angularjs 1.59
此API调用可用于$http.get
。
JS ViewModel
$scope.placeOrder = function () { //'api/order/create'
var order = { AccountId : accountId, Amount : $scope.subTotal,
Tax: $scope.tax, Shipping: $scope.shipping }
var orderJSON = JSON.stringify(order);
viewModelHelper.apiGet('api/order/create', { params: { order: orderJSON } },
function (result) {
var orderId = result.data;
});
}
app.js
self.apiGet = function (uri, data, success, failure, always) {
self.isLoading = true;
self.modelIsValid = true;
$http.get(AlbumApp.rootPath + uri, data)
.then(function (result) {
success(result);
if (always != null)
always();
self.isLoading = false;
}, function (result) {
if (failure == null) {
if (result.status != 400)
self.modelErrors = [result.status + ': ' + result.statusText +
' - ' + result.data];
else
self.modelErrors = [result.data + ''];
self.modelIsValid = false;
}
else
failure(result);
if (always != null)
always();
self.isLoading = false;
});
}
self.apiPost = function (uri, data, success, failure, always) {
self.isLoading = true;
self.modelIsValid = true;
$http.post(AlbumApp.rootPath + uri, data)
.then(function (result) {
success(result);
if (always != null)
always();
self.isLoading = false;
}, function (result) {
if (failure == null) {
if (result.status != 400)
self.modelErrors = [result.status + ': ' + result.statusText + ' - ' + result.data];
else self.modelErrors = [result.data];
self.modelIsValid = false;
}
else failure(result);
if (always != null) always();
self.isLoading = false;
});
}
apicontroller
[HttpGet]
[Route("create")]
public IHttpActionResult Create(string order) {
var _order = JsonConvert.DeserializeObject<Order>(order); ... }
,但是由于这是一个创建函数,所以我想使用$http.post
。当我更改
$scope.placeOrder = function () { //'api/order/create'
var order = { AccountId : accountId, Amount : $scope.subTotal,
Tax: $scope.tax, Shipping: $scope.shipping }
var orderJSON = JSON.stringify(order);
viewModelHelper.apiPost('api/order/create', { params: { order: orderJSON } },
//null,
function (result) {
var orderId = result.data;
});
}
和我的控制器动作
[HttpPost]
[Route("create")]
public IHttpActionResult Create(string order) {
var _order = JsonConvert.DeserializeObject<Order>(order); ... }
我有404错误:
<Error>
<Message>
No HTTP resource was found that matches the request URI 'http://localhost:50597/api/order/create'.
</Message>
<MessageDetail>
No action was found on the controller 'OrderApi' that matches the request.
</MessageDetail>
</Error>
这是一个错误还是我错过了一些概念上的点,还是我的代码中有错误?
解决方案:(谢谢Giovani(
params:
需要传递给$http.get
和$http.post
中的config
。这两种方法具有不同的签名。
在apiGet
中,将data
重命名为config
。在apiPost
中添加了config
。
在apiPost
中添加了null
,因此params:
传递给config
而不是data
。
app.js
self.apiGet = function (uri, config, success, failure, always) {
self.isLoading = true;
self.modelIsValid = true;
$http.get(AlbumApp.rootPath + uri, config)
...
self.apiPost = function (uri, data, config, success, failure, always) {
self.isLoading = true;
self.modelIsValid = true;
$http.post(AlbumApp.rootPath + uri, data, config)
JS ViewModel
$scope.placeOrder = function () { //'api/order/create'
var order = { AccountId : accountId, Amount : $scope.subTotal,
Tax: $scope.tax, Shipping: $scope.shipping }
var orderJSON = JSON.stringify(order);
viewModelHelper.apiPost('api/order/create', null, { params: { order: orderJSON } },
function (result) {
var orderId = result.data;
}); }
$ http.get((和$ http.post((具有不同的方法签名。更多信息
$http.get(<URL>, <DATA (params, responseType, etc..)>)
$http.post(<URL>, <BODY_DATA>, <DATA (params, responseType, etc..)>
