使用c＃从REST API获取JSON内容（有工作的javascript示例） [英] Get JSON content from REST API using c# (have working javascript example)

问题描述

Hello Everybody，

在过去的几个小时里，我一直在尝试从需要用户名和密码的其他https api接收一个简单的JSON对象。

该公司在Javasccript中提供了一个如何获取信息的工作示例。我不知道javascript，只有c＃，但我似乎无法使它工作。可能是因为我不熟悉wen http请求等。

这是正常工作的JS代码：

 function signin（）{
 username = $（'＃inputUsername'）。val（）; 
 pass = $（'＃inputPassword'）。val（）; 
 if（pass.length> 0&& username.length> 0）{
 //构建帖子请求
 $ .post（source +" / login"，{ username：username，password：pass}，function（data，textStatus，jqxhr）{
 $（" header div h4＃header_username"）。html（username）; 
 token = data.auth; 
 $（'＃main-content'）。show（）
 $（'＃form-signin'）。hide（）
 populateVehicles（）; 
}）; 
} 
} 

有人可以帮我转换成c＃吗？我一直在尝试使用HttpClient或HttpRequest，每次收到401 Unauthorized Error或Bad Request Error。

提前致谢。

找到解决方案。发送凭据只能像这样工作。希望它有所帮助。

 var data = new NameValueCollection（）; 
 data [" username"] =" USERNAME" ;; 
 data [" password"] =" PASSWORD" ;; 
 
 var response = wb.UploadValues（" URL"，" POST"，data）; 

解决方案

到目前为止你有什么？您需要（我猜）基本的Web凭据，例如

 using（WebClient client = new WebClient（））
 {
 client.Credentials = new NetworkCredential（" username"，" password"）; 
 // .. 
} 

Hello Everybody,

For the last few hours I've been trying to receive a simple JSON object from a rest https api that requires username and password.

The company provided a working example in Javasccript how to get the info. I don't know javascript, only c#, but I can't seem to make it work. Probably because I'm not familiar with wen http requests etc.

This is the working JS code:

function signin(){
            username = $('#inputUsername').val();
            pass = $('#inputPassword').val();
            if(pass.length > 0 && username.length > 0){
                //Build post request
                $.post( source+"/login", {username: username, password:pass}, function( data, textStatus, jqxhr ) {
                    $("header div h4#header_username").html(username);
                    token = data.auth;
                    $('#main-content').show()
                    $('#form-signin').hide()
                    populateVehicles();
                });
            }
        }

Could anyone help me convert it to c#? I've been trying to use HttpClient or HttpRequest and each time I receive a 401 Unauthorized Error or Bad Request Error.

Thanks in advance.

Found the solution. Sending the credentials worked only like this. Hope it helps.

                var data = new NameValueCollection();
                data["username"] = "USERNAME";
                data["password"] = "PASSWORD";

                var response = wb.UploadValues("URL", "POST", data);

解决方案

What have you so far? You need (I guess) basic web credentials, something like

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("username", "password");
    //..
}
