http库测试工具 - httpbin
(图片来自互联网)
如果一个人想学习爬虫技术，我会首先推荐他学会使用httpbin！
httpbin(官网|github)是一个很不错测试工具，你可以放心大胆的黑他，而不用担心他报复你。他有点像一个蜜罐，时刻等待着你的光临，然后根据你的请求，给你返回你想要的东西

类似这种能够很方便调试接口的还有很多，但是无疑还是httpbin最好用。
如何使用
使用你擅长的语言，与它的接口互动。
接口
| Endpoint | Description |
| / | This page. |
| /ip | Returns Origin IP. |
| /user-agent | Returns user-agent. |
| /headers | Returns header dict. |
| /get | Returns GET data. |
| /post | Returns POST data. |
| /patch | Returns PATCH data. |
| /put | Returns PUT data. |
| /delete | Returns DELETE data |
| /gzip | Returns gzip-encoded data. |
| /deflate | Returns deflate-encoded data. |
| /status/:code | Returns given HTTP Status code. |
| /response-headers | Returns given response headers. |
| /redirect/:n | 302 Redirects n times. |
| /redirect-to?url=foo | 302 Redirects to the foo URL. |
| /relative-redirect/:n | 302 Relative redirects n times. |
| /cookies | Returns cookie data. |
| /cookies/set?name=value | Sets one or more simple cookies. |
| /cookies/delete?name | Deletes one or more simple cookies. |
| /basic-auth/:user/:passwd | Challenges HTTPBasic Auth. |
| /hidden-basic-auth/:user/:passwd | 404'd BasicAuth. |
| /digest-auth/:qop/:user/:passwd | Challenges HTTP Digest Auth. |
| /stream/:n | Streams n – 100 lines. |
| /delay/:n | Delays responding for n – 10 seconds. |
| /drip | Drips data over a duration after an optional initial delay, then (optionally) returns with the given status code. |
| /range/:n | Streams n bytes, and allows specifying a Range header to select a subset of the data. Accepts a chunk_size and request duration parameter. |
| /html | Renders an HTML Page. |
| /robots.txt | Returns some robots.txt rules. |
| /deny | Denied by robots.txt file. |
| /cache | Returns 200 unless an If-Modified-Since or If-None-Match header is provided, when it returns a 304. |
| /cache/:n | Sets a Cache-Control header for n seconds. |
| /bytes/:n | Generates n random bytes of binary data, accepts optional seed integer parameter. |
| /stream-bytes/:n | Streams n random bytes of binary data, accepts optional seed and chunk_size integer parameters. |
| /links/:n | Returns page containing n HTML links. |
| /forms/post | HTML form that submits to /post |
| /xml | Returns some XML |
| /encoding/utf8 | Returns page containing UTF-8 data. |
简单例子
import requests
s = requests.Session()
print s.get('http://httpbin.org/ip').text
print s.get('http://httpbin.org/get').json()
print s.post('http://httpbin.org/post', {'key':'value'},headers={'user-agent':'LAOGAO'}).text
print s.get('http://httpbin.org/status/404').status_code
print s.get('http://httpbin.org/html').text
print s.get('http://httpbin.org/deny').text
技巧
httpbin给我们提供了很多HTTP基本的操作，如果你的APP组问你要接口，你手头又很忙，怎么办？当然是用httpbin按照接口文档先给他们快速写几个丢过去。
部署
httpbin使用flask编写，可以参考使用nginx + uWSGI运行flask程序，不过在此老高又学会了一种新的方法 -- 使用gunicorn运行flask。
gunicorn又是一个 Python WSGI HTTP Server for UNIX!
# 如果已经安装PIP，请忽略此步骤
cd ~ && wget -O - "https://bootstrap.pypa.io/get-pip.py" | python
# 安装httpbin
pip install httpbin
# 安装服务器软件gunicorn
pip install gunicorn
# 运行httpbin，在8000端口
gunicorn -b :8000 httpbin:app
# [2015-06-27 03:16:52 +0000] [18568] [INFO] Starting gunicorn 19.3.0
# [2015-06-27 03:16:52 +0000] [18568] [INFO] Listening at: http://0.0.0.0:8000 (18568)
# [2015-06-27 03:16:52 +0000] [18568] [INFO] Using worker: sync
# [2015-06-27 03:16:52 +0000] [18573] [INFO] Booting worker with pid: 18573
接下来访问你的IP:8000，不出意外，你就能看到与官网一样的功能了！
使用文档
使用PHPSTORM RESTful调试
在 Tools | Test RESTful 中可以找到Test RESTful工具，可以方便的调试接口。
[...]后端将示例接口返回数据写在文件里，接口直接返回静态文件数据。此种方式，由后端定义接口数据格式。另外，有一个开源的工具: httpbin可以用来提供接口返回指定格式的数据，中文介绍可见:https://blog.phpgao.com/how-to-httpbin.html。[...]
