I am planning to integrate the IBM Watson Document Conversion service
with Salesforce.
From there I am unable to send my pdf file directly to Watson and I'm getting Media Type not supported.
I am also getting this error:
{
"code" : 500 ,
"error" : "Server Error" ,
"description" : "2017-07-18T06:02:19-04:00, Error WATSNGWERR-0x0113001c occurred when accessing https://gateway.watsonplatform.net/document-conversion/api/v1/convert_document?version=2015-12-15&config="{"conversion_target":"answer_units"}", Tran-Id: gateway-dp02-1967135880 - Watson Gateway Error"
}
Here is the code I'm using:
public class Resume {
String boundary = '----------------------------741e90d31eff';
public string id{get;set;}
public string content{get;set;}
Transient public Attachment att{set;get;}
public Resume(ApexPages.StandardController controller) {
id=ApexPages.currentPage().getParameters().get('id');
att=new Attachment();
att=[Select Id,ParentId, Name,body,ContentType From Attachment where ParentId=:id limit 1];
content=String.valueOf(att.body);
System.debug('---->' + content);
String header = '--' + boundary + '\nContent-Disposition: form-data; name="att"; filename="'+att.name+'";\nContent-Type: application/pdf';
String footer = '--' + boundary + '--';
String headerEncoded =
EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
String bodyEncoded = EncodingUtil.base64Encode(att.body);
Blob bodyBlob = null;
String last4Bytes =
bodyEncoded.substring(bodyEncoded.length() - 4, bodyEncoded.length());
while (headerEncoded.endsWith('=')){
header+=' ';
headerEncoded = EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
}
if (last4Bytes.endsWith('==')) {
last4Bytes = last4Bytes.substring(0,2) + '0K';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded + bodyEncoded + footerEncoded);
} else if (last4Bytes.endsWith('=')) {
last4Bytes = last4Bytes.substring(0,3) + 'N';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;
footer = '\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded + bodyEncoded + footerEncoded);
} else {
footer = '\r\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded + bodyEncoded + footerEncoded);
}
String configAsString ='\"conversion_target:answer_units\"';
Http h = new Http();
HttpRequest request = new HttpRequest();
request.setMethod('POST');
request.setHeader('Content-Type','multipart/form-data; boundary=' + boundary);
String username= 'DOCUMENT-CONVERSION-USERNAME';
String password= 'DOCUMENT-CONVERSION-PASSWORD';
request.setHeader('Authorization', 'Basic ' + EncodingUtil.base64Encode(blob.valueOf(username + ':' + password)));
request.setEndpoint('https://gateway.watsonplatform.net/document-conversion/api/v1/convert_document?version=2015-12-15&config='+configAsString);
request.setBodyAsBlob(bodyBlob);
request.setCompressed(true);
HttpResponse response = h.send(request);
System.debug(response.getBody());
}
}
You are sending the config as a query parameter, but it should be in the body.
Here is the curl command that makes what you are trying to do:
curl -X POST \
-u "{username}":"{password}" \
-F config="{\"conversion_target\":\"answer_units\"}" \
-F "file=#sample.pdf;type=application/pdf" \
"https://gateway.watsonplatform.net/document-conversion/api/v1/convert_document?version=2015-12-15"
I also think there is an error in the way you are creating the body. My team built an SDK to use the Watson APIs in the Salesforce environment. I would suggest you take a look.
If you can't deploy the SDK to your Salesforce organization (It's a lot of code), copy the code from the IBMWatsonMultipartBody.cls class. It will help you encode an Attachment as base64 so that you can end it to Watson.
UPDATE: The Document Conversion service was deprecated but the features from that service were enhanced and migrated to the Discovery service
I need to get LookUpId of a user in SharePoint 2010 using client object model. I am able to get it using EnsureUser method, but this method adds the user to the SharePoint web site if the user is not available to the site.My requirement is get the LookupId without adding the user to SharePoint
Is there a alternative way to get the LookupId without using EnsureUser method?
If not, after getting the LookupId using EnsureUser method, can we remove the user from the SharePoint site?
Appreciate your suggestions.
Web.SiteUserInfoList Property gets the UserInfo list of the site collection that contains the Web site.
