if(image != nil){
    mediaSize = String(image!.size.width) + "|" + String(image!.size.height)
}

结果应该是这样的"400|300"

我收到错误：No exact matches in call to initializer

image是UIImage，我在尝试将大小转换为字符串之前将其上传到服务器，并且它是有效的

关于此问题的其他问题没有帮助

根据此data文档，我正在尝试使用以下字段：

$fields = [
    'message' => [
        'token' => $deviceToken,
        'notification' => [
            'title' => $notifTitle,
            'body' => $notifDesc
        ],
        'data' => $data
    ]
]; 

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/v1/projects/bla/messages:send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );

$result = curl_exec($ch) . '<br><br>';
print($result);

其中$data包含以下内容：

array(11) {
  ["title"]=>
  string(21) "Antwort auf Kommentar"
  ["msg"]=>
  string(29) "Cornholio hat dir geantwortet"
  ["image"]=>
  string(12) "30321555.jpg"
  ["notifType"]=>
  string(5) "reply"
  ["channelID"]=>
  string(21) "channel_reply_comment"
  ["memeID"]=>
  int(20202)
  ["memeTitle"]=>
  string(10) "meme title"
  ["meme"]=>
  string(19) "TrlNO38.mp4"
  ["size"]=>
  string(7) "460|818"
  ["commentCount"]=>
  int(7)
  ["mentioned"]=>
  int(1)
}

我收到此错误：

{ “错误”：{ “代码”：400， “消息”：“'message.data[5].value'（TYPE_STRING）处的值无效，20202 \ n'message.data[9].value'（TYPE_STRING）处的值无效，7 \ n'message.data[10].value'（TYPE_STRING）处的值无效，1“，”status“：”INVALID_ARGUMENT“，”详细信息“：[{ “@type”：“type.googleapis.com/google.rpc.BadRequest”， “fieldViolations”：[{ “field”：“message.data[5].value”， “description”：“'message.data[5].value'（TYPE_STRING）处的值无效，20202” }，{ “field”：“message.data[9].value”， “description”：“'message.data[9].value'（TYPE_STRING）处的值无效， 7” }, { “field”：“message.data[10].value”， “description”：“‘message.data[10].value’ (TYPE_STRING) 处的值无效，1” } ] } ] } }

我能够使用旧的 API 发送这样的数据，但是如何使用当前的 API 来发送这样的数据呢？

我正在尝试弄清楚如何使用 PHP 向 Android 设备发送推送通知。

我已在多个网站上查找过它，这是我最后一次尝试：

function sendFCM($registrationIds, $notifTitle, $notifDesc, $notifChannel, $data) {

    $client = new Google_Client();
    $client->setAuthConfig('bla.json');
    $client->addScope('https://www.googleapis.com/auth/firebase.messaging');
    $client->refreshTokenWithAssertion();
    $token = $client->getAccessToken();
    $accessToken = $token['access_token'];

    $headers = array (
        'Authorization: Bearer ' . $accessToken,
        'Content-Type:application/json'
    );

    $notification = array
    (
        "title" => $notifTitle, 
        "body" => $notifDesc, 
        "icon" => "ic_logo_circle",
        "android_channel_id" => $notifChannel
    );

    $fields = array
    (
        'notification' => $notification, 
        'data' => $data, 
        'registration_ids' => $registrationIds
    );      

    $ch = curl_init();
    curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/v1/projects/projectname/messages:send' );
    curl_setopt( $ch,CURLOPT_POST, true );
    curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
    curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );

    $result = curl_exec($ch);
    print($result);

    curl_close($ch);
}

$notifData = array( 
    "title" => "this is the title",
    "msg" => "the desc",
    "image" => "whatever.jpg"
);

sendFCM($registrationIds, "Antwort auf Kommentar", "Cornholio hat dir geantwortet", "channel_reply_comment", $notifData);

