获取已经验证代码合约的ABI
Verified Contract Source Codes

A simple sample for retrieving the contractABI using Web3.js and Jquery to interact with a contract
var Web3 = require('web3'); var web3 = new Web3(new Web3.providers.HttpProvider()); var version = web3.version.api; $.getJSON('http://api.etherscan.io/api?module=contract&action=getabi&address=0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359', function (data) { var contractABI = ""; contractABI = JSON.parse(data.result); if (contractABI != ''){ var MyContract = web3.eth.contract(contractABI); var myContractInstance = MyContract.at("0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359"); var result = myContractInstance.memberId("0xfe8ad7dd2f564a877cc23feea6c0a9cc2e783715"); console.log("result1 : " + result); var result = myContractInstance.members(1); console.log("result2 : " + result); } else { console.log("Error" ); } });

[BETA] 验证源代码
1. Requires a valid Etherscan APIkey, will reject if otherwise 2. Current daily limit of 100 submissions per day per user (subject to change) 3. Only supports HTTP post due to max transfer size limitations for http get 4. Supports up to 10 different library pairs 5. Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files. You can try using the Blockcat solidity-flattener or SolidityFlattery 6. List of supported solc versions, only solc version v0.4.11 and above is supported. Ex. v0.4.25+commit.59dbf8f1 7. Upon successful submission you will receive a GUID (50 characters) as a receipt. 8. You may use this GUID to track the status of your submission 9. Verified Source Codes will be displayed at contractsVerified
See Demo Source Verification Submission Code at Source Code Verification Sample
Source Code Submission Gist (returns a guid as part of the result upon success):
//Submit Source Code for Verification $.ajax({ type: "POST", //Only POST supported url: "//api.etherscan.io/api", //Set to the correct API url for Other Networks data: { apikey: $('#apikey').val(), //A valid API-Key is required module: 'contract', //Do not change action: 'verifysourcecode', //Do not change contractaddress: $('#contractaddress').val(), //Contract Address starts with 0x... sourceCode: $('#sourceCode').val(), //Contract Source Code (Flattened if necessary) contractname: $('#contractname').val(), //ContractName compilerversion: $('#compilerversion').val(), // see http://etherscan.io/solcversions for list of support versions optimizationUsed: $('#optimizationUsed').val(), //0 = Optimization used, 1 = No Optimization runs: 200, //set to 200 as default unless otherwise constructorArguements: $('#constructorArguements').val(), //if applicable libraryname1: $('#libraryname1').val(), //if applicable, a matching pair with libraryaddress1 required libraryaddress1: $('#libraryaddress1').val(), //if applicable, a matching pair with libraryname1 required libraryname2: $('#libraryname2').val(), //if applicable, matching pair required libraryaddress2: $('#libraryaddress2').val(), //if applicable, matching pair required libraryname3: $('#libraryname3').val(), //if applicable, matching pair required libraryaddress3: $('#libraryaddress3').val(), //if applicable, matching pair required libraryname4: $('#libraryname4').val(), //if applicable, matching pair required libraryaddress4: $('#libraryaddress4').val(), //if applicable, matching pair required libraryname5: $('#libraryname5').val(), //if applicable, matching pair required libraryaddress5: $('#libraryaddress5').val(), //if applicable, matching pair required libraryname6: $('#libraryname6').val(), //if applicable, matching pair required libraryaddress6: $('#libraryaddress6').val(), //if applicable, matching pair required libraryname7: $('#libraryname7').val(), //if applicable, matching pair required libraryaddress7: $('#libraryaddress7').val(), //if applicable, matching pair required libraryname8: $('#libraryname8').val(), //if applicable, matching pair required libraryaddress8: $('#libraryaddress8').val(), //if applicable, matching pair required libraryname9: $('#libraryname9').val(), //if applicable, matching pair required libraryaddress9: $('#libraryaddress9').val(), //if applicable, matching pair required libraryname10: $('#libraryname10').val(), //if applicable, matching pair required libraryaddress10: $('#libraryaddress10').val() //if applicable, matching pair required }, success: function (result) { console.log(result); if (result.status == "1") { //1 = submission success, use the guid returned (result.result) to check the status of your submission. // Average time of processing is 30-60 seconds document.getElementById("postresult").innerHTML = result.status + ";" + result.message + ";" + result.result; // result.result is the GUID receipt for the submission, you can use this guid for checking the verification status } else { //0 = error document.getElementById("postresult").innerHTML = result.status + ";" + result.message + ";" + result.result; } console.log("status : " + result.status); console.log("result : " + result.result); }, error: function (result) { console.log("error!"); document.getElementById("postresult").innerHTML = "Unexpected Error" } });

//Check Source Code Verification Status $.ajax({ type: "GET", url: "//api.etherscan.io/api", data: { guid: 'ezq878u486pzijkvvmerl6a9mzwhv6sefgvqi5tkwceejc7tvn', //Replace with your Source Code GUID receipt above module: "contract", action: "checkverifystatus" }, success: function (result) { console.log("status : " + result.status); //0=Error, 1=Pass console.log("message : " + result.message); //OK, NOTOK console.log("result : " + result.result); //result explanation $('#guidstatus').html(">> " + result.result); }, error: function (result) { alert('error'); } });
