如何在请求的模块响应中解压缩压缩的正文?
我已经在网上尝试了几个示例,但是似乎都没有用。
request(url, function(err, response, body) {
if(err) {
handleError(err)
} else {
if(response.headers['content-encoding'] == 'gzip') {
// How can I unzip the gzipped string body variable?
// For instance, this url:
// http://highsnobiety.com/2012/08/25/norse-projects-fall-2012-lookbook/
// Throws error:
// { [Error: incorrect header check] errno: -3, code: 'Z_DATA_ERROR' }
// Yet, browser displays page fine and debugger shows its gzipped
// And unzipped by browser fine...
if(response.headers['content-encoding'] && response.headers['content-encoding'].toLowerCase().indexOf('gzip') > -1) {
var body = response.body;
zlib.gunzip(response.body, function(error, data) {
if(!error) {
response.body = data.toString();
} else {
console.log('Error unzipping:');
console.log(error);
response.body = body;
}
});
}
}
}
}
