415不支持的媒体类型

Question

我正在尝试使用Restkit在iOS应用程序中调用其他Web服务，但是我收到此错误： restkit.network:RKObjectRequestOperation.m:210 response.body = 415不支持的媒体类型

415不支持的媒体类型

我在我的代码中将此行设置为application / json：


$this->request->session()->write($name, $value);
$this->request->session()->read($name);

这是我在控制台中显示的请求

objectManager.requestSerializationMIMEType = RKMIMETypeJSON;

然后我发现问题可能是由{charset = utf-8引起的here引起的。我的问题是如何删除Restkit中的“charset = utf-8”

感谢@Wain评论，我通过创建请求并设置内容类型标题来解决问题：

 Private Sub Chart1_PostPaint(ByVal sender As Object, ByVal e As System.Windows.Forms.DataVisualization.Charting.ChartPaintEventArgs) Handles Chart1.PostPaint

        If TypeOf e.ChartElement Is Legend Then

            Dim c As Chart = CType(sender, Chart)
            Dim g As Graphics = e.ChartGraphics.Graphics

            'The legend
            Dim l As Legend = c.Legends(0)

            'Absolute dimensions of the legend (New legend will be based on this.. won't be exact.)
            Dim pos As RectangleF = e.ChartGraphics.GetAbsoluteRectangle(l.Position.ToRectangleF)

            'Absolute dimensions of one legend "cell"
            Dim itemHeight As Single = pos.Height / c.Series.Count
            Dim itemWidth As Single = pos.Width / 2

            'Padding between line and text (horizontal) and each item (vertical)
            Dim horizontalPadding As Single = 10
            Dim verticalPadding As Single = 1

            Dim legendFont As New Font("Arial", 10)

            'Draw a white box on top of the default legend to hide it
            g.FillRectangle(Brushes.White, pos)

            For i As Integer = 0 To c.Series.Count - 1

                Dim s As Series = c.Series(i)
                Dim p As New Pen(s.Color, CSng(Math.Min(s.BorderWidth, itemHeight))) 'Line no thicker than the item height.

                'Line
                Dim posY As Single = CSng(pos.Y + (verticalPadding * i + itemHeight * i + itemHeight / 2))
                Dim startPoint As PointF = New PointF(pos.X, posY)
                Dim endPoint As PointF = New PointF(CSng(pos.X + itemWidth), posY)
                g.DrawLine(p, startPoint, endPoint)

                'Text
                posY = CSng(pos.Y + verticalPadding * i + itemHeight * i)
                startPoint = New PointF(CSng(pos.X + itemWidth), posY)
                g.DrawString(s.Name, legendFont, Brushes.Black, startPoint.X + horizontalPadding, startPoint.Y)

            Next

        End If

    End Sub

我希望这有助于某人。这最近发生在我身上，我也缺少Content-Type。但是，您可以轻松地将其添加到RKObjectManager：

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:YOUR_BASE_URL]];
[manager setRequestSerializationMIMEType:RKMIMETypeJSON];
