我正在尝试使用工厂模式进行同步调用。
$scope.doLogin = function (username, password, rememberme) {
appKeyService.makeCall().then(function (data) {
// data = JSON.stringify(data);
debugAlert("login controller app key service"+data);
var appkeyvalue = data.d.appkey;
sessionConfigurationService.setBasicToken(appkeyvalue);
loginService.makeCall(username, password, rememberme).then(function (accessTokenData) {
if (accessTokenData.access_token !== "")
{
sessionConfigurationService.setAccessTokenData(accessTokenData.access_token);
userPreferencesService.makeCall().then(function (userPreferencesData) {
if (userPreferencesData.d.userId !== "")
{
sessionConfigurationService.setUserPreferences(userPreferencesData.d);
// $window.location.href = '/base.html';
}
});
}
});
});
};
我的appKeyService工厂
app.factory('appKeyService', function ($q, authenticatedServiceFactory, configurationService) {
var deffered = $q.defer();
var service = {};
service.makeCall = function () {
debugAlert("appKeyService async method request start");
authenticatedServiceFactory.makeCall("GET", configurationService.getAppKeyURL(), "", "").then(function (data) {
debugAlert("appKeyService async method response")
deffered.resolve(data);
});
return deffered.promise;
};
return service;
});
我认证的服务工厂
app.factory('authenticatedServiceFactory', function ($http, $q, sessionConfigurationService) {
var deffered = $q.defer();
var service = {};
service.makeCall = function (methodType, URL, data, authType) {
var headerValue = "";
if (authType === "Basic") {
headerValue = sessionConfigurationService.getBasicToken();
} else if (authType === "Bearer") {
headerValue = sessionConfigurationService.getBearerToken();
}
var config = {headers: {
'Authorization': headerValue,
'Accept': 'application/json;odata=verbose',
},
withCredentials: true,
async: false
};
if (methodType === "GET") {
$http.get(URL, data, config)
.then(function (getData) {
debugAlert("GET method response" + JSON.stringify(getData));
deffered.resolve(getData.data);
}, function (error) {
debugAlert("GET method response error" + JSON.stringify(error));
deffered.reject(error);
});
}
else if (methodType === "POST") {
$http.post(URL, data, config)
.then(function (putData) {
debugAlert("POST method response" + JSON.stringify(putData));
deffered.resolve(putData.data);
}, function (error) {
debugAlert("POST method response error" + JSON.stringify(error));
deffered.reject(error);
});
}
else if (methodType === "DELETE") {
$http.delete(URL, data, config)
.then(function (deleteData) {
debugAlert("DELETE method response" + JSON.stringify(deleteData));
deffered.resolve(deleteData.data);
}, function (error) {
debugAlert("DELETE method response error" + JSON.stringify(error));
deffered.reject(error);
});
}
else if (methodType === "PUT") {
$http.put(URL, config)
.then(function (putData) {
debugAlert("PUT method response" + JSON.stringify(putData));
deffered.resolve(putData.data);
}, function (error) {
debugAlert("PUT method response error" + JSON.stringify(error));
deffered.reject(error);
});
}
return deffered.promise;
};
return service;
});
但我没有看到服务调用是同步的。所以控制器中的“then”部分在之后没有执行我们收到响应。它一个接一个地执行。我怎样才能做到这一点。

感谢您的评论。我带来了
var deffered = $q.defer();
在makeCall方法中,它现在正如我所希望的那样工作。谢谢!
app.factory('appKeyService', function ($q, authenticatedServiceFactory, configurationService) {
var service = {};
service.makeCall = function () {
var deffered = $q.defer();
debugAlert("appKeyService async method request start");
authenticatedServiceFactory.makeCall("GET", configurationService.getAppKeyURL(), "", "").then(function (data) {
debugAlert("appKeyService async method response")
deffered.resolve(data);
});
return deffered.promise;
};
return service;
});
