Python interface Automation 14-multipart/form-data uploading images

Objective
When submitting the form operation, often encounter picture upload operation, picture upload is a separate interface, this article takes Zen Road as an example, describes how to upload pictures

First, upload interface

1. To submit a bug on Zen road, for example, when selecting a picture, click the OK button to upload the image.

2. Grab the packet with fiddler and look at the caught interface, the following interface is Multipart/form-data
-Content-type:multipart/form-data
-The body parameter is this format:

-----------------------------22165374713946
Content-disposition:form-data; Name= "Localurl"

Yoyoketang.png
-----------------------------22165374713946
Content-disposition:form-data; Name= "Imgfile"; Filename= "Yoyoketang.png"
Content-type:image/png

Second, login first

1. Because uploading pictures is done after login, this need to rely on user login

1 ```2 #Coding:utf-83 ImportRequests4 5Base ='http://127.0.0.1:81/'  #the server address of Zen Road6 7Loginurl = base+"/zentao/user-login.html"8 9h = {Ten     "user-agent":"mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) gecko/20100101 firefox/44.0", One     "Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", A     "Accept-language":"zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3", -     "accept-encoding":"gzip, deflate", -     "Referer":"http://127.0.0.1/zentao/user-login.html", the     #"Cookie": # Do not use cookies until the head is logged in, as cookies are kept logged in -     "Connection":"keep-alive", -     "Content-type":"application/x-www-form-urlencoded", -     } +  -BODY = {" Account":"Admin", +         "Password":"e10adc3949ba59abbe56e057f20f883e", A         "keeplogin[]":" on", at         "Referer":"http://127.0.0.1/zentao/my/" -         } -  -s = requests.session ()#hold Session -R = S.post (loginurl, Data=body, headers=h) - PrintR.content#print results See location= ' http://127.0.0.1/zentao/my/' instructions login succeeded in```

Third, upload pictures

1. Upload the image in the following format:
-----------------------------22165374713946
Content-disposition:form-data; Name= "Localurl"

Yoyoketang.png
-----------------------------22165374713946
Content-disposition:form-data; Name= "Imgfile"; Filename= "Yoyoketang.png"
Content-type:image/png

2. Written in dictionary format, key corresponds to Name= "Imgfile" here name corresponding value

3.value inside is a tuple ()
-the first parameter is the corresponding value after filename=, no write None
-The second is the above value "" "Yoyoketang.png", or the binary stream opened by the file open
-The third is the content-type corresponding type, such as: "Image/png"

F ={
"Localurl": (None, "1.png"),
"Imgfile": ("1.png", Open ("D:\\1.png", "RB"), "Image/png")
}

Iv. Verifying the success of the upload
1. Get the post-upload address and put it in the browser's address bar request to see if the image you just uploaded
