当我添加回调手机函数时,等待等待。如果您不包含回调函数,它可以正常工作。即,这样做

fileHash=await ipfs.files.add(testBuffer);

The await did not work as I was adding a callback frunction also. It works fine if you don't include the callback function. ie, do it like

fileHash=await ipfs.files.add(testBuffer);

ipfs.files.add不在等待

我不知道您是否弄清楚了这一点,但是今天我遇到了同样的问题,这就是我用脉轮 - UI解决的。创建一个单独的函数并像这样写逻辑...

import { useToast } from "@chakra-ui/react";

export const CustomToast = () => {
    const toast = useToast();
    // types are: "success", "info", "warning", "error"

    const addToast = (newRes) => {
        toast({
            description:newRes.message, 
            status: newRes.type, 
            position:"top-right", 
            isClosable: true, 
            duration: 5000,
            variant: 'left-accent' 
        })
    }
    
    return { addToast };
}

然后从“ ../ path/to/file”中导入addtoast方法import {addToast} = CustomToast();并通过将破坏的对象传递到addtoast函数addToast({消息:“ insucy”,type:“ success”}) ... i来使用它。希望这对这里的其他人有帮助。

I don't know if you ever figured this out, but I ran into the same problem today, and here's how I resolved it with Chakra-UI. Create a separate function and write the logic like this...

import { useToast } from "@chakra-ui/react";

export const CustomToast = () => {
    const toast = useToast();
    // types are: "success", "info", "warning", "error"

    const addToast = (newRes) => {
        toast({
            description:newRes.message, 
            status: newRes.type, 
            position:"top-right", 
            isClosable: true, 
            duration: 5000,
            variant: 'left-accent' 
        })
    }
    
    return { addToast };
}

Then import the addToast method anywhere in your application import { addToast } from "../path/to/file";, create an instance const { addToast } = CustomToast(); and use it by passing a destructured object to the addToast function addToast({message: "sign in successful", type: "success"})... I hope this helps someone else out here.

如何创建可重复使用的脉轮UI吐司

您还可以尝试下面的尝试,它使用文本进行contet html,然后使用dangernlysetinnerhtml进行html。

import React from 'react';
import './App.css';

function App() {
  let someHtml = ``;
  let x = 5;
  let y = 10;
  for (let i = 0; i <= x; i++) {
    someHtml += `<div className='someCSS'>`
    for (let j = 0; j <= y; j++) {
      someHtml += `<div className='someOtherCSS'></div>`;
    }
    someHtml += '</div>'
  }


  return (
    <div className="App" dangerouslySetInnerHTML={{__html: someHtml}} />
  );
}

export default App;

You can give a below try also, it uses text for concat the html and then dangerouslySetInnerHTML to string HTML.

import React from 'react';
import './App.css';

function App() {
  let someHtml = ``;
  let x = 5;
  let y = 10;
  for (let i = 0; i <= x; i++) {
    someHtml += `<div className='someCSS'>`
    for (let j = 0; j <= y; j++) {
      someHtml += `<div className='someOtherCSS'></div>`;
    }
    someHtml += '</div>'
  }


  return (
    <div className="App" dangerouslySetInnerHTML={{__html: someHtml}} />
  );
}

export default App;

待定意味着要待交付给订阅的Webhook URL。该事件已尝试,并尝试将其传递到URL,但是该URL并未以HTTP 200成功的消息响应,以确保Webhook已成功交付。实际上,根据您的问题记录的详细信息:

        "webhook_url": "https://www.myapp.com/webhook",
        "http_status": 440,

假设URL正确,并且您将其更改为“ myApp”,则用HTTP 440状态响应了

URL,因此您需要调试端点/端点/该网址处的代码,以便在将Webhook交付发布到它时具有200个成功状态。那么他们的身份将不再悬而未决。

Pending means pending delivery to the subscribed webhook URL. The event ocurred, and delivery to the URL was attempted, but that URL did not respond with an HTTP 200 success message for the webhook to be marked as successfully delivered. In fact, according to the details logged in your question:

        "webhook_url": "https://www.myapp.com/webhook",
        "http_status": 440,

That URL instead responded with an HTTP 440 status

Assuming the URL is correct and that you changed it to "myapp" for this question, the issue is that you need to debug the endpoint/code at that URL so that it responds with a 200 success status when webhook deliveries are posted to it. Then their status will stop being Pending.

