python接口自动化18-multipart/form-data上传多个附件（form表单multipart/form-data）

前言

reuqests上传一张图片到服务器，前面已经介绍过了，那么如何在提交BUG的时候，上传附件呢？

上传附件的时候，文件的name参数名称是一样的，python里面key是不可以重复的，又如何处理参数名称相同的情况？

上传附件

1.以禅道提交BUG的时候上传附件为例

2.fiddler抓包看请求参数，查看到文件上传的参数如下

上传一个附件

1.之前学了一篇ultipart/form-data文件上传，然后学了一篇ultipart/form-data表单提交，这里文件上传，就是把两篇的知识点加起来

2.把参数分开，表单的数据用data提交，文件附件用files提交

# -----------------------前面先登录步骤省略了-------------# 提交bug, 带上附件url1 = host+"/zentao/bug-create-1-0-moduleID=0.html"d= { "product": "1", "module": "0", "project": "", "openedBuild[]": "trunk", "assignedTo": "admin", "type": "codeerror", "os": "all", "browser": "all", "color": "", "title": "yoyoketang-这是一个带附件的1", "severity": "3", "pri": "0", "steps": '

', "story": "0", "task": "0", "mailto[]": "", "keywords": "", # "files[]": ("1.png", open("d:\\1.png", "rb"), "image/png"), # "labels[]": "tu1", "uid": "5a2955c884f98", "case": "0", "caseVersion": "0", "result": "0", "testtask": "0" }file = { "files[]": ("1.png", open("d:\\1.png", "rb"), "image/png"), "labels[]": "tu1", }r = s.post(url1, data=d, files=file) # 分开传print r.content

传多个附件

1.传多个文件的时候如下，这两个参数的name都是一样的，如果用字典去传key值，很显然python的key值是不能重复的

Content-Disposition: form-data; name="files[]"; filename="1.png"

Content-Type: image/png

Content-Disposition: form-data; name="files[]"; filename="2.png"

Content-Type: image/png

2.这时候需要换个格式，传list数据

# file = {# "files[]": ("1.png", open("d:\\1.png", "rb"), "image/png"),# "labels[]": "tu1",# }#-------------多个文件用list类型------------file = [ ("files[]", ("2.png", open("d:\\1.png", "rb"), "image/png")), ("labels[]", "tu1"), ("files[]", ("2.png", open("d:\\2.png", "rb"), "image/png")), ("labels[]", "tu2"), ]

3.上传之后，查看禅道上是可以提交成功的

参考代码
