आप सामग्री-प्रकार का उपयोग करके प्रीफलाइट विकल्प अनुरोध को छोड़ सकते हैं: एप्लिकेशन/एक्स-www-form-urlencoded।
AngularJS:
var user = {
ID: 1,
Name: 'test'
};
$http({
url: "api.localhost/api/users/addUser",
method: "POST",
data: $.param(user),
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
withCredentials: true,
}).success(function (data, status, headers, config) {
console.log(data);
})
वेब एपीआई:
[HttpPost]
public string AddUser(User user)
{
// Do something
return user.Name + " added";
}
