python3 实现 get 和 post 请求

用 python3 写脚本发送 get 或 post 请求已经不下一次了，可是每次写都不能随心顺手，总得要百度一下，而后照搬过来，测试才能使用，这里记下使用 demo，方便之后使用。

• get 请求

#获取git仓库信息
def get_git_info():
params = parse.urlencode({"repo":repo,"git_url":git_url})
response = request.urlopen(conf.git_info_url + '?%s' % params)
result = json.loads(response.read().decode('utf-8'))
global git_info
if result['status']:
    print('获取仓库信息成功')
    git_info = result['data']
    global code_run_path
    if code_run_path == '':
        code_run_path = git_info['code_run_path'].rstrip('/')
else:
    msg = result['msg']
    print(msg)
    raise Exception('获取git仓库信息失败')
return git_info复制代码

• 固然，这里前提是要导入模块 from urllib import parse,request，parse.urlencode({"repo":repo,"git_url":git_url}) 对参数进行编码，request.urlopen(conf.git_info_url + '?%s' % params) 发送拼接请求，response.read().decode('utf-8') 读取返回内容并用 utf-8 编码方式解析出来
• post 请求

def log_release(success_servers,fail_servers,error_msg,status):
deploy_file = source_dir + '/post-deploy-script.sh'
deploy_script=''
if os.path.isfile(deploy_file):
    with open(deploy_file,'r') as f:
        deploy_script = f.read()
exclude_file = source_dir + '/.deploy-exclude.list'
exclude_content = ''
if os.path.isfile(exclude_file):
    with open(exclude_file, 'r') as f:
        exclude_content = f.read()

deploy_version_log = get_version()
data = {"env":env,"mode":mode,"git_url":git_url,"source_dir":source_dir,"is_sync_delete":str(is_sync_delete),"repo_dir":repo,
        "code_run_path":code_run_path,"success_servers":success_servers,"fail_servers":fail_servers,"error_msg":error_msg,
        "status":str(status),"deploy_script":deploy_script,"deploy_version_log":deploy_version_log,"exclude_content":exclude_content}

text_data = json.dumps(data)
text_data = bytes(text_data,'utf-8')
response = request.Request(conf.log_release_url, text_data)
res = request.urlopen(response)复制代码

定义 json 参数

data =
{"env":env,"mode":mode,"git_url":git_url,"source_dir":source_dir,"is_sync_delete":str(is_sync_del
ete),"repo_dir":repo,

"code_run_path":code_run_path,"success_servers":success_servers,"fail_servers":fail_servers,"erro r_msg":error_msg,

"status":str(status),"deploy_script":deploy_script,"deploy_version_log":deploy_version_log,"exclu de_content":exclude_content}复制代码

将 json 转为 字符串text_data = json.dumps(data)

将参数转化字节流text_data = bytes(text_data,'utf-8')

发送请求response = request.Request(conf.log_release_url, text_data) res = request.urlopen(response)

这里须要注意的是，post 过去的数据若是是 php 接收的话须要 使用如下方式接收并处理

$data = file_get_contents('php://input');
$data = json_decode($data, true);复制代码

• 笔者在这里踩过几回坑了，直接用框架的 post 取出来的是整个字符串，用 json 又解析不出来参数数组