The following code demonstrates how to get userInfo (including userId property) by userName:
function getUserInfo(userName,Success,Error)
{
var context = new SP.ClientContext.get_current();
var userInfoList = context.get_web().get_siteUserInfoList();
var query = new SP.CamlQuery();
var viewXml = "<View> \
<Query> \
<Where> \
<Eq><FieldRef Name='UserName' /><Value Type='Text'>" + userName + "</Value></Eq> \
</Where> \
</Query> \
<RowLimit>1</RowLimit> \
</View>";
query.set_viewXml(viewXml);
var items = userInfoList.getItems(query);
context.load(items,'Include(Deleted,Department,EMail,FirstName,ID,IsActive,IsSiteAdmin,JobTitle,LastName,MobilePhone,Name,Notes,Office,Picture,SipAddress,UserName,WebSite,WorkPhone)');
context.executeQueryAsync(function(){
if(items.get_count() > 0) {
var item = items.itemAt(0);
Success(item.get_fieldValues());
}
else {
Success(null);
}
},
Error
);
}
//Usage
getUserInfo('username#tenant.onmicrosoft.com',function(userInfo){
console.log('User Id: ' + userInfo.ID);
},
function(sender,args){
console.log(args.get_message());
});
I want to know how can I use Google Text-to-Speech API in my .NET project. I think I need to call a URL to use the web service, but the idea for me is not clear. Can anyone help?
Old answer:
Try using this URL:
http://translate.google.com/translate_tts?tl=en&q=Hello%20World
It will automatically generate a wav file which you can easily get with an HTTP request through any .net programming.
Edit:
Ohh Google, you thought you could prevent people from using your wonderful service with flimsy http header verification.
Here is a solution to get a response in multiple languages (I'll try to add more as we go):
NodeJS
// npm install `request`
const fs = require('fs');
const request = require('request');
const text = 'Hello World';
const options = {
url: `https://translate.google.com/translate_tts?ie=UTF-8&q=${encodeURIComponent(text)}&tl=en&client=tw-ob`,
headers: {
'Referer': 'http://translate.google.com/',
'User-Agent': 'stagefright/1.2 (Linux;Android 5.0)'
}
}
request(options)
.pipe(fs.createWriteStream('tts.mp3'))
Curl
curl 'https://translate.google.com/translate_tts?ie=UTF-8&q=Hello%20Everyone&tl=en&client=tw-ob' -H 'Referer: http://translate.google.com/' -H 'User-Agent: stagefright/1.2 (Linux;Android 5.0)' > google_tts.mp3
Note that the headers are based on #Chris Cirefice's example, if they stop working at some point I'll attempt to recreate conditions for this code to function. All credits for the current headers go to him and the wonderful tool that is WireShark. (also thanks to Google for not patching this)
In an update to Schahriar SaffarShargh's answer, Google has recently implemented a 'Google abuse' feature, making it impossible to send just any regular old HTTP GET to a URL such as:
http://translate.google.com/translate_tts?tl=en&q=Hello%20World
which worked just fine and dandy previously. Now, following such a link presents you with a CAPTCHA. This also affects HTTP GET requests out-of-browser (such as with cURL), because using that URL gives a redirect to the abuse protection page (the CAPTCHA).
To start, you have to add the query parameter client to the request URL:
http://translate.google.com/translate_tts?tl=en&q=Hello%20World&client=t
Google Translate sends &client=t, so you should too.
Before you make that HTTP request, make sure that you set the Referer header:
Referer: http://translate.google.com/
Evidently, the User-Agent header is also required, but interestingly enough it can be blank:
User-Agent:
Edit: NOTE - on some user-agents, such as Android 4.X, the custom User-Agent header is not sent, meaning that Google will not service the request. In order to solve that problem, I simply set the User-Agent to a valid one, such as stagefright/1.2 (Linux;Android 5.0). Use Wireshark to debug requests (as I did) if Google's servers are not responding, and ensure that these headers are being set properly in the GET! Google will respond with a 503 Service Unavailable if the request fails, followed by a redirect to the CAPTCHA page.
This solution is a bit brittle; it is entirely possible that Google will change the way they handle these requests in the future, so in the end I would suggest asking Google to make a real API endpoint (free or paid) that we can use without feeling dirty for faking HTTP headers.
Edit 2: For those interested, this cURL command should work perfectly fine to download an mp3 of Hello in English:
curl 'http://translate.google.com/translate_tts?ie=UTF-8&q=Hello&tl=en&client=t' -H 'Referer: http://translate.google.com/' -H 'User-Agent: stagefright/1.2 (Linux;Android 5.0)' > google_tts.mp3
As you may notice, I have set both the Referer and User-Agent headers in the request, as well as added the client=t parameter to the querystring. You may use https instead of http, your choice!
Edit 3: Google now requires a token for each GET request (noted by tk in the querystring). Below is the revised cURL command that will correctly download a TTS mp3:
curl 'https://translate.google.com/translate_tts?ie=UTF-8&q=hello&tl=en&tk=995126.592330&client=t' -H 'user-agent: stagefright/1.2 (Linux;Android 5.0)' -H 'referer: https://translate.google.com/' > google_tts.mp3
Notice the &tk=995126.592330 in the querystring; this is the new token. I obtained this token by pressing the speaker icon on translate.google.com and looking at the GET request. I simply added this querystring parameter to the previous cURL command, and it works.
