環回遠程方法不接受參數或給出錯誤

slc loopback:remote-method

我試圖從資源管理器訪問該方法並把它送給狀態400與消息遠程方法「phoneNumber的是一個需要ARG」

當我嘗試郵遞員時，它給與狀態500與消息內部服務器錯誤。我嘗試發送發佈數據作爲表單，x-www-form-urlencoded編碼，並且行，它給出相同的結果。

服務器端錯誤：

模型JSON像這樣

{ 
    "name": "OneTimePassword", 
    "plural": "otp",

    "options": {

     "phoneNumber": { 
      "type": "number", 
      "required": true 
     }, 
    "otpNumber": { 
     "type": "number", 
     "required": true 
    }, 
    "resendCounter": { 
     "type": "number", 
     "default": "0" 
    }, 
    "createdDate": { 
     "type": "date" 
    } }, "validations": [], "relations": {}, "acls": [ 
    {

    }, 
    {

     "permission": "ALLOW", 
     "property": "deleteById" 
    }, 
    {

     "property": "getOTP" 
    } ], "methods": { 
    "getOTP": { 
     "accepts": [ 
     { 
      "arg": "phoneNumber", 
      "type": "number", 
      "required": true, 
      "description": "phone number", 
      "http": { 
      "source": "form" 
      } 
     } 
     ], 
     "returns": [ 
     { 
      "arg": "oneTimePassword", 
      "type": null,

     { 
      "path": "/getOTP", 
      "verb": "post" 
     } 
     ] 
    } } }

模型JS：

module.exports = function(Onetimepassword) { 
    /** 
    * generate otp and send sms 
    * @param {number} phoneNumber phone number 
    * @param {Function(Error,)} callback 
    */ 
    Onetimepassword.getOTP = function(phoneNumber, callback) { 
     var oneTimePassword = {}; 
     oneTimePassword.phoneNumber = phoneNumber; 
     // TODO 
     // logic will come here 
     // 
     callback(null, oneTimePassword); 
    }; 
    };

我缺少的東西？

我找到了解決辦法。

In model.json, Remote method's return type is null. I changed this to object type "OneTimePassword"

但我仍然無法從資源管理器中打開遠程方法。有一個錯誤issue#440。

使用郵遞員，請求工作正常

您有一個錯字。

符合oneTimePassword.phoneNumber = phoneNumber;您需要設置optNumber

我不這麼認爲。這是爲了不同的目的 – Manish

我發現了錯誤。請檢查下面的答案 – Manish
