【RestSharp】常用的几个请求方式

前言

经常用到，做个记录

代码

(1)Get-Request.Query取值

var url = "http://localhost:5000/api/RestSharp/TestGet";
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url);
RestRequest request = new() { Method = Method.Get };
foreach (var item in param)
{
    request.AddQueryParameter(item.Key, item.Value);
}
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);

 

(2)Get-FromQuery取值

var url = "http://localhost:5000/api/RestSharp/TestGetQuery";
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url);
RestRequest request = new() { Method = Method.Get };
foreach (var item in param)
{
    request.AddQueryParameter(item.Key, item.Value);
}
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);

 

(3)Post-Body-Json方式

var url = "http://localhost:5000/api/RestSharp/TestPostBodyJson";
var headers = new Dictionary<string, string>
{
    { "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36" },
};
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url);
RestRequest request = new() { Method = Method.Post };
request.AddOrUpdateHeaders(headers);
request.AddHeader("Content-Type", "application/json");
var body = JsonSerializer.Serialize(param);
request.AddStringBody(body, DataFormat.Json);
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);

 

(4)Post-Body-Text方式

var url = "http://localhost:5000/api/RestSharp/TestPostBodyText";
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url);
RestRequest request = new() { Method = Method.Post };
request.AddHeader("Content-Type", "text/plain");
var body = string.Join("&", param.Select(p => WebUtility.UrlEncode(p.Key) + "=" + WebUtility.UrlEncode(p.Value)));
request.AddParameter("text/plain", body, ParameterType.RequestBody);
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);

 

(5)Post-Form

var url = "http://localhost:5000/api/RestSharp/TestPostForm";
var headers = new Dictionary<string, string>
{
    { "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36" },
};
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url);
RestRequest request = new() { Method = Method.Post };
request.AddOrUpdateHeaders(headers);
foreach (var item in param)
    request.AddOrUpdateParameter(item.Key, item.Value);
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);

 

(6)Post-Form-禁止重定向

var url = "http://localhost:5000/api/RestSharp/Tokens";
var headers = new Dictionary<string, string>
{
    { "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36" },
    { "X-Forwarded-For", "123.321.123.321" },
};
var param = new Dictionary<string, string>
{
    { "User", "123456789@qq.com" },
    { "Pwd", "123$%^qwe..." },
};
var client = new RestClient(url, options => { options.FollowRedirects = false; });
RestRequest request = new() { Method = Method.Post };
request.AddOrUpdateHeaders(headers);
foreach (var item in param)
    request.AddOrUpdateParameter(item.Key, item.Value);
RestResponse response = await client.ExecuteAsync(request);
if (((int)response.StatusCode) != 303)
    Console.WriteLine((int)response.StatusCode);
string location = response.Headers?.Where(x => x.Name == "Location").FirstOrDefault()?.Value ?? "";
Console.WriteLine(location);
