在做接口测试的时候我们会遇到过需要填写表单的形式，那么如何通过requests进行请求呢？ 这里需要引入新的python的第3方库requests-toolbelt requests-toolbelt1、安装 pip install requests-toolbelt
源码： 这里包含了许多方法，我们慢慢的进行了解 [url=]![]() [/url]
# -*- coding: utf-8 -*-"""requests-toolbelt=================See http://toolbelt.rtfd.org/ for documentation:copyright: (c) 2014 by Ian Cordasco and Cory Benfield:license: Apache v2.0, see LICENSE for more details"""from .adapters import SSLAdapter, SourceAddressAdapterfrom .auth.guess import GuessAuthfrom .multipart import ( MultipartEncoder, MultipartEncoderMonitor, MultipartDecoder, ImproperBodyPartContentException, NonMultipartContentTypeException )from .streaming_iterator import StreamingIteratorfrom .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__',][url=]![]() [/url]
这里我们会用到MultipartEncoder方法 MultipartEncoder上传文件用法[url=]![]() [/url]
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})[url=]![]() [/url]
MultipartEncoder填写表格用法[url=]![]() [/url]
from requests_toolbelt import MultipartEncoderimport requestsm = MultipartEncoder(fields={'field0': 'value', 'field1': 'value'})r = requests.post('http://httpbin.org/post', data=m, headers={'Content-Type': m.content_type})[url=]![]() [/url]
小试牛刀这里安静通过举个小栗子来更加理解requests-toolbelt的用法，这里通过禅道提bug的接口 1、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 通过抓包数据分析，可以看出来这是个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需要的内容）。 2、导入requests-toobelt使用MultipartEncoder方法 参照源码方式，一个个参数进行添加，然后修改标题和修改bug内容 [url=]![]() [/url]

3、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
通过一个小栗子让我们熟悉了requests-toolbelt的用法，当然不仅仅只有这一种方法，其他的方法小伙伴们可以自己摸索下，自己尝试写下
