- 带有环境变量
- 带有动态参数
说明
首先通过###三个井号键来分开每个请求体，然后请求url和header参数是紧紧挨着的，请求参数不管是POST的body传参还是GET的parameter传参，都是要换行的，需要遵守HTTP协议规范
GET请求
### GET request with a header
GET https://httpbin.org/ip
Accept: application/json### GET request with parameter
GET https://httpbin.org/get?show_env=1
Accept: application/json### GET request with environment variables
GET {{host}}/get?show_env={{show_env}}
Accept: application/json### GET request with disabled redirects
# @no-redirect
GET http://httpbin.org/status/301### GET request with dynamic variables
GET http://httpbin.org/anything?id={{$uuid}}&ts={{$timestamp}}###POST请求
### Send POST request with json body
POST https://httpbin.org/post
Content-Type: application/json{"id": 999,"value": "content"
}### Send POST request with body as parameters
POST https://httpbin.org/post
Content-Type: application/x-www-form-urlencodedid=999&value=content### Send a form with the text and file fields
POST https://httpbin.org/post
Content-Type: multipart/form-data; boundary=WebAppBoundary--WebAppBoundary
Content-Disposition: form-data; name="element-name"
Content-Type: text/plainName
--WebAppBoundary
Content-Disposition: form-data; name="data"; filename="data.json"
Content-Type: application/json< ./request-form-data.json
--WebAppBoundary--### Send request with dynamic variables in request's body
POST https://httpbin.org/post
Content-Type: application/json{"id": {{$uuid}},"price": {{$randomInt}},"ts": {{$timestamp}},"value": "content"
}###
效果
点击项目目录，右键操作，new，Http Request
hello.http
GET http://localhost:8080/validSingleColumn
Accept: application/json
RUN 返回信息
GET http://localhost:8080/validSingleColumnHTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 06:28:03 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "操作成功","code": 200,"data": ["1","2","3","4","5"]
}Response code: 200; Time: 49ms; Content length: 54 bytes
在resource下面新建一个包，如rest、http之类的，名字随便取，在这里面我们来创建我们的请求。
创建GET请求
没有参数
GET http://localhost:8080/hello
Accept: application/jsoncontroller
@GetMapping(value = "hello")public AjaxResult hello(){return AjaxResult.success("hello");}
响应信息
GET http://localhost:8080/helloHTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 06:41:52 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "hello","code": 200
}Response code: 200; Time: 279ms; Content length: 26 bytes带有参数
第一种形式:使用@RequestParam单个参数
@GetMapping(value = "/getFirst")public AjaxResult getFirst(@RequestParam String id) {log.info("id:【{}】", id);return AjaxResult.success("使用@RequestParam单个参数");}
GET http://localhost:8081/hello/getFirst?id=1
Accept: application/json
GET http://localhost:8081/hello/getFirst?id=1HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 06:59:52 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "使用@RequestParam单个参数","code": 200
}Response code: 200; Time: 62ms; Content length: 40 bytes
第二种方式：不使用@RequestParam单个参数
@GetMapping(value = "getSecond")
public AjaxResult getSecond(String id) {log.info("id:【{}】", id);return AjaxResult.success("不使用@RequestParam单个参数。");
}
GET http://localhost:8081/hello/getSecond?id=2
Accept: application/jsonGET http://localhost:8081/hello/getSecond?id=2HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 07:01:52 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "不使用@RequestParam单个参数。","code": 200
}Response code: 200; Time: 14ms; Content length: 42 bytes第三种方式：多个基础参数
@GetMapping(value = "getThird")public AjaxResult getThird(String id, int age) {log.info("id:【{}】,age:【{}】", id, age);return AjaxResult.success("多个参数");}
GET http://localhost:8081/hello/getThird/?id=18&age=16
Accept: application/json
GET http://localhost:8081/hello/getThird/?id=18&age=16HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 07:05:24 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "多个参数","code": 200
}Response code: 200; Time: 15ms; Content length: 25 bytes第四种方式：多个参数使用@RequestParam
@GetMapping(value = "getFourth")public AjaxResult getFourth(@RequestParam String id, @RequestParam int age) {log.info("id:【{}】,age:【{}】", id, age);return AjaxResult.success("多个参数使用@RequestParam");}
GET http://localhost:8081/hello/getFourth?id=18&age=16
Accept: application/jsonGET http://localhost:8081/hello/getFourth?id=18&age=16HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 07:07:19 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "多个参数使用@RequestParam","code": 200
}Response code: 200; Time: 20ms; Content length: 40 bytes第五种方式：map入参使用@RequestParam，其实加不加一样效果
@GetMapping(value = "getFifth")public AjaxResult getFifth(@RequestParam Map map) {log.info("map:【{}】", map);return AjaxResult.success("map使用@RequestParam");}
GET http://localhost:8081/hello/getFifth?id=1&age=10
Accept: application/json
GET http://localhost:8081/hello/getFifth?id=1&age=10HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 07:13:03 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "map使用@RequestParam","code": 200
}Response code: 200; Time: 13ms; Content length: 39 bytes第六种：实体类使用
@GetMapping(value = "getSeven")public AjaxResult getSeven(User user) {log.info("user:【{}】", user);return AjaxResult.success("实体类");}
GET http://localhost:8081/hello/getSeven?id=10&age=10&userName=pmb
Accept: application/json
GET http://localhost:8081/hello/getSeven?id=10&age=10&userName=pmbHTTP/1.1 200
X-xr-bookmark: 1b995c1b-c0c7-4b3b-8d9b-9c0c008f7b32
Content-Type: application/json
Transfer-Encoding: chunked
Date: Thu, 27 Jul 2023 07:30:10 GMT
Keep-Alive: timeout=60
Connection: keep-alive{"msg": "实体类","code": 200
}Response code: 200; Time: 75ms; Content length: 24 bytes
总结：接收一个参数（String、Long），接收一个集合（Map）
GET 请求 测试发现 使用 @RequestParm 可以接收到参数
GET 请求 测试发现 不加 @RequestParm 也可以接收到参数
接受一个对象（user）
GET 请求 测试发现 使用 @RequestParm 接收对象 报错 接收不到
GET 请求 测试发现 不加 @RequestParm 接收对象 可以接收
总结：
GET 请求 当使用 @RequestParm 注解 和 不加注解时，只能接收到 params 携带的参数 ，参数放在 请求头 和请求体中均接受不到。
带有环境变量
带有动态参数
接收一个参数（String、Long、Integer）@RequestParm 可以。
接收一个集合（Map）@RequestParm 和 @RequestBody 均可以。
接收一个对象（user） @RequestBody 均可以。
总结：POST请求 当使用 @RequestParm 注解 和 不加注解时，只能接收到 params 和请求体xxx格式携带的参数，加注解无法接收到对象参数。
