问题描述

我正在尝试开发C#Google Vision API函数.

I am trying to develop C# Google Vision API function.

该代码应编译为dll，并且应运行以执行以下步骤.

the code is supposed to compile into dll and it should run to do the following steps.

从图像路径获取图像.
将图像发送到Google视觉api
调用文档文本检测功能
获取返回值(文本字符串值)
完成

当我运行dll时，它一直给我抛出异常异常错误.我假设问题出在Google凭证上，但不确定...

When I run the dll, However, it keeps giving me an throw exception error. I am assuming that the problem is on the google credential but not sure...

有人可以帮我这个忙吗?我什至不知道var凭据= GoogleCredential.FromFile(Credential_Path);是调用json文件的正确方法...

Could somebody help me out with this? I don't even know that the var credential = GoogleCredential.FromFile(Credential_Path); would be the right way to call the json file...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Google.Cloud.Vision.V1;
using Google.Apis.Auth.OAuth2;
using Image = Google.Cloud.Vision.V1.Image;


namespace DLL_TEST_NetFramework4._6._1version
{
    public class Class1
    {
        public string doc_text_dection(string GVA_File_Path, string Credential_Path)
        {
            var credential = GoogleCredential.FromFile(Credential_Path);
            //Load the image file into memory
            var image = Image.FromFile(GVA_File_Path);

            // Instantiates a client
            ImageAnnotatorClient client = ImageAnnotatorClient.Create();

            TextAnnotation text = client.DetectDocumentText(image);
            //Console.WriteLine($"Text: {text.Text}");

            return $"Text: {text.Text}";
            //return "test image...";
        }
    }
}
