node.js - 我想使用 Alamofire 在我的 swift 代码上使用登录 API (node.js)

Question

我在尝试登录时遇到错误:这是我的登录服务，我确信它工作得很好，因为我在 postman 上测试了它，并且我已经在 android 上使用它，并且它工作得很好，加密的密码和盐工作得很好..

app.post('/login/',(req,res,next)=>{
    var post_data = req.body;

    //Extract email and password from request
    var user_password = post_data.password;
    var email = post_data.email;

    con.query('SELECT * FROM user where email=?',[email],function (err,result,fields) {
        con.on('error', function (err) {
            console.log('[MYSQL ERROR]', err);
        });
        if (result && result.length)

        {
            var salt = result[0].salt;
            var encrypted_password = result[0].encrypted_password;
            var hashed_password = checkHashPassword(user_password, salt).passwordHash;
        if (encrypted_password == hashed_password)
            res.end(JSON.stringify(result[0]))
        else
            res.end(JSON.stringify('Wrong Password'))


        }

        else {

                res.json('user not exists!!');

            }

    });


})

这是我关于 btn_login 操作的快速代码，我使用 Alamofire，他向我显示了 url 的错误，但我使用相同的 url 来显示我的表中的数据，效果很好

    @IBAction func btn_login(_ sender: Any) {


        let serverUrl = "https://127.0.0.1:1337/login"


        guard let email = emailtf.text, !email.isEmpty else {return}
        guard let password = passwordtf.text, !password.isEmpty else {return}


      let loginRequest = [
                   "email" : email,
                   "password" : password
               ]

        Alamofire.request(serverUrl, method: .post, parameters: loginRequest, encoding: JSONEncoding.default, headers: nil)
            .validate(statusCode:200..<300)
                .responseJSON { response in
                    switch response.result {
                    case .success(let value):
                        print(value)


                        break
                    case .failure(let error):
                        print(error)

                        break
                    }
            }
    }

我在 xcode 控制台上收到此错误

["Email": "test", "Password": "test"]

请问有什么帮助吗？谢谢

在 url 中输入您的本地 IP 而不是 localhost 。例如http://192.168.1.34:1337/

另外尝试在您的 Alamofire 请求中添加 header 。这是一个例子:

let loginRequest = [
        "Email" : self.emailtf.text! as String,
        "Password" : self.passwordtf.text! as String
    ]
let headers = ["Content-Type" : "application/json"]

Alamofire.request(url, method : .post, parameters : loginRequest, encoding : 
JSONEncoding.default , headers : headers).responseData { dataResponse in

 print(dataResponse.request as Any) // your request 
 print(dataResponse.response as Any) // your response
 }
