python接口自动化15-multipart/form-data表单提交

前言

multipart/form-data这种格式官方文档给的参考案例比较简单，实际情况中遇到会比较复杂，本篇讲解multipart/form-data的表单如何提交，非图片上传

一、 禅道提交bug

1.以禅道提交bug为参考案例,手动操作一次提交bug，抓包查看Content-Type: multipart/form-data

2.在WebForms里面查看参数详情

二、参数填写

1.注意了，这里的参数对应为字典格式，字典的key对应WebForms里查看的name="这里的参数"，value对应WebForms查看的value值

```
f = {
    "product": "1",
    "module": "0",
    "project": "",
    "openedBuild[]": "trunk",
    "assignedTo": "admin",
    "type": "codeerror",
    "os": "all",
    "browser": "all",
    "color": "",
    "title": "yoyoketang-这是一个bug描述1122",
    "severity": "3",
    "pri": "0",
    "steps": '<p>[步骤]</p>\
            <p>1、第一步点</p>\
            <p>2、第二步点</p>\
            <p>3、点三步点</p>\
            <p>[结果]</p>\
            <p><img src="data/upload/1/201712/072254170557cdn.png" alt="" /></p>\
            <p>[期望]</p>',
    "story": "0",
    "task": "0",
    "mailto[]": "",
    "keywords": "",
    "files[]": "",
    "labels[]": "",
    "uid": "5a2955c884f98",
    "case": "0",
    "caseVersion": "0",
    "result": "0",
    "testtask": "0"
    }
```
2.如果有图片上传，这里<img src="data/upload/1/201712/072254170557cdn.png" 这个图片地址就是上一篇讲到的上传图片接口返回的图片地址（相对路径）

三、参考代码

1.multipart/form-data这里传的是data参数（上一篇文件上传是files参数）
2.这里头部不要加Content-Type: multipart/form-data这个参数，会报错

```
# coding:utf-8

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

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

        }
