全部问题(coding)

父组件：

<script>
    import Child from "./Child.svelte"
    import { onMount } from "svelte";
    import apireq from "./api.js";
    
    let items = $state.raw([]);

    let splitItems = $derived(items.splice(0, 5));

    onMount(() => {
        apireq().then(v => items = v)
    })
</script>
<h1>item count in parent {items.length}</h1>
<Child items={splitItems} />

子组件

<script>
  let props = $props();
  let { items} = props;
</script>

item count in child:
<div>{items.length}</div>

api 请求后子组件不会更新..仍然显示 0 计数父级确实更新。

我尝试了和$state。$state.raw但我不希望完全反应，因为它是一个很大的数组，而分配时的反应应该足够了

这在 svelte 4 中曾经非常简单，但在 5 中没有任何效果如预期 :(

@Autowired 不起作用，我们不知道原因。服务和控制器位于不同的模块和包中，但我们认为这并不重要。我们可以手动实例化服务，这样控制器模块就能够“看到”公共模块。

运行该应用程序会导致以下错误：

Parameter 0 of constructor in com.xx.campaign_api.controller.MyController required a bean of type 'com.xx.campaign.common.service.MyService' that could not be found.

我们有一个多模块 spring boot 3.4.2 项目，其 pom 如下：

<project xxx
    <groupId>org.springframework</groupId>
    <artifactId>our-service</artifactId>
    <version>0.1.0</version>
    <packaging>pom</packaging>

    <modules>
        <module>campaign-common</module>
        <module>campaign-api</module>
        <module>campaign-schedule</module>
    </modules>
</project>

在 api 模块中我们有一个像这样的休息控制器：

package com.xx.campaign_api.controller;
import com.xx.campaign.common.service.MyService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    private MyService testService;

    @Autowired
    public MyController(MyService testService) {  // THIS LINE IS FAILING
        this.testService = testService;
    }

    @GetMapping("/test")
    public String test() {
    return testService.test();
    }
}

该服务如下所示：

package com.xxx.campaign.common.service;
import org.springframework.stereotype.Service;

@Service
public class MyServiceImpl implements MyService {
    @Override
    public String test() {
        return "test3";
    }
}

package com.xxx.campaign.common.service;
public interface MyService {
    public String test();
}

主要类如下所示：

package com.xx.campaign_api;
@SpringBootApplication
public class CampaignApiApplication {
    public static void main(String[] args) {
        SpringApplication.run(CampaignApiApplication.class, args);
    }
}

在控制器模块的 pom 中，我们有：

    <dependency>
        <groupId>xx</groupId>
        <artifactId>campaign-common</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <scope>compile</scope>
    </dependency>

我也尝试过这个：

package com.xx.campaign_api.controller
@SpringBootApplication(scanBasePackages = "com.xx")
@RestController
public class GaController {

    private MyService myService;

    @Autowired
    public GaController(MyService myService) {  // THIS LINE IS FAILING
        this.myService = myService;
    }

但该应用程序无法启动并出现以下错误：

Web application could not be started as there was no org.springframework.boot.web.servlet.server.ServletWebServerFactory bean defined in the context.

我需要在与机器人交互时检查该帐户是否是新帐户。

我能够获得用户加入公会的时间信息，但是这些信息还不够。

member.getJoinTime();

我试图获取用户对象，但没有找到任何合适的方法。

我尝试使用 pyinstall 将 TKinter 脚本编译为 .exe 文件，但当我打开 .exe 文件时，它显示错误。我的 TKinter 脚本有线程。以下是显示 speedtest.py 中未处理的异常的堆栈跟踪

Traceback (most recent call last):
  File "speedtest.py", line 156, in <module>
ModuleNotFoundError: No module named '__builtin__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "Speedtest.py", line 3, in <module>
    from speedtest_cli import Speedtest
  File "<frozen importlib._bootstrap>", line 1360, in _find_and_load

AttributeError: 'NoneType' object has no attribute 'fileno'

这是我用于编译的代码：

process = subprocess.Popen(
    r'pyinstaller.exe --onefile --noconsole --distpath D:\PythonProjects\Speedtest Speedtest.py',
    stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE,
    shell=True)

output, error = process.communicate()

if error:
    print(error.decode())

if output:
    print(output.decode())

我试过：

• 将 --noconsole 更改为 --windowed
• 删除stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE

删除 --noconsole 不是一个选项，我在 .exe 文件中不需要控制台

这里还有speedtest.py

假设我有以下仅由 16 位值组成的列表：

[65534, 65535, 0, 1 ...... 65534, 65535, 0 , 1 , 3,  4 ]

我想将其转换为 32 位列表，例如：

[65534, 65535, 65536, 65537 ...... 131070, 131071, 131072 , 131073 , 131075,  131076 ]

