来自Node.js http库docs:
http.request() returns an instance of the http.ClientRequest class.
The ClientRequest instance is a writable stream. If one needs to upload a file
with a POST request, then write to the ClientRequest object.
但是我不确定如何在我当前的代码中利用它:
var post_data = querystring.stringify({
api_key: fax.api_key,
api_secret: fax.api_secret_key,
to: fax.fax_number,
filename: ""
});
var options = {
host: p_url.hostname.toString(),
path: p_url.path.toString(),
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': post_data.length
}
};
var postReq = http.request(options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('Response: ' + chunk);
});
});
postReq.write(post_data);
postReq.end();

由于您有可写流,因此可以使用write()
,end()
和pipe()
方法。因此,您只需打开一个资源,并将其传递给可写流:
var fs = require('fs');
var stream = fs.createReadStream('./file');
stream.pipe(postReq);
或类似的东西:
var fs = require('fs');
var stream = fs.createReadStream('./file');
stream.on('data', function(data) {
postReq.write(data);
});
stream.on('end', function() {
postReq.end();
});
