Question

我正在尝试发送PUT请求来更新一些数据。在检查员的Fiddler＆gt;文本查看数据显示如下：

"{\"site\":[{\"technologyId\":1,\"isActive\":1},{\"technologyId\":2,\"isActive\":1},{\"technologyId\":3,\"isActive\":1},{\"technologyId\":4,\"isActive\":1}]}"

如果我在调试时在TextViewer中打开jsonData，则会显示以下内容：

{"site":[{"technologyId":1,"isActive":1},{"technologyId":2,"isActive":1},{"technologyId":3,"isActive":1},{"technologyId":4,"isActive":1}]}

我认为这是在PutAsJsonAsync中传递jsonData时传递给服务器的内容。

在fiddler中，响应以500内部服务器错误的形式返回，如果我单击TextView，则会显示{"error":"Error: invalid json"}。据我所知，\是C＃中"的转义字符，不应传递。我不知道如何解决这个问题

static void Main()
{
    RunAsync().Wait();
}

static async Task RunAsync()
{
    using (var client = new HttpClient())
    {
        Uri siteTechUpdateUrl = new Uri("http://xyz/api/1234");
        // HTTP PUT
        // Update site# 16839 Technologies

        var collection = new List<SiteTechnology>();
        collection.Add(new SiteTechnology() { technologyId = 1, isActive = 1 });
        collection.Add(new SiteTechnology() { technologyId = 2, isActive = 1 });
        collection.Add(new SiteTechnology() { technologyId = 3, isActive = 1 });
        collection.Add(new SiteTechnology() { technologyId = 4, isActive = 1 });
        dynamic siteTechs= new
        {
            site = collection
        };
        string jsonData = JsonConvert.SerializeObject(siteTechs);  
        // jsonData value "{\"site\":[{\"technologyId\":1,\"isActive\":1},{\"technologyId\":2,\"isActive\":1},{\"technologyId\":3,\"isActive\":1},{\"technologyId\":4,\"isActive\":1}]}"               
        HttpResponseMessage response2 = await client.PutAsJsonAsync(siteTechUpdateUrl, jsonData);

        if (response2.IsSuccessStatusCode)
        {
            Console.ReadLine();
        }
    }
}

class SiteTechnology
{
    public int technologyId;
    public int isActive;
}

Answer 1

您将其序列化为字符串，然后将字符串作为JSON发送。

而不是：

client.PutAsJsonAsync(siteTechUpdateUrl, jsonData);

尝试：

client.PutAsJsonAsync(siteTechUpdateUrl, siteTechs);

\转义字符在PutAsJsonAsync中作为json传递
