返回结果

getMissingTransactions调用返回一个JSON对象,其结构如下:

  • hashes:缺失的交易哈希数组
  • duration:请求执行用时,单位:毫秒

 "hashes": [],
 "duration": 0
}

调用失败的HTTP状态码为400,响应示例如下:

{
  "error": "'command' parameter has not been specified"
}

示例代码

Python

import urllib2
import json

command = {"command": "getMissingTransactions"}

stringified = json.dumps(command)

headers = {
    'content-type': 'application/json',
    'X-IOTA-API-Version': '1'
}

request = urllib2.Request(url="http://localhost:14265", data=stringified, headers=headers)
returnData = urllib2.urlopen(request).read()

jsonData = json.loads(returnData)

print jsonData

Node.js

var request = require('request');

var command = {"command": "getMissingTransactions"}

var options = {
  url: 'http://localhost:14265',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
        'X-IOTA-API-Version': '1',
    'Content-Length': Buffer.byteLength(JSON.stringify(command))
  },
  json: command
};

request(options, function (error, response, data) {
  if (!error && response.statusCode == 200) {
    console.log(data);
  }
});

命令行

curl http://localhost:14265 \
