Calling nft metadat via cloud function

nani · November 6, 2021, 3:02pm

getalltokenIds is working. any idea?

const options = { address: "0xc638f3a8ecd0579f9e3a75693f87adc4c1357ffd", chain: "rinkeby" };
    let NFTs = await Moralis.Web3API.token.getAllTokenIds(options);

Hi @nani

You need to provide an address of NFT

Yomoo · November 6, 2021, 3:13pm

You can use the Moralis.Web3API in cloud functions instead of HTTP requests

nani · November 6, 2021, 3:20pm

thank you @Yomoo. belwo is my cloud function. I would replace httpRequest with Moralis.Web3API, correct?

here is the address of NFT:
https://rinkeby.etherscan.io/tx/0x555e09822fcf31ed3f4f309908e2eca298a8cbd64162d63fa5151d941fc2faa5

Moralis.Cloud.define("getNFT", async (request) => {
  
  const logger = Moralis.Cloud.getLogger()
  
  
  let NFTId = request.params.nftId;
  let hexId = parseInt(NFTId).toString(16);
  let paddedHex = ("0000000000000000000000000000000000000000000000000000000000000000" + hexId).slice(-64)
  logger.info(paddedHex)
  return Moralis.Cloud.httpRequest({url: "https://feciihxhdokr.usemoralis.com/"+ paddedHex + ".json"})
  .then(function(httpResponse){
    return httpResponse.text;
  })
 
})

@Yomoo or @cryptokid, can you please let me know how to solve the above? should i change anything in my code? Let me know if you need more information. thank you

cryptokid · November 6, 2021, 6:07pm

you can try this syntax: NFTOwners beforesave function failing after update

nani · November 6, 2021, 6:42pm

thank you @cryptokid, but I am a bit lost here. How would you replace your function with my cloud function? if there is a good video, please let me know. thank you
my:

Moralis.Cloud.define("getNFT", async (request) => {
  
  const logger = Moralis.Cloud.getLogger()
  
  
  let NFTId = request.params.nftId;
  let hexId = parseInt(NFTId).toString(16);
  let paddedHex = ("0000000000000000000000000000000000000000000000000000000000000000" + hexId).slice(-64)
  logger.info(paddedHex)
  return Moralis.Cloud.httpRequest({url: "https://feciihxhdokr.usemoralis.com/"+ paddedHex + ".json"})
  .then(function(httpResponse){
    return httpResponse.text;
  })
 
})

yours:

Moralis.Cloud.define("get_token_uri",  (request) => {
    let url = "https://ipfs.moralis.io:2053/ipfs/QmdFfRraiNPbJ4PcTJ8AoXe37ixvkAZJ4JZp3tRCc15j3G";
    return Moralis.Cloud.httpRequest({
      "url": url,
      "headers": {
          'method': 'GET',
          'accept': 'application/json'
         }
     }).then(function(httpResponse){
      return httpResponse.data;
    },function(httpResponse){
      logger.info("error");
      logger.info(httpResponse);
    });
   });

I am calling the cloud function in my main.js as follow:

unction fetchNFTMetadata(NFTs) {
    for (let i = 0; i < NFTs.length; i++) {
        let nft = NFTs[i];
        let id = nft.token_id;
        //Call Moralis cloud funciton -> static json file 
        fetch("https://feciihxhdokr.usemoralis.com:2053/server/functions/getNFT?_ApplicationId=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=" + id)
            //.then(res => res.json())
            .then(res => console.log(res))
    }
}

cryptokid · November 6, 2021, 6:45pm

you can combine those 2 functions, you can get the part that computes the url from your function and get the part with Moralis.Cloud.httpRequest from the other function

nani · November 6, 2021, 7:01pm

thank you @cryptokid . i tried something like that but still receiving an error. what am i missing?


Moralis.Cloud.define("get_token_uri",  (request) => {

    for (let i = 0; i < NFTs.length; i++) {
        let nft = NFTs[i];
        let id = nft.token_id;
        let url = "https://ipfs.moralis.io:2053/ipfs/QmdFfRraiNPbJ4PcTJ8AoXe37ixvkAZJ4JZp3tRCc15j3Ghttps://feciihxhdokr.usemoralis.com:2053/server/functions/getNFT?_ApplicationId=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=" + id
    }
    return Moralis.Cloud.httpRequest({
      "url": url,
      "headers": {
          'method': 'GET',
          'accept': 'application/json'
         }
     }).then(function(httpResponse){
      return httpResponse.data;
    },function(httpResponse){
      logger.info("error");
      logger.info(httpResponse);
    });
});

cryptokid · November 6, 2021, 7:11pm

I don’t know what this code was suppose to do, it has a for loop that only initialises url variable, that url variable is initialised with two https strings + id
I wouldn’t expect that code to work.

