contentType属性应用程序/ xml上的错误有效但application / json没有

Question

这是我的第一个问题。我一直在搜索Stack Overflow和其他Web资源，但我无法找到FullCalendar正确接受jQuery数据属性所需的可靠答案。

我的意思是我有一个Web服务，它接受一个字符串作为其必需参数。我打电话给 * owner_email * 。

Web服务将获取该参数并返回由FullCalendar呈现的UserAssignments数组。

我遇到了将* owner_email *从jQuery / FullCalendar实际传递到ASP.NET Web服务的问题。

当我将contentType更改为'application / xml'或将其注释掉时，它会返回一个空的XML文档（我现在想要它）但是当我将其更改回'application / json'时，json中会出现错误格式。任何帮助表示赞赏。另外，我想知道将事件放在F​​ullCalendar上需要什么。

这是我到目前为止所做的代码：
JavaScript的：

$("#calendar").fullCalendar({ dayClick: function () { alert('a day was clicked!'); }, eventSources: [

// your event source { url: "WebService.asmx/displayUserAssignments", type: 'POST', data: { owner_email: 'test' }, processData: true, dataType: "json", contentType: 'application/json', color: 'yellow', // a non-ajax option textColor: 'black' // a non-ajax option } // any other sources... ]

ASP.NET代码段：

[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public UserAssignments[] displayUserAssignments(string owner_email) { int totalAssignments = 0; int current_index = 0; UserAssignments[] compiled_user_assignments; OracleConnection openedConnection = new OracleConnection(WebConfigurationManager.ConnectionStrings["BehemothConn"].ConnectionString); openedConnection.Open(); OracleCommand query = new OracleCommand("SELECT * FROM personal_assignments_view where owner_email = :input_email", openedConnection); OracleCommand numberOfRows = new OracleCommand("select count(*) from personal_assignments_view where owner_email = :input_email", openedConnection);

query.Parameters.Add(":input_email", OracleType.VarChar).Value = owner_email; numberOfRows.Parameters.Add(":input_email", OracleType.VarChar).Value = owner_email;

OracleDataReader returned_result = numberOfRows.ExecuteReader(); returned_result.Read(); totalAssignments = returned_result.GetInt32(0);

compiled_user_assignments = new UserAssignments[totalAssignments]; returned_result = query.ExecuteReader();

while (returned_result.Read()) { compiled_user_assignments[current_index] = new UserAssignments(); compiled_user_assignments[current_index].assignment_id = returned_result.GetInt32(0); compiled_user_assignments[current_index].owner_email = returned_result.GetString(1); compiled_user_assignments[current_index].assignment_name = returned_result.GetString(2); compiled_user_assignments[current_index].assignment_date = returned_result.GetOracleDateTime(3).Value.ToString("R"); compiled_user_assignments[current_index].assignment_description = returned_result.GetString(4); compiled_user_assignments[current_index].event_id = returned_result.GetInt32(5); compiled_user_assignments[current_index].week_day = returned_result.GetString(6); compiled_user_assignments[current_index].is_deleted = returned_result.GetString(7); compiled_user_assignments[current_index].start_time = returned_result.GetInt32(8); compiled_user_assignments[current_index].end_time = returned_result.GetInt32(9); compiled_user_assignments[current_index].is_completed = returned_result.GetString(10); compiled_user_assignments[current_index].pan_note_id = returned_result.GetInt32(11); compiled_user_assignments[current_index].pan_assign_id = returned_result.GetInt32(12); compiled_user_assignments[current_index].assignment_note = returned_result.GetString(13); current_index++; }

openedConnection.Close(); openedConnection.Dispose(); return compiled_user_assignments; }

UserAssignments类：

public class UserAssignments { public int assignment_id; public string owner_email; public string assignment_name; public string assignment_date; public string assignment_description; public int event_id; public string week_day; public string is_deleted; public int start_time; public int end_time; public string is_completed; public int pan_note_id; public int pan_assign_id; public string assignment_note;

public UserAssignments() { assignment_id = -1; owner_email = ""; assignment_name = ""; assignment_date = ""; assignment_description = ""; event_id = -1; week_day = ""; is_deleted = ""; start_time = -1; end_time = -1; is_completed = ""; pan_note_id = -1; pan_assign_id = -1; assignment_note = ""; } }

jQuery错误：

我想您使用的是＆gt; = .NET 3.5

问题是：您的数据格式不正确。尝试使用JSON.stringify（）并生成JSON数据，如果您不想要JSON2.js，请尝试手动以适当的JSON格式创建数据。

如果将数组作为JSON返回，Fullcalendar可以很好地解决问题。

您将获得与start参数相同的错误消息。问题在于fullcalendar尝试将start和end参数附加到您的数据，但start和end不是JSON格式。因此，您必须转到fullcalendar.js并在函数_fetchEventSource（source，callback）中编辑以下内容。

 $.ajax($.extend({}, ajaxDefaults, source, {
                        data: JSON.stringify(data),
                        success: function (events) {
                            events = events.d;
                           ............................

在您的网络服务中： -

PS：不要尝试将webservice中的列表转换为任何格式。只需返回List对象。在成功事件中，您必须从名为“d”的“密钥”中获取JSON对象，因为在新版本中，它将对象封装在名为“d”的密钥中以进行ajax调用。所以使用该密钥访问它。

您的网络服务签名（示例）：

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
  public List<Object> functionName(argumentList)
  { return ObjectList;}

如果您使用XML返回，那么您必须在javascript和call中以适当的格式创建event []对象 - ＆gt;要显示fullcalendar的回调（事件）。