$registrationIds包含多个 Android 设备令牌的数组

{ “错误”：{ “代码”：400，“消息”：“收到无效的 JSON 负载。未知名称“通知”：找不到字段。\ n收到无效的 JSON 负载。未知名称“数据”：找不到字段。\ n收到无效的 JSON 负载。未知名称“registration_ids”：找不到字段。“，”status“：“INVALID_ARGUMENT”，“详细信息”：[{“@type”：“type.googleapis.com/google.rpc.BadRequest”，“fieldViolations”：[{“描述”：“收到无效的 JSON 负载。未知名称“通知”：找不到字段。“}，{“描述”：“收到无效的 JSON 负载。未知名称“数据”：找不到字段。“}，{“描述”：“收到无效的 JSON 负载。未知名称“registration_ids”：找不到字段。“}]}]}

                let asset = tempFile.avAsset
                
                let vidWidth = await asset?.naturalSize()?.width
                let vidHeight = await asset?.naturalSize()?.height
                
                videoHeight = 160 * (vidHeight! / vidWidth!)
                videoURL = tempFile.url

            }
 
        }else{
            print("picking failed")
        }
    }
}

我明白了

如果“任务”上没有类型注释，则表达式类型不明确

如何修复？

在 MainView 中，我在 NaviationStack 下方有以下内容：

.navigationDestination(for: String.self){ selection in
    
    if(selection == "login"){
        Login()
    }else if(selection == "register"){
        CreateAccount()
    }
}

在子视图中，我有这个：

NavigationLink(value: "login"){
    Image(systemName: "person.circle.fill")
        .resizable()
        .aspectRatio(contentMode: .fit)
        .frame(height: profImgSize)
        .foregroundColor(Color(UIColor(named: "IconColor")!))
}

当我点击它时，我得到：

注意：链接在任何周围的 NavigationStack 中搜索目的地，然后在 NavigationSplitView 的同一列中搜索。
NavigationLink 显示“String”类型的值，但从链接位置看不到匹配的 navigationDestination 声明。链接无法激活。

当我创建一个最小的示例时，它就可以工作，而当我将所有代码发布到此处时，那就太多了。这里可能有什么问题？

struct Toolbar: View {
    
    let closeThisView: () -> Void?
    var toolbarTitle: String
    
    var body: some View {
        
        Text("bla")
    }
}


struct Toolbar_Previews: PreviewProvider {
    
    static var previews: some View {
        Toolbar(closeThisView: nil, toolbarTitle: "comments")
            .preferredColorScheme(.dark)
    }
}

nil既然我在预览中不需要它，我怎样才能传递它或任何函数？就像这就是我也尝试过的：

struct Toolbar_Previews: PreviewProvider {
    
    @Environment(\.dismiss) var dismiss
    func closeThisView(){

        DispatchQueue.main.async {
            self.dismiss()
        }
    }
    
    static var previews: some View {
        Toolbar(closeThisView: closeThisView, toolbarTitle: "comments")
            .preferredColorScheme(.dark)
    }
}

我正在尝试从购买中获取productId：

private fun queryPurchases(purchases: List<Purchase>){

    for (purchase in purchases) {

        Log.d("pikaboo", purchase.toString())

        when (purchase.purchaseState) {
            Purchase.PurchaseState.PURCHASED -> {

                val purchaseTime = (purchase.purchaseTime / 1000).toInt()

                when (purchase.productId) {
                    "no_ads_in_app_month" -> {

                    }
                    "no_ads_in_app_3_months" -> {

                    }
                }
            }
        }
    }
}

这是日志：

Purchase. Json: {"orderId":"GPA.333.333.333","packageName":"de.bla.foo","productId":"no_ads_in_app_3_months","purchaseTime":1694810217354,"purchaseState":0,"purchaseToken":"xxxxxxxxxxxx","quantity":1,"acknowledged":true}

在是productId_purchase.productIdUnresolved reference

其他一切都像purchase.purchaseTime purchase.purchaseState purchase.packageName作品一样。

为什么不呢purchase.productId？这是一个错误吗？怎么解决这个问题呢？
