从我的结束后再现，这是工作正常，当我按照下面的过程.我已经创建了2 Blob触发函数，其中一个是转换PDF到txt文件，另一个是读取txt文件，做所需的操作，然后保存到另一个容器.
pdf触发一个函数，该函数提取文本并将其保存为容器中的txt

• Function1.cs -阅读pdf文件并将其保存为容器中的文本文件 *

using System.IO;
using Microsoft.Azure.WebJobs;
using Microsoft.Extensions.Logging;
using iTextSharp.text.pdf;
using iTextSharp.text.pdf.parser;

namespace FunctionApp5
{
    public class Function1
    {
        [FunctionName("Function1")]
        public void Run([BlobTrigger("pdfcontainer/{name}", Connection = "constr")]Stream myBlob, string name,
            [Blob("textcontainer/1.txt", FileAccess.Write, Connection = "constr")] Stream outputBlob,ILogger log)
        {
            log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
            PdfReader reader = new PdfReader(myBlob);
            int intPageNum = reader.NumberOfPages;
            string[] words;
            string line;
            string text;

            for (int i = 1; i <= intPageNum; i++)
            {
                text = PdfTextExtractor.GetTextFromPage(reader, i, new LocationTextExtractionStrategy());
                using (var writer = new StreamWriter(outputBlob))
                {
                    writer.Write(text);
                }
            }
        }
    }
}

• 结果：*

提取的文本触发一个函数，该函数对结果进行优化并在容器中写入第三个文件

• Function2.cs -阅读上传的文本文件并进行一些操作，然后将其保存到另一个容器 *

using System.IO;
using System.Text;
using Microsoft.Azure.WebJobs;
using Microsoft.Extensions.Logging;

namespace FunctionApp5
{
    public class Function2
    {
        [FunctionName("Function2")]
        public void Run([BlobTrigger("textcontainer/{name}", Connection = "constr")] Stream myBlob, string name,
            [Blob("finalcontainer/1.txt", FileAccess.Write, Connection = "constr")] Stream outputBlob, ILogger log)
        {
            log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");

            string finalValue;

            using (var reader = new StreamReader(myBlob, Encoding.UTF8))
            {
                finalValue = reader.ReadLine();
            }

            using (var writer = new StreamWriter(outputBlob))
            {
                writer.Write(finalValue.ToUpper());
            }
        }
    }
}

• 结果：*
