I am trying to post data to Power Automate HTTP Request trigger, but i just get all properties with Null values. I dont know what i am missing?
It is requeried to set "Content-Type":"application/json".
(blog post referecne: https://flow.microsoft.com/en-us/blog/call-flow-restapi/ )
My .Net corre app code is:
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("Content-Type", "application/json");
var response = await client.PostAsJsonAsync(url, order);
response.EnsureSuccessStatusCode();
var data = await response.Content.ReadAsAsync<String>();
http post data
I test it in my side, you can refer to my power-automate flow and my .net code below:
My flow shown as:
And my code shown as below:
using System;
using System.Net.Http;
using System.Text;
namespace ConsoleApp7
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
var postData = "{\"name\": \"Hury\",\"email\": \"test#xxx.com\"}";
HttpContent httpContent = new StringContent(postData, Encoding.UTF8, "application/json");
HttpClient client = new HttpClient();
var response = client.PostAsync("your http request trigger url", httpContent);
Console.WriteLine(response.Result);
}
}
}
After running this code, we can see the properties are post success from the request in the running history.

In my Blazor Client project, I have the following code:
#using Microsoft.AspNetCore.JsonPatch
...
var doc = new JsonPatchDocument<Movie>()
.Replace(o => o.Title, "New Title");
await Http.PatchAsync("api/patch/" + MovieId, doc);
This won't compile with the following error:
Error CS1503 Argument 2: cannot convert from
'Microsoft.AspNetCore.JsonPatch.JsonPatchDocument'
to 'System.Net.Http.HttpContent'
After some research, I've installed Newtonsoft.Json but I'm unsure how to configure the project to use it, or if indeed this is the correct solution for getting JsonPatchDocument working in a Blazor Project?
If JsonPatchDocument is not supported by Blazor, how can I implement a HTTP Patch request?
I just had a different but related issue. You are correct that you need to be using Newtonsoft.Json instead of System.Text.Json on the client application. Here is an extension method that will turn your JsonPatchDocument into an HttpContent.
public static class HttpClientExtensions
{
public static async Task<HttpResponseMessage> PatchAsync<T>(this HttpClient client,
string requestUri,
JsonPatchDocument<T> patchDocument)
where T : class
{
var writer = new StringWriter();
var serializer = new JsonSerializer();
serializer.Serialize(writer, patchDocument);
var json = writer.ToString();
var content = new StringContent(json, Encoding.UTF8, "application/json-patch+json");
return await client.PatchAsync(requestUri, content);
}
I know it's late but I hope it's helpful.
I want to accomplish this, is there any trick
HttpClient c = new HttpClient();
c.DefaultRequestHeaders.Add("Content-type", "application/octet-stream"));
You should set content headers with HttpContent object, like below.
var client = _clientFactory.CreateClient();
using (var content = new ByteArrayContent(byteData))
{
content.Headers.ContentType =
new MediaTypeHeaderValue("application/octet-stream");
var response = await client.PostAsync(uri, content);
//code logic here
//...
}
Besides, for more information about using IHttpClientFactory to create an HttpClient instance in ASP.NET Core, please check: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/http-requests?view=aspnetcore-3.1
I have an Vue.JS application, where I upload an image to a NetCore Controller.
I'm receiving the IFileForm in the following controller:
[HttpPost("UpdateContactPhoto")]
public async Task<string> UpdateContactPhoto(IFormFile file){ //Forward the original IFileForm to another NetCore API. }
At this point everything is working correctly. IFileForm arrives perfect.
My problem is that I need to forward this IFileForm to another API (independent of this) whose input is an IFileForm with HttpClient PutAsync, but not works.
Can someone help me?
Thanks for help.
You can use this example. Note that the argument name is the same as the item added to the form-data:
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:57985");
byte[] data;
using (var br = new BinaryReader(file.OpenReadStream()))
{
data = br.ReadBytes((int) file.OpenReadStream().Length);
}
ByteArrayContent bytes = new ByteArrayContent(data);
MultipartFormDataContent multiContent = new MultipartFormDataContent();
multiContent.Add(bytes, "file", file.FileName);
var result = client.PutAsync("api/v1/FileManager", multiContent).Result;
if (result.StatusCode == HttpStatusCode.OK)
{
//do some things
}
}
You can also use this code to get the file from the HttpContext :
IFormFile file = HttpContext.Request.Form.Files[0];
Replace "Target url here" with your destination URL:
HttpClient httpClient = new HttpClient();
var streamcontent = new StreamContent(file.OpenReadStream());
var response = await httpClient.PutAsync("target url here", streamcontent);
Reference:
HttpClient PutAsync
StreamContent class
IFormFile interface
I'm trying to make sense of the google indexing api but their documentation is horrible. I've gone through setting up the service account and downloading the json file along with the remaining prerequisites. The next step is to get an access token to authenticate.
