使用 Chainlink 获取请求以检索返回 0x0000..00 作为响应的字符串

Question

I was following this tutorial in the Chainlink official docs: https://docs.chain.link/docs/make-a-http-get-request#config

I am using the AlphaChain Kovan oracle for retrieving bytes32: https://market.link/jobs/c2387021-cf1c-44a0-ae79-66fcdf39cff3?network=1

When the oracle gets the answer and runs fulfill(), it assigns the string it received to my "name " variable (a bytes32 variable). The transaction seems to go through when I call the oracle, but when I click on the "name" variable, the variable only shows 0x0000...00, what's going on?

Answer 1

The 0x00000.... is the default value "name" is set to when the contract is deployed. After you send the request you need to give the node time to respond and for their response transaction to be included in the blockchain. So after you send the request give it about 30 secs to a minute and check again and the value in "name" should reflect the string you retrieved in 32 Bytes.
