javascript - 读取 REST POST 响应 node.js

Question

我可以在休息客户端中测试后调用，其 header 显示为:

Cache-Control: no-cache, no-store, must-revalidate
Connection: keep-alive
Content-Encoding: gzip
Content-Language: en
Content-Length: 49
Content-Type: application/json
Date: Fri, 14 Apr 2017 21:05:42 GMT

我调用帖子的代码如下:

var https = require('https');
... var jsonObject = JSON.stringify({
            "Name" : optyName
        });

        // prepare the header
        var postheaders = {
            'Content-Type' : 'application/vnd.oracle.adf.resourceitem+json',
            'authorization' : 'Basic am9obi5kdW5iYXI6dnBoODk1ODM=',
            gzip: true
        };

        // the post options
        var optionspost = {
            host : 'myhost',
            port : 443,
            path : '/salesApi/resources/11.1.11/opportunities?fields=OptyId&onlyData=true',
            method : 'POST',
            headers : postheaders,
        };

        // do the POST call
        var reqPost = https.request(optionspost, function(error,response,body) {
             console.log('the decoded data is: ' + body)
         });

  reqPost.write(jsonObject);
        reqPost.end();
}

但是我得到了打印的东西:

the decoded data is: undefined

Answer 1

var http = require("http"), zlib = require("zlib");

函数 getGzipped(url, 回调) { //存储流式解压的缓冲区 var 缓冲区 = [];

http.get(url, function(res) {
    // pipe the response into the gunzip to decompress
    var gunzip = zlib.createGunzip();            
    res.pipe(gunzip);

    gunzip.on('data', function(data) {
        // decompression chunk ready, add it to the buffer
        buffer.push(data.toString())

    }).on("end", function() {
        // response and decompression complete, join the buffer and return
        callback(null, buffer.join("")); 

    }).on("error", function(e) {
        callback(e);
    })
}).on('error', function(e) {
    callback(e)
});

}

getGzipped(url, 函数(错误, 数据) { 控制台.log(数据);});
