Question

无法找到我的req对象有什么问题。尝试在回调中发送推送通知时出现此错误。试图使用jslint.com链接我的请求数据，没有任何问题。为此已经抓了好几个小时！

{＆＃34; link＆＃34;：null，＆＃34; message＆＃34;：＆＃34;请求正文中的JSON无效。为空 JSON，传递＆＃39; {}＆＃39;。＆＃34;，＆＃34;输入＆＃34;：＆＃34; UnprocessableEntity＆＃34;}

我的代码如下：

var title = req.body.title,
  message = req.body.message;

// Define relevant info
var ionic_api_token = 'eyJ0eXAiOTdGb-xQVQaD2sV7qTh7XNKCnwiJKV1QiLJhbGciOiJIUzI1NiJ9.eyJqdGkiOiI2MjiNC03YjE5LTQ3MzMtYjJhMy0zM2Y3MjBkYzU4MjcifQ.s3e6pCwlVUBAs8kvbO';
var device_tokens = ['d44pDarVamnNJS2cNJ2modyBxjZZxcHLlnhQN4wZkJdbgkOw96rq9EEv2WCA5MKU6do0pJoO5rsmQsBAecFt4OIFB0hhD4Dp2K-uMbjum828j-8LKtpCTtGoIDBUvYI6L'];
var ionic_security_profile = 'main';

// Build the request object
var req = {
  method: 'POST',
  url: 'https://api.ionic.io/push/notifications',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer ' + ionic_api_token
  },
  data: {
    "tokens": device_tokens,
    "profile": ionic_security_profile,
    "notification": {
      "title": title,
      "message": message,
      "android": {
        "title": title,
        "message": message
      },
      "ios": {
        "title": title,
        "message": message
      }
    }
  }
};

function callback(error, response, body) {
  console.log(body)
}

request(req, callback);

});

唯一可能导致问题的是标题＆amp;消息对象（可能是字符串）。请尝试转义它，如下所示

function escapeJson(json) {
   return JSON.parse(JSON.stringify(json));
}

title = escapeJson(title);
message = escapeJson(message);

var req = {
  method: 'POST',
  url: 'https://api.ionic.io/push/notifications',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer ' + ionic_api_token
  },
  data: {
    "tokens": device_tokens,
    "profile": ionic_security_profile,
    "notification": {
      "title": title,
      "message": message,
      "android": {
        "title": title,
        "message": message
      },
      "ios": {
        "title": title,
        "message": message
      }
    }
  }
};

请求正文中使用离子推送的json无效
