In the below function, I got an error response from Twitter as "Bad request". Please help me to solve this.

//param1 file === DriveApp.getFileById()
//param2 init === returned object of initTwitterUpload function
//param3 service === OAuth1.createService()
function appendTwitterUpload(file,init,service) {
  var blob = file.getBlob()
  var bytes = blob.getBytes()
  var base64Blob = Utilities.base64Encode(bytes)
  var metaData = {name: file.getName(),
    mimeType: file.getMimeType()}
  var baseUrl =  "https://upload.twitter.com/1.1/media/upload.json" //?command=APPEND&media_id=" 
    //Oauth1percentEncode(init["media_id_string"])    "&segment_index="   Oauth1percentEncode(0);
  var options = {method:'POST',
                 contentType : 'multipart/form-data',
                 payload : {'command':'APPEND',
                            'media_id' : init["media_id"],
                            'segment_index': 0,
                           },
                 files:{'media': bytes},
                 muteHttpExceptions:true}
  var response = service.fetch(baseUrl,options);
  return JSON.parse(response.getContentText())
}

I appreciate a quick fix. any Twitter developer out there finding bugs, I have found one with Google apps script. I am using OAuth 1.0a authentication and following all the procedures mentioned in the documentation correctly. Please give an exact fix for the above function. I am using Urlfetchapp for posting the payload with content-type of multipart/form-data. Service param here is nothing but urlfetchapp with required authentication headers that is available in Oauth 1 library

/Twitter file upload - init -->append -->finalize/ initTwitterUpload function is working perfectly. Service param is a urlfetchapp with authorization headers and matches with one of the functions in the oauth1 library(fetch)

Other functions in my gs file:

function uploadTwitterMedia(mediaUrl){
    var file = DriveApp.getFileById(mediaUrl.replace("https://drive.google.com/open?id=",""))
    var initResponse = initTwitterUpload(mediaUrl,service)
    var appendResponse = appendTwitterUpload(file,initResponse,service)
    var finalizeResponse = finalizeTwitterUpload(initResponse,service)
    return initResponse["media_id_string"]
}

function initTwitterUpload(url,service){
  var file = DriveApp.getFileById(url.replace("https://drive.google.com/open?id=",""))
  var type = file.getMimeType()
  var size = file.getSize()
  var baseUrl =  "https://upload.twitter.com/1.1/media/upload.json?"
  var oauthParams = "command=INIT&total_bytes=" encodeURIComponent(size).replace(/\!/g, "!")
  .replace(/\*/g, "*")
  .replace(/\'/g, "'")
  .replace(/\(/g, "(")
  .replace(/\)/g, ")") "&media_type=" encodeURIComponent(type).replace(/\!/g, "!")
  .replace(/\*/g, "*")
  .replace(/\'/g, "'")
  .replace(/\(/g, "(")
  .replace(/\)/g, ")") "&media_category="  Oauth1percentEncode("TWEET_IMAGE");
  var tweetUrl = baseUrl   oauthParams 
  var response = service.fetch(tweetUrl,{method:'POST'})
  return JSON.parse(response.getContentText())
}



function finalizeTwitterUpload(init,service){
  var baseUrl =  "https://upload.twitter.com/1.1/media/upload.json?"
  var params = "command=FINALIZE&media_id=" Oauth1percentEncode(init["media_id_string"])
  var tweetUrl = baseUrl   params 
  var response = service.fetch(tweetUrl,{method:'POST',
                                        muteHttpExceptions:true})
  return JSON.parse(response.getContentText())
}


function Oauth1percentEncode(text){
  text = encodeURIComponent(text).replace(/\!/g, "!").replace(/\*/g, "*").replace(/\'/g, "'")
  .replace(/\(/g, "(");
  return text
}

Also, the statusTwitterUpload function is not working as expected, it gives a response as "Page not found".I appreciate any kind of help.

CodePudding user response：

I found an answer. Thanks to me

function appendTwitterUpload(file,init,service) {
  var options = null
  var response = null
  var baseUrl = "https://upload.twitter.com/1.1/media/upload.json?command=APPEND&media_id="   init["media_id_string"]  
    "&segment_index="   Oauth1percentEncode(0);
  var boundary = "xxxxxxxxxx";
  var data = "";
  data  = "--"   boundary   "\r\n";
  data  = "Content-Disposition: form-data; name=\"media\"; filename=\""   file.getName()   "\"\r\n";
  data  = "Content-Type:"   file.getMimeType()   "\r\n\r\n";
  
  //retry fracemork for  drive service error
  var getPayload = partial (function(data,file,boundary){ return Utilities.newBlob(data).getBytes()
  .concat(file.getBlob().getBytes())
  .concat(Utilities.newBlob("\r\n--"   boundary   "--").getBytes());},data,file,boundary)
  var payload = executeWithRetry(getPayload,3)
  
  var options = {
    method : "post",
    contentType : "multipart/form-data; boundary="   boundary,
    payload : payload,
      muteHttpExceptions: true,
}
var response = service.fetch(baseUrl,options);
console.log("response---_>", response.getResponseCode());
return response.getResponseCode()
}

Replace appendTwitterUpload with the function in the answer
