Question

这是AWS Lambda函数中的代码：

var https = require('https');
exports.handler = (event, context, callback) => {
    var params = {
        host: "bittrex.com",
        path: "/api/v1.1/public/getmarketsummaries"
    };
    var req = https.request(params, function(res) {
        var test = res.toString();
        console.log(JSON.parse(test));
        //console.log(JSON.parse(res.toString()));
    });
    req.end();
};

错误：getaddrinfo ENOTFOUND https://bittrex.com https://bittrex.com:443 在errnoException（dns.js：28：10）在GetAddrInfoReqWrap.onlookup [as oncomplete]（dns.js：76：26）

我无法想象，请帮忙。其他解决方案无效。

从主机中删除#Tested on python3 import fileinput import csv import random import glob import os textToSearch = 'Button1' with open('dict.csv', 'r') as f: reader = csv.reader(f) your_list = list(reader) path='F:\Release1' type(path) extension = 'xaml' os.chdir(path) result = [i for i in glob.glob('*.{}'.format(extension))] for i in range(0,len(result)): fileToSearch = path + '\\' + result[i] tempFile = open( fileToSearch, 'r+' ) for line in fileinput.input( fileToSearch ): if textToSearch in line : print('Match Found') else: print('Match Not Found!!') i=random.randint(0,717) #numbers of words in dic textToReplace = str(your_list[i]).replace("'","").replace("[","").replace("]","") tempFile.write( line.replace( textToSearch, textToReplace ) ) tempFile.close() # #。要求已经说明你正在使用https / SSL。

我修改了您的代码，以便在AWS Lambda Node.js 6.10中正常运行。我将Lambda超时设置为60秒进行测试。

最大的变化是添加“res.on（'data'，function（chunk）{}：”和“res.on（'end'，function（）{}”。

var https = require('https');
exports.handler = (event, context, callback) => {
    var params = {
        host: "bittrex.com",
        path: "/api/v1.1/public/getmarketsummaries"
    };
    var req = https.request(params, function(res) {
        let data = '';
        console.log('STATUS: ' + res.statusCode);
        res.setEncoding('utf8');
        res.on('data', function(chunk) {
            data += chunk;
        });
        res.on('end', function() {
            console.log("DONE");
            console.log(JSON.parse(data));
        });
    });
    req.end();
};

问题出在您的安全组中。看起来您的lambda无权解析DNS。检查lambda sec组是否启用了端口53 UDP和TCP。
