我有一个apache cordova项目,我试图将表单数据从客户端发布到数据库。我可以看到我发送的json发送到我的API,然后将数据发送到DAL然后发送到数据库。该条目正确更新表,然后根据是否存在先前条目返回1或-1。然后将该值发送给客户端。我可以看到发回的确切响应,但我的ajax成功功能不会被激发。
的Ajax:
$("#submit").click(function () {
var info = {
Username: $("#username").val(),
Password: $("#password").val(),
Firstname: $("#firstname").val(),
Lastname: $("#lastname").val(),
Email: $("#email").val()
};
info = JSON.stringify(info);
event.preventDefault();
$.ajax({
type: "POST",
dataType: "json",
async: false,
url: "http://localhost:57207/api/User/RegisterUser",
data: info,
success: function(data) {
console.log(data);
},
error: function(input) {
console.log(JSON.stringify(input));
}
})
});
控制器:
[System.Web.Http.HttpPost]
public JObject RegisterUser(JObject obj)
{
RegisterUsers user = new RegisterUsers();
user = JsonConvert.DeserializeObject<RegisterUsers>(((JProperty)obj.First).Name);
var temp = DataAccessLayer.RegisterUser(user.Username, user.Password, user.Firstname, user.Lastname, user.Email, null, null);
JObject jobj = new JObject();
jobj.Add("output", temp.ToString());
return jobj;
}
我一直在使用fiddler检查我的回复和请求,这是原始数据:

{"output":"-1"}
我的错误函数是触发的函数,这是输出:
的console.log:
{"readyState":0,"status":0,"statusText":"NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://localhost:57207/api/User/RegisterUser'."}
更新
我能够将async设置为true,我的新错误信息就是:
{"readyState":0,"status":0,"statusText":"error"}
答案 0 :(得分:0)
请尝试返回IHttpActionResult
或IActionResult
,Ok()
以获得200回复。
public IActionResult RegisterUser(JObject obj)
{
RegisterUsers user = new RegisterUsers();
user = JsonConvert.DeserializeObject<RegisterUsers>(((JProperty)obj.First).Name);
var temp = DataAccessLayer.RegisterUser(user.Username, user.Password, user.Firstname, user.Lastname, user.Email, null, null);
JObject jobj = new JObject();
jobj.Add("output", temp.ToString());
return Ok(jobj);
}
如果它仍然失败,请尝试返回一个简单的字符串,如return Ok("Hello World!");
。如果它使用简单的字符串成功,那么对象的序列化可能会失败或者作为无效的JSON出现。
