python接口自动化16-multipart/form-data上传多个附件

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？ 一、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

二、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": '[步骤] 1、第一步点 2、第二步点 3、点三步点 [结果] <img src="data/upload/1/201712/072254170557cdn.png" alt="" /> [期望]', "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 ``` 三、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

四、参考代码


```
# coding:utf-8

base = 'http://127.0.0.1:81'  # 禅道的服务器地址

loginUrl = base+"/zentao/user-login.html"

        "referer":base+"/zentao/my/"
        }

s = requests.session()  # 保持会话
r = s.post(loginUrl, data=body, headers=h)
print r.content  # 打印结果看到location='http://127.0.0.1/zentao/my/'说明登录成功了

# 提交bug, 带上附件

    }

# file = {

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

    ]

r = s.post(url1, data=f, files=file)
print r.content
