我是一个新手，请帮助我创建一个 wordpress 图片短代码，就像这样简单：

[img src=""]

它显示了它的缩略图（缩略图宽度=100%），链接到 OR 时打开相同的源图像，单击时。

我尝试搜索但在现有插件中找不到，如果有请指导我。

请彻底指导我在 function.php 或其他任何地方复制粘贴。

安装 virtualenv 和 virtualenvwrapper 时出现问题，尝试时出现以下错误。任何人都可以帮助解决这些问题吗？

我试图通过Hand实现HMACSHA1,以检查我们的serviceprovider或我们为Support-Ticket计算错误的HMAC(SOAP调用,因此是xml内容).

问题是,我坚持使用NIST规范进行HMAC,并在使用openssl HMAC功能时获得不同的结果.

以下代码打印:

B92674DCBA96F2DA93F7043071B931F5F2583FBD
4303E965D88D288C9AC594CE6C5E6AFF27D40B2D

虽然openssl的结果与我们的应用程序相同 - 所以我假设,基于openssl是如此常用,我的结果是错误的 - 但我的错误在哪里？

这是我参考的规范:http: //nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.198-1.pdf

这是我的代码:

#include <stdio.h>
#include <stdlib.h>
#include <openssl/sha.h>
#include <openssl/hmac.h>
#include <string.h>

#define byte unsigned char
#define IPAD 0x36
#define OPAD 0x5c
#define DIGESTSIZE 20



int main () {
    byte *derivedKey =  (byte[DIGESTSIZE]) {0x42,0xA9,0x78,0x90,0xFC,0xE5,0x16,0x8E,0x58,0x12,0x2F,0xF1,0xBA,0x32,0x5F,0x09,0x88,0x94,0x02,0x91};
    byte *content =     "<ds:SignedInfo xmlns:ds=\"http://www.w3.org/2000/09/xmldsig#\" xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\"><ds:CanonicalizationMethod Algorithm=\"http://www.w3.org/2001/10/xml-exc-c14n#\"><ec:InclusiveNamespaces xmlns:ec=\"http://www.w3.org/2001/10/xml-exc-c14n#\" PrefixList=\"soap\"></ec:InclusiveNamespaces></ds:CanonicalizationMethod><ds:SignatureMethod Algorithm=\"http://www.w3.org/2000/09/xmldsig#hmac-sha1\"></ds:SignatureMethod><ds:Reference URI=\"#TS-B183A13FEB0189143115136776276601\"><ds:Transforms><ds:Transform Algorithm=\"http://www.w3.org/2001/10/xml-exc-c14n#\"><ec:InclusiveNamespaces xmlns:ec=\"http://www.w3.org/2001/10/xml-exc-c14n#\" PrefixList=\"wsse soap\"></ec:InclusiveNamespaces></ds:Transform></ds:Transforms><ds:DigestMethod Algorithm=\"http://www.w3.org/2000/09/xmldsig#sha1\"></ds:DigestMethod><ds:DigestValue>rXJdGuDqoRrUJxuGiA1eyAozifk=</ds:DigestValue></ds:Reference></ds:SignedInfo>";
    byte *oPadKey =     malloc(DIGESTSIZE);
    byte *iPadKey =     malloc(DIGESTSIZE);


    int i;
    for(i=0;i<DIGESTSIZE;i++){
        iPadKey[i]=derivedKey[i]^IPAD;
        oPadKey[i]=derivedKey[i]^OPAD;
    }

我怎样才能做到这一点？我的意思是显示字符的限制以及在输入文本上数字化了多少。

对不起,如果这是一个模糊的问题,但我查了很多,并且真的坚持我的代码.

我想创建一个循环,在一行打印字符串,然后在下一行打印,我的代码是:

public class StudentResult {
    public static void main(String[] args) {
        // Creating Student Objects
        Student student1 = new Student("Bob", 45);
        Student student2 = new Student("John", 70);

        // Making Arrays for students and marks
        String[] names = {student1.getStudentName(), student2.getStudentName()};
        int[] marks = { student1.getStudentMarks(), student2.getStudentMarks() };

        // Using for loop to print both names and marks

        for (int mark : marks) {
            // THIS IS THE PART I AM STUCK WITH
            if (mark == student1.getStudentMarks()) System.out.println(names[0]);
            else if (mark …

我在创建一种简单的方法来动态地将 ascii 艺术添加到实际的 javascript 确认弹出窗口中时遇到问题。我相信你们很多人都喜欢.. 为什么>!>@! 对此..我说..因为;)

现在我也许可以制作一两行作品，但每次我写一些 ASCII 艺术时，它都非常独特......所以......有人能想到一个可以让它变得更容易的函数吗？

这是我得到的最接近的一个例子。（根本不是很远）

我已经看过这个问题：FragmentContainerView using findNavController关于这个问题。但我仍然无法解决问题。它永远不会打开其他片段。我想也许是因为视图绑定，但我尝试在不使用视图绑定的情况下再次执行此操作。还没开啊

MainActivity.kt

class MainActivity : AppCompatActivity() {
    private lateinit var binding: ActivityMainBinding

    private lateinit var navController: NavController
    private lateinit var navHostFragment: NavHostFragment

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)

        val navHostFragment =
            supportFragmentManager.findFragmentById(R.id.main_nav_host_fragment) as NavHostFragment
        navController = navHostFragment.navController
        binding.bottomNavigationView.setupWithNavController(navController)
        
    }

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
        when (item.itemId) {
            R.id.home -> {
                navHostFragment.navController.popBackStack()
                return true
            }
        }
        return super.onOptionsItemSelected(item)
    }
}

我在尝试运行 React Native 项目时遇到错误。

react-native run-android

错误看起来像

请帮我。

我不熟悉 JavaScript 和 html。但我尝试使用 JavaScript 实现一个函数。

我想替换html 页面中的所有<em>and 。</em>所以我在页面中插入一段javascript代码：

function rep() \n{\n    document.body.innerHTML\n        = document.body.innerHTML\n        .replaceAll("<em>", "_");\n    document.body.innerHTML\n        = document.body.innerHTML\n        .replaceAll("</em>", "_");\n\n}\nwindow.onload=rep()

<!DOCTYPE html>\n<html lang="en">\n<!-- ... -->\n<article>\n    <div class="container">\n        <div class="row">\n            <div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1 post-container">\n\n                <p>(Weierstrass) \xe8\xae\xbe $z_{0}$ \xe6\x98\xaf $f$ \xe7\x9a\x84\xe6\x9c\xac\xe6\x80\xa7\xe5\xa5\x87\xe7\x82\xb9,\xe9\x82\xa3\xe4\xb9\x88\xe5\xaf\xb9\xe4\xbb\xbb\xe6\x84\x8f $A \\in \\mathbb{C}<em>{\\infty}$, \xe5\xbf\x85\xe5\xad\x98\xe5\x9c\xa8\xe8\xb6\x8b\xe4\xba\x8e $z</em>{0}$ \xe7\x9a\x84\xe7\x82\xb9\xe5\x88\x97 $\\left{z_{n}\\right}$, \xe4\xbd\xbf\xe5\xbe\x97 $\\lim <em>{n \\rightarrow \\infty} f\\left(z</em>{n}\\right)=A$.</p>\n\n            </div>\n        </div>\n    </div>\n<!-- ... -->\n\n</html>

\n

成功替换<em>成了“_”，但是一切都</em>没有改变。代码有什么问题吗？\n谢谢！
