Oauth not working request with headers.Accept='application/pdf'

[Miguel Gil]

I am trying to GET some content in 'application/pdf' format (PDF 1.4). I specify in the headers headers.Accept='application/pdf' and I get content that display an empty file in any PDF viewer but the file is not empty. Have a look at this code in lib/oauth.js:

if ($this.clientOptions.detectResponseContentType && utils.isBinaryContent(response)) {
data = new Buffer(0);
type = 1;
output = response;
} else if (response.headers['content-encoding'] === 'gzip') {
var gunzip = zlib.createGunzip();
data = new Buffer(0);
type = 2;
response.pipe(gunzip);
output = gunzip;
} else {
response.setEncoding('utf8');
data = "";
output = response;
}

$this.clientOptions.detectResponseContentType is undefined and it is not documented what it does or how to set it up anyway.
In regards to isBinaryContent function it returns false for PDF.
So it is the else what it is run, so we run this line:
response.setEncoding('utf8')

I have fixed it locally by adding this:
if ($this.clientOptions.detectResponseContentType && utils.isBinaryContent(response)) {
data = new Buffer(0);
type = 1;
output = response;
} else if (response.headers['content-encoding'] === 'gzip') {
var gunzip = zlib.createGunzip();
data = new Buffer(0);
type = 2;
response.pipe(gunzip);
output = gunzip;
} else if (headers.Accept=='application/pdf') {
data = new Buffer(0);
type = 1;
output = response;
} else {
response.setEncoding('utf8');
data = "";
output = response;
}

This is more a hack than a solution but I am not sure is PDF is binary file format and I am not sure how do you use $this.clientOptions.detectResponseContentType.

I check for text based entities instead of binary now. And you can set that through the setClientOptions function.

I don't think I documented this because it's very advanced.

OAuth.prototype.setClientOptions = function (options) {
  this.clientOptions = utils.extend(this._clientOptions, options);
};

You missed a closing parethensis:

utils.isBinaryContent = function (response) {
return (!response.headers || !response.headers["content-type"])
? false
: (response.headers["content-type"].match(/^(text|html|json|doc|xml|html|rss|form|javascript|ecmascript)/)
? false
: true;
};

Should be:
: true);
};

Ah thank you