这意味着遇到 0 后，值应该增加 2 ¹⁶ (65536)，并且任何大于 1 的差值（例如从 1 到 3）都应保留。

在 Python 中是否有一种有效的方法可以做到这一点？我的数组由数百万个点组成。

编辑 ：

我在 julia （https://gist.github.com/ssfrr/7995008）中发现了这一点，它似乎有效。

function unwrap(v, inplace=false)
    # currently assuming an array
    unwrapped = inplace ? v : copy(v)
    for i in 2:length(v)
      while unwrapped[i] - unwrapped[i-1] >= pi
        unwrapped[i] -= 2^4
      end
      while unwrapped[i] - unwrapped[i-1] <= -pi
        unwrapped[i] += 2^4
      end
    end
    return unwrapped
  end
  
  test_v = [15, 0, 1 , 2,  3,  6, 8, 14, 15, 0, 1] 
  res_v = unwrap(test_v)

我应该如何在 Microsoft Graph API 中更新预约中的 customQuestionAnswers？这是我尝试过的：

修补https://graph.microsoft.com/v1.0/solutions/bookingBusinesses/<businessId>/appointments/<appointmentId>

{
  "@odata.type": "#microsoft.graph.bookingAppointment",
  "customers": [
    {
      "@odata.type": "#microsoft.graph.bookingCustomerInformation",
      "customerId": "<my-customer-id>",
      "emailAddress": "[email protected]",
      "location": null,
      "name": "Test Testson",
      "notes": "",
      "phone": null,
      "timeZone": null,
      "customQuestionAnswers": [
        {
          "@odata.type": "microsoft.graph.bookingQuestionAnswer",
          "questionId": "9f66cb07-abbc-4427-b3ea-b6a4da80d10d",
          "isRequired": true,
          "selectedOptions": [
            "Video"
          ],
          "question": "Mötestyp",
          "answerOptions": [
            "Video",
            "Telefon"
          ],
          "answerInputType": "radioButton"
        }
      ]
    }
  ]
}

这会导致以下错误：

{
    "error": {
        "code": "UnknownError",
        "message": "",
        "innerError": {
            "date": "2025-02-11T12:40:27",
            "request-id": "f10492fe-93f6-42b7-8cc4-f675fa705e47",
            "client-request-id": "f713f76d-c962-a2e9-8694-7fafa2f83eb1"
        }
    }
}

删除 customQuestionAnswers 块可以“解决”该问题。

最近我遇到以下问题：我在 ListView 里面有一张卡片，我想通过设置颜色来为卡片设置主题，Theme.of(context).colorScheme.surfaceContainer但现在的问题是，当我切换主题时，颜色不会刷新。

我在这里创建了此问题的最小可重现示例

import 'package:flutter/material.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatefulWidget {
  const MainApp({super.key});

  @override
  State<MainApp> createState() => _MainAppState();
}

class _MainAppState extends State<MainApp> {
  ThemeMode _themeMode = ThemeMode.light;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(),
      darkTheme: ThemeData(brightness: Brightness.dark),
      themeMode: _themeMode,
      home: Scaffold(
        body: Padding(
          padding: const EdgeInsets.all(8.0),
          child: Center(
              child: Column(
            spacing: 8,
            mainAxisSize: MainAxisSize.min,
            children: [
              ElevatedButton(
                  onPressed: () {
                    setState(() {
                      _themeMode = _themeMode == ThemeMode.light
                          ? ThemeMode.dark
                          : ThemeMode.light;
                    });
                  },
                  child: Text("Change Theme")),
              Expanded(child: MyList())
            ],
          )),
        ),
      ),
    );
  }
}

class MyList extends StatelessWidget {
  const MyList({super.key});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
        itemCount: 10,
        itemBuilder: (context, index) {
          return Card(
            color: Theme.of(context).colorScheme.surfaceContainer,
            child: ListTile(
              title: Text('Item $index'),
            ),
          );
        });
  }
}

当我打开应用程序时，一切看起来都符合预期：

现在我点击“更改主题”按钮，然后发生以下情况：

不确定这是我遗漏了什么还是 Flutter 框架的问题（不太可能）。

我尝试删除ListView，并且仅Card在小部件内部放一个 即可解决问题，但当然，对于我的真实应用程序，我需要将卡片放在 中ListView。

还要注意，滚动时，如果卡片超出屏幕范围，然后将其滚动回屏幕，它会重新获取颜色并正确显示。

我想在 Flutter GitHub repo 上提出问题之前先在这里问一下。

我需要实现允许用户通过文本字段将图像从剪贴板粘贴到我的 Android Kotlin Compose 应用程序中的功能，我需要一些帮助。

我看到有人使用 BasicTextField2 和 Modifier.receiveContent()，就像那篇博客中说的一样：https ://blog.shreyaspatil.dev/rich-media-input-from-the-keyboard-in-compose 。但它不起作用，因为 BasicTextField2 实际上已从 Compose 中删除。也许有一些解决方案在 2025 年 2 月起有效？
