如何用python通过burp发送curl的请求？

我正试图通过burp路由某些请求。这些将是HTTPS请求

我已经正确地安装了burp，并将 cacert.der 证书放在了代码所在的当前工作目录中。我已经看了 https://curl.haxx.se/libcurl/c/curl_easy_setopt.html ，但不能让它工作。

这是我目前用来尝试的代码

@classmethod
def CURLpageThroughBurp(cls, encodedURL):
    buffer = BytesIO()
    c = pycurl.Curl()
    c.setopt(c.URL, str(encodedURL))
    c.setopt(c.CAINFO, certifi.where())
    c.setopt(c.PROXY, '127.0.0.1')
    c.setopt(c.PROXYPORT, 8080)
    c.setopt(c.PROXY_SSLCERT, "cacert.der")
    c.setopt(c.PROXY_SSLCERTTYPE, "DER")
    c.setopt(c.FOLLOWLOCATION, True)
    ##c.setopt(c.PROXYTYPE, c.PROXYTYPE_SOCKS5_HOSTNAME)
    c.setopt(c.WRITEDATA, buffer)
    c.perform()
    c.close()
    webpage = buffer.getvalue()
    return webpage
Here's the error I receive:
File "randomcode,py", line 111 c.perform()
pycurl.error: (60, 'SSL certificate problem: self signed certificate in certificate chain')