就像@saeed Noshadi所说,您可以用实际查询替换URL的已知部分,但是当您获得多个查询时,它可能会变得凌乱。
因此,我建议用您的base_url构建URL,然后根据需要在每个API调用中添加残留部分
喜欢 -

class ApiServiceImpl(val client: HttpClient) {
    suspend fun doHttpCall(baseUrl: String, queries:List<String>,) {
        client.get {
            url(baseUrl + queries.map { "/$it/" } + "sug/on")
        }
     }
}

like @Saeed Noshadi said, you can replace a known part of your URL with the actual query but it might get messy when you get more than one query to add.
hence I suggest to build the url with your BASE_URL and then add the remains part as needed in each API call
like so -

class ApiServiceImpl(val client: HttpClient) {
    suspend fun doHttpCall(baseUrl: String, queries:List<String>,) {
        client.get {
            url(baseUrl + queries.map { "/$it/" } + "sug/on")
        }
     }
}

如果您需要使用需要使用import的自定义类型扩展window对象,则可以使用以下方法:

window.d.t.ts

import MyInterface from './MyInterface';

declare global {
    interface Window {
        propName: MyInterface
    }

If you need to extend the window object with a custom type that requires the use of import, you can use the following method:

window.d.ts

import MyInterface from './MyInterface';

declare global {
    interface Window {
        propName: MyInterface
    }
}

See Global Augmentation in the 'Declaration Merging' section of the Handbook.

这可能是PowerShell的代码线太多,但对我有用:

Clear-Host
$currentProperty = (Get-ItemProperty -Path Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Bentley\BentleyDesktopClient\Install | Select-Object -ExpandProperty "UpdateClient")
#You may need this to compare in the future
$newProperty = $currentProperty

#Searching value KeyName_CheckUpdateOption. If value set - replace it, if not - set it
$CurrentKeyName_CheckUpdateOption = $null
$CurrentKeyName_CheckUpdateOption = ($newProperty | Select-String -Pattern 'KeyName_CheckUpdateOption=([0-9.]+)')
if($CurrentKeyName_CheckUpdateOption.Matches.Value) {
    Write-Output $CurrentKeyName_CheckUpdateOption.Matches.Value
    $newProperty = $newProperty.Replace("$($CurrentKeyName_CheckUpdateOption.Matches.Value)","KeyName_CheckUpdateOption=3")
} else {
    $newProperty = $newProperty.Replace("KeyName_CheckUpdateOption=","KeyName_CheckUpdateOption=3")
}

#Same for KeyName_CheckUpdateIsEnabled.
$CurrentKeyName_CheckUpdateIsEnabled = $null
$CurrentKeyName_CheckUpdateIsEnabled = ($newProperty | Select-String -Pattern 'KeyName_CheckUpdateIsEnabled=([0-9.]+)')
if($CurrentKeyName_CheckUpdateIsEnabled.Matches.Value) {
    $newProperty = $newProperty.Replace("$($CurrentKeyName_CheckUpdateIsEnabled.Matches.Value)","KeyName_CheckUpdateIsEnabled=0")
} else {
    $newProperty = $newProperty.Replace("KeyName_CheckUpdateIsEnabled=","KeyName_CheckUpdateIsEnabled=0")
}

# Set updated value to registry
Set-ItemProperty -Path HKLM:\SOFTWARE\Bentley\BentleyDesktopClient\Install -Name UpdateClient -Value $newProperty

This may be too much code lines of powershell, but it works for me:

Clear-Host
$currentProperty = (Get-ItemProperty -Path Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Bentley\BentleyDesktopClient\Install | Select-Object -ExpandProperty "UpdateClient")
#You may need this to compare in the future
$newProperty = $currentProperty

#Searching value KeyName_CheckUpdateOption. If value set - replace it, if not - set it
$CurrentKeyName_CheckUpdateOption = $null
$CurrentKeyName_CheckUpdateOption = ($newProperty | Select-String -Pattern 'KeyName_CheckUpdateOption=([0-9.]+)')
if($CurrentKeyName_CheckUpdateOption.Matches.Value) {
    Write-Output $CurrentKeyName_CheckUpdateOption.Matches.Value
    $newProperty = $newProperty.Replace("$($CurrentKeyName_CheckUpdateOption.Matches.Value)","KeyName_CheckUpdateOption=3")
} else {
    $newProperty = $newProperty.Replace("KeyName_CheckUpdateOption=","KeyName_CheckUpdateOption=3")
}

#Same for KeyName_CheckUpdateIsEnabled.
$CurrentKeyName_CheckUpdateIsEnabled = $null
$CurrentKeyName_CheckUpdateIsEnabled = ($newProperty | Select-String -Pattern 'KeyName_CheckUpdateIsEnabled=([0-9.]+)')
if($CurrentKeyName_CheckUpdateIsEnabled.Matches.Value) {
    $newProperty = $newProperty.Replace("$($CurrentKeyName_CheckUpdateIsEnabled.Matches.Value)","KeyName_CheckUpdateIsEnabled=0")
} else {
    $newProperty = $newProperty.Replace("KeyName_CheckUpdateIsEnabled=","KeyName_CheckUpdateIsEnabled=0")
}

# Set updated value to registry
Set-ItemProperty -Path HKLM:\SOFTWARE\Bentley\BentleyDesktopClient\Install -Name UpdateClient -Value $newProperty

