I'm new to ampscript, I would like to expose a restful service which will respond with json body. I have tried multiple sites and everywhere finding answered to hit an endpoint and read response, but not able to find ways to create and expose a restful service.
The following code will make an HTTPGet request with a header and set the response as an AMPscript variable:
<script runat="server">
Platform.Load("Core","1");
var url = "https://httpbin.org/anything";
var headerNames = ["Accept"];
var headerValues = ["application/json"];
var response = HTTP.Get(url, headerNames, headerValues);
Variable.SetValue("response",response.Content);
</script>
Response: %%=v(#response)=%%
did I understand true?

I've built many Logic Apps. I've also integrated with the Logic App API. For some reason, a Post request to an Asp.net Core Web API won't work. It works in Postman, but I can't get Logic Apps to complete the request.
The request arrives at my Web API. I can step through it during a remote debug session. I'm using the [FromBody] decorator on the API method. All the string values in the object are null.
Logic App Headers
Accept = "application/json"
ContentType = "application/json"
ContentLength = "35"
Host = "****.centralus.logic.azure.com"
API method
[HttpPost]
[Route("CreateSomething")]
public async Task<IActionResult> CreateSomething([FromBody] MyObject object)
{
//Create something great
}
I think it might have something to do with the Headers. I noticed that the Postman request won't succeed unless I check the Host and Content-Length box in the Headers section. According to this article, Logic Apps ignores those Headers.
https://learn.microsoft.com/en-us/azure/connectors/connectors-native-http
I've built the HTTP Post Action using the API as well as configured it manually using the Logic App UI in Azure.
By the way, does anyone know the Expression that will automatically calculate the ContentLength?
UPDATE:
I finally figured this out. I had to do some Ninja coding crap to make this work. I'll post my solution tomorrow.
Does anyone know how to make this work? Thanks in advance!
When you use the Logic App API to programmatically create Logic Apps, you have to specify the Body class for when you do something like an HTTP Post. When the Body JSON displayed in the designer, it contained a single object with the objects properties. My API method could not handle this. The key was to simply post the properties in the JSON Body. To make matters worse, I'm doing two HTTP Posts in this particular Logic App. When I tried to add my object properties to the existing Body class, it caused my other HTTP Post to stop working. To overcome this, I had to create a Body2 class with the objects properties. I then had to use the following line of code to replace body2 with body before adding the JSON to the Logic App API call.
This did not work.
body = new Body()
{
object = new Object()
{
//Properties
}
}
This worked.
body2 = new Body2()
{
Type = 0,
Description = "#{items('For_each_2')?['day']?['description']}",
Locations = item.Locations,
Cold = "#{items('For_each_2')?['temperature']?['cold']?['value']}",
Hot = "#{items('For_each_2')?['temperature']?['hot']?['value']}",
Hide = 0
}
Notice I used Replace on body2.
var options = new JsonSerializerOptions { WriteIndented = true, IgnoreNullValues = true};
string jsonString = ReplaceFirst(JsonSerializer.Serialize(myApp, options), "schema", "$schema").Replace("_else", "else").Replace("_foreach", "foreach").Replace("body2", "body");
I have several RESTful services that working with each other. In one scenario I want to post some data from one service to another service and I want to attach some information in Header of the request. I saw several cases to do this and in the end I came up with this workaround:
var httpClient = new HttpClient();
httpClient.Timeout = TimeSpan.FromMinutes(3);
var httpRequestMessage = new HttpRequestMessage {
Method = HttpMethod.Post,
RequestUri = new Uri(service2Address),
Content = new StringContent(JsonConvert.SerializeObject(obj))
};
httpRequestMessage.Headers.Add("myCustomHeaderKey", "myCustomHeaderValue");
var response = await httpClient.SendAsync(httpRequestMessage);
var responseString = await response.Content.ReadAsStringAsync();
With these lines of code, a Post request sent, but in service2 when I want to get the headers from request, there is no sign of myCustomHeaderKey in headers collection. I inspect Request.Headers in Visual Studio Watch and even try to get custom header with Request.Headers["myCustomHeaderKey"]. So what's wrong here?
EDIT 1
This implementation in based on this tutorial.
I have developed code like yours. Have created Two Asp.net core 3.1 project with standart template. One service is starting localhost:44320 and other localhost:44300
localhost:44320/PostService wrote the your codes.
