錯誤：提供的地址“6.963865902119903e+47”無效

完整的錯誤日誌：

formatters.js:471 Uncaught Error: Provided address "6.963865902119903e+47" is invalid, the capitalization checksum test failed, or its an indrect IBAN address which can't be converted.

當我嘗試在 Chrome 瀏覽器中執行 index.html 時出現此錯誤。我預計這與此程式碼是從本教程中複製的事實有關，該教程已有 1.5 年的歷史。

這是我的目錄

原來我忘了把合約的實例地址放在引號裡！

請參閱此程式碼段的最後一行：

var ethereumSessionInstance = new web3.eth.Contract([
   {
       "constant": false,
       "inputs": [
           {
               "name": "_myInt",
               "type": "uint256"
           }
       ],
       "name": "setTheInt",
       "outputs": [],
       "payable": false,
       "stateMutability": "nonpayable",
       "type": "function"
   },
   {
       "constant": true,
       "inputs": [],
       "name": "getTheInt",
       "outputs": [
           {
               "name": "",
               "type": "uint256"
           }
       ],
       "payable": false,
       "stateMutability": "view",
       "type": "function"
   },
   {
       "inputs": [
           {
               "name": "_myInt",
               "type": "uint256"
           }
       ],
       "payable": false,
       "stateMutability": "nonpayable",
       "type": "constructor"
   }
], "0x79fB0E00F4dB8812b04Ae84816BbccAF941E5c90");

通過在地址周圍加上引號解決了該錯誤。

在 Javascript 中，類型0x79fB0E00F4dB8812b04Ae84816BbccAF941E5c90是Number.

然而，這個數字的值大於Number.MAX_SAFE_INTEGER53 位長。

Solidity 地址類型為 160 位長，它們作為字元串傳遞給 web3.js 函式或從 web3.js 函式傳遞。

因此，您應該始終在 Javascript 程式碼中的任何地址值周圍使用引號。
