HTTP响应状态码 例子

如何自定义 HTTP 响应状态码

执行失败,默认状态码为 500 执行成功,默认状态码为 200

1. 默认错误

接口设计如下:

```js
// 默认错误, http 响应状态码 为 `500`
ctx.resultObj.err="演示-自定义错误"

```

接口返回

```json
{
    "error": {
        "code": "ERR_BAD_RESPONSE",
        "message": "Request failed with status code 500",
        "headers": {
            "Accept": "application/json, text/plain, */*",
            "Content-Type": "application/json;charset=UTF-8",
        },
        "method": "post",
        "status": 500,
        "response": {
            "data": {
                "code": "API_GATEWAY_SERVER_ERROR",
                "message": "演示-自定义错误"
            }
        }
    }
}
```

2. 自定义异常的 http 响应状态码

 自定义异常的 http 响应状态码如 401,接口设计如下:

```js
// 自定义 
ctx.resultObj.err = {
    status: 401,
    message: '演示-自定义错误-401'
}
```

接口返回

```json
{
    "error": {
        "code": "ERR_BAD_REQUEST",
        "message": "Request failed with status code 401",
        "headers": {
           "Accept": "application/json, text/plain, */*",
           "Content-Type": "application/json;charset=UTF-8",
         },
        "method": "post",
        "status": 401,
        "response": {
            "data": {
                "message": "演示-自定义错误-401"
            }
        }
    }
}
```

3. 执行成功

此示例中 将 http 请求参数 也一起返回了,
