Harmony开发【笔记1】报错解决（字段名写错了。。）

在利用axios从网络接收请求时，发现返回obj的code为"-1"，非常不解，利用console.log测试，更加不解，可知抛出错误是 " E 其他错误: userName required"。但是我在测试时，它并没有体现为空，

复制代码

if (!data.useName) {
    console.error("userName 为空或未提供");
    throw new Error("userName 为空或未提供");
  }

为此，我在多处测试，日志如下

 I     返回参数 {"useName":"18070538251","passWord":"040726"}

仍然不解，先记录，后续后思路再回来解答。

很明显我的字段名错了。。。

利用postman调试时终于又认真认真看了一遍，难绷哈。之前还在想是不是后端数据没掉了。但说真的，我的debug能力还是要增强，关于网络部分我也不是很熟悉。哎。

但还是恭喜我吧哈哈哈。
