Question

我正在＆＃34; \ n＆＃34;在websocket / SignalR响应中，我似乎无法弄清楚原因。我已经尝试更改响应对象的数据类型，将其解析为好像它是JSON，但仍然无法摆脱＆＃34; \ n＆＃34;。

如何删除此＆＃34; \ n＆＃34;并像处理任何其他JSON对象/响应那样处理它？</ p>

参考代码：

-(void)SignalR{

    WebServices *services = [[WebServices alloc] init];

    SRHubConnection *hubConnection = [SRHubConnection connectionWithURLString:@"xxx"];

    SRHubProxy *proxy = [hubConnection createHubProxy:@"xxx"];

    [services callGetSRAlertGroupNames:^(NSMutableArray *alertGroupNameArray){
        NSLog(@"SR ALERT GROUP NAMES: %@", alertGroupNameArray);

        [services callGetSRNotificationGroupNames:^(NSMutableArray *notificationGroupNameArray) {
            NSLog(@"SR NOTIFICATION GROUP NAMES: %@", notificationGroupNameArray);

            NSArray *combinedArray=[alertGroupNameArray arrayByAddingObjectsFromArray:notificationGroupNameArray];

            // Register for connection lifecycle events
            [hubConnection setStarted:^{

                NSLog(@"Connection Started");

                for (NSString *groupName in combinedArray ){
                    [proxy invoke:@"Subscribe" withArgs:@[groupName] completionHandler:nil];
                }

            }];
            [hubConnection setReceived:^(NSString *data) {

                NSLog(@"CONNECTION RECIEVED - %@",data);

            }];
            [hubConnection setConnectionSlow:^{
                NSLog(@"Connection Slow");
            }];
            [hubConnection setReconnecting:^{
                NSLog(@"Connection Reconnecting");
            }];
            [hubConnection setReconnected:^{
                NSLog(@"Connection Reconnected");
            }];
            [hubConnection setClosed:^{
                NSLog(@"Connection Closed");
            }];
            [hubConnection setError:^(NSError *error) {
                NSLog(@"Connection Error %@",error);
            }];

            [hubConnection start];

        }];
    }];
}

退出回复示例：

CONNECTION RECIEVED - {
    A =     (
        "{
\n  \"NotificationType\": 1,
\n  \"TelemetryDetails\": {
\n    \"serialNumber\": \"xxx\",

简单。

您可以使用：

data = [data stringByReplacingOccurrencesOfString:@"\n" withString:@""];

但这个伎俩是＆＃34;脏＆＃34;因为问题显然来自你的网络服务，我想。

修改

你在哪里取代事件？

你能告诉我这个日志是什么吗？

[hubConnection setReceived:^(NSString *data) { NSLog(@"CONNECTION RECIEVED - %@",data); NSString *newString = [data stringByReplacingOccurrencesOfString:@"\n" withString:@""]; NSLog(@"NEW STRING - %@", newString); }];

编辑2：

好的，您可以尝试在完成处理程序之外添加此变量。

__block NSString *newString;

或者你也可以试试这个

[hubConnection setReceived:^(NSString *data) { NSLog(@"CONNECTION RECIEVED - %@",data); [self replaceOccurrences: data]; }]; - (void)replaceOccurrences:(NSString *)data { NSString *newString = [data stringByReplacingOccurrencesOfString:@"\n" withString:@""]; NSLog("New String = %@", newString); }

但是你真的应该检查你的后端，这种反应的格式不合适。

获得＆＃34; \ n＆＃34;在websocket / SignalR响应？
