好，你的第一個目標（允許用戶發送推送通知給其他用戶，並假設你有快遞和MongoDB使Node.js服務器端）嘗試這樣做：
首先在服務器端安裝apn和node-gcm。
npm i --save apn node-gcm
這兩個包用於向ios和android發送推送通知。
一旦你安裝了這些軟件包，請在你的服務器端發送一條路由來發送通知。這可以用的東西就像這樣：
const express = require('express');
const path = require('path');
const gcm = require('node-gcm');
const apn = require('apn');
const apnProvider = new apn.Provider({
token: {
// YOU CAN FOUND THIS KEYS AND THE CERTIFICATE ON APPLE DEVELOPERS SITE
key: path.resolve(__dirname, 'PATH TO YOUR CERTIFICATE.P8'),
keyId: YOUR APN KEY ID,
teamId: YOUR APN TEAM ID,
},
production: false,
});
router.post('/sendNotification', (req, res) => {
const deviceToken = req.body.token;
const message = req.body.message;
const payload = req.body.payload;
const packages = req.body.package;
switch (packages) {
case 'com.foo.bar': {
const notification = new apn.Notification();
notification.topic = 'com.foo.bar';
notification.expiry = Math.floor(Date.now()/1000) + 3600;
notification.badge = 1;
notification.sound = 'ping.aiff';
notification.alert = { message };
notification.payload = { payload };
apnProvider.send(notification, deviceToken).then((result) => {
return result === 200 ? res.sendStatus(200, result) : res.sendStatus(400);
});
break;
}
case 'com.yourteam.foo.bar': {
const androidMessage = new gcm.Message({
priority: 'high',
contentAvailable: true,
delayWhileIdle: false,
timeToLive: 10,
restrictedPackageName: 'com.yourteam.foo.bar',
dryRun: false,
data: {
title: 'foo',
icon: '@mipmap/logo',
notId: parseInt(Math.random() * new Date().getSeconds(), 10),
message,
},
});
const sender = new gcm.Sender(YOUR_KEY);
const registrationTokens = [deviceToken];
sender.send(androidMessage, { registrationTokens }, (err, response) => {
return err ? res.send(err) : res.send(response);
});
break;
}
default:
return res.sendStatus(400);
}
});
現在送你需要做這樣一個POST推送通知：
IOS
目標C
#import <Foundation/Foundation.h>
NSDictionary *headers = @{ @"content-type": @"application/x-www-form-urlencoded",
@"cache-control": @"no-cache"
NSMutableData *postData = [[NSMutableData alloc] initWithData:[@"token=xxxxx" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&message=xxxxx" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&payload=xxxxx" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&package=xxxxx" dataUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://72.89.157.153:3000/notifications/sendNotification"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
[request setHTTPMethod:@"POST"];
[request setAllHTTPHeaderFields:headers];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (error) {
NSLog(@"%@", error);
} else {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
NSLog(@"%@", httpResponse);
}
}];
[dataTask resume];
SWIFT
import Foundation
let headers = [
"content-type": "application/x-www-form-urlencoded",
"cache-control": "no-cache"
]
let postData = NSMutableData(data: "token=xxxxx".data(using: String.Encoding.utf8)!)
postData.append("&message=xxxxx".data(using: String.Encoding.utf8)!)
postData.append("&payload=xxxxx".data(using: String.Encoding.utf8)!)
postData.append("&package=xxxxx".data(using: String.Encoding.utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "http://72.89.157.153:3000/notifications/sendNotification")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
}
})
dataTask.resume()
WEB（AJAX）
var settings = {
"async": true,
"crossDomain": true,
"url": "http://72.89.157.153:3000/notifications/sendNotification",
"method": "POST",
"headers": {
"content-type": "application/x-www-form-urlencoded",
"cache-control": "no-cache"
},
"data": {
"token": "xxxxx",
"message": "xxxxx",
"payload": "xxxxx",
"package": "xxxxx"
}
}
$.ajax(settings).done(function (response) {
console.log(response);
});
JAVA
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(mediaType, "token=xxxxx&message=xxxxx&payload=xxxxx&package=xxxxx");
Request request = new Request.Builder()
.url("http://72.89.157.153:3000/notifications/sendNotification")
.post(body)
.addHeader("content-type", "application/x-www-form-urlencoded")
.addHeader("cache-control", "no-cache")
.build();
Response response = client.newCall(request).execute();
現在，您可以發送推送通知到所有設備。
您的第二個目標可以通過服務器端輕鬆完成，當請求發送到您的URL時，您可以通過POST發送推送通知，例如，如果有人想將您添加爲朋友（讓我們說他們向http://72.89.157.153:3000/friends/ {account_id}）發出了一個請求，您可以向用戶發送通知，告訴他他有新的友誼請求。
它在mongodb上存儲包和用戶令牌的重要性，因此您可以發送正確的通知。
希望它有幫助。
