title: 使用 Chai-HTTP III 的 PUT 方法对 API 请求运行功能测试

# --description--
请注意,本项目在[这个 Replit 项目](https://replit.com/github/freeCodeCamp/boilerplate-mochachai)的基础上进行开发。你也可以从 [GitHub](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 上克隆。
接下来,我们将了解如何使用请求的 payloadbody发送数据。 我们需要测试一个 PUT 请求, `'/travellers'` 接收如下的 JSON 对象:
```json
{
"surname": [last name of a traveller of the past]
}
```
路由响应如下:
```json
{
"name": [first name], "surname": [last name], "dates": [birth - death years]
}
```
更多细节请查看服务器代码。
# --instructions--
`tests/2_functional-tests.js` 中,修改 `'send {surname: "Colombo"}'` 测试(`// #3`
发送以下 JSON 响应作为有效载荷:
```json
{
"surname": "Colombo"
}
```
`request.end` 返回中检查以下情况:
1. `status`
2. `type`
3. `body.name`
4. `body.surname`
请按照以上顺序书写断言,顺序错误会影响系统判定。 完成后,请务必移除 `assert.fail()`
# --hints--
应通过所有测试。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
(data) => {
assert.equal(data.state, 'passed');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
应测试 “res.status” 是否为 200。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
(data) => {
assert.equal(data.assertions[0].method, 'equal');
assert.equal(data.assertions[0].args[0], 'res.status');
assert.equal(data.assertions[0].args[1], '200');
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要测试 “res.type” 是否为 “application/json”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
(data) => {
assert.equal(data.assertions[1].method, 'equal');
assert.equal(data.assertions[1].args[0], 'res.type');
assert.match(data.assertions[1].args[1], /('|")application\/json\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要测试 “res.body.name” 是否为 “Cristoforo”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
(data) => {
assert.equal(data.assertions[2].method, 'equal');
assert.equal(data.assertions[2].args[0], 'res.body.name');
assert.match(data.assertions[2].args[1], /('|")Cristoforo\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
需要测试 “res.body.surname” 是否为 “Colombo”。
```js
(getUserInput) =>
$.get(getUserInput('url') + '/_api/get-tests?type=functional&n=2').then(
(data) => {
assert.equal(data.assertions[3].method, 'equal');
assert.equal(data.assertions[3].args[0], 'res.body.surname');
assert.match(data.assertions[3].args[1], /('|")Colombo\1/);
},
(xhr) => {
throw new Error(xhr.responseText);
}
);
```
