angularJs – 405方法不允许在WebAPI2(OWIN)（angularjs表达式中不能使用的运算符）
webAPI和Angular位于不同的站点上。
在Startup.cs我有：
public void Configuration(IAppBuilder app)
{
ConfigureOAuth(app);
var config = new HttpConfiguration();
WebApiConfig.Register(config);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWebApi(config);
}
private void ConfigureOAuth(IAppBuilder app)
{
var oAuthServerOptions = new OAuthAuthorizationServerOptions
{
AllowInsecureHttp = true,TokenEndpointPath = new PathString(Paths.TokenPath),AccesstokenExpireTimeSpan = TimeSpan.FromMinutes(30),Provider = Kernel.Get<IOAuthAuthorizationServerProvider>()
};
app.USEOAuthAuthorizationServer(oAuthServerOptions);
OAuthBearerOptions = new OAuthBearerAuthenticationoptions();
app.USEOAuthBearerAuthentication(OAuthBearerOptions);
}
然后在控制器上，我的方法设置为允许匿名：
[AllowAnonymous]
public bool PostRegister(UserSignupForm form)
{
...
}
我也更新了web.config：
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONsverbHandler" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
在角度方面，我做了一个简单的$ http.post调用：
saveRegistration: function (registration) {
return $http.post(baseUrl + '/api/signup/register',registration).then(function (response) {
return response;
});
}
当使用Postman进行调用时，我得到了一个成功的响应，但是当从Angular进行相同的调用时，我得到了405错误。
BitOfTech示例站点正在发送相同的请求标头，但能够获取Access-Control-Allow-XXX标头
我已经更新了我的代码以跟随Token Based Authentication using ASP.NET Web API 2,Owin,and Identity
[AllowAnonymous]
[Route("Register")]
[AcceptVerbs("OPTIONS")]
public async Task<IHttpActionResult> Register()
{
return Ok();
}
angularjs – Angular 1.2不再允许在同一个元素上使用多个隔离的范围指令？
这在1.0中工作,但是Angular 1.2现在在尝试执行此操作时会生成错误
Multiple directives asking for new/isolated scope
基于项目git历史出现Angular 1.2更改行为,以保持两个隔离的指令在同一元素上分开.这是一件好事,当在同一元素上放置两个“Attribute”指令时,它可以正常工作.
即
<div my:directive="myDirectiveData" my:other-directive="myOtherDirectiveData" />
像你期望的那样工作.
然而
<my:directive my:directive-data="myDirectiveData" my:other-directive="myOtherDirectiveData" />
引发上述错误. (多个指令要求新/隔离范围)
在这种情况下,我希望每个指令仍然与它们自己的非共享隔离范围并行存在.
这在Angular 1.2中仍然可行吗？
Scenario directive #1 directive #2 Result
1 no new scope no new scope Both directives use the controller's scope.
(This should be obvIoUs.)
2 new scope new scope Both directives share one new child scope.
3 new scope no new scope Both directives share one new child scope.
Why does dir #2 use the child scope?
This seems odd to me.
4 isolate scope no new scope Angular v1.0: both directives share the
isolate scope.
Angular v1.2+: dir #1 uses the isolate scope,dir #2 uses the controller's scope.
请注意,不允许以下方案(Angular引发错误)：
Scenario directive #1 directive #2
5 isolate scope new scope
6 isolate scope isolate scope
angularjs – Angular JS MVC Web API模型/参数不绑定.NET Core
我有一个apiService来处理对服务器的所有POST和GET请求,如下所示：
module TBApp {
export class apiService {
static $inject = ['$http','notificationService'];
constructor(private $http,private notificationService: notificationService) {
}
get(url,config,success,failure) {
return this.$http.get(url,config)
.then(result => { this.handleResponse(result,success); },result => { this.handleError(result,failure) });
}
post(url,data,failure) {
return this.$http.post(url,data)
.then(result => { this.handleResponse(result,failure) });
}
handleResponse(result,success) {
alert('success');
success(result);
}
handleError(result,failure) {
if (result.status === '401') {
this.notificationService.displayError('Authentication required.');
//this.$rootScope.prevIoUsstate = this.$location.path();
//this.$location.path('/login');
}
else if (failure !== null) {
failure(result);
}
}
}
}
现在,当我发送此请求时：
onCompanyChanged(selectedCompany,model,companyName) {
this.apiService.post('/api/Dashboard/GetAssetListByCompany',{ companyId: selectedCompany.id },response => {
this.assetListviewmodel = response.data.data;
},response => {
this.notificationService.displayError(response.data.message);
});
}
它没有绑定控制器中的companyId
这是控制器：
[Route("api/[controller]")]
public class DashboardController : BaseController
{
[HttpPost]
[Route("GetAssetListByCompany")]
public IActionResult GetAssetListByCompany([FromBody]int companyId)
{
return CreateJsonResult(() =>
{
if (companyId == 0) { return new xPTJsonResult(null,xPTStatusCodesEnum.Success,"Company Id is 0"); }
//var treeModel = _dashboardProvider.GetTreeModelByCompany(companyId,usermodel);
return new xPTJsonResult(null,"Loaded assets successfully");
});
}
}
即使我在浏览器中检查了请求,也表明companyId在Payload中.
