我想使用webclient而不是httpclient。

本文介绍了我想使用webclient而不是httpclient。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

以下代码工作正常，我只想使用没有异步的webclient。 或者我们可以从下面的方法中删除asnc并使它像常规方法一样。 //使用控制台应用程序从program.cs调用方法

static void Main（string [] args） { AsyncCallbackUrlPost （f0c9b87f41fd0b7824ffdadeccefefefdd3c39929dbceca61b3450d497981a5eeeec354713d61263a71e3a953beebf62b12d6d9819ebb0593e7947766e8bef03，http：// localhost：54262 / api / Payload）; Console.ReadLine（）; }

//这个方法我想用webclient替换

public static async Task AsyncCallbackUrlPost（string loanBeamMessageHash，string callbackURL） { HttpResponseMessage httpResponseMessage = null; 尝试 { Uri objUri = new Uri（callbackURL）; //创建一个Http客户端并设置我们想要的头文件 HttpClient httpClient = new HttpClient（）; httpClient.DefaultRequestHeaders.Accept.Add（new MediaTypeWithQualityHeaderValue（application / json））; //将其添加到Response Header并将其命名为LoanBeam_MessageHash httpClient.DefaultRequestHeaders.Add（LoanBeam_MessageHash，loanBeamMessageHash）; httpClient.DefaultRequestHeaders.Host = objUri.Host; StringContent theContent = new StringContent（loanBeamMessageHash，System.Text.Encoding.UTF8，application / json）; //发布数据 httpResponseMessage = await httpClient.PostAsync（objUri，theContent）; //句柄状态代码200 if（httpResponseMessage.StatusCode == System.Net.HttpStatusCode.OK） { Console.WriteLine（HTTP状态成功：+ httpResponseMessage.ReasonPhrase）; 返回; } 其他 { return; } } catch（exception ex） { Console.WriteLine（HTTP status error：+ httpResponseMessage.ReasonPhrase）; } }

解决方案

WebClient文档中有一个示例。 WebClient类（System.Net） [ ^

This below code is working fine, i just wanted to do it using webclient without async. Or can we remove anyways asnc from below method and make it like regular method. // Calling method from program.cs using console application

static void Main(string[] args) { AsyncCallbackUrlPost("f0c9b87f41fd0b7824ffdadeccefefefdd3c39929dbceca61b3450d497981a5eeeec354713d61263a71e3a953beebf62b12d6d9819ebb0593e7947766e8bef03", "localhost:54262/api/Payload"); Console.ReadLine(); }

// This method i want to replace with webclient

public static async Task AsyncCallbackUrlPost(string loanBeamMessageHash, string callbackURL) { HttpResponseMessage httpResponseMessage = null; try { Uri objUri = new Uri(callbackURL); //Create an Http client and set the headers we want HttpClient httpClient = new HttpClient(); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); //Add it to Response Header and call it "LoanBeam_MessageHash" httpClient.DefaultRequestHeaders.Add("LoanBeam_MessageHash", loanBeamMessageHash); httpClient.DefaultRequestHeaders.Host = objUri.Host; StringContent theContent = new StringContent(loanBeamMessageHash, System.Text.Encoding.UTF8, "application/json"); //Post the data httpResponseMessage = await httpClient.PostAsync(objUri, theContent); //handle status code 200 if (httpResponseMessage.StatusCode == System.Net.HttpStatusCode.OK) { Console.WriteLine("HTTP status success: " + httpResponseMessage.ReasonPhrase); return; } else { return; } } catch (Exception ex) { Console.WriteLine("HTTP status error: " + httpResponseMessage.ReasonPhrase); } }

There is an example on the WebClient documentation. WebClient Class (System.Net)[^]
