发布JSON整数数组

Question

我正在尝试将一些JSON数据发布到API以添加帐户。 说明指定ids参数可以是：字符串（逗号分隔）或整数数组

我意识到我可以将逗号分隔的id放入查询字符串中但是我想将这些数据作为JSON发布，因为我可能有很多这些。

以下是我的尝试：

public static HttpClient GetHttpClient()
{
    var property = Properties.Settings.Default;

    HttpClient client = new HttpClient();
    client.BaseAddress = new Uri(property.apiUrl);
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Add("X-OrgSync-API-Key", property.apiKey);
    return client;
}

HttpClient client = Api.GetHttpClient();
string json = "{\"ids\":[10545801,10731939]}";
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync($"{client.BaseAddress}/classifications/{classification.id}/accounts/add", httpContent);

它“成功”运行，但实际上没有在API服务器端设置。

关于我在这里做错了什么的任何想法？ 此外，任何类型的工具/技术等，特别是在Visual Studio中，可以让我更好地了解请求/响应流量？

我知道这是可能的，因为当我使用像Postman这样的工具时它正确地添加了帐户ID：

关于工具/技术，您可以使用Fiddler动态捕获请求和响应，以检查Raw请求是否正确。

如果您之前没有使用它，请查看here以获取有关如何捕获请求和响应的说明。

Answer 2

尝试使用以下代码

using (var client= new HttpClient()) {
string json = "{\"ids\":[10545801,10731939]}";
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync($"{client.BaseAddress}/classifications/{classification.id}/accounts/add", httpContent);

 // If the response contains content we want to read it!
    if (response .Content != null) {
        var responseContent = await response.Content.ReadAsStringAsync();
//you will get your response in responseContent 
}

我能够通过将StringContent编码类型从Encoding.UTF8更改为null或Encoding.Default来获得json字符串方法。

string json = "{\"ids\":[10545801,10731939]}";
var httpContent = new StringContent(json, Encoding.Default, "application/json");
var response = await client.PostAsync($"{client.BaseAddress}/classifications/{classification.id}/accounts/add", httpContent);

我还想出了一种方法，可以使用包含int数组的id的对象和Encoding.UTF8;

HttpClient client = Api.GetHttpClient();
var postData = new PostData {ids = new[] {10545801,10731939}};
var json = JsonConvert.SerializeObject(postData);
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync($"{client.BaseAddress}/classifications/{classification.id}/accounts/add", httpContent);

如果您不想仅仅为了存储帖子数据而创建一个类，您可以使用匿名类型：

var postData = new { ids = new[] {10545801,10731939}};
var json = JsonConvert.SerializeObject(postData);
var httpContent = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync($"{client.BaseAddress}/classifications/{classification.id}/accounts/add", httpContent);
