OpenSSL.SSL.syscaller错误：（10054，'WSAECONNRESET'）在获取对ArcGIS API的请求期间

Question

版本

Python                3.7.0

pyOpenSSL             18.0.0
requests              2.19.1
requests-futures      0.9.7
urllib3               1.23

在使用Python时，我无法从ArcGIS restapi收到完整的响应。我可以通过Chrome导航到URL，也可以在Postman中发出GET请求。上面的链接是一个成功的GET请求的示例，其中包含我期望的JSON响应。我尝试过使用requests、urllib和socket编写请求。显然，这两个请求和套接字都在recv\u into时失败。当运行下面的代码时，在我得到WSAECONNRESET错误之前，我只收到两个块。如果我在geometry设置为false的情况下发出请求，响应会小得多，并且返回时不会出现问题。我不知道为什么连接只在Python中关闭，需要一些帮助来修复它，或者使用其他方法来进行查询。在

谢谢！在

我在使用内部服务器时遇到了类似的问题。从ssl.1.1降到了openi.1.1。在

或者，一个更简单的解决方案是不使用OpenSSL。在导入请求之后，将立即使用callrequests.packages.urllib3.contrib.pyopenssl.extract_from_urllib3()和python的stdlib SSL实现来代替OpenSSL。在

这肯定是个bug，但我不确定是openssl、pyopenssl还是糟糕的服务器配置。在