NOTE: obviously this solution is very frail, and breaks at the whim of the architects at Google who introduce new things like tokens required for the requests. This token may not work tomorrow (though I will check and report back)... the point is, it is not wise to rely on this method; instead, one should turn to a commercial TTS solution, especially if using TTS in production.
For further explanation of the token generation and what you might be able to do about it, see Boude's answer.
If this solution breaks any time in the future, please leave a comment on this answer so that we can attempt to find a fix for it!
Expanding on Chris' answer. I managed to reverse engineer the token generation process.
The token for the request is based on the text and a global TKK variable set in the page script. These are hashed in JavaScript thus resulting in the tk param.
Somewhere in the page script you will find something like this:
TKK='403413';
This is the amount of hours passed since epoch.
The text is pumped in the following function (somewhat deobfuscated):
var query = "Hello person";
var cM = function(a) {
return function() {
return a
}
};
var of = "=";
var dM = function(a, b) {
for (var c = 0; c < b.length - 2; c += 3) {
var d = b.charAt(c + 2),
d = d >= t ? d.charCodeAt(0) - 87 : Number(d),
d = b.charAt(c + 1) == Tb ? a >>> d : a << d;
a = b.charAt(c) == Tb ? a + d & 4294967295 : a ^ d
}
return a
};
var eM = null;
var cb = 0;
var k = "";
var Vb = "+-a^+6";
var Ub = "+-3^+b+-f";
var t = "a";
var Tb = "+";
var dd = ".";
var hoursBetween = Math.floor(Date.now() / 3600000);
window.TKK = hoursBetween.toString();
fM = function(a) {
var b;
if (null === eM) {
var c = cM(String.fromCharCode(84)); // char 84 is T
b = cM(String.fromCharCode(75)); // char 75 is K
c = [c(), c()];
c[1] = b();
// So basically we're getting window.TKK
eM = Number(window[c.join(b())]) || 0
}
b = eM;
// This piece of code is used to convert d into the utf-8 encoding of a
var d = cM(String.fromCharCode(116)),
c = cM(String.fromCharCode(107)),
d = [d(), d()];
d[1] = c();
for (var c = cb + d.join(k) +
of, d = [], e = 0, f = 0; f < a.length; f++) {
var g = a.charCodeAt(f);
128 > g ? d[e++] = g : (2048 > g ? d[e++] = g >> 6 | 192 : (55296 == (g & 64512) && f + 1 < a.length && 56320 == (a.charCodeAt(f + 1) & 64512) ? (g = 65536 + ((g & 1023) << 10) + (a.charCodeAt(++f) & 1023), d[e++] = g >> 18 | 240, d[e++] = g >> 12 & 63 | 128) : d[e++] = g >> 12 | 224, d[e++] = g >> 6 & 63 | 128), d[e++] = g & 63 | 128)
}
a = b || 0;
for (e = 0; e < d.length; e++) a += d[e], a = dM(a, Vb);
a = dM(a, Ub);
0 > a && (a = (a & 2147483647) + 2147483648);
a %= 1E6;
return a.toString() + dd + (a ^ b)
};
var token = fM(query);
var url = "https://translate.google.com/translate_tts?ie=UTF-8&q=" + encodeURI(query) + "&tl=en&total=1&idx=0&textlen=12&tk=" + token + "&client=t";
document.write(url);
I managed to successfully port this to python in my fork of gTTS, so I know this works.
Edit: By now the token generation code used by gTTS has been moved into gTTS-token.
Edit 2: Google has changed the API (somewhere around 2016-05-10), this method requires some modification. I'm currently working on this. In the meantime changing the client to tw-ob seems to work.
Edit 3:
The changes are minor, yet annoying to say the least. The TKK now has two parts. Looking something like 406986.2817744745. As you can see the first part has remained the same. The second part is the sum of two seemingly random numbers. TKK=eval('((function(){var a\x3d2680116022;var b\x3d137628723;return 406986+\x27.\x27+(a+b)})())'); Here \x3d means = and \x27 is '. Both a and b change every UTC minute. At one of the final steps in the algorithm the token is XORed by the second part.
