如果Service2Method返回可观察到的可观察,则需要订阅以实际致电。在当前实施中,您从未订阅过它,因此此方法从未被调用。

您可以在现有的订阅中添加另一个订阅(这是一种不良方法,但会起作用),也可以使用扁平的操作员(SwitchMap,Mergemap或任何其他)将单个订阅纳入您的功能中。

If the service2Method returns an observable, you need to subscribe to actually call if. In the current implementatation you never subscribed to it, so this method is never called.

You can either add another subscribe inside the existing one (which is a bad approach, but will work) or use a flattening operator (switchmap, mergemap or any other) to have a single subscribe into your function.

尝试在另一个服务调用的订阅()中测试服务调用

由于您删除了迁移,因此问题必须是Django失去了桌子上的约束。您应该寻找一种直接从数据库中删除而不是无效约束的方法。也许尝试

Since you've deleted your migrations, the problem must be that Django has lost track of what constraints are on your tables. You should look for a way to delete that NOT NULL constraint directly from the database. Maybe try this

我设置了null = true and black = true,但仍然获取“ django.db.utils.integrityerror :( 1048,columt; massenger_name; null; smassenger_name;

使您的生活更轻松,不要更难 - 使用普通DTO

class AccessTokenResponse{
  @JsonProperty("access_token");
  String accessToken
  //other props you are interested in
  //+ getters/setters
}

然后

   AccessTokenResponse response = restTemplate.postForObject( url, request , AccessTokenResponse.class );
    
   response.getAccessToken(); //here you have it

Make your life easier, not harder - use plain DTO

class AccessTokenResponse{
  @JsonProperty("access_token");
  String accessToken
  //other props you are interested in
  //+ getters/setters
}

and then

   AccessTokenResponse response = restTemplate.postForObject( url, request , AccessTokenResponse.class );
    
   response.getAccessToken(); //here you have it

rfc7230 指定如何在HTTTPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPER中指定如何。

如果使用
双引号标记。

 引用 - 弦= dquote *(qdtext / quoted pair)dquote
 qdText = htab / sp /%x21 /%x23-5b /%x5D-7e / obs-Text
 obs-Text =%x80-ff
 

Backslash Octet(“”)可以用作单一引用
引用弦和评论构造中的机制。收件人
该过程的引号的价值必须处理引号
好像在后斜线后将其替换为八位字节。

 引用pair =“ \”(htab / sp / vchar / obs-text)
 

这解释了Backslash逃脱的工作原理,并指出它包括上十六进制范围以及ASCII角色。

RFC7230 specifies how backslash escaping works for quoted strings in HTTP headers.

A string of text is parsed as a single value if it is quoted using
double-quote marks.

 quoted-string  = DQUOTE *( qdtext / quoted-pair ) DQUOTE
 qdtext         = HTAB / SP /%x21 / %x23-5B / %x5D-7E / obs-text
 obs-text       = %x80-FF

The backslash octet ("") can be used as a single-octet quoting
mechanism within quoted-string and comment constructs. Recipients
that process the value of a quoted-string MUST handle a quoted-pair
as if it were replaced by the octet following the backslash.

 quoted-pair    = "\" ( HTAB / SP / VCHAR / obs-text )

This explains how backslash escaping works, and note that it includes the upper hex range as well as just the ASCII characters.

您可以使用螺纹并将其全部保持在相同的过程中:

from multiprocessing import Queue
from Queue import Empty
from threading import Thread

def sub_proc(q):
    some_str = ""
    while True:
        some_str = raw_input("> ")
        if some_str.lower() == "quit":
            return
        q.put_nowait(some_str)

if __name__ == "__main__":
    q = Queue()
    qproc = Thread(target=sub_proc, args=(q,))
    qproc.start()
    qproc.join()

    while True:
        try:
            print q.get(False)
        except Empty:
            break

You could use threading and keep it all on the same process:

from multiprocessing import Queue
from Queue import Empty
from threading import Thread

def sub_proc(q):
    some_str = ""
    while True:
        some_str = raw_input("> ")
        if some_str.lower() == "quit":
            return
        q.put_nowait(some_str)

if __name__ == "__main__":
    q = Queue()
    qproc = Thread(target=sub_proc, args=(q,))
    qproc.start()
    qproc.join()

    while True:
        try:
            print q.get(False)
        except Empty:
            break

在AirFlow 2.4.3中,在[WebServer] airflow.cfg的部分中,从默认的false更改属性expose_config expose_config /code> <代码> true 或非敏感 - 仅,具体取决于您想向UI用户暴露的内容:

# Expose the configuration file in the web server. Set to "non-sensitive- only" to show all values
# except those that have security implications. "True" shows all values. "False" hides the
# configuration completely.
expose_config = False