NOTE: The same function works when I post a viewmodel
编辑
在上面的场景中,我只将一个参数传递给控制器,但在某些情况下,我希望能够在不使用viewmodel的情况下传递2或3个参数.
例如
public IActionResult GetAssetListByCompany([FromBody]int companyId,[FromBody]int assetId)
{....
要么
public IActionResult GetAssetListByCompany([FromBody]int companyId,[FromBody]int assetId,[FromBody]bool canEdit = false)
{.....
然后在客户端我可以这样做：
this.apiService.post('/api/Dashboard/GetAssetListByCompany',{ companyId: selectedCompany.id,assetId: 123 }.....
要么
this.apiService.post('/api/Dashboard/GetAssetListByCompany',canEdit: true,assetId: 22 }....
解决方法
MVC改变了
有关各种选项,请参阅Model Binding,此处的最佳方法是基于查询字符串进行绑定,因为您只需要一个基本类型.如果您有一个基本类型数组仍然可以绑定到查询字符串,则查询字符串变量名称将为每个值重复一次.
因此,我们所做的唯一更改是指定参数来自查询字符串,并且它与Http Get请求而不是Post相关联.
[Route("api/[controller]")]
public class DashboardController : BaseController
{
[HttpGet] // change to HttpGet
[Route("GetAssetListByCompany")]
public IActionResult GetAssetListByCompany([FromQuery]int companyId) // use FromQuery
{
return CreateJsonResult(() =>
{
if (companyId == 0) { return new xPTJsonResult(null,"Company Id is 0"); }
//var treeModel = _dashboardProvider.GetTreeModelByCompany(companyId,usermodel);
return new xPTJsonResult(null,"Loaded assets successfully");
});
}
}
AngularJS发生了变化
我们扩展apiService以允许使用HttpGet传递调用数据.这可以使用params on the $http call完成,它将使用名称作为查询字符串值名称和值作为值部分,根据传入的数据动态创建URL.
export class apiService {
/* all other code is left as is,just change the get method to also accept data via the params. If null is passed in then it is ignored. */
get(url,failure) {
return this.$http({
url: url,config: config,params: data,method: "GET"
})
.then(result => { this.handleResponse(result,failure) });
}
}
在通话中我们只需要从post更改为get,它应该可以工作.
// only change from post to get
onCompanyChanged(selectedCompany,companyName) {
this.apiService.get('/api/Dashboard/GetAssetListByCompany',response => {
this.assetListviewmodel = response.data.data;
},response => {
this.notificationService.displayError(response.data.message);
});
}
编辑 – 这很灵活
更重要的是,这种设计在角度方面是灵活的.如果您扩展MVC操作或具有采取其他参数的各种操作,则无需执行任何其他更改即可运行.例：
[HttpGet]
[Route("GetSomethingElseFromServer")]
public IActionResult GetSomethingElseFromServer([FromQuery]int companyId,[FromQuery]string assetName,[FromQuery]string companyModelNumber) // use FromQuery
对你的角度api的调用将是
this.apiService.get('/api/Dashboard/GetSomethingElseFromServer',{ companyId: companyId,assetName: somePassedInAssetNameVar,companyModelNumber: somePassedInModelNumber }
编辑 – 您也可以发送数组
要回答关于如何将多个基元类型作为数组发送的问题,您可以这样做.同样,这假设它不是您要发送的复杂类型,但是,例如,公司ID列表.
c#代码
[HttpGet]
[Route("GetAssetListByCompany")]
public IActionResult GetAssetListByCompany([FromQuery]int[] companyIds) // use an array of int ie. int[]. i changed the variable name to make it clear there can be more than 1
Angular调用,注意没有必要更改服务
onCompanyChanged(selectedCompany,{ "companyIds[]": [id1,id2,id3] },// note the name is Now enclosed in quotes,made plural,and includes []. The value is an array
response => {
this.assetListviewmodel = response.data.data;
},response => {
this.notificationService.displayError(response.data.message);
});
}
编辑 – 如果你想要POST
您目前只发送一个原始字段,因此POST中的MVC框架无法正确反序列化.您需要将参数包装在视图模型中,将其作为查询字符串部分发送,或将其作为表单字段值发送.这是带有查询字符串部分的POST,它可以正常工作.
