Error : 404 Resource not found

[ghost]

Hello,

i am trying to Demonstration a sample but i am get always this error { "statusCode : 404" "messeges : resource not found"}

can anybody help me please, the code looks like this: ''use strict';

const request = require('request');

// Replace with your valid subscription key.

'use strict';

const subscriptionKey = '7***';

// You must use the same location in your REST call as you used to get your // subscription keys. For example, if you got your subscription keys from // westus, replace "westcentralus" in the URL below with "westus".

const uriBase = 'https://westcentralus.api.cognitive.microsoft.com/vision/v1.0';

const imageUrl = 'https://upload.wikimedia.org/wikipedia/commons/thumb/a/af/Atomist_quote_from_Democritus.png/338px-Atomist_quote_from_Democritus.png';

// Request parameters. const params = { 'language': 'unk', 'detectOrientation': 'true', };

const options = { uri: uriBase, qs: params, body: '{"url": ' + '"' + imageUrl + '"}', headers: { 'Content-Type': 'application/json', 'Ocp-Apim-Subscription-Key' : subscriptionKey } };

request.post(options, (error, response, body) => { if (error) { console.log('Error: ', error); return; } let jsonResponse = JSON.stringify(JSON.parse(body), null, ' '); console.log('JSON Response\n'); console.log(jsonResponse); });'

I tried your example but with

const uriBase = 'https://westcentralus.api.cognitive.microsoft.com/vision/v2.0/ocr'; instead of const uriBase = 'https://westcentralus.api.cognitive.microsoft.com/vision/v1.0';

and got a different result - message: "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription."

as expected, as I don't have a subscription key. Can you try with this uriBase?

it worked, I have last two questions before you close this issue. Do you have a Sample, which can provide the text in images with bot-builder? and the other question: with which function can I get the Text of Json like a string in this example: I want to get the texts like this: "NOTHING EXISTS"

' "textAngle": 0, "regions": [ { "boundingBox": "21,16,304,451", "lines": [ { "boundingBox": "28,16,288,41", "words": [ { "boundingBox": "28,16,288,41", "text": "NOTHING" } ] }, { "boundingBox": "27,66,283,52", "words": [ { "boundingBox": "27,66,283,52", "text": "EXISTS" } ] },'

No, I am not familiar with this product, just happened to peep into it in an attempt to support you. Please ask this to their support forum.

with which function can I get the Text of Json like a string in this example: I want to get the texts like this: "NOTHING EXISTS"

Here is how you could do it:

cat 1426_1.js

const obj = {
  textAngle: 0,
  regions: [
  {
    boundingBox: "21,16,304,451",
    lines: [
    {
      boundingBox: "28,16,288,41",
      words: [
      {
        boundingBox: "28,16,288,41",
        text: "NOTHING"
      }
      ]
    },
    {
      boundingBox: "27,66,283,52",
      words: [
      {
        boundingBox: "27,66,283,52",
        text: "EXISTS"
      }
      ]
    }
    ]
  }
  ]
}

let buf = ''
obj.regions.forEach((a, b, c) => {
  a.lines.forEach((p, q, r) => {
    p.words.forEach((x, y, z) => {
      buf += ` ${x.text}`
    })
  })
})

console.log(buf)

node 1426_1.js

NOTHING EXISTS #

Hope this helps!

thanks for your response, i tried it with my code but why i am getting this error in your opinion ? the error is cannot read property 'forEach ' of undefined app.js 41:13 obj.regions.forEach(a,b,c) => { this is my code looks like: ''use strict';

const request = require('request');

// Replace with your valid subscription key. const subscriptionKey = '02***'; // You must use the same location in your REST call as you used to get your // subscription keys. For example, if you got your subscription keys from // westus, replace "westcentralus" in the URL below with "westus". const uriBase = 'https://westcentralus.api.cognitive.microsoft.com/vision/v2.0/ocr';

const imageUrl = 'https://i.pinimg.com/originals/c3/cc/b2/c3ccb2dee31874b2ba8c9e0a35d4f1b6.jpg';

// Request parameters. const params = { 'language': 'unk', 'detectOrientation': 'true', };

const options = { uri: uriBase, qs: params, body: '{"url": ' + '"' + imageUrl + '"}', headers: { 'Content-Type': 'application/json', 'Ocp-Apim-Subscription-Key' : subscriptionKey } };

request.post(options, (error, response, body) => { if (error) { console.log('Error: ', error); return; }

const obj = JSON.stringify(JSON.parse(body), null, ' ');

//------------ get the texts from json as string let buf = '' obj.regions.forEach((a, b, c) => { a.lines.forEach((p, q, r) => { p.words.forEach((x, y, z) => { buf += ${x.text} }) }) })

console.log(buf) //------------- console.log('JSON Response\n');

});'

you will need to perform nullchecks. That is, for each object, make sure it is not null before accessing its members. So the snippet will change to:

if(obj && obj.regions) {
  obj.regions.forEach((a, b, c) => {
    if(a && a.lines) {
      a.lines.forEach((p, q, r) => {
        if(p && p.words) {
          p.words.forEach((x, y, z) => {
            buf += ` ${x.text}`
          })
        }
      })
    }
  })
}