In Airflow 2.4.3, in the [webserver] section of airflow.cfg, change the property expose_config from the default False to True or non-sensitive- only, depending on what you want to expose to the UI users:

# Expose the configuration file in the web server. Set to "non-sensitive- only" to show all values
# except those that have security implications. "True" shows all values. "False" hides the
# configuration completely.
expose_config = False

虽然上面的正确答案使用了示例的文件流。pdf

(BytesIO(response.content)
with fitz.open(stream=pdf) as doc:

仍然必须通过超级文本响应(下载)从https转移(下载),然后由fitz解码为%tmp%memoryblob.pdf(因此,下载的文件和下载的文件提取后被丢弃),

如果您只想使用OS和Poppler进行类似的操作,以便能够尝试不同的选项。序列只是为

curl -o "%tmp%\temp.pdf" RemoteURL
pdftotext [options] "%tmp%\temp.pdf" filename.txt

您提供无限的时间来重播最后一行,下次覆盖相同的%TMP%内存文件。如果将选项设置并将filename.txt更改为-您可以查看控制台输出,但是要当心非本机编码,控制台可能会出现Cruder Output,而不是在文件名。

Whilst the correct given answer above uses a FileStream for sample.pdf

(BytesIO(response.content)
with fitz.open(stream=pdf) as doc:

It still had to be transferred down from https via hyper text response (download) and then decoded by fitz as a %tmp%MemoryBlob.pdf (thus a file that was downloaded and discarded after extraction)

If you want to do similar using just the OS and Poppler to be able to tryout different options the sequence is simply

curl -o "%tmp%\temp.pdf" RemoteURL
pdftotext [options] "%tmp%\temp.pdf" filename.txt

It gives you infinite time to replay the last line and next time overwrite the same %tmp% memory file. If you set options and change filename.txt to simply - you can review the console output, however beware for non native encodings the console may appear cruder output than would be stored in a filename.

您只需在数组中配置CORS,在特定域或多个域:

   var cors = require('cors');

//在所有路由定义之前使用它

app.use(cors({origin: 'http://localhost:3000',credentials: true}));  

app.use(cors({origin: ['http://localhost:8001','http://localhost:8000'],credentials: true})); 

You just configure cors, To a specific domain or multiple domains in an array:

   var cors = require('cors');

// use it before all route definitions

app.use(cors({origin: 'http://localhost:3000',credentials: true}));  

app.use(cors({origin: ['http://localhost:8001','http://localhost:8000'],credentials: true})); 

获得不存在的&#x27; allow-access-allow-origin&#x27; NODEJS应用程序中的标题问题

您需要另外拦截 did-reate-window 创建窗口时会触发的事件:

mainWindow.webContents.on("did-create-window", (window, details) => {
    window.webContents.once("dom-ready", () => window.webContents.openDevTools());
});

You'd need to additionally intercept the did-create-window event which fires when the window is created:

mainWindow.webContents.on("did-create-window", (window, details) => {
    window.webContents.once("dom-ready", () => window.webContents.openDevTools());
});

使用setWindowopenhandler时,电子显示新窗口上的DevTools

final_error_code在循环中定义。

如果未定义,则意味着您的循环根本没有循环。

您的循环条件为:re.finditer('pt-',error_str),所以我假设re.finditer(...)什么都没找到。

final_error_code is defined in your loop.

If it is not defined, that means that your loop didn't loop at all.

Your for loop condition is: re.finditer('PT-', error_str), so I assume that re.finditer(...) didn't find anything.

名称:name&#x27; final_error_code&#x27;未定义

您可以使用更新映射。

  1. 创建新字段

put demo-index/_mapping

 {
      "properties": {
        "hello_metadata": {
          "type": "nested",
          "properties": {
            "cheese": {
              "type": "text"
            }
          }
        }
      }
    }
  1. 更新您的文档,如果要定位特定的字段(例如,例如_metadata),请使用查询。

You can use update mapping.

  1. Create the new field

PUT demo-index/_mapping

 {
      "properties": {
        "hello_metadata": {
          "type": "nested",
          "properties": {
            "cheese": {
              "type": "text"
            }
          }
        }
      }
    }
  1. Update your document, using query if you want to target specific ones (containing _metadata for example).

