注册用户之后的nodejs错误请求

Question

我注册用户后收到了错误的请求。插入mongolab的数据很好，但它会呈现一个“错误请求”的页面。我检查了我的代码一百次，我发现它没有任何问题。

谢谢

用户模型

np.outer(a, b.flatten()).reshape(a.shape + b.shape)

EJS

var UserSchema = new Schema({
    username: {type:String,
         lowercase: true,
         require: true
    },

    email: String,
    isAdmin: String,
    password: {type: String,
         require: true
    }
});

路线 //注册用户

<form action="/user/register" method="POST">
      <div class="form-group">
         <label>Username: </label><input type="text" placeholder="username" name="username" class="form-control" />
      </div>

      <div class="form-group">
         <label>Email:</label> <input type="email" placeholder="email" name="email" class="form-control" />
      </div>

      <div class="form-group">
         <label>Password:</label> <input type="password" placeholder="password" name="password1" class="form-control" />
      </div>

      <div class="form-group">
         <label>Retype Password: </label><input type="password" placeholder="passowrd" name="password2" class="form-control" />
      </div>

      <button class="btn btn-success btn-lg">Register</button>
    </form>
