json的輸出不正確

Question

我正在嘗試使用JSON.stringify來使我的json對象可讀。
但是，它不起作用。任何人都可以幫助我看看我做錯了什麼嗎？

var request = require('request'); 

var options = { 
    url: 'https://api.github.com/repos/benjaminsunderland/TicTacToe/stats/commit_activity', 
    headers: { 
    'User-Agent': 'request' 
    } 
}; 

function callback(error, response, body) { 
     console.log(JSON.stringify(body, null, 2)); 
} 

request(options, callback); 

輸出應沿着線：根據文件

[ 
    { 
    "days": [ 
     0, 
     3, 
     26, 
     20, 
     39, 
     1, 
     0 
    ], 
    "total": 89, 
    "week": 1336280400 
    } 
]

但是，我得到：

Answer 1

在你的回調函數的變量body包含字符串值（不是一個有效的JSON本身）。
這就是爲什麼JSON.stringify()無法以您想要的方式進行格式化的原因。

您應該先使用JSON.parse()函數將其轉換爲JSON。

這裏是你的代碼，提供給body所提到的功能：

var request = require('request'); 

var options = { 
    url: 'https://api.github.com/repos/benjaminsunderland/TicTacToe/stats/commit_activity', 
    headers: { 
    'User-Agent': 'request' 
    } 
}; 

function callback(error, response, body) { 
     var jsonBody = JSON.parse(body); 
     console.log(JSON.stringify(jsonBody, null, 2)); 
} 

request(options, callback);