将新字段添加到Elasticsearch中的许多嵌套对象

所需元素的id属性看起来动态性,并且该元素本身可能是动态元素,因此要单击 clickable 元素,您需要诱导 webdriverwait 对于 element_to_be_clickable() 您可以使用以下任何一个 Locator Strategies

  • 使用 partial_link_text

     tillfällig导出
     
  • 使用 css_selector

      a.utdatanodlink [id*='linkb']
     
  • 使用 xpath

      // a [@class ='utdatanodlink'并包含(。,'tillfällig导出')]
     

The id attribute of the desired element looks dynamic and the element itself is possibly a dynamic element so to click on the clickable element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:

  • Using PARTIAL_LINK_TEXT:

    Tillfällig export
    
  • Using CSS_SELECTOR:

    a.UTDATANODLINK[id*='linkb']
    
  • Using XPATH:

    //a[@class='UTDATANODLINK' and contains(., 'Tillfällig export')]

是的,有可能造成多个 nft 在单个tokenmintTransaction()中,有一些内容要注意。

交易具有最大大小为6,144 kb,包括签名。

.setMetadata()接受NFT元数据的数组。每个数组元素将导致NFT,并在令牌类型下创建唯一的序列号。交易的收据将包括交易创建的所有新序列号。

重要的是要密切关注您的元数据大小,因为如果您在数组中放置了太多的项目,您将收到transaction_oversize错误,并且不会造成NFT。

这是单个交易中造成多个NFT的示例:

let metadata = [];
let CID = [];
for (let i = 0; i < 3; i++) {
  // NFT STORAGE
  const fileName = `LEAF${i + 1}.jpg`;
  metadata[i] = await nftClient.store({
    name: `LEAF${i + 1}`,
    description: "Leaf NFT.",
    image: new File([await fs.promises.readFile(fileName)], fileName, { type: "image/jpg" }),
  });

  CID[i] = Buffer.from(metadata[i].url);

  // IPFS URI FOR NFT METADATA - See HIP-412: https://hips.hedera.com/hip/hip-412
  let ipfsBaseUrl = "https://ipfs.io/ipfs/";
  let ipfsGatewayLink = ipfsBaseUrl + metadata[i].ipnft + "/metadata.json";
  console.log(`- IPFS link for serial ${i + 1}: ${ipfsGatewayLink} \n`);
}

// MINT NEW BATCH OF NFTs
let mintTx = new TokenMintTransaction().setTokenId(tokenId).setMetadata(CID).freezeWith(client);
let mintTxSign = await mintTx.sign(operatorKey);
let mintTxSubmit = await mintTxSign.execute(client);
let mintRec = await mintTxSubmit.getRecord(client);

console.log(`- Minting fees: ${mintRec.transactionFee._valueInTinybar.c[0] * 1e-8} hbar \n`);

虽然可能无法一次创建100个NFT,但您应该一次进行数十个(取决于元数据大小)。

Yes, it is possible to mint multiple NFT's in a single TokenMintTransaction() but there are things to note.

A transaction has a max size of 6,144 kb including signatures.

.setMetadata() accepts an array of NFT metadata. Each array element will result in an NFT with a unique serial number being created under the token type. The receipt for the transaction will include all the new serial numbers that were created by the transaction.

It is important to keep an eye on your metadata size because if you put too many items in the array, you will receive a TRANSACTION_OVERSIZE error and no NFT's will be minted.

Here is an example for minting multiple NFT's in a single transaction:

let metadata = [];
let CID = [];
for (let i = 0; i < 3; i++) {
  // NFT STORAGE
  const fileName = `LEAF${i + 1}.jpg`;
  metadata[i] = await nftClient.store({
    name: `LEAF${i + 1}`,
    description: "Leaf NFT.",
    image: new File([await fs.promises.readFile(fileName)], fileName, { type: "image/jpg" }),
  });

  CID[i] = Buffer.from(metadata[i].url);

  // IPFS URI FOR NFT METADATA - See HIP-412: https://hips.hedera.com/hip/hip-412
  let ipfsBaseUrl = "https://ipfs.io/ipfs/";
  let ipfsGatewayLink = ipfsBaseUrl + metadata[i].ipnft + "/metadata.json";
  console.log(`- IPFS link for serial ${i + 1}: ${ipfsGatewayLink} \n`);
}

// MINT NEW BATCH OF NFTs
let mintTx = new TokenMintTransaction().setTokenId(tokenId).setMetadata(CID).freezeWith(client);
let mintTxSign = await mintTx.sign(operatorKey);
let mintTxSubmit = await mintTxSign.execute(client);
let mintRec = await mintTxSubmit.getRecord(client);

console.log(`- Minting fees: ${mintRec.transactionFee._valueInTinybar.c[0] * 1e-8} hbar \n`);

While creating 100 NFT's at a time may not be possible, you should be able to do tens at a time (depending on the metadata size).

如何在HEDERA上造成多个NFT,仅称TokenMintTransaction一次?

如果您需要$ search出现在请求的URL中,则需要逃脱美元符号,否则PowerShell将被视为变量。

$api = "https://graph.microsoft.com/V1.0/$upn/messages?`$search='subject:INC0432318'"

If you need $search to show up in the URL of the request you need to escape the dollar sign, otherwise it will be treated as a variable by PowerShell.

$api = "https://graph.microsoft.com/V1.0/$upn/messages?`$search='subject:INC0432318'"
