尝试从本地主机访问api时如何解决"Access-Control-Allow-Origin"错误 [英] How to solve 'Access-Control-Allow-Origin' error when trying to access api from localhost

问题描述

我已经看到很多有关此错误的主题，但是我对js和api还是很陌生，所以我不太了解，所以我为菜鸟身份道歉.

I've seen a lot of topics on this error, but I'm very new to js and apis, so I couldn't really understand much, so I apologize for noob status.

我正在尝试从sportradar访问api.我正在从create-react-app使用axios创建的一个简单的react项目上对其进行测试.当我console.log数据时，出现以下错误: https://dzwonsemrish7.cloudfront.net/items/372w3g2b3F141t2P0K1G/Image%202018-09-04%20at%2011.33.38%20AM.png

I'm trying to access an api from sportradar. I'm testing it out on a simple react project created from create-react-app and using axios. When I console.log the data I get these errors: https://dzwonsemrish7.cloudfront.net/items/372w3g2b3F141t2P0K1G/Image%202018-09-04%20at%2011.33.38%20AM.png

我猜我无法从本地主机访问它?这是我的请求功能:

I guess I can't access it from a local host? here is my function with the request:

getPlayerInfo() {
  const apiKey = "my-api-key";
  const playerID = "41c44740-d0f6-44ab-8347-3b5d515e5ecf";
  const url = `http://api.sportradar.us/nfl/official/trial/v5/en/players/${playerID}/profile.json?api_key=${apiKey}`;


  axios.get(url).then(response => console.log(response));
}

推荐答案

如果后端支持CORS，则可能需要在请求中添加以下标头:

If the backend support CORS, you probably need to add to your request this header:

headers: {"Access-Control-Allow-Origin": "*"}

您的代码如下:

getPlayerInfo() {
  const apiKey = "my-api-key";
  const playerID = "41c44740-d0f6-44ab-8347-3b5d515e5ecf";
  const url = `http://api.sportradar.us/nfl/official/trial/v5/en/players/${playerID}/profile.json?api_key=${apiKey}`;
  const config = {
    headers: {'Access-Control-Allow-Origin': '*'}
  };


  axios.get(url,config).then(response => console.log(response));
}
