Emotion API Javascript API CORS标题'Access-Control-Allow-Origin'丢失 [英] Emotion API Javascript API CORS header 'Access-Control-Allow-Origin' missing
问题描述
我想在网络应用中使用情绪检测。我错过了什么吗？ （我意识到以这种方式包含密钥是不明智的，这仅用于测试目的。）
I would like to use emotion detection in a web app. Am I missing something? (I realise it is unwise to include the key in this way, this is just for test purposes.)
我的代码是（直接来自https://dev.projectoxford.ai/docs / services /...):
My code is (straight from https://dev.projectoxford.ai/docs/services/...):
    $ .ajax（{
contentType：" application / json"，
       URL：" HTTPS：//api.projectoxford.ai/emotion/v1.0/recognize" ;,
   &NBSP ; beforeSend：function（xhrObj）{
//请求标题
         xhrObj.setRequestHeader（QUOT;内容类型"，"应用/ JSON"）;
  &NBSP ; xhrObj.setRequestHeader（" Ocp-Apim-Subscription-Key"，" ********************** **"）;
}，
type： " POST"，
data：" {'url'：'http：// *********** *********'}"，
  dataType：" json"
      }）
      .done（功能（数据）{
alert（" success"）;
}）
      .fail（function（）{
alert（" error"）;
;}）;
$.ajax({
contentType: "application/json",
url: "https://api.projectoxford.ai/emotion/v1.0/recognize",
beforeSend: function(xhrObj){
// Request headers
xhrObj.setRequestHeader("Content-Type","application/json");
xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","************************");
},
type: "POST",
data: "{ 'url': 'http://********************' }",
dataType: "json"
})
.done(function(data) {
alert("success");
})
.fail(function() {
alert("error");
});
错误是：
推荐答案
此处存在同样的问题。执行示例JavaScript代码时，我得到：
Same issue here. When executing the example JavaScript code, I get:
选项https://api.projectoxford.ai/emotion/v1.0/recognize 404（未找到资源）
XMLHttpRequest无法加载https://api.projectoxford.ai/emotion/v1.0/recognize.
对预检请求的响应未通过访问控制检查：否'访问 - Control-Allow-Origin'&b;
标头出现在请求的资源上。因此，不允许来源"http：// localhost：7357"访问。
响应的HTTP状态代码为404.
OPTIONS https://api.projectoxford.ai/emotion/v1.0/recognize 404 (Resource Not Found)
XMLHttpRequest cannot load https://api.projectoxford.ai/emotion/v1.0/recognize.
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin'
header is present on the requested resource. Origin 'http://localhost:7357' is therefore not allowed access.
The response had HTTP status code 404.
谢谢，
