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

```

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",

"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

import requests

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

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

h = {

"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0",

"Accept-Encoding": "gzip, deflate",

"Referer": base+"/zentao/user-login.html",

# "Cookie": # 头部没登录前不用传cookie，因为这里cookie就是保持登录的

"Connection": "keep-alive",

"Content-Type": "application/x-www-form-urlencoded",

}

body = {"account":"admin",

"password":"e10adc3949ba59abbe56e057f20f883e",

"keepLogin[]":"on",

"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

url1 = base+"/zentao/bug-create-1-0-moduleID=0.html"

f = {

"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和2",

"severity": "3",

"pri": "0",

"steps": '
