Question

我试图在离子应用中设置Mailgun mail service。这是代码：控制器：

$http({
                        "method": "POST",
                        "url": "https://api.mailgun.net/v3/" + mailgunUrl + "/messages",
                        //"crossDomain": "true",
                        "headers": {
                            "Access-Control-Allow-Origin": "*",//"http://localhost:8100",
                            "Access-Control-Allow-Headers": "content-type, accept",
                            //"Access-Control-Allow-Credentials": "true",
                            "Access-Control-Allow-Methods": "GET, POST, PUT, DELETE",
                            "Content-Type": "application/x-www-form-urlencoded",
                            'Authorization' : 'Basic '+ mailgunApiKey
                            //"Authorization": "Basic " + mailgunApiKey//$base64.encode('api:key-'+mailgunApiKey)
                        },
                        data: "from=" + "no-reply@ineevent.com" + "&to=" + $scope.datapopup.mail + "&subject=" + "Guestlist" + "&text="

config.xml中

<content src="main.html"/>
  <access origin="*"/>
  <plugin name="cordova-plugin-whitelist" version="1"/>
  <plugin name="cordova-plugin-crop" spec="~0.1.0"/>
  <allow-navigation href="*" />
  <allow-intent href="*"/>
  <allow-intent href="http://*/*"/>
  <allow-intent href="https://*/*"/>
  <allow-intent href="tel:*"/>
  <allow-intent href="sms:*"/>
  <allow-intent href="mailto:*"/>
  <allow-intent href="geo:*"/>

我收到status '0' error并且日志显示不允许使用CORS（跨域请求），并且缺少access-control-allow-headers（翻译自法语）。

Chrome的另一个错误是'Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.'。

我也尝试过Android设备但是没有用。有什么想法吗？

将此添加到index.html

  <meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">

并将cordova-plugin-whitelist插件添加到您的应用中。

出于开发目的，您可以将CORS plugin用于Chrome。

您的控制器可以是这样的：

.controller("EmailCtrl", function($scope, $http) {

    var mailgunUrl = "YOUR_DOMAIN_HERE";
    var mailgunApiKey = window.btoa("api:key-YOUR_API_KEY_HERE")

    $scope.recipient = "mail@gmail.com";

    $scope.send = function(recipient, subject, message) {
        $http(
            {
                "method": "POST",
                "url": "https://api.mailgun.net/v3/" + mailgunUrl + "/messages",
                "headers": {
                    "Content-Type": "application/x-www-form-urlencoded",
                    "Authorization": "Basic " + mailgunApiKey
                },
                data: "from=" + "ionic@example.com" + "&to=" + recipient + "&subject=" + subject + "&text=" + message
            }
        ).then(function(success) {
            console.log("SUCCESS " + JSON.stringify(success));
        }, function(error) {
            console.log("ERROR " + JSON.stringify(error));
        });
    }

})

答案很简单：

当你从离子运行android时，你不应该使用任何可选参数：离子运行android

Ionic http CORS同源不允许
