I am trying to send data from API to web service. But it is always receiving null
Code in API - WEB CLIENT:
using (var webClient = new WebClient())
{
webClient.Headers[HttpRequestHeader.ContentType] = "application/json";
var url = string.Format("End Point URL /SomeAction");
var user= new User()
{
...
};
var data = JsonConvert.SerializeObject(user);
webClient.UploadString(url, data);
}
Service:
public ActionResult SomeAction([System.Web.Http.FromBody]string data)
{
JavaScriptSerializer json_serializer = new JavaScriptSerializer();
FOUsers dataFromXBO =
(FOUsers)json_serializer.DeserializeObject(data);
//statements
}
Please advice, How can i receive data that passed from API
To answer your question directly, to extract a string from a request body, wrap your "string" in another object as per this SO link. ie.
class UserPostRequest{
public string UserJson{get; set;}
}
And change the signature in your controller as follows:
public ActionResult SomeAction([System.Web.Http.FromBody]UserPostRequest data)
With that said, in this specific instance it's likely that you can just do:
public ActionResult SomeAction([System.Web.Http.FromBody]FOUsers data)
and let the API take care of deserialization for you.
EDIT:
After further research, to add completeness to the first half of my answer let me acknowledge that there are many ways to skin that particular cat. The answer provided is just the one I've historically used. Here's another SO post that enumerates other solutions, including accepting a dynamic or HttpRequestMessage in your API method signature. These would be particularly helpful if for some reason you didn't want to change your client code. That said, again, I don't see a particular reason to do manual serialization if you're just going to end up consuming the out-of-the-box functionality.

I'm using for the first time Web Services, and when I try to consume it, I have this error:
NotSupportedException: Cannot serialize interface
I tried changing the configuration names or adding [XmlSerialize] but is not working...
What should I do to avoid this?
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
EndpointAddress endpoint =
new EndpointAddress("myendpoint")
client.ClientCredentials.UserName.UserName = _userName;
client.ClientCredentials.UserName.Password = _password;
SoapClient client = new SoapClient(binding, endpoint);
using (new OperationContextScope(client.InnerChannel)) --> here I have the problem
{
//My code
}

Is there a way to calculate lines of code in a Pull Request API in Azure Devops for each file. I have gone through below two links and but was not of much help.
Is there a way to get the amount of lines changed in a Pull Request via the Dev Ops Service REST API?
Lines of Code modified in each Commit in TFS rest api. How do i get?
Thank you.
Steps:
a. Get the commit IDs for the specified pull request
GET https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/pullRequests/{pullRequestId}/commits?api-version=6.1-preview.1
b. Get commit path via the commit ID
GET https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/commits/{commitId}/changes?api-version=5.0
c. Get parents commit ID via commit ID
GET https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/commits/{commitId}?api-version=5.0
d. Get the result via below API and request body.
POST https://dev.azure.com/{Org name}/_apis/Contribution/HierarchyQuery/project/{Project name}?api-version=5.1-preview
Request Body:
{
"contributionIds": [
"ms.vss-code-web.file-diff-data-provider"
],
"dataProviderContext": {
"properties": {
"repositoryId": "{Repo ID}",
"diffParameters": {
"includeCharDiffs": true,
"modifiedPath": "{Commit path}",
"modifiedVersion": "GC{Commit ID}",
"originalPath": "{Commit path}",
"originalVersion": "GC{parents commit ID}",
"partialDiff": true
}
}
}
}

All my REST API methods start with that code as follows:
[HttpPost]
[Route("Login")]
public async Task<IHttpActionResult> Login(QueryModel q)
{
// get JWT Token string form HTTP Header
string token = Request.Headers.GetValues("Authorization").FirstOrDefault();
// decode token
string json = Jose.JWT.Decode(token, JWTModel.secretForAccessToken);
JWTModel jwt = JsonConvert.DeserializeObject<JWTModel>(json);
// check if issued from my homepage.
if (!jwt.iss.Equals("my-home-page.com"))
{
return Content(
HttpStatusCode.Unauthorized,
"access token is not from here"
);
}
// check if it has valid about time
long now = (long)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds;
if (jwt.iat > now || jwt.exp < now)
{
// request refresh token
return Content(
HttpStatusCode.Unauthorized,
"outdated access token"
);
}
/* ... */
}
How ridiculous and redundant are they!
Can I simplify and modulize them? And How?
(In Node.js, I can solve it by using so called middleware.)
I would suggest you look at DelegatingHandler or if you are running an OWIN based application then you can create Middleware

I created a web api using C# and also created a mobile application using cordova.
I am retrieving all data on cordova app using JSON.
Now I want to save this JSON data to client side. Please suggest me the best option to save all the data to client side.
SQLLite
websql
JSON file directly saved to client side or other option.
If you need to keep your client-side and server-side DBs in sync, PouchDB is a good choice - you can use pouchdb-phonegap-cordova to implement it in the app. You'd also need implement a CouchDB REST interface on the server-side.
Or since your data is already formatted as JSON, you may want to try cordova-sqlite-porter as a convenient way to store the data - it will interface with either the WebView's WebSQL DB or native SQLite in conjunction with Cordova-sqlite-storage plugin.
You can pass your data as a JSON structure to importJsonToDb() which makes optimisations to perform the operation as fast as possible. This is good if you have a large amount of data to insert. Example usage:
var db = window.openDatabase("Test", "1.0", "TestDB", 1 * 1024);
var json = {
"structure":{
"tables":{
"Artist":"([Id] PRIMARY KEY, [Title])"
},
"otherSQL": [
"CREATE UNIQUE INDEX Artist_ID ON Artist(Id)"
]
},
"data":{
"inserts":{
"Artist":[
{"Id":"1","Title":"Fred"},
{"Id":"2","Title":"Bob"},
{"Id":"3","Title":"Jack"},
{"Id":"4","Title":"John"}
]
}
}
};
var successFn = function(count){
alert("Successfully imported JSON to DB; equivalent to "+count+" SQL statements");
};
var errorFn = function(error){
alert("The following error occurred: "+error.message);
};
var progressFn = function(current, total){
console.log("Imported "+current+"/"+total+" statements";
};
cordova.plugins.sqlitePorter.importJsonToDb(db, json, {
successFn: successFn,
errorFn: errorFn,
progressFn: progressFn,
batchInsertSize: 500
});
You can use pouchdb no SQL database here, also you can use cordova sqlite plugin here.

I am trying to connect to the Stack Overflow API as one of my first api calls, but I am struggling.
Can someone tell me why this code does not return a success code?
using (var handler = new HttpClientHandler())
using (var client = new HttpClient(handler))
{
client.BaseAddress = new Uri("https://api.stackexchange.com/");
var response = await client.GetAsync("questions");
if (response.IsSuccessStatusCode)
{
}
else
{
Console.WriteLine(response.ToString());
}
}
The response tells you site is required. Hit https://api.stackexchange.com/questions?site=stackoverflow instead.
You're getting back
{"error_id":400,"error_message":"site is required","error_name":"bad_parameter"}
If you read the error and documentation, it needs to know which StackExchange site you want. Try:
https://api.stackexchange.com/questions?site=stackoverflow
