在下面的云功能中获取错误。indexOf在通过云解析时出现未定义错误
NSMutableDictionary * params = [NSMutableDictionary new];
params[@"user"] = _sender_ID;
params[@"recipientId"] = _owner_ID;
params[@"message"] = msgToSend;
[PFCloud callFunctionInBackground:@"sendPushToUser" withParameters:params block:^(id object, NSError *error) {
if (!error) {
// Push sent successfully
NSLog(@"msg posted!");
}
}];
错误:
Error: TypeError: Cannot call method 'indexOf' of undefined
at main.js:15:35 (Code: 141, Version: 1.2.20)
代码main.js如下。
Parse.Cloud.define("sendPushToUser", function(request, response) {
var senderUser = request.user;
var recipientUserId = request.params.recipientId;
var message = request.params.message;
// Validate that the sender is allowed to send to the recipient.
// For example each user has an array of objectIds of friends
if (senderUser.get("friendIds").indexOf(recipientUserId) === -1) {
response.error("The recipient is not the sender's friend, cannot send push.");
}
// Validate the message text.
// For example make sure it is under 140 characters
if (message.length > 140) {
// Truncate and add a ...
message = message.substring(0, 137) + "...";
}
// Send the push.
// Find devices associated with the recipient user
var recipientUser = new Parse.User();
recipientUser.id = recipientUserId;
var pushQuery = new Parse.Query(Parse.Installation);
pushQuery.equalTo("user", recipientUser);
// Send the push notification to results of the query
Parse.Push.send({
where: pushQuery,
data: {
alert: message
}
}).then(function() {
response.success("Push was sent successfully.")
}, function(error) {
response.error("Push failed to send with error: " + error.message);
});
});
以上是写在云main.js代码得到了下面的链接相同的。据我所知,从错误是问题是与friendIds这就是为什么它不调用方法'indexOf'。
从这个链接中获得了想法blog。
'main.js'? 'indexOf'? msgToSend的内容? – 2014-10-17 14:07:17
检查博客链接以了解这些条款。 – 2014-10-17 14:19:52
'main.js'没有在那里定义,因此'indexOf'的使用不能被识别。 *你的*代码使用'msgToSend',它的内容你不提供。 – 2014-10-17 14:43:45
