我有完整的HTML代码与以下JS脚本,当我打开它通过我的域,我得到这个消息:

已被CORS策略阻止:请求的资源上不存在“Access-Control-Allow-Origin”标头

我希望它的工作,为其他用户不仅为我,为任何人都有链接。

const baseUrl = "my api url"
    

    function getMatches()
    {
        const url = `${baseUrl}`

        axios.get(url)
               .then((data) => {
            console.log(data)

            const matches = data.data.data.match
            console.log(matches)
            
           
            document.getElementById("matches").innerHTML = ""

            for(match of matches)
            {
                
              
                if(match.home_name == null)
                {
                    
                    continue
                }
                console.log(match.home_name)
                const content = `
                <div class="col-sm-12">

                `
                
                document.getElementById("matches").innerHTML += content
            }
        
        })
    }
    getMatches()

我在本地服务器上面对它,但我跳过了使用没有CORS的谷歌Chrome。

mrwjdhj31#

async function postData(url = '', data = {}) {
  const response = await fetch(url, {
    method: 'POST',
    mode: 'no-cors', //cors, same-origin
    headers: {
      'Content-Type': 'application/json'
      // 'Content-Type': 'application/x-www-form-urlencoded',
    },
    body: JSON.stringify(data)
  });
  return response.json(); // parses JSON response into native JavaScript objects
}

postData('URL', { answer: 42 })
  .then((data) => {
    console.log(data); // JSON data parsed by `data.json()` call
  });

CORS是安全性的重要组成部分,由服务器(后端)处理。如果设置了此选项,则允许配置的IP地址访问该Web应用程序。
