以太坊：智能合约(Contracts)

智能合约相关的 API，接口的参数说明请参考Etherscan API 约定, 文档中不单独说明。

Newly verified Contracts are synced to the API servers within 5 minutes or less

获取已经验证代码合约的ABI

Verified Contract Source Codes

https://api.etherscan.io/api?module=contract&action=getabi&address=0xBB9bc244D798123fDe783fCc1C72d3Bb8C189413&apikey=YourApiKeyToken

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" );}            });

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 Networksdata: {apikey: $('#apikey').val(),                     //A valid API-Key is required        module: 'contract',                             //Do not changeaction: 'verifysourcecode',                     //Do not changecontractaddress: $('#contractaddress').val(),   //Contract Address starts with 0x...     sourceCode: $('#sourceCode').val(),             //Contract Source Code (Flattened if necessary)contractname: $('#contractname').val(),         //ContractNamecompilerversion: $('#compilerversion').val(),   // see http://etherscan.io/solcversions for list of support versionsoptimizationUsed: $('#optimizationUsed').val(), //0 = Optimization used, 1 = No Optimizationruns: 200,                                      //set to 200 as default unless otherwise         constructorArguements: $('#constructorArguements').val(),   //if applicablelibraryname1: $('#libraryname1').val(),         //if applicable, a matching pair with libraryaddress1 requiredlibraryaddress1: $('#libraryaddress1').val(),   //if applicable, a matching pair with libraryname1 requiredlibraryname2: $('#libraryname2').val(),         //if applicable, matching pair requiredlibraryaddress2: $('#libraryaddress2').val(),   //if applicable, matching pair requiredlibraryname3: $('#libraryname3').val(),         //if applicable, matching pair requiredlibraryaddress3: $('#libraryaddress3').val(),   //if applicable, matching pair requiredlibraryname4: $('#libraryname4').val(),         //if applicable, matching pair requiredlibraryaddress4: $('#libraryaddress4').val(),   //if applicable, matching pair requiredlibraryname5: $('#libraryname5').val(),         //if applicable, matching pair requiredlibraryaddress5: $('#libraryaddress5').val(),   //if applicable, matching pair requiredlibraryname6: $('#libraryname6').val(),         //if applicable, matching pair requiredlibraryaddress6: $('#libraryaddress6').val(),   //if applicable, matching pair requiredlibraryname7: $('#libraryname7').val(),         //if applicable, matching pair requiredlibraryaddress7: $('#libraryaddress7').val(),   //if applicable, matching pair requiredlibraryname8: $('#libraryname8').val(),         //if applicable, matching pair requiredlibraryaddress8: $('#libraryaddress8').val(),   //if applicable, matching pair requiredlibraryname9: $('#libraryname9').val(),         //if applicable, matching pair requiredlibraryaddress9: $('#libraryaddress9').val(),   //if applicable, matching pair requiredlibraryname10: $('#libraryname10').val(),       //if applicable, matching pair requiredlibraryaddress10: $('#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 secondsdocument.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 = errordocument.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"}});
