使用JObject（VB.net）时，JObject.parse会抛出此错误：

Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 2, position 2.---- at Newtonsoft.Json.Linq.JObject.Load(JsonReader reader) at Newtonsoft.Json.Linq.JObject.Parse(String json)

但是当我将上面的字符串复制到在线Json观众中时，他们似乎都在解析它。

您的JSON不代表对象;它是一个数组（数组）。因此，您无法使用[peripheral respondToRequest:[requests objectAtIndex:0] withResult:CBATTErrorSuccess]; CBATTRequest *aRequest = requests[0]; NSData *aData = aRequest.value; NSString *string = [[NSString alloc] initWithData:aData encoding:NSUTF8StringEncoding]; [self logToDelegate:string];。相反，使用}，它可以处理数组，或使用-(void)peripheral:(CBPeripheral *)peripheral didWriteValueForCharacteristic:(CBCharacteristic *)characteristic error:(NSError *)error {，它可以处理数组或对象。



if(error) {
    [self callbackError:error];
    return;
}

[self logToDelegate:@"didWriteValueForCharacteristic"];


}       //didWriteValueForCharacteristic
