python笔记42-http请求命令行工具(httpie)

前言

通常我们需要快速的测试某个接口通不通，一般linux上用curl去发http请求，但是这个命令行工具语法有点复杂了，不够直观。
python有一个给人类使用的requests库，非常的简单方便。httpie就是基于requests开发的，给人类用的命令行工具，取代curl的绝佳工具。

环境安装

pip install httpie==1.0.3

发送GET请求

get请求不需要带body参数，所以不带参数，会被默认识别成get请求

http http://127.0.0.1:8000/info

访问后查看结果，就是这么高效！

C:\Users\dell>http http://127.0.0.1:8000/info
HTTP/1.1 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Length: 290
Content-Type: application/json

[
    {
        "age": 20,
        "create_time": "2019-09-15",
        "id": 1,
        "mail": "283340479@qq.com",
        "name": "yoyo",
        "sex": "M"
    },
    {
        "age": 444444,
        "create_time": "2019-09-18",
        "id": 6,
        "mail": "283340479@qq.com",
        "name": "yoyo",
        "sex": "M"
    }
]

POST请求

GET请求是默认不带body部分的，那么带上body部分的参数，肯定会识别成POST请求，所以也不用声明请求类型。
一般接口是json类型的，所以头部请求参数类型Content-Type默认是application/json

接下来发个POST请求,比如我要发送的报文是这样的

POST http://127.0.0.1:8000/info HTTP/1.1
Host: 127.0.0.1:8000
User-Agent: HTTPie/1.0.3
Accept-Encoding: gzip, deflate
Accept: application/json, */*
Connection: keep-alive
Content-Type: application/json
Content-Length: 63

{"name": "yoyo", "sex": "M", "age": "20", "mail": "123@qq.com"}

那么用httpie的命令行只需下面简单的一行,如果参数是字符串，可以用key=value格式，如果参数不是字符串，那么用key:=value

http http://127.0.0.1:8000/info name=yoyo sex=M age=20 mail=123@qq.com

C:\Users\dell>http http://127.0.0.1:8000/info name=yoyo sex=M age=20 mail=123@qq.com
HTTP/1.1 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Length: 95
Content-Type: application/json
Date: Wed, 18 Sep 2019 14:22:22 GMT
Server: WSGIServer/0.2 CPython/3.6.0
Vary: Accept, Cookie
X-Frame-Options: SAMEORIGIN

{
    "data": {
        "age": "20",
        "mail": "123@qq.com",
        "name": "yoyo",
        "sex": "M"
    },
    "message": "create some data!"
}

json文件导入

如果json的参数较多，可以把请求参数写到一个json文件，如test.json

{
	"name": "yoyo",
	"sex": "M",
	"age": "20",
	"mail": "123@qq.com"
}

接下来发请求的时候，导入这个json文件就可以

http http://127.0.0.1:8000/info < test.json

测试结果

D:\>http http://127.0.0.1:8000/info < test.json
HTTP/1.1 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Length: 95
Content-Type: application/json

{
    "data": {
        "age": "20",
        "mail": "123@qq.com",
        "name": "yoyo",
        "sex": "M"
    },
    "message": "create some data!"
}
