尝试在接受100-Continue标头后发送Python HTTPConnection内容

• ->；建立连接
• ->；发送数据，包括"；Expect：100-Continue&Quot；Header，但不包括JSON正文
• <；-接收&q；100-继续(&Q)
• ->；使用相同的连接，发送请求的JSON正文
• <；-在带有其他信息的JSON响应中接收200 OK消息

以下是代码的当前状态，删除了我的10多个其他尝试解决方法的注释残留物：

我考虑过改用请求库，但我无法让它使用我的本地证书包来接受站点的证书。我有一个带有加密密钥的完整链，我确实对其进行了解密，但仍然遇到来自请求的持续的SSL_VERIFY错误。如果您有解决我当前请求问题的建议，我也很乐意沿着这条路走下去。

如何使用HTTPLib或请求(或任何其他库)来实现我需要的目标？

推荐答案

如果将来有人遇到此问题，我最终使用了一些杂乱无章的方法来解决它。我尝试过HTTPLib、请求和URLLib3，它们都不能处理100-Continue标头，所以.我刚刚通过subprocess.run()函数在Curl周围编写了一个Python包装器，如下所示：

def sendReq(upFile):
    sendFile=f"file=@{upFile}"

    completed = subprocess.run([
    curlPath,
    '--cert',
    args.cert,
    '--key',
    args.key,
    targetHost,
    '-H',
    'accept: application/json',
    '-H',
    'Content-Type: multipart/form-data',
    '-H',
    'Expect: 100-continue',
    '-F',
    sendFile,
     '-s'
    ], stdout=subprocess.PIPE, universal_newlines=True)

    return completed.stdout
