RestSharp JSON POST 请求遇到错误请求

Question

我正在使用 RestSharp 发出一个包含 JSON 正文的 POST 请求。但是我收到一个 Bad request 错误。

因为我的 JSON 中有 [] 和 "" 我决定使用 Newtonsoft.Json 。在使用它之前，我什至看不到正在形成的 JSON 请求。

我愿意尝试 MS httpwebrequest 作为替代方案。

restClient = new RestClient();

restRequest = new RestRequest(ApiUrl, Method.POST, DataFormat.Json);

var myObject = "{ \"target\" : \"[5,5]\", \"lastseen\" : \"1555459984\" }";

var json = JsonConvert.SerializeObject(myObject);
restRequest.AddParameter("application/json", ParameterType.RequestBody);

restRequest.AddJsonBody(json);

请注意，我正在尝试将 JSON curl 转换为 C#。请看下面：

curl -H 'Content-Type: application/json' -X POST -d '{ "target" : [5, 5], "lastseen" : "1555459984", "previousTargets" : [ [1, 0], [2, 2], [2, 3] ] }' http://santized/santized/santized

Answer 1

您似乎过度序列化要发送的数据。

考虑创建一个对象，然后将其传递给 AddJsonBody。

//...

restClient = new RestClient();

restRequest = new RestRequest(ApiUrl, Method.POST, DataFormat.Json);

var myObject = new { 
    target = new []{ 5, 5 }, 
    lastseen = "1555459984",
    previousTargets = new []{
        new [] { 1, 0 }, 
        new [] { 2, 2 }, 
        new [] { 2, 3 } 
    }
};

restRequest.AddJsonBody(myObject); //this will serialize the object and set header

//...

AddJsonBody 将内容类型设置为 application/json 并将对象序列化为 JSON 字符串。

为什么不只是这个？

restClient = new RestClient();

restRequest = new RestRequest(ApiUrl, Method.POST, DataFormat.Json);

var myObject = "{ \"target\" : \"[5,5]\", \"lastseen\" : \"1555459984\" }";

restRequest.AddParameter("application/json", ParameterType.RequestBody);

restRequest.AddJsonBody(json);

删除了序列化 json 字符串的行。

您还可以使用：

public class RootObject
{
    public string target { get; set; }
    public string lastseen { get; set; }
}

restClient = new RestClient();

restRequest = new RestRequest(ApiUrl, Method.POST, DataFormat.Json);

RootObject myObject = new RootObject();
myObject.target = "[5,5]";
myObject.lastseen = "1555459984";
var json = JsonConvert.SerializeObject(myObject);

restRequest.AddParameter("application/json", ParameterType.RequestBody);

restRequest.AddJsonBody(json);

你可以做这个例子：

  public static IRestRequest PostInformationAndPassToken(JsonObject tokenString, string path, string whatistobePosted)
    {
        IRestRequest request = new RestRequest(path, Method.POST);
        request.AddHeader("Authorization", $"Bearer {tokenString["Token"]}");
        request.AddHeader("cache-control", "no-cache");
        request.AddHeader("Content-Type", "application/json");
        request.AddParameter(whatistobePosted, ParameterType.RequestBody); 
        return request;
    }
