如何使用webmethod将HTML代码更改为C＃ [英] How can I change HTML code to C# using webmethod

问题描述

< form method =postaction =http://test.co.in/api/bus/search_trip.php> 
< textarea name =request> 
 {uid：XXXX，pin：XXXXX，source_id：1270，destination_id：323，日期：25-04-2017} 
< / textarea> 
 
<！ - < input type =textname =valuevalue =json>  - > 
< input type =submitname =submitvalue =submit> 
< / form> 

我尝试了什么：



当我使用ASP.NET C＃向给定网址发出请求时，它只返回无效请求格式

解决方案

< pre lang =c＃> string json = { \uid \：\xxxx \，\pin \：\xxxx \，\source_id \：\1270 \，\ destination_id \：\323 \，\date \：\05-05-2017 \};
var httpContent = new StringContent（json，Encoding.UTF8， application / json）;
使用（ var httpClient = new HttpClient（））
{
// 此处出错
var httpResponse = await httpClient.PostAsync（ http://pudhukadai.co.in/api/bus/search_trip.php，httpContent）;
if （httpResponse.Content！= null ）
{
// 此处出错
var responseContent = await httpResponse.Content.ReadAsStringAsync（）;
}
}

你可能想看看Newtonsoft.Json来处理创建Json字符串。

<form method="post" action="http://test.co.in/api/bus/search_trip.php">
<textarea name="request">
 { "uid" : "XXXX", "pin":"XXXXX", "source_id":"1270", "destination_id":"323", "date":"25-04-2017"  }
</textarea>
 
<!--<input type="text" name="value" value="json">-->
<input type="submit" name="submit" value="submit">
</form>

What I have tried:

when i m giving the request to the given url using ASP.NET C# it returns only "Invalid Request Format"

解决方案

string json = "{\"uid\": \"xxxx\",\"pin\": \"xxxx\",\"source_id\": \"1270\",\"destination_id\": \"323\",\"date\": \"05-05-2017\"}";
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
    // Error here
    var httpResponse = await httpClient.PostAsync("http://pudhukadai.co.in/api/bus/search_trip.php", httpContent);
    if (httpResponse.Content != null)
    {
        // Error Here
        var responseContent = await httpResponse.Content.ReadAsStringAsync();
    }
}

and you may want to look at Newtonsoft.Json to handle creating the Json string.
