requests---requests请求表单

 　　在作接口测试的时候咱们会遇到过须要填写表单的形式，那么如何经过requests进行请求呢？ 这里须要引入新的python的第3方库requests-toolbelt

requests-toolbelt

一、安装

pip install requests-toolbelt

官方文档：https://pypi.org/project/requests-toolbelt/

源码：

这里包含了许多方法，咱们慢慢的进行了解

"""

from .adapters import SSLAdapter, SourceAddressAdapter
from .auth.guess import GuessAuth
from .multipart import (
    MultipartEncoder, MultipartEncoderMonitor, MultipartDecoder,
    ImproperBodyPartContentException, NonMultipartContentTypeException
    )
from .streaming_iterator import StreamingIterator
from .utils.user_agent import user_agent

__title__ = 'requests-toolbelt'
__authors__ = 'Ian Cordasco, Cory Benfield'
__license__ = 'Apache v2.0'
__copyright__ = 'Copyright 2014 Ian Cordasco, Cory Benfield'
__version__ = '0.9.1'
__version_info__ = tuple(int(i) for i in __version__.split('.'))

__all__ = [
    'GuessAuth', 'MultipartEncoder', 'MultipartEncoderMonitor',
    'MultipartDecoder', 'SSLAdapter', 'SourceAddressAdapter',
    'StreamingIterator', 'user_agent', 'ImproperBodyPartContentException',
    'NonMultipartContentTypeException', '__title__', '__authors__',
    '__license__', '__copyright__', '__version__', '__version_info__',
]

这里咱们会用到MultipartEncoder方法

MultipartEncoder上传文件用法

  import requests
  from requests_toolbelt import MultipartEncoder

  encoder = MultipartEncoder({'field': 'value',
                                    'other_field', 'other_value'})
  r = requests.post('https://httpbin.org/post', data=encoder,
                          headers={'Content-Type': encoder.content_type})

MultipartEncoder填写表格用法

from requests_toolbelt import MultipartEncoder
import requests

m = MultipartEncoder(fields={'field0': 'value', 'field1': 'value'})

r = requests.post('http://httpbin.org/post', data=m,
                  headers={'Content-Type': m.content_type})

小试牛刀

这里安静经过举个小栗子来更加理解requests-toolbelt的用法，这里经过禅道提bug的接口

一、抓取禅道提bug的接口，分析参数数据

填写bug列表，打开Fiddler进行抓包分析数据

经过抓包数据分析，能够看出来这是个multipart/form-data的数据类型，下面是填写的参数信息，老规矩，一个个写下来（这里不清楚那个是必填项或者是须要的内容）。

二、导入requests-toobelt使用MultipartEncoder方法

参照源码方式，一个个参数进行添加，而后修改标题和修改bug内容

# coding:utf-8
import requests
from requests_toolbelt import MultipartEncoder
# 接口地址
url = 'http://demo.zentao.net/bug-create-39-0-moduleID=0.html'
# 请求头
headers = {
    "User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36",
    "Cookie":"__cfduid=dcc14bd65a47b718842d4b412e2d517721545125741; Hm_lvt_731bb611021e8720f1fc3035dfd2a44f=1572415581; Hm_lpvt_731bb611021e8720f1fc3035dfd2a44f=1572415585; zentaosid=n6m4ua9k7b2c0hte58mqfi2lc0; lang=zh-cn; device=desktop; theme=default; UM_distinctid=16e1b4fca6c56a-0522f3f1a973da-5f123917-100200-16e1b4fca6d67f; CNZZDATA4553360=cnzz_eid%3D557018590-1572412770-null%26ntime%3D1572412770; lastProduct=39; windowWidth=1366; windowHeight=625; preBranch=0; preProductID=39; bugModule=0; qaBugOrder=id_desc"
}
# 请求参数信息
data = MultipartEncoder(
    fields=[
        ('product',"40"),
        ('branch','0'),
        ('module','0'),
        ('project','448'),
        ('openedBuild[]','trunk'),
        ('assignedTo',''),
        ('deadline',''),
        ('type','codeerror'),
        ('os','windows'),    # 操做系统
        ('browser','all'),    # 浏览器
        ('title','这是bug的名称'),
        ('color',''),
        ('severity','3'),   # 严重级
        ('pri','3'),    # 优先级
        ('steps','<p>[步骤]</p>\n<p>测试步骤第一步</p>\n<br />\n<p>[结果]</p>这里测试步骤第2步\n<br />\n<p>[指望]</p>\n<br />'),
        ('story',''),
        ('task',''),
        ('oldTaskID','0'),
        ('mailto[]','dev1'),
        ('contactListMenu',''),
        ('keywords',''),
        ('status','active'),
        ('labels[]',''),
        ('files[]',''),
        ('uid','5db92b80efe7w'),
        ('case','0'),
        ('caseVersion','0'),
        ('caseVersion','0'),
        ('result','0'),
        ('testtask','0'),
            ],
    )
r = requests.post(url,headers={'Content-Type': data.content_type},data=data)

三、查看是否请求成功

具体的应该去数据库里看看数据有没有添加成功，这里安静模拟的接口，直接查看页面发现已经添加成功了

 

 

经过一个小栗子让咱们熟悉了requests-toolbelt的用法，固然不单单只有这一种方法，其余的方法小伙伴们能够本身摸索下，本身尝试写下
