Pan*_*hal 9 authentication curl login stackexchange-api
我正在尝试以编程方式登录我的stackoverflow.com帐户.我试着像下面那样做一个卷曲,但它要求内容长度:
$ curl -X POST --user abc@gmail.com:abc https://stackoverflow.com/users/login -v

我也没试过POST.它返回200但没有登录.

我怎么能做到这一点？
除此之外，使用 api.stackexchange.com/docs/authentication 将是最好的解决方案，上述curl语句的问题是您向服务器发送了一个没有正文的http post。所以你应该添加类似的内容：
-d "user=value1&passwd=value2"
其中 user/passwd 应该是此处登录对话框的字段名称 - 也可能登录表单包含一些隐藏字段......所以您应该首先分析它。另请记住，您让curl 将cookie 写入文件中，以便您可以在以后的curl 调用中使用它们。
