嗨,当我尝试从我的服务器/本地计算机通过 JavaScript 访问 Microsoft Cognitive Services API 时,我收到以下错误。
XMLHttpRequest cannot load http://api.projectoxford.ai/vision/v1.0/analyze?visualFeatures=Categories. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myUrl.com' is therefore not allowed access. The response had HTTP status code 401.
这是我的请求代码:
function requestAPI(){
var params = {
// Request parameters
"visualFeatures": "Categories"
};
$.ajax({
url: "http://api.projectoxford.ai/vision/v1.0/analyze?" + $.param(params),
beforeSend: function(xhrObj){
// Request headers
xhrObj.setRequestHeader("Content-Type","application/json");
xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","{myKey}");
},
type: "POST",
// Request body
data: "{'url':'http://www.html5canvastutorials.com/demos/assets/darth-vader.jpg'}",
})
.done(function(data) {
alert("success");
})
.fail(function() {
alert("error");
});
}
在我的 .htaccess 中,我已经添加了:
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
当我用 hurl.it 测试请求时,它可以工作。只是从我的服务器它没有。