选项1
将其附加到URL
[HttpPost] // change to HttpGet
[Route("GetAssetListByCompany")]
public IActionResult GetAssetListByCompany([FromQuery] int companyId) // use FromQuery
角度呼叫
this.apiService.post('/api/Dashboard/GetAssetListByCompany/?companyId=' + selectedCompany.id +,null,// the rest of the code remains unchanged so I did not include it
选项2
扩展apiService以获取params对象,以便它可以构建您的查询.无论哪种方式,你都会遇到调用者不得不对http调用有所了解.
this.apiService.post('/api/Dashboard/GetAssetListByCompany',{companyId: selectedCompany.id},// the rest of the code remains unchanged so I did not include it
post(url,params,failure) {
return this.$http({
url: url,data: data,params: params,method: "POST"
})
.then(result => { this.handleResponse(result,failure) });
}
选项3
更新视图模型以采用复杂类型,这不需要更改角度代码.
public class ListByCompanyModel {
public int CompanyId {get;set;}
}
[HttpPost] // change to HttpGet
[Route("GetAssetListByCompany")]
public IActionResult GetAssetListByCompany([FromBody] ListByCompanyModel model) // use FromQuery
angularjs – Angular POST to Web API不传递数据
我正在发布一个方法,该方法将返回系统中实体的一些搜索结果.它看起来像这样：
public IEnumerable<dynamic> Post(string entity,FormDataCollection parameters)
{
// entity is passed on the route.
// parameters contains all the stuff I'm trying to get here.
}
如果我使用jQuery.post调用该方法：
$.post('api/search/child',{where : 'ParentID = 1'},function(d){ foo = d });
它运作正常,并返回我期望的.
我在我的角度应用程序中提供了一个类似的调用服务：
$http.post('api/search/child',{ where: 'parentID = ' + parent.ID })
.success(function (data,status,headers,config) {
// etc.
})
但是当它在服务器上点击我的“Post”方法时,“paramters”为空.
经过一些谷歌搜索后,我尝试添加一个内容类型的标题,以确保它作为JSON传递,并尝试JSON.stringify-ing和$.param() – “数据”参数,但没有做任何事情(和从我所读到的那些不应该是必要的.)我在这里做错了什么？谢谢你的帮助！
更新：
这是来自(工作)jQuery示例的原始请求：
POST http://localhost:51383/api/search/child HTTP/1.1 Accept: */* Content-Type: application/x-www-form-urlencoded; charset=UTF-8 X-Requested-With: XMLHttpRequest Referer: http://localhost:51383/mypage.aspx Accept-Language: en-US Accept-Encoding: gzip,deflate User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko Host: localhost:51383 Content-Length: 23 DNT: 1 Connection: Keep-Alive Pragma: no-cache Cookie: (etc) Authorization: (etc) where=ParentID+%3D+1
来自(失败的)Angular样本的原始请求：
POST http://localhost:51383/api/search/parent HTTP/1.1
Content-Type: application/json;charset=utf-8
Accept: application/json,text/plain,*/*
Referer: http://localhost:51383/mypage.aspx
Accept-Language: en-US
Accept-Encoding: gzip,deflate
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
Connection: Keep-Alive
Content-Length: 27
DNT: 1
Host: localhost:51383
Pragma: no-cache
Cookie: (etc)
{"where":"scorecardID = 1"}
很奇怪.即使我将’json’数据类型参数添加到jQuery调用的末尾,它仍然会创建www-form-urlencoded请求.那是有效的.我的Web API应用程序已经为JSON设置(但感谢Dalorzo).
解决方法
System.Web.Http.GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
config.Formatters.Insert(0,new System.Net.Http.Formatting.JsonMediaTypeFormatter());
只有设置了正确的格式化程序,Content-Type = application / json才有效.
您也可以尝试在参数类型旁边使用[FromBody].
angularjs – Angular – > Web Api 2：“没有’Access-Control-Allow-Origin’标题”
我已将我的CORS属性添加到我的WebApiConfig类：
public static void Register(HttpConfiguration config)
{
var cors = new EnableCorsAttribute("http://localhost:51407","*","*");
config.EnableCors(cors);
但是每当我发送一个正确包含的Ajax请求(使用angularJS)时
Origin: http://localhost:51407
我收到错误：
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:51407' is therefore not allowed access.
可能是什么问题？
解决方法
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="your_clientWebUrl" />
</customHeaders>
</httpProtocol>
</system.webServer>