I'm in a .net environment but they don't give an example for that. I did find some example of using a .net library to do it here, but after the following code I'm not sure what service would be created to then make the call to the indexing api. I don't see a google.apis.indexing library in the nuget package manager.
UserCredential credential;
using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
{
credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
new[] { "https://www.googleapis.com/auth/indexing" },
"user", CancellationToken.None, new FileDataStore("IndexingStore"));
}
In their example code it looks like just a simple json post. I tried that but of course it doesn't work because I'm not authenticated. I'm just not sure how to tie all of this together in a .net environment.
You're right, Google's documentation for this is either not there or is terrible. Even their own docs have broken or unfinished pages in them and in one of them you're pointed to a nuget package that doesn't exist. It is possible to get this to work though by cobbling together other Auth examples on SA and then following the Java indexing documentation.
First, you'll need to use nuget package manager to add the main api package and the auth package:
Google.Apis
Google.Apis.Auth
Then try the following:
using System;
using System.Configuration;
using System.IO;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Http;
using Newtonsoft.Json;
namespace MyProject.Common.GoogleForJobs
{
public class GoogleJobsClient
{
public async Task<HttpResponseMessage> AddOrUpdateJob(string jobUrl)
{
return await PostJobToGoogle(jobUrl, "URL_UPDATED");
}
public async Task<HttpResponseMessage> CloseJob(string jobUrl)
{
return await PostJobToGoogle(jobUrl, "URL_DELETED");
}
private static GoogleCredential GetGoogleCredential()
{
var path = ConfigurationManager.AppSettings["GoogleForJobsJsonFile"];
GoogleCredential credential;
using (var stream = new FileStream(path, FileMode.Open, FileAccess.Read))
{
credential = GoogleCredential.FromStream(stream)
.CreateScoped(new[] { "https://www.googleapis.com/auth/indexing" });
}
return credential;
}
private async Task<HttpResponseMessage> PostJobToGoogle(string jobUrl, string action)
{
var googleCredential = GetGoogleCredential();
var serviceAccountCredential = (ServiceAccountCredential) googleCredential.UnderlyingCredential;
const string googleApiUrl = "https://indexing.googleapis.com/v3/urlNotifications:publish";
var requestBody = new
{
url = jobUrl,
type = action
};
var httpClientHandler = new HttpClientHandler();
var configurableMessageHandler = new ConfigurableMessageHandler(httpClientHandler);
var configurableHttpClient = new ConfigurableHttpClient(configurableMessageHandler);
serviceAccountCredential.Initialize(configurableHttpClient);
HttpContent content = new StringContent(JsonConvert.SerializeObject(requestBody), Encoding.UTF8, "application/json");
var response = await configurableHttpClient.PostAsync(new Uri(googleApiUrl), content);
return response;
}
}
}
You can then just call it like this
var googleJobsClient = new GoogleJobsClient();
var result = await googleJobsClient.AddOrUpdateJob(url_of_vacancy);
Or if you're not inside an async method
var googleJobsClient = new GoogleJobsClient();
var result = googleJobsClient.AddOrUpdateJob(url_of_vacancy).Result;
Any samples on consuming rest service post method in windows 8 apps.Please let me know the possible links on that.
Try this
using System.IO;
using System.Net.Http;
using System.Text;
var objHttpClient = new HttpClient();
var formParameters = "<details><id>1</id><name>test</name></details>");
var objHttpRequestMessage = new HttpRequestMessage(HttpMethod.Post, "http://example.com/page");
objHttpRequestMessage.Content = new StreamContent(new MemoryStream(Encoding.UTF8.GetBytes(formParameters)));
objHttpRequestMessage.Content.Headers.Add("Content-Type", "text/xml");
var result = await objHttpClient.SendAsync(objHttpRequestMessage);
Also check HttpClient sample on MSDN
What about using a System.Net.Http.StringContent class?
using System.Net.Http;
using System.Text;
private async void Button_Click_1(object sender, RoutedEventArgs e)
{
var contentString = "<details><id>1</id><name>test</name></details>";
var httpClient = new HttpClient();
var httpRequestMessage = new HttpRequestMessage(
HttpMethod.Post,
"http://example.com/page");
httpRequestMessage.Content = new StringContent(
contentString,
Encoding.UTF8,
"text/xml");
var result = await httpClient.SendAsync(httpRequestMessage);
}