you can leave that for in your js, and only change the code of you cloud function to use the part that starts with return Moralis.Cloud.httpRequest( in this function.

nani · November 7, 2021, 12:04pm

@cryptokid what would be my url?

serverUrl: 'https://feciihxhdokr.usemoralis.com:2053/server',
    appId: 'ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC'

and this is my cloud function:


Moralis.Cloud.define("getNFT", async (request) => {

    const logger = Moralis.Cloud.getLogger()


    let NFTId = request.params.nftId;
    let hexId = parseInt(NFTId).toString(16);
    let paddedHex = ("0000000000000000000000000000000000000000000000000000000000000000" + hexId).slice(-64)
    logger.info(paddedHex)
        return Moralis.Cloud.httpRequest({
            "url": {"https://feciihxhdokr.usemoralis.com/" + paddedHex + ".json" },
        "headers": {
            'method': 'GET',
            'accept': 'application/json'
            }
        }).then(function(httpResponse){
        return httpResponse.data;
        },function(httpResponse){
        logger.info("error");
        logger.info(httpResponse);
        });
  });

nani · November 7, 2021, 12:05pm

I am getting an error. i think my url is not correct. what am i missing? any idea?

Yomoo · November 7, 2021, 12:14pm

In your logs, there are messages about syntax problems in your code. You have not valid JS code

Yomoo · November 7, 2021, 12:15pm

We don’t understand what does you code do. Please explain

Yomoo · November 7, 2021, 12:16pm

Syntax problem is there:

"url": {"https://feciihxhdokr.usemoralis.com/" + paddedHex + ".json" },

Change it to:

url: `${"https://feciihxhdokr.usemoralis.com/" + paddedHex + ".json"}`,

nani · November 7, 2021, 12:49pm

thank you @Yomoo. i am not receiving any error message and I am receiving the following output:

Response {type: 'cors', url: 'https://feciihxhdokr.usemoralis.com:2053/server/fu…=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=0', redirected: false, status: 200, ok: true, …}body: (...)bodyUsed: falseheaders: Headers {}ok: trueredirected: falsestatus: 200statusText: ""type: "cors"url: "https://feciihxhdokr.usemoralis.com:2053/server/functions/getNFT?_ApplicationId=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=0"[[Prototype]]: Response

I am trying now to parse the result in a JSON format, similar as shown in the tutorial “Ultimate NFT Programming Tutorial -FULL COURSE” if I execute:

.then(res => console.log(res))

it works. as soon as I am executing:

 //.then(res => res.json())
            //.then(res => JSON.parse(res.result))

I am getting an error, empty result. Can you please provide me with a work around? It is in the video in min 110, 111.

cryptokid · November 7, 2021, 12:57pm

what is the code that you use now?

nani · November 7, 2021, 1:04pm

that’s my current code.

Moralis.start({
    serverUrl: 'https://feciihxhdokr.usemoralis.com:2053/server',
    appId: 'ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC'
})



function fetchNFTMetadata(NFTs) {
    for (let i = 0; i < NFTs.length; i++) {
        let nft = NFTs[i];
        let id = nft.token_id;
        //Call Moralis cloud funciton -> static json file 
        fetch("https://feciihxhdokr.usemoralis.com:2053/server/functions/getNFT?_ApplicationId=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=" + id)
            //.then(res => res.json())
            //.then(res => JSON.parse(res.result))
            .then(res => console.log(res))
    }
}


async function initialzeApp() {
    let currentUser = Moralis.User.current();
    if (!currentUser) {
        currentUser = await Moralis.Web3.authenticate();
    }
    //alert("user is signed in" + currentUser.get('ethAddress'));
    //console.log(currentUser.get('ethAddress'));


    const options = { address: "0xc638f3a8ecd0579f9e3a75693f87adc4c1357ffd", chain: "rinkeby" };
    let NFTs = await Moralis.Web3API.token.getAllTokenIds(options);
    console.log("Hello World");
    console.log(NFTs);
    fetchNFTMetadata(NFTs.result);



}


initialzeApp();

cryptokid · November 7, 2021, 1:09pm

Wouldn’t be easier for use something like
x = await Moralis.Cloud.run(“getFFT”, {nftId : “10”})

nani · November 14, 2021, 1:52pm

@cryptokid, following up on the above. i am getting currently below output by using .then(res => console.log(res)):

Response {type: 'cors', url: 'https://feciihxhdokr.usemoralis.com:2053/server/fu…=ePc0HyzXQdJ3ytVt8J4zhNDWS0WCFSANX6z87xIC&nftId=0', redirected: false, status: 200, ok: true, …}

[[Prototype]]: Response

now, I would like to parse the body. i tried the below, but i am getting always empty results back. any idea how to fix? let me know if you need further information:

            //.then(res => res.json())
            //.then(res => JSON.parse(res.result))
