2、CURL请求

curl -X POST 
  'http://127.0.0.1:5000/test?params=test' 
  -H 'cache-control: no-cache'

3、python代码

request.values.get('params')
request.args.get('params')

二、参数在header中
1、HTTP请求

POST /test HTTP/1.1
Host: 127.0.0.1:5000
token: this is a token
cache-control: no-cache

2、CURL请求

curl -X POST

  -H 'cache-control: no-cache' 
  -H 'token: this is a token'

3、python代码

request.headers.get('token')

三、body下的form-data
1、HTTP请求

  -H 'cache-control: no-cache' 
  -H 'content-type: multipart/form-data;'
  -F key=value 
  -F 'file=@C:Usersx1cDesktop3.jpg'

3、python代码

request.form.get('key') 或者 request.form['key']
request.files
# 结果
value
ImmutableMultiDict([('file', <FileStorage: '3.jpg' ('image/jpeg')>)])

文件类型

image.png

jmeter_report = request.files['file']
dst = os.path.join(os.path.dirname(__file__), jmeter_report.name)
jmeter_report.save(dst)
with open(dst, 'r') as file:
        #如果是json类型的文件可以这样
        file_all = json.load(file)
        #非json类型的文件就按照普通文件处理
        for line in file:
            line=line.strip()
request_parms = {}
request_parms['sampleCount'] = file_all.get('Total', {}).get('sampleCount', '')
