javascript - 无法验证google cloud vision API。 如何对其进行身份验证以进一步使用它(Not able to autheticate google cloud vision api . How to autheticate it to use it further)

Question

My Code looks like this :-

(我的代码如下所示：)

var vision = require('@google-cloud/vision');
handleSubmit = () =>{ 
        console.log("encoded string submitted=",this.state.files);            
        this.useVisionCloud();
    }

    useVisionCloud = () =>{

            const client = new vision.ImageAnnotatorClient();
            const request_body = {
                "requests": [
                  {
                    "image": {
                      "content": this.state.files
                    },
                    "features": [
                      {
                        "type": "TEXT_DETECTION"
                      }
                    ]
                  }
                ]
              };
              client.textDetection(request_body).then(response => {
                    console.log("text got=",response);                    
                  // doThingsWith(response);
                })
                .catch(err => {
                    console.log("error got=",err);   
                });
    }

1. I already tried setting environment variable but didn't work .

   (我已经尝试设置环境变量，但是没有用。)

2. I have also created service account and downloaded the file.json but dont know how to use it for authentication

   (我还创建了服务帐户并下载了file.json， 但不知道如何使用它进行身份验证)

im getting the following error :-

(即时通讯收到以下错误：)

Uncaught Error: {"clientConfig":{},"port":443,"servicePath":"vision.googleapis.com","scopes":["https://www.googleapis.com/auth/cloud-platform","https://www.googleapis.com/auth/cloud-vision"]}You need to pass auth instance to use gRPC-fallback client in browser. Use OAuth2Client from google-auth-library.

on triggering a post request to Google API .

(触发对Google API的发布请求。)

Final Query is :- I am not able to understand how to authenticate API so that i can further use it to detect text in my images

(最终查询是：-我无法理解如何对API进行身份验证，以便我可以进一步使用它来检测图像中的文本)
