output. I am getting below error:

2016-07-14T00:44:53 Welcome, you are now connected to log-streaming service. 2016-07-14T00:45:00.580 Script for function 'HttpTriggerCSharp1' changed.

这是我的功能签名:

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, string output, TraceWriter log)

绑定:

{
  "bindings": [
    {
      "authLevel": "function",
      "name": "req",
      "type": "httpTrigger",
      "direction": "in"
    },
    {
      "name": "res",
      "type": "http",
      "direction": "out"
    },
    {
      "type": "apiHubFile",
      "name": "output",
      "path": "path/{file}",
      "connection": "ftp_FTP",
      "direction": "out"
    }
  ],
  "disabled": false
}

我认为我在运行"签名中缺少某些内容.我在 Azure文档上找不到它.

I think I am missing something in Run signature. I couldn't find it on Azure documentation.

我需要帮助弄清楚如何使用FTP和Azure存储进行处理.谢谢你的帮助.

I need help figure out how to process using FTP and Azure Storage. Thanks for your help.

推荐答案

您实际上不需要http触发器. 以下是一个示例，该示例监视文件夹(输入cs)在保管箱中是否有新文件，并将该文件复制到googledrive中的文件夹(输出cs):

You don't really need a http trigger for this. Here is an example which watches a folder(input-cs) for new files in dropbox and copies the file to a folder (output-cs) in googledrive:

using System;

public static void Run(string input, out string output, TraceWriter log)
{
    output = input;
}

绑定:

{

 "bindings": [
    {
      "type": "apiHubFileTrigger",
      "name": "input",
      "direction": "in",
      "path": "input-cs/{name}",
      "connection": "dropbox_DROPBOX"
    },
    {
      "type": "apiHubFile",
      "name": "output",
      "direction": "out",
      "path": "output-cs/{name}",
      "connection": "googledrive_GOOGLEDRIVE"
    }
  ],
  "disabled": false
}
