当你测试一个 `PUT` 请求时,你经常会随同它一起发送数据。 你在 `PUT` 请求中包含的数据被称为请求的主体。

要将 `PUT` 请求和 JSON 对象发送到 `'/travellers'` 端点,你可以使用 `chai-http` 插件的 `put` 和 `send` 方法:
|
|
|
|
|
|
|
|
```js
|
|
|
|
chai
|
|
|
|
.request(server)
|
|
|
|
.put('/travellers')
|
|
|
|
.send({
|
|
|
|
"surname": [last name of a traveller of the past]
|
|
|
|
})
|
|
|
|
...
|
2020-09-17 03:50:23 -07:00
|
|
|
```
|
|
|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
并且路由响应如下:
|
2020-12-16 00:37:30 -07:00
|
|
|
|
2020-09-17 03:50:23 -07:00
|
|
|
```json
|
|
|
|
{
|
2021-09-03 01:11:45 -07:00
|
|
|
"name": [first name],
|
|
|
|
"surname": [last name],
|
|
|
|
"dates": [birth - death years]
|
2020-09-17 03:50:23 -07:00
|
|
|
}
|
|
|
|
```
|
|
|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
请参阅服务器代码以了解对 `'/travellers'` 端点的不同响应。

在 `tests/2_functional-tests.js` 中,更改 `'Send {surname: "Colombo"}'` 测试(`// #3`),并使用 `put` 和 `send` 方法来测试 `'/travellers'` 端点。

|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
在你的 PUT 请求中发送以下 JSON 对象。
|
2020-09-17 03:50:23 -07:00
|
|
|
|
|
|
|
```json
|
|
|
|
{
|
|
|
|
"surname": "Colombo"
|
|
|
|
}
|
|
|
|
```

2018-10-10 18:03:03 -04:00
|
|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
在 `request.end` 的返回中检查以下情况:
|
2021-02-06 04:42:36 +00:00
|
|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
1. `status` 应该是 `200`
|
|
|
|
2. `type` 应该是 `application/json`
|
|
|
|
3. `body.name` 应该是 `Cristoforo`
|
|
|
|
4. `body.surname` 应该是 `Colombo`
|
2021-02-06 04:42:36 +00:00
|
|
|
|
2021-09-03 01:11:45 -07:00
|
|
|
请按照以上顺序书写断言,顺序错误会影响系统判定。 此外,请确保在完成后删除 `assert.fail()`。
