httpclient

问题 I am trying to upload file to an url, and have received instead of regular JSON string response, only ResponseEntityProxy{[Content-Type: application/json;charset=UTF-8,Chunked: true]} . As I understood, there is JSON string as a response in there and I need to extract it somehow. Here is my code what I have tried so far to do (this is in the method where I am uploading file to an url): public String uploadDocument() { String responseMsg="empty"; try(CloseableHttpClient client = HttpClients

问题 I'm kind of new to RESTful consumption using http client in .net and i'm having trouble understanding how to use the retry-after header when polling an external API.

问题 I really am not sure what is happening. I'm using an HttpClient to post XML content to a remote server using the PostAsync method like this: using var content = new StringContent(payload, Encoding.UTF8, "application/xml"); using var response = await _httpClient.PostAsync(string.Empty, content); ... where payload is a string, and relative uri is empty because I just need to call base uri of httpclient. I can perform same request in Postman and it works fine. The issue is, for some reason

问题 I am new to Angular and RxJS operators. I need help in one of the scenario in which I upload multiple documents at once in the backend (Rest API).

问题 When writing a WPF application, the PasswordBox stores the entered password as a SecureString . This totally makes sense. However, I want to send the password via a HTTP API, and the HttpClient PostAsync seems to accept strings for form-encoded data. I am aware that other people have asked related questions, most notably Is SecureString ever practical in a C# application?, but I have not found a satisfactory method to send this SecureString to the Http endpoint, without first converting it to

问题 Good afternoon! I use Azure Maps API using HttpClient. How can I enable support of TLS 1.2? As I know in Framework 4.6+ it is supported. And I should not do anything work for this? 回答1: In general you do not need to specify any configuration in your application to enable adoption of the latest TLS protocol. Best practices and scenarios are outlined on docs.microsoft.com for earlier than .Net 4.7. At high level, you should make audit to make sure your application doesn't take any hard

问题 I have the content I want to POST available in a string variable. I want to use: import { HttpClient } from '@angular/common/http' ... in order to accomplish the same effect as: curl -F "image=@blob.bin" someurl.com ... where the contents of my string variable would be what might be in a local file called `blob.bin.

问题 I'm using HTTPClient in .netcore but I'm facing an issue when I add a custom accept header. var client = new HttpClient { Timeout = new TimeSpan(0, 5, 0)}; client.DefaultRequestHeaders.Clear(); client.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1"); But after this, what I see is that a space has been automaticaly added, resulting in " application/vnd.pagseguro.com.br.v3+json; charset=ISO-8859-1 ".