以下代码将与ul&gt; li标签

soup = BeautifulSoup(driver.page_source, 'html.parser')

for li in soup.find_all('ul',class_="nb-type-md nb-list-undecorated undefined"):
    name = li.select_one('[class="nb-type-md nb-list-undecorated undefined"] li:nth-child(1) > span').get_text()
    location = li.select_one('[class="nb-type-md nb-list-undecorated undefined"] li:nth-child(2) > span').get_text()
    year = li.select_one('[class="nb-type-md nb-list-undecorated undefined"] li:nth-child(3) > span').get_text()
    link = li.select_one('[class="nb-type-md nb-list-undecorated undefined"] li:nth-child(4) > span').get_text()

    print(name)
    print(location)
    print(year)
    print(link)

输出:

AMCS

Founded in 2004
http://www.amcsgroup.com/

更新:

li=[x.get_text() for x in soup.select('[class="nb-type-md nb-list-undecorated undefined"] li span')]
print(li) 

输出:

['AMCS', 'Located in United States', 'Founded in 2004', 'http://www.amcsgroup.com/']

The following code will pull all the text nodes value separately from ul > li tags

理解GPU风格的SIMD执行模型的关键是,Wavefront/simd组中的所有线程始终同时执行完全相同的指令。如果线程不需要运行指令至少一个其他线程必须执行,不会有任何副作用(寄存器值不会更改等),但是在性能方面,它仍然像确实运行它一样成本。

如果分支条件为 所有螺纹的分支条件是Wavefront/simd组中的所有线程,则所有线程仅运行一个分支,然后跳过另一个分支。因此,如果工作负载中几乎所有线程的条件相同,或者您可以安排一个组中的所有线程的条件相同,则您不支付分歧成本。 (或它变得可忽略。)

如果 在组内频繁的差异,则整个波前需要执行两个分支。发生这种情况时,不需要实际运行代码的线程仍将逐步浏览其他线程所要求的指令,与其他线程完全相同,它只是没有效果。与硬件CPU线程不同,GPU线程不能与其他线程(在同一SIMD组中)运行不同的代码,它只能在不同的数据上运行相同的代码,或者必须等到其他线程完成代码完成代码不需要运行。

The key to understanding the GPU-style SIMD execution model is that all threads in a wavefront/SIMD group always execute the exact same instruction at the same time. If a thread doesn't need to run an instruction that at least one other thread must execute, there won't be any side effects (register values won't change, etc.), but it still costs as much in terms of performance as if it really did run it.

If the branching condition is either true or false for all threads in a wavefront/SIMD group, then all threads only run the one branch, and the other branch is skipped. So if the condition is the same for almost all threads in your workload, or if you can arrange for the condition to be the same for all threads in a group, then you don't pay the divergence cost. (Or it becomes negligible.)

If there is a frequent divergence within the group, the whole wavefront needs to execute both branches. When this happens, the threads which don't need to actually run the code, will still step through those instructions required by the other threads at exactly the same time as those other threads, it just has no effect. Unlike hardware CPU threads, a GPU thread can't run different code from other threads (in the same SIMD group), it can only run the same code on different data, or it has to wait until the other threads have finished the code it doesn't need to run.

混合仅在深度测试是禁用的,或者对象是从后至前面绘制的。当启用深度测试(具有默认函数gl_less)时,更远的对象会赢得更遥远的对象。即使碎片的α通道为0,片段也会影响深度缓冲区和深度测试。因此,如果先前绘制了更近的透明片段,则会丢弃更遥远的片段。
您只有一个具有透明片段的对象,即网格。要解决您的问题,只需在立方体之后绘制网格:

  • 启用深度测试
  • 绘制固体对象(cube)
  • 启用混合
  • 绘制网格

Blending only works when the Depth Test is disabled or the objects are drawn from back to front. When the depth test is enabled (with its default function GL_LESS) closer objects win against more distant objects. Even if a fragment's alpha channel is 0, the fragment affects the depth buffer and the depth test. Thus, a more distant fragment is discarded if a closer, transparent fragment was previously drawn.
You only have one object with transparent fragments, the grid. To solve your problem, just draw the grid after the cube:

  • enable depth test
  • draw solid objects (cube)
  • enable blending
  • draw grid

简短的答案是否定的,但这并不意味着您不能使用它来根据某些.onchange(..)操作更改视图。例如。

@State var somethingChanged = false 
Text(somethingChanged ? "First Value" : "Second Value")

// Your code/view
    .onChange(..) {
         //Some Condition or whatever you want.
         somethingChanged = true
    }

您的用法可能看起来像这样。

content
    .foregroundColor(somethingChanged ? .red : .blue)
    .onChange(ofPublishedValue) {
        somethingChanged = true
    }

The short answer is no, but that doesn't mean you can't use it to have views change based on some .onChange(..) action. For example.

@State var somethingChanged = false 
Text(somethingChanged ? "First Value" : "Second Value")

// Your code/view
    .onChange(..) {
         //Some Condition or whatever you want.
         somethingChanged = true
    }

Your usage might look something like this.

content
    .foregroundColor(somethingChanged ? .red : .blue)
    .onChange(ofPublishedValue) {
        somethingChanged = true
    }
