我在node.js中寫入了一個GET rest調用。我的郵件調用工作正常,但是當我使用get調用時,我看不到Json格式的輸出。事實上,我看到一些特殊字符的輸出。請告訴我哪裏出錯了。GET Node.js中的其餘調用在JSON中不顯示輸出

var http = require('http'); 
var requestrespone = require("request"); 
var config = require('../config/config.js'); 
var jsonFile = require('jsonfile'); 
var jsonFile=require('../json_input/jsoninput.json'); 
var cheerio =require('cheerio'); 
var express=require('express'); 
var app=express(); 
var postOptions = { 
    host : config.host, 
    method : config.post, 
    path: config.path, 
    headers :config.postheader 
}; 


    var getOptions= 
    { 
     host : config.host, 
     method : config.get, 
     path: config.getpath, 
     headers :config.getheader 

    }; 



jsonObject = JSON.stringify(jsonFile); 


console.info('Options prepared:'); 
console.info(postOptions); 
console.info('Starting the POST call'); 


var jsonString; 
function mapFeedbackIdGeneration(done) 
{ 

    var reqPost = http.request(postOptions, function(res) { 
    console.log("statusCode: ", res.statusCode); 
    res.on('data', function(data) { 
    jsonString=JSON.parse(data); 
    return done(jsonString); 
     }); 

    res.on('close', function() { 
    }); 
}); 


reqPost.write(jsonObject); 
reqPost.end(); 
reqPost.on('error', function(e) { 
console.error(e); 
});} 
///----------GET CALL----------------->>>>> 
console.info('Options prepared:'); 
console.info(getOptions); 

console.info('Do the GET call'); 

var options = { 
    "method": "GET", 
    "hostname": "maphub.cit.api.here.com", 

    "path": "/feedback/-936624", 
    "headers": { 

    'Accept-Encoding':'gzip,deflate', 
    'Authorization':'AWS O7Qx6dyYEnwwBT2Hn5Es:gR/rjtlGsggWEZ1ItPOw0oGXdPM=', 

'Auth-Identifier':'Y-7Wnc2lNk3fMI0n3-rZ', 

'Auth-Service-Id':'here_app', 
'Group-Id':'FGx1AWaAzKOo0imNkLmf', 
'Auth-Secret':'mEv_DZ1JKDDYzESUAp9KyQ', 
'User-Agent':'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0', 

'Host':'maphub.cit.api.here.com' 


} 
}; 

var req = http.request(options, function (res) { 
    var chunks = []; 

    res.on("data", function (chunk) { 
     console.log("chunks data"); 
     console.log(chunks); 
    chunks.push(chunk); 
    }); 

    res.on("end", function() { 
    var body = Buffer.concat(chunks); 
    console.log("hello"+body); 
    }); 
}); 

req.end(); 
module.exports.mapFeedbackIdGeneration=mapFeedbackIdGeneration; 

//module.exports.getMapfeedback=getMapfeedback; 

我的輸出應該是JSON數據,但它表明:

Do the GET call 
chunks data 
[] 
hello▼  T?AO?0►????8?‼?"?*??j↨[email protected]=L?i?%???¶§?⌂?I`w?↨?~??,???  ?.♀???,?

statusCode: 200 

我要去哪裏錯了?

嘗試從獲取選項中刪除''Accept-Encoding':'gzip,deflate'。 –

您的代碼存在問題。在options變量中刪除以下內容。

'Accept-Encoding':'gzip,deflate', 

上面行告訴客戶可以接受gzip壓縮文件,可以解壓遠程服務器。但是,您的應用程序不會執行解壓縮部分。因此,你看到的是亂碼數據。
