Python session 不适用于多个请求

Question

我是Python新手，所以请原谅我的缺乏良心..

Requirement : Need to process a list of strings through a rest api call

问题:使用 Requests，我能够成功进行 api 调用并完成工作。使用请求没有任何问题，除了想研究使用 session 是否会加快我的处理速度，因为我在每个请求中传递身份验证。

跟踪了多个使用 session 的线索，但仍然收到 HTTP 400 - 错误请求。

引用:Python Requests and persistent sessions

这是我试图使其工作的代码，任何帮助都会非常有帮助:

import requests
from requests.auth import HTTPBasicAuth

with open('list.txt') as f:
    lines = f.read().splitlines()

s = requests.Session()
r = s.get("https://ucdeploy.domain.com/rest/state", auth=HTTPBasicAuth('username', 'password'))

if r:
    print("Logged in Successfully")
else:
    print("Login Failed ==> " + str(r))
    exit()

for cmp in lines:
    print("Processing - " + cmp.strip())
    payload = '{"name":"' + cmp.strip() + '","description":"","templateId":"141e248c-ca02-4f51-a873-c07acd5366cd",' \
                                          '"templateVersion":"","componentType":"STANDARD","sourceConfigPlugin":"",' \
                                          '"importAutomatically":"false","useVfs":"true","defaultVersionType":"FULL",' \
                                          '"importAgentType":"inherit","inheritSystemCleanup":"true",' \
                                          '"runVersionCreationProcess":"false","properties":{},"teamMappings":[{' \
                                          '"teamId":"bf3c4566-160b-4d79-b47e-5f2bbc1ffbb0"}]}'

    response = s.put("https://ucdeploy.domain.com/rest/deploy/component", data=payload)
    if response:
        print("Successfully Processed")
    else:
        print("Failed ==> " + str(response))
        exit()

输出:

Logged in Successfully
Processing - Component1
Failed ==> <Response [400]>

确定了有效负载格式的问题。

由于某种原因，下面的串联代码不起作用:

payload = '{"name":"' + cmp.strip() + '","description":"","templateId":"141e248c-ca02-4f51-a873-c07acd5366cd",' \
                                          '"templateVersion":"","componentType":"STANDARD","sourceConfigPlugin":"",' \
                                          '"importAutomatically":"false","useVfs":"true","defaultVersionType":"FULL",' \
                                          '"importAgentType":"inherit","inheritSystemCleanup":"true",' \
                                          '"runVersionCreationProcess":"false","properties":{},"teamMappings":[{' \
                                          '"teamId":"bf3c4566-160b-4d79-b47e-5f2bbc1ffbb0"}]}'

使用以下内容更新了有效负载串联并且它有效:

componentname = '{"name":"' + cmp.strip()
payload = componentname + '","description":"","templateId":"141e248c-ca02-4f51-a873-c07acd5366cd",' \
                              '"templateVersion":"","componentType":"STANDARD","sourceConfigPlugin":"",' \
                              '"importAutomatically":"false","useVfs":"true","defaultVersionType":"FULL",' \
                              '"importAgentType":"inherit","inheritSystemCleanup":"true",' \
                              '"runVersionCreationProcess":"false","properties":{},"teamMappings":[{' \
                              '"teamId":"bf3c4566-160b-4d79-b47e-5f2bbc1ffbb0"}]}'

我希望这对某人有帮助。
