我正在使用curl和pycurl连接到安全的第三方api,当我使用pycurl时,我从服务器返回了身份验证错误,但是当我在命令行上使用curl并完成了同样的工作时.我都将其设置为详细模式,并且在请求中看到了一些差异,但是我似乎无法弄清楚错误是什么.

他们似乎使用了不同的加密方法,也许是问题所在吗？如果有人对尝试使用pycurl有不同的选择的想法,或者对重新编译pycurl使其像curl一样起作用的建议,那将很棒.谢谢.

这是我的pycurl设置,仅供参考：

    buffer = cStringIO.StringIO()

    curl = pycurl.Curl()
    curl.setopt(pycurl.VERBOSE,1) 
    curl.setopt(pycurl.POST, 1)
    curl.setopt(pycurl.POSTFIELDS, post_data)
    curl.setopt(pycurl.TIMEOUT_MS, self.HTTP_TIMEOUT)
    curl.setopt(pycurl.URL, url)
    curl.setopt(pycurl.FOLLOWLOCATION, self.HTTP_FOLLOW_REDIRECTS)
    curl.setopt(pycurl.MAXREDIRS, self.HTTP_MAX_REDIRECTS)
    curl.setopt(pycurl.WRITEFUNCTION, buffer.write)
    curl.setopt(pycurl.NOSIGNAL, 1)
    curl.setopt(pycurl.SSLCERT, self.path_to_ssl_cert)

    curl.setopt(pycurl.SSL_VERIFYPEER, 0)

    # 1/0

    try:
        curl.perform()

…

哦,最后一件事：我正在使用的相同python脚本可在Mac笔记本电脑上使用,但不适用于我要设置的ubuntu服务器.

解决方法:

Ubuntu pycurl使用GnuTLS,而ubuntu curl命令行使用OpenSSL.
有差异,例如支持的证书格式.

我无法理解ubuntu开发人员/打包人员做出的这一决定.我偶然发现了这个,无法解决,幸运的是,除了ubuntu以外,还有其他发行版:-)
