请求 - 返回一个元素

Question

喂！

所以让我们从输入我的代码和我遇到的错误开始。

这是我的代码：

login(token = 'string') {
         if (!token) throw "Veuillez entrer un token"
         request(
            {
                url : this.baseURL+this.endpoints[2],
                headers : {
                    "auth" : token
                }
            },
            function (err, response, body) {
                // Do more stuff with 'body' here
                if (err) throw err
                if (body.status == 401) throw "Le token "+token+" est invalide."
                this.token = token
                return "Logged in with "+token+" as "+body.username
            }
        );
     }

这是我用来测试我的客户的代码：

const c = require('./client/clienttest')
const client = new c()

let t=client.login("APITESTKORO")
console.log(t)

最后，登录控制台的东西。没那么难，就是undefined...

这就是我需要帮助的原因。我想登录Logged in with (token) as (username)。

希望有人能帮帮我！

尝试使用：

login(token = 'string',callback) {
         if (!token) throw "Veuillez entrer un token"
         request(
            {
                url : this.baseURL+this.endpoints[2],
                headers : {
                    "auth" : token
                }
            },
            function (err, response, body) {
                // Do more stuff with 'body' here
                if (err) throw err
                if (body.status == 401) throw "Le token "+token+" est invalide."
                this.token = token
                return callback("Logged in with "+token+" as "+body.username);
            }
        );
     }

这是测试我的客户端的代码：

const c = require('./client/clienttest')
const client = new c()
client.login("APITESTKORO",function(response){
    // Here you have access to your variable
    console.log(response);
})

希望对你有帮助。

你也可以试试yield， 尝试使用：

login(token = 'string') {
         if (!token) throw "Veuillez entrer un token"
         request(
            {
                url : this.baseURL+this.endpoints[2],
                headers : {
                    "auth" : token
                }
            },
            function (err, response, body) {
                // Do more stuff with 'body' here
                if (err) throw err
                if (body.status == 401) throw "Le token "+token+" est invalide."
                this.token = token
                return "Logged in with "+token+" as "+body.username
            }
        );
     }

并且，对于客户端测试：

const c = require('./client/clienttest')
const client = new c()

let t= yield client.login("APITESTKORO")
console.log(t)

终于，我的朋友 Ness 找到了！感谢他！

所以，我不想让它异步，让登录、执行等功能更容易。

这是他发给我的代码！

login(token = 'string') {
         if (!token) throw "Veuillez entrer un token"
         return new Promise ((resolve, reject) => {
          request(
            {
                url : this.baseURL+this.endpoints[2],
                headers : {
                    "auth" : token
                }
            },
            function (err, response, body) {
                // Do more stuff with 'body' here
                if (err) throw err
                if (body.status == 401) throw "Le token "+token+" est invalide."
                this.token = token
                resolve("Logged in with "+token+" as "+body.username)
            }
        );
        })
     }

并且，对于客户端测试：

let c = require('./client/clienttest'),
client = new c();

client.login("APITESTKORO").then(result => console.log(result))

再次感谢兄弟！