The new token generation code is:
var xr = function(a) {
return function() {
return a
}
};
var yr = function(a, b) {
for (var c = 0; c < b.length - 2; c += 3) {
var d = b.charAt(c + 2)
, d = "a" <= d ? d.charCodeAt(0) - 87 : Number(d)
, d = "+" == b.charAt(c + 1) ? a >>> d : a << d;
a = "+" == b.charAt(c) ? a + d & 4294967295 : a ^ d
}
return a
};
var zr = null;
var Ar = function(a) {
var b;
if (null !== zr)
b = zr;
else {
b = xr(String.fromCharCode(84));
var c = xr(String.fromCharCode(75));
b = [b(), b()];
b[1] = c();
b = (zr = window[b.join(c())] || "") || ""
}
var d = xr(String.fromCharCode(116))
, c = xr(String.fromCharCode(107))
, d = [d(), d()];
d[1] = c();
c = "&" + d.join("") +
"=";
d = b.split(".");
b = Number(d[0]) || 0;
for (var e = [], f = 0, g = 0; g < a.length; g++) {
var l = a.charCodeAt(g);
128 > l ? e[f++] = l : (2048 > l ? e[f++] = l >> 6 | 192 : (55296 == (l & 64512) && g + 1 < a.length && 56320 == (a.charCodeAt(g + 1) & 64512) ? (l = 65536 + ((l & 1023) << 10) + (a.charCodeAt(++g) & 1023),
e[f++] = l >> 18 | 240,
e[f++] = l >> 12 & 63 | 128) : e[f++] = l >> 12 | 224,
e[f++] = l >> 6 & 63 | 128),
e[f++] = l & 63 | 128)
}
a = b;
for (f = 0; f < e.length; f++)
a += e[f],
a = yr(a, "+-a^+6");
a = yr(a, "+-3^+b+-f");
a ^= Number(d[1]) || 0;
0 > a && (a = (a & 2147483647) + 2147483648);
a %= 1E6;
return c + (a.toString() + "." + (a ^ b))
}
;
Ar("test");
Of course I can't generate a valid url anymore, since I don't know how a and b are generated.
An additional alternative is: responsivevoice.org a simple example JsFiddle is Here
HTML
<div id="container">
<input type="text" name="text">
<button id="gspeech" class="say">Say It</button>
<audio id="player1" src="" class="speech" hidden></audio>
</div>
JQuery
$(document).ready(function(){
$('#gspeech').on('click', function(){
var text = $('input[name="text"]').val();
responsiveVoice.speak("" + text +"");
<!-- http://responsivevoice.org/ -->
});
});

i have created this like : q= urlencode & tl = language name
Just try this :
https://translate.google.com.vn/translate_tts?ie=UTF-8&q=%E0%A6%86%E0%A6%AE%E0%A6%BF%20%E0%A6%A4%E0%A7%8B%E0%A6%AE%E0%A6%BE%E0%A6%AF%E0%A6%BC%20%E0%A6%AD%E0%A6%BE%E0%A6%B2%E0%A7%8B%E0%A6%AC%E0%A6%BE%E0%A6%B8%E0%A6%BF+&tl=bn&client=tw-ob
Allright, so Google has introduces tokens (see the tk parameter in the new url) and the old solution doesn't seem to work. I've found an alternative - which I even think is better-sounding, and has more voices! The command isn't pretty, but it works. Please note that this is for testing purposes only (I use it for a little domotica project) and use the real version from acapella-group if you're planning on using this commercially.
curl $(curl --data 'MyLanguages=sonid10&MySelectedVoice=Sharon&MyTextForTTS=Hello%20World&t=1&SendToVaaS=' 'http://www.acapela-group.com/demo-tts/DemoHTML5Form_V2.php' | grep -o "http.*mp3") > tts_output.mp3
Some of the supported voices are;
Sharon
Ella (genuine child voice)
EmilioEnglish (genuine child voice)
Josh (genuine child voice)
Karen
Kenny (artificial child voice)
Laura

It also supports multiple languages and more voices - for that I refer you to their website; http://www.acapela-group.com/
You can download the Voice using Wget:D
wget -q -U Mozilla "http://translate.google.com/translate_tts?tl=en&q=Hello"
Save the output into a mp3 file:

I think you'll understand this
if didn't then use vbscript to vb/C# converter.
still didn't then contact Me.
I have done this before ,can't find the code now that this why i'm not directly givin' you the code.
Because it came up in chat here , and the first page for googeling was this one, i decided to let all in on my findings googling some more XD
you really dont need to go any length anymore to make it work simply stand on the shoulders of giants:
there is a standard

The 2023 Answer:
There's a Google Text to Speech Service in Google Cloud. It is an API service. To use it, you must first enable the Text-to-Speech API in Google Console.
Next, go to APIs & Services > Credentials and create a new API Key (Create Credentials > API Key).
Finally, you can call the POST API endpoint https://texttospeech.googleapis.com/v1/text:synthesize?key=[API KEY]
{ "audioConfig": { "audioEncoding": "LINEAR16", "pitch": "0.00", "speakingRate": "1.00" }, "input": { "text": "Hello World" }, "voice": { "languageCode": "en-US", "name": "en-US-Wavenet-E" } }
