python locust接口性能测试HTTPS网站报错：Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certi

问题描述：

测试HTTPS SSL 协议的网站接口，用Python Locust模块，不论POST还是GET都提示错误：

SSLError
Max retries exceeded with url: /action.php?m=upload 
(Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)'),))",),)

后面查官网locust.io,终于找到解决方法：https://docs.locust.io/en/latest/api.html

request ( method,  url,  name=None,  catch_response=False,  **kwargs )

Constructs and sends a requests.Request. Returns requests.Response object.

Parameters:

method – method for the new Request object. url – URL for the new Request object. name – (optional) An argument that can be specified to use as label in Locust’s statistics instead of the URL path. This can be used to group different URL’s that are requested into a single entry in Locust’s statistics. catch_response – (optional) Boolean argument that, if set, can be used to make a request return a context manager to work as argument to a with statement. This will allow the request to be marked as a fail based on the content of the response, even if the response code is ok (2xx). The opposite also works, one can use catch_response to catch a request and then mark it as successful even if the response code was not (i.e 500 or 404). params – (optional) Dictionary or bytes to be sent in the query string for the Request. data – (optional) Dictionary or bytes to send in the body of the Request. headers – (optional) Dictionary of HTTP Headers to send with the Request. cookies – (optional) Dict or CookieJar object to send with the Request. files – (optional) Dictionary of 'filename': file-like-objects for multipart encoding upload. auth – (optional) Auth tuple or callable to enable Basic/Digest/Custom HTTP Auth. timeout (float or tuple) – (optional) How long to wait for the server to send data before giving up, as a float, or a (connect timeout, read timeout) tuple. allow_redirects (bool) – (optional) Set to True by default. proxies – (optional) Dictionary mapping protocol to the URL of the proxy. stream – (optional) whether to immediately download the response content. Defaults to False. verify – (optional) if True, the SSL cert will be verified. A CA_BUNDLE path can also be provided. cert – (optional) if String, path to ssl client cert file (.pem). If Tuple, (‘cert’, ‘key’) pair.

利用verify参数，直接在POST/GET请求添加verify = False参数，搞定，

这是HTTPS网站所做的SSL证书认证，默认是True的，设置为False之后对测试没有影响；

当然如果知道证书的路径，应该也可以用cert设置.pem文件的路径，也可以解决