Then get this url with browser. localhost:44320/weatherforecast/IncomeService function is like below
Finally i put breakpoint to where get request header. Result is like below
There is a not a problem. Maybe you use change request header middleware. Or if you are using something like nginx. this problem maybe nginx configuration.
I am new to windows 8. I want to call api url and the response will be return in terms of json. My Question is how to call below api url in my windows 8 code with c#.
API URL: http://scwin8dashboard.cloudapp.net/shell/~/analytics/reports/reports.ashx?fff=0&report=CampaignCategoriesOverview&languages=&sites=&startDate=20080101&endDate=20121114&addLastModified=true
please help
var uri = "http://scwin8dashboard.cloudapp.net/shell/~/analytics/reports/reports.ashx?fff=0&report=CampaignCategoriesOverview&languages=&sites=&startDate=20080101&endDate=20121114&addLastModified=true";
var client = new HttpClient();
var response = await client.GetStringAsync(uri);
var parser = JsonObject.Parse(response);
For more informations about Http requests see this page.
For JSON related classes see the Windows.Data.Json namespace.
I'm trying to exchange my authorization code for a token with the Google OAuth2 API for my Windows 8 app, but I keep getting HTTP 400 errors.
This is how I perform the request (simplified):
var url = "https://accounts.google.com/o/oauth2/token";
var body = "code=4/LEXF1iAVRZvfCfdQg9r1aFqoYDgV&client_id=904019870963.apps.googleusercontent.com&client_secret=[removed]&redirect_uri=urn:ietf:wg:oauth:2.0:oob&grant_type=authorization_code";
HttpClient httpClient = new HttpClient();
HttpResponseMessage response = await httpClient.PostAsync(new Uri(url), new StringContent(body));
response.EnsureSuccessStatusCode();
Visual Studio usually simply gives me a HTTP 400 bad request error, when I try the same thing in Fiddler I also get an HTTP 400 error, but with this as content:
21
{
"error" : "invalid_request"
}
0
I read all the documentation about Google OAuth, I searched on Google and StackOverflow for this issue, I tried changing all different sorts of things in my code (UrlEncode, etc.), I used the Google API Playground to see what kind of requests it performs and compared it with my own requests (couldn't find a difference except for the return URL, the auth code and the user-agent). No matter what I do, I just can't get this working, I've been stuck for hours already.
Can anyone help me out here?
Read the body content to get the error json you noticed in Fiddler.
HttpClient httpClient = new HttpClient();
var response = httpClient.PostAsync(new Uri(url), new StringContent(body)).Result;
var content = response.Content.ReadAsStringAsync().Result;
content now holds :
{
"error" : "invalid_request"
}
You could project the error in an object, by specifing your error type like: response.Content.ReadAsAsync().Result
For the invalid request part, you should play with UrlEncode. I know you say you tried it, but applying it at the right spots really solves your problem.
var body = "code="+WebUtility.UrlEncode("4/LEXF1iAVRZvfCfdQg9r1aFqoYDgV")+
"&redirect_uri="+WebUtility.UrlEncode("https://yoursite...")+
"&client_id=904019870963.apps.googleusercontent.com" +
"&scope=" +
"&client_secret=********" +
"&grant_type=authorization_code";
HttpClient httpClient = new HttpClient();
var response = httpClient.PostAsync(new Uri(endpoint),
new StringContent(body, Encoding.UTF8, "application/x-www-form-urlencoded")).Result;
This is the code that works for me. Should work for you also.
I use this simple way to attach username and password to the SOAP request header. This works fine inside Java boundaries, but I want to be able to call it with my WCF client. How do I do this?
I've tried the following code, but it does not include the credentials in the header:
wsClient.ClientCredentials.UserName.UserName = "Hello";
wsClient.ClientCredentials.UserName.Password = "World";
Thanks in advance!
That is quite awful non-standardized way. It uses custom HTTP Headers so you cannot expect that built in WCF mechanism will magically support such approach. How should WCF know that you want to add custom non-standard HTTP header to HTTP request (not SOAP header)?
Use this:
var proxy = new YourServiceClient();
using (var scope = new OperationContextScope(proxy.InnerChannel))
{
var prop = new HttpRequestMessageProperty();
prop.Headers.Add("UserName", "Hello");
prop.Headers.Add("Password", "World");
OperationContext context = OperationContext.Current;
context.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = prop;
proxy.CallYourOperation();
}
