我正在尝试使用[此API]（https://docs.microsoft.com/en-us/rest/api/vsts/release/approvals/update）。下面是我的代码，但我收到400个错误的请求。
MyQObject obj;
obj.db = 11.1;
QVariant value = QVariant::fromValue(obj);
std::string t = value.typeName();
int id = QMetaType::type(t.c_str());
void* v = QMetaType::create(id, value.constData());
obj_ptr = static_cast<QObject*>(v);
QJsonValue json = ToJson(obj_ptr); //json contains db = 11.1

由于您只提供部分代码，因此我在下面发布了我的代码（可以成功更新批准）以供您参考：
@import "modules/some_css";
引用博客Using ReleaseManagement REST API’s。
注意：您只能更新状态为public static async void ApproveRelease()
{
try
{
var username = "alternate auth or PAT";
var password = "password";
string accountName = "https://account.visualstudio.com";
string projectName = "projectname";
int approvalid = id;
var approveReleaseUri = "https://accountname.vsrm.visualstudio.com/projectname/_apis/release/approvals/approvlID?api-version=4.1-preview.3";
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", username, password))));
var method = new HttpMethod("PATCH");
string approvveReleaseMetaData = "{\"status\":\"approved\", \"comments\":\"Good to go\"}";
var request = new HttpRequestMessage(method, string.Format(approveReleaseUri, accountName, projectName, approvalid, apiVersion))
{
Content = new StringContent(approvveReleaseMetaData, Encoding.UTF8, "application/json")
};
using (HttpResponseMessage response = client.SendAsync(request).Result)
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
的发布审批。如果您尝试更新批准状态为pending或approved的版本审批，您还会收到rejected响应。
