编辑:我已经添加了来自OMDB的响应
{Response: "False", Error: "Invalid API key!"}
Error: "Invalid API key!"
Response: "False"
我是Web开发的新手,我正在尝试构建一个chrome扩展程序,以在netflix上显示imdb分数。我正在使用OMDB API来执行此操作。一开始我遇到以下错误:
“混合内容:位于处的页面已通过HTTPS加载,但请求了不安全的XMLHttpRequest端点。该请求已被阻止;必须通过HTTPS提供内容。”
但是我只是将URL中的“ http”更改为“ https”,但它消失了。但是,现在我收到401错误,我认为这意味着我的访问被拒绝。这是完整错误的图片
这是扩展的代码

对OMDB发布请求和响应将很有帮助(您可以在开发工具的“网络”选项卡中找到它们)。
有一两件事触发CORS(跨域请求)错误时,指定以外的内容类型application/x-www-form-urlencoded
,multipart/form-data
或text/plain
。如果我没记错的话,即使不指定请求的内容类型,OMDB API也会返回JSON响应,因此您应该尝试删除以下行:
xhr.setRequestHeader('Content-Type', 'application/json');
有关不会触发CORS的“简单请求”的更多信息:https : //javascript.info/fetch-crossorigin#simple-requests
您还需要获取一个API密钥(https://www.omdbapi.com/apikey.aspx),并**{API_KEY}**
用该密钥替换代码。您还需要将t
关键字添加到查询字符串中,否则标题将附加到您的API关键字中。
var url = "https://www.omdbapi.com/?i=tt3896198&apikey=**{API_KEY}**" + "&t="
+ encodeURI(name) + "&y=" + year + "tomatoes=true";
