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
查看版本号
C:\Users\dell>pip show httpie
Name: httpie
Version: 1.0.3
Summary: HTTPie - a CLI, cURL-like tool for humans.

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

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

}
