Question

我使用ionic2：我的应用程序使用Web服务API并且它在浏览器中正常工作，因为我在浏览器中启用了Private Sub CommandButton1_Click() '//this macro checks whether two sheet's data is correspondent. Dim i1 As Long Dim i2 As Long Dim text1 As String Dim text2 As String text1 = UserForm2.TextBox1.Value text2 = UserForm2.TextBox2.Value Dim testSheet1 As Worksheet Dim testSheet2 As Worksheet testSheet1 = ThisWorkbook.Worksheets(text1) testValue2 = ThisWorkbook.Worksheets(text2) For i2 = 1 To 31 For i1 = 1 To 27 If testSheet1.Cells(i1, i2).Value <> testSheet2.Cells(i1, i2).Value Then MsgBox "Value of " & i1 & "rows " & i2 & "column : " & Chr(13) & Chr(10) _ & text1 & " sheets : " & testSheet1.Cells(i1, i2).Value & Chr(13) & Chr(10) _ & text2 & " sheets : : " & testSheet2.Cells(i1, i2).Value End If Next i1 Next i2 MsgBox "End" End Sub但是我将它运行到ios模拟器我有这样的错误：{{1在我所有的api服务方法中，我都附加了这样的标题：

cors origin plugin

我尝试发送这样的标题：

Response with status: 0 for URL: null

我设置的

addPost(token, image, description) {
    var headers = new Headers();
    headers.append('Content-Type', 'applocation/json');
    headers.append('Access-Control-Allow-Origin', '*');

    let postObject = {
        "token": token,
        "image": image,
        "description": description,
    }
    console.log("from service "+ postObject.description);
    console.log("from service "+ postObject.image);
    return this.http.post(this.addPostUrl,postObject,{headers:headers})
    .map((response: Response) => response.json())
}

文件中的

：

let headers = new Headers( {
        'Access-Control-Allow-Origin' : '*',
        'Access-Control-Allow-Methods' : 'POST, GET, OPTIONS, PUT',
        'Content-Type': 'application/json; charset=UTF-8',
        'Accept': 'application/json',
        'Access-Control-Allow-Headers': 'Origin, X-Requested-With, Content-Type, Accept'
    });

但运行到ios模拟器时出现同样的错误，我该怎么做才能解决这个问题？

我在Windows 10上发现了我的问题并希望分享。我希望它能提供一些见解。 Windows 8.1 / 10上的UWP拒绝环回。它必须设置为免除。
