RestSharp HTTP请求库

官方文档：https://restsharp.dev/intro.html#introduction

c# RestSharp(http请求)：https://blog.csdn.net/czjnoe/article/details/106482422

包引入

1. RestSharp
2. RestSharp.Serializers.NewtonsoftJson

如无必要不要使用AddJsonBody，因为某些接口会不识别

POST请求

参数为JSON

//定义
private RestClient client { get; set; }
//帮助类方法
public MoneyCardHelper()
{
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3
                                                   | SecurityProtocolType.Tls
                                                   | SecurityProtocolType.Tls11
                                                   | SecurityProtocolType.Tls12;
    client= new RestClient(baseApi);//定义根路径
    client.UseNewtonsoftJson();//使用NewtonsoftJson序列化，需要引入NewtonsoftJson包
    client.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)";
}

//方法中代码
string url = "Test/GetProjectList";
var request = new RestRequest(url, DataFormat.Json);
//添加POST参数
request.AddOrUpdateParameter("client_id", client_id);
request.AddOrUpdateParameter("client_secret", client_secret);
request.AddOrUpdateParameter("grant_type", grant_type);

var response = client.Post<GetProjectListDto>(request);
if (response.IsSuccessful){
    //请求成功
    var data = response.Data;//返回的结果
}else{
    response.ErrorMessage;//错误信息
}

获取结果if (response.IsSuccessful)时候后，response.Data就是设定的返回类型数据

Get请求

string url = "/test/all_info";
var request = new RestRequest(url, DataFormat.Json);
request.AddQueryParameter("statusCode", "0");
var response = client.Get<SyncInformationDto>(request);
if (response.IsSuccessful)
{
    //请求成功
    var data = response.Data;//返回的结果
}

token验证

//access_token为token文本，token_type为类型，例如：“Bearer”
client.Authenticator = new OAuth2AuthorizationRequestHeaderAuthenticator(
    access_token, token_type
);
