在azure函数内部发出一个https请求 [英] making an https request inside of an azure function

问题描述

我正在尝试一个简单的请求:

I'm attempting a simple request:

var options = {
                host: 'hookb.in',
                path: '/8PMoEa9kbaCXgXYxOmdr5',
                method: 'POST'
            };

            var req = http.request(options, (res) => {
                var body = context.bindingData.name;

                res.on("data", (chunk) => {
                    body += chunk;
                });

                res.on("end", () => {
                    context.res = body;
                });
            }).on("error", (error1) => {
                context.log('error');
                context.res = {
                    status: 500,
                    body: error1
                };
            });
            req.end();
            context.done();

但是，没有响应(目标没有收到任何请求， https://hookbin.com/8PMoEa9kbaCXgXYxOmdr

However, there's no response (and no request received by the target here https://hookbin.com/8PMoEa9kbaCXgXYxOmdr).

我在做什么错?有没有一种特殊的方法可以在azure函数内部创建https请求?

var Jimp = require("jimp");
var http = require('https');

module.exports = async function (context, myBlob) {
    context.log("JavaScript blob trigger function processed blob \n Name:", context.bindingData.name, "\n Blob Size:", myBlob.length, "Bytes");
    context.log(process.env.ImageConvertedWebHook);
    Jimp.read(myBlob, function (err, image) {
        image.getBufferAsync(Jimp.MIME_TIFF, function (error, imageData) {
            context.log('Node.JS blob trigger function resized ' + context.bindingData.name + ' to ' + image.bitmap.width + 'x' + image.bitmap.height);
            context.bindings.outputBlob = imageData;

            var options = {
                host: 'hookb.in',
                path: '/8PMoEa9kbaCXgXYxOmdr5',
                method: 'POST'
            };

            var req = http.request(options, (res) => {
                var body = context.bindingData.name;

                res.on("data", (chunk) => {
                    body += chunk;
                });

                res.on("end", () => {
                    context.res = body;
                });
            }).on("error", (error1) => {
                context.log('error');
                context.res = {
                    status: 500,
                    body: error1
                };
            });
            req.end();
            context.done();
        });
    });
};

我也尝试过这种方式:

    const data = 'buy milk biotch';
    var options = {
        host: 'hookb.in',
        path: '/8PMoEa9kbaCXgXYxOmdr',
        method: 'POST',
        port: 443,
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': data.length
        }
    };
    const req = https.request(options, res => {
        context.log(`statusCode: ${res.statusCode}`)

        res.on('data', d => {
            context.log(d)
        })
    })

    req.on('error', error1 => {
        context.log(error1)
    })

    req.write(data)
    req.end()

推荐答案

似乎是命名冲突问题.代码中要更改的变量对:

Seems like naming conflict issue .Couple of variables to change in your code:

• 在下面更改

var http = require('https');

收件人

var httpMod = require('https');

• 在下面更改

const req = https.request(options, res => {
            context.log(`statusCode: ${res.statusCode}`)
    
            res.on('data', d => {
                context.log(d)
            })
        })

收件人

 const customReq = httpMod.request(options, res => {
            context.log(`statusCode: ${res.statusCode}`)
    
            res.on('data', d => {
                context.log(d)
            })
        })
