问题 I've written a simple HTTP client using aiohttp and I'm trying to test it by patching aiohttp.ClientSession and aiohttp.ClientResponse . However, it appears as though the unittest.mock.patch decorator is not respecting my asynchronous code. At a guess, I would say it's some kind of namespacing mismatch. Here's a minimal example: from aiohttp import ClientSession async def is_ok(url:str) -> bool: async with ClientSession() as session: async with session.request("GET", url) as response: return

问题 I have a picture were I want to change all white-ish pixels to grey, but only for a certain area of the image. Example picture, I just want to change the picture outside of the red rectangle, without changing the image within the red rectangle: I already have the general code, which was part of someone elses Stackoverflow question, that changes the colour of every white pixel instead of only just the one outside of an area. image = cv.imread("meme 2.jpg") hsv = cv.cvtColor(image, cv.COLOR

问题 I have implemented Netflix OSS Hystrix in one of my Spring boot application. And configured some properties for the HystrixCommand. But how can I verify that those properties are really used by HystrixCommand. For example, hystrix.threadpool.default.maxQueueSize=12 hystrix.threadpool.default.keepAliveTimeMinute=2 hystrix.command.default.execution.isolation.strategy=SEMAPHORE How can I see that these properties are applied to HystrixCommand? Is there any way I can enable debug level logging

问题 I have a problem with my code, even though it hasn't been modified in any way. It just suddenly threw this message. As you can see on the left, that they are all in the correct package, and have correct names. What can I do to fix this problem? 回答1: Clear the cache to fix it. In Windows, cache is located at: C:\Users\username\AppData\Local\NetBeans\... On Linux, cache is at: /home/username/.cache/netbeans/... After clearing the cache restart netbeans. 回答2: If clearing the cache still doesn't

问题 I'm trying to make my own Tabs component, so that I can use tabs in my app. However I seem to be having issues trying to extract the child components I need by type. import React from 'react' export class Tabs extends React.Component { render() { let children = this.props.children let tablinks = React.Children.map(children, x => { console.log(x.type.displayName) // Always undefined if (x.type.displayName == 'Tab Link') { return x } }) return ( <div className="tabs"></div> ) } } export class

问题 I'm communicating with a webservice in SOAP with php. Here's my code : $data = array('name' => 'test', 'age' => 20); $WDSL = 'http://xxx.xxxxx.xxx/wdsl.ibs?wsdl'; $SOAP = new SoapClient($WDSL, array('trace' => true)); $RESULT = $SOAP->__soapCall('Some_Service', $data); For some reason, the XML is wrong : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:Some_Crap"><SOAP-ENV:Body><ns1:Some_Service/><param1>test<
