错误：NodeJS HTTPS请求中的自签名证书

Question

我对NodeJS还是很陌生，我正尝试通过GoDaddy证书将来自NodeJS（后端）的HTTPS请求直接实现到IISNode中托管的中间件api。我的视图（前端）有另一个存储库，并且通过浏览器对中间件api的所有调用都在使用GoDaddy证书。使用Axios进行的HTTP调用可以正常工作。从NodeJS后端使用HTTPS调用中间件api时，我得到：

Error: self signed certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1058:34)
    at TLSSocket.emit (events.js:198:13)
    at TLSSocket.EventEmitter.emit (domain.js:448:20)
    at TLSSocket._finishInit (_tls_wrap.js:636:8)

真的很奇怪，前端回购通过浏览器没有问题地与中间件通信，但是NodeJS后端调用却没有。我尝试在后端使用Axios，但没有出现运气和证书错误。我切换到HTTPS，并且GET调用正常运行，但是POST调用给了我上面的错误。

我已经阅读了大量有关自签名证书的帖子和示例，但是我使用的是从GoDaddy生成的证书。这是我尝试过的一些代码片段：

Axios：

    const SSLAgent = new https.Agent({
        rejectUnauthorized: true,
        passphrase: process.env.PASSPHRASE,
        pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX),
        ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
    });


    const fetchData = () => axios.get(`${process.env.MIDDLE_WARE_URL}/something`, {
        headers: {
            Authorization: `Bearer ${token}`
        },
        httpsAgent: SSLAgent
    });


    const uploadData = () => {
        const form = new FormData();
        form.append("data", fs.createReadStream(dataPath));
        return axios.post(`${process.env.MIDDLE_WARE_URL}/data`, form, {
            headers: {
                ...form.getHeaders(),
                Authorization: `Bearer ${token}`
            },
            httpsAgent: SSLAgent
        });
    };

    const fetchItemImage = (ItemID: number) => axios.get(`${process.env.MIDDLE_WARE_URL}/item/${ItemID}/image.png`, {
        responseType: "arraybuffer",
        headers: {Authorization: `Bearer ${token}`},
        httpsAgent: new https.Agent({pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX), passphrase: process.env.PASSPHRASE}), ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
    });

HTTPS：

        const SSLAgent = {
        rejectUnauthorized: true,   
        passphrase: process.env.PASSPHRASE,
        pfx: fs.readFileSync(path.join(__dirname, "../../") + process.env.PFX),
        ca: fs.readFileSync(path.join(__dirname, "../../") + process.env.CRT_BUNDLE)
    };

    const middleServer = express;
    const middle = express.Router();
    https.createServer(SSLAgent, middleServer).listen(443);

    let data;
    const dataOptions = {
        headers: {
            "Authorization": `Bearer ${token}`
        }
    };
    const fetchData = () => middle.get("/data", (req, res) => {
        console.log("The req is: ", req);
        if (res.statusCode === 200) {
            console.log("The Fetch Data Res: ", res);
            data = res;
        }
        data = [];
    });

    const uploadStuff = () => {
        const form = new FormData();
        form.append("Stuff", fs.createReadStream(stuffPath));
        const stuffOptions = {
            headers: {
                ...form.getHeaders(),
               "Authorization": `Bearer ${token}`
            },
            form
        };
        return  middle.post("/stuff", (req, res) => {
            req.params(stuffOptions);
            res.on("data", () => {
                console.log("The post response is: ", res);
            });
            res.on("error", (error) => {
                console.log("The post error is: ", error);
            });
        });
    };
