大佬教程收集整理的这篇文章主要介绍了在AngularJS 1.0.7中使用$ resources嵌套诺言，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
您可以$promise从函数中的BoatType资源返回资源，parseBoatTime并使用Promise来解决parseUrl延迟的问题。
首先从parseBoatTime函数返回一个promise ：
return BoatType.getBoatTypeByname({
name: boatTypeParsed
}, function success(result) {
return result;
}).$promise;
然后parseUrl deferred用BoatType资源中的承诺解决：
parseBoatType().then(deferred.resolve);
贝娄是从您的问题中得到的完整代码，我提到了更正。
var parseURL = function() {
var deferred = $q.defer();
var promise = deferred.promise;
promise.then(function success(result) {
console.log(result);
searchBoats(result);
});
parseBoatType().then(deferred.resolve);
};
parseURL();
var parseBoatType = function() {
// Do some stuff
// Calculate boatType calling a service that uses resource to call
// an API
// I can convert this callback into a promise but still facing same
// issue
// Code for ngResource@^1.2.0
/*return BoatType.getBoatTypeByname({
name: boatTypeParsed
}, function success(result) {
return result;
}).$promise;*/
// Code for ngResource lower than 1.2.0
var deferred = $q.defer(), promise = deferred.promise;
BoatType.getBoatTypeByname({
name: boatTypeParsed
}, deferred.resolve, deferred.reject);
return promise;
// The service method is called and the code is still running until
// the end of the function without waiting for the service result.
// Then the promise.then code in the parseURL is executed and
// searchBoats is run with boatType undefined.
};
// The service with the $resource call to the API
app.factory('BoatType',
function($resource, SERVER_URL) {
var boatTypes =
$resource('http://' + SERVER_URL + '/:action', {
action: 'boat_types'
}, {
query: {
method: 'GET',
isArray: true
},
getBoatTypeByname: {
method: 'GET',
params: {
action: 'getBoatTypeByname'
},
isArray: false
}
});
return boatTypes;
}
)
我需要在AngularJS 1.0.7中使用参数运行函数 “ searchBoats（boatType）” 。此参数是另一个函数
parseBoatType 的结果，该函数 正在运行使用$ resource调用API的服务
。当带有诺言的资源中返回boatType时，如何运行searchBoats？
这是我尝试的：
var parseURL = function() {
var deferred = $q.defer();
var promise = deferred.promise;
promise.then(function success (result) {
console.log(result);
searchBoats(result);
});
deferred.resolve(
parseBoatType()
);
};
parseURL();
var parseBoatType = function() {
// Do some stuff
// Calculate boatType calling a service that uses resource to call
// an API
// I can convert this callback into a promise but still facing same
// issue
BoatType.getBoatTypeByName({name: boatTypeParsed},function success(result) {
return result;
});
// The service method is called and the code is still running until
// the end of the function without waiting for the service result.
// Then the promise.then code in the parseURL is executed and
// searchBoats is run with boatType undefined.
};
// The service with the $resource call to the API
.factory('BoatType',function($resource,SERVER_URL){
var boatTypes =
$resource('http://' + SERVER_URL +'/:action',{action:'boat_types'},{
query: {method:'GET',isArray: true},getBoatTypeByName: {method:'GET',params:{action: 'getBoatTypeByName'},isArray: false}
});
return boatTypes;
}
)
