Question

将节点js中的https请求发送到休息服务的步骤是什么？我有一个api暴露像https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school

如何传递请求以及我需要为此API提供哪些选项主机，端口，路径和方法？

Answer 1

只需将核心https模块与https.request函数一起使用即可。 POST请求的示例（GET将类似）：

var https = require('https');

var options = {
  host: 'www.google.com',
  port: 443,
  path: '/upload',
  method: 'POST'
};

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

最简单的方法是使用request模块。

request('https://example.com/url?a=b', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }
});

使用请求模块解决了问题。

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );

Answer 4

请注意，如果您使用的是MatrixCursor suggestionsCursor = new MatrixCursor(new String[]{BaseColumns._ID, COLUMN_FIELD_NO}); Observable.fromIterable(data) .filter(it->it!=null && it.toLowerCase().contains(newText.toLowerCase())) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .toList() .subscribe(strings -> { int key = 0; for (String suggestion : strings) { suggestionsCursor.addRow(new Object[]{key++, suggestion}); } });，请不要直接使用https.request中的正文。如果您有大量数据成块进入，这将失败。因此，您需要连接所有数据，然后在res.on('data',..中处理响应。示例-

res.on('end'

你可以使用superagent和节点的url模块建立一个这样的请求：

var request = require('superagent');
var url = require('url');

var urlObj = {
  protocol: 'https',
  host: '133-70-97-54-43.sample.com',
  pathname: '/feedSample/Query_Status_View/Query_Status/Output1'
};

request
  .get(url.format(urlObj))
  .query({'STATUS': 'Joined school'})
  .end(function(res) {
    if (res.ok) {
      console.log(res.body);
    }
  });
