Question

我有一个应用程序，我在其中引用外部库。在从这个库中的对象类型调用一个特定方法时，我的一些客户端遇到问题，因为他们在这个库的版本中没有这个方法。我试图捕获此异常并正确地向用户报告。所以我将调用包装在try / catch块中，但这并没有抓住它：

try
{
    cell.setRowspan(rowSpan);
}
catch (Exception  e)
{
    Throwable throwable = e.getCause();
    throw new Exception(throwable);
}

当我尝试调试问题时，eclipse只是打开了java.lang.reflect.InvocationTargetException clas。它不会进入catch块。我能在这里做些什么来正确地解决这个问题？

import requests
import json

session = requests.Session()

loginUrl = "https://wedgfl.aquahawk.us/login"
loginHeaders = {
        "Host": "wedgfl.aquahawk.us",
        "Connection: keep-alive",
        "Accept": "application/json",
        "Origin": "https://wedgfl.aquahawk.us",
        "X-Requested-With": "XMLHttpRequest",

}

loginData = {
    "username":"myemail@domain.tld",
    "password":"MySecretPassword"

}

#Data is posted as Json Data using json.dumps
loginResponse = session.post(loginUrl, data=json.dumps(loginData), headers=loginHeaders)
#If the above does not work try without json.dumps
loginResponse = session.post(loginUrl, data=loginData, headers=loginHeaders)
print(loginResponse)   #should print 200

#check if logged in 

verify = session.get("https://wedgfl.aquahawk.us/")
print(verify.text)
