角度中的單個請求在節點上顯示兩個請求,一個使用x-auth-token作爲未定義,另一個使用令牌。
由於在我的角度前端(附加屏幕截圖)中出現以下錯誤,最終我深入瞭解了節點。
角代碼:
var self = this;
var $http = angular.injector(["ng"]).get("$http");
var authToken = localStorage.getItem("authToken") ? localStorage.getItem("authToken") : Config.authToken;
$http.defaults.headers.common["X-Auth-Token"] = authToken;
$http.get(Config.url)
.success(function(data, status, headers, config) {
self.onResult(data);
})
.error(function(data, status, headers, config) {
console.log(data); //this is empty
console.log(status); //stauts is 0
console.log(headers);
console.log(config);
self.onFault(data);
});
Node.js的
var self = this;
app.use(function(request, response, next){
response.set("X-Powered-By", "FIC");
response.header("Access-Control-Allow-Origin", "*");
response.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token");
request.id = self.id++;
console.log(request.id, request.url, request.headers['x-auth-token']);
next();
});

你能也記錄HTTP方法?如果這是一個不同的主機,瀏覽器很可能會在實際的GET – David 2014-11-04 19:32:58
之前發出一個OPTIONS請求,請參閱預衝的請求https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Preflighted_requests – David 2014-11-04 19:34:18
是的它是OPTIONS - >'0'/attendees?appId=ag.cas.fic''OPTIONS'undefined'但是問題是爲什麼角度最後是狀態0的'error'函數調用,我應該記錄'response'輸出的結束? – user2727195 2014-11-04 19:36:03
