I am using the textlocal short url API with the signed URL that I have generated for a Cloud Storage blob. I am getting MalformedSecurityHeader error in the browser when I use the short URL. I tried the same API with other random links and it worked fine. Can I get some help on this.
def shorten_url(apikey, url):
data = urllib.parse.urlencode({'apikey': apikey, 'url': url})
data = data.encode('utf-8')
request = urllib.request.Request("https://api.textlocal.in/create_shorturl/")
f = urllib.request.urlopen(request, data,
context=ssl.create_default_context(cafile=certifi.where()))
fr = f.read()
return(fr)
I was able to resolve this. data = urllib.parse.urlencode({'apikey': apikey, 'url': urllib.parse.quote(url)})

I am trying to connect to a webservice through Power BI but I still do not achieve result, first try to use the Web data source and with the Advanced Use add the Header that in my case is Content-Type and its value is application/json and additional as Body I have a token
Where I get as a result the following:
Additional also try to use as source "Blank Query", where I accessed the advanced editor section and add the following Query:
I get as an error the following:
To make sure that the Webservice works correctly and obtains a result I have used the Advanced REST Client tool and I have made the following configuration:
Where you can see that the Headers section I have added the Header name Content-Type and the value of the Header Value is application/json, in the Body section is where I have added the token
With this I realize that my Webservice gets an answer and that the service is working correctly, I would like someone to give me a little guidance in a short time to perform correctly
Supply the content to switch the method from GET to POST eg
Perform a POST against a URL, passing a binary JSON payload and
parsing the response as JSON.
https://learn.microsoft.com/en-us/powerquery-m/web-contents#example-2
let
url = "https://postman-echo.com/post",
headers = [#"Content-Type" = "application/json"],
postData = Json.FromValue([token = "abcdef"]),
response = Web.Contents(
url,
[
Headers = headers,
Content = postData
]
),
jsonResponse = Json.Document(response),
json = jsonResponse[json]
in
json
or
let
url = "https://postman-echo.com/post",
headers = [#"Content-Type" = "application/json"],
postData = Text.ToBinary("{ ""token"":""abcdef""}"),
response = Web.Contents(
url,
[
Headers = headers,
Content = postData
]
),
jsonResponse = Json.Document(response),
json = jsonResponse[json]
in
json
I am trying to send multiple images to the backend server.
I have tried Dio and Http but the server responds with an error and the rest of the data except the images get saved.
The documentation says that the key values must be 'images_0' 'images_1' and so on.
Code -
The images are converted from XFile to multipart file.
int imgNum = 0;
for (int i = 0; i < data.images.length; i++) {
if (data.images[i] != null) {
File file = File(data.images[i]!.path);
String fileName = file.path.split('/').last;
http.MultipartFile mFile = http.MultipartFile(
'images_$imgNum',
file.readAsBytes().asStream(),
await file.length(),
filename: fileName,
);
imgNum++;
request.files.add(mFile);
}
}
(data.images is a list of XFiles? , request is the http.MultipartRequest)
All the other fields and headers are working and being saved correctly.
I have tried using Dio too which gives the same response. The response from the server is :
{data: {error: Cannot read property '0' of undefined}, message: Something went wrong. Please try again later.}
Our project also has a website where the form is working correctly, and when the http request there shows the images as follows : (in Google Chrome)

The api team has also shared Swagger Ui API docs-

What am I doing wrong? How can I fix this?
Thank you for responding.
I have a REST API to callout from Salesforce.
The authorization of the API is through access token.
I am able to get the access token through POST request in Salesforce. Also tested from Postman through that token and able to get a successful response.
I am using the below code to callout the API using the access token:
String endpoint_x = '*****';//Putting my endpoint here
Http httpObject;
HttpResponse response;
String accessToken;
accessToken = MyUtilityClass.getAccessToken();
jsonBody = json.serializePretty('', true);//Yes, My JSON is empty
HttpRequest request = new HttpRequest();
request.setEndpoint(endpoint_x);
request.setHeader('Authorization', 'Bearer '+accessToken);
request.setMethod('POST');
request.setBody(jsonBody);
httpObject = new Http();
response = httpObject.send(request);
System.debug('Response=' + response);
Getting Response value as below:
System.HttpResponse[Status=Internal Server Error, StatusCode=500]
I have tried putting '{}' in the Jsonbody. Added 'Content-Type' in header but nothing worked.
Where should I lookout for this?
In the Postman, I was not putting anything in the body, and getting a successful response.
To get the same behaviour, I was using empty string in Apex, like this:
jsonBody = json.serializePretty('', true);
But the parser was not working correctly.
To solve this, I created a class without any field:
class ClassForEmptyBody{
}
And used object of that class in the serializer:
ClassForEmptyBody classForEmptyBodyObject = new ClassForEmptyBody();
jsonBody = json.serializePretty(classForEmptyBodyObject , true);
Why are you passing json body if nothing is in there. Just skip setbody code and try.
I am trying to upload a video and encode it via azure rest service.
I have now hit the step of encoding the video but I am having difficulties with the request.
The following code shows my request:
var joburl = res.RequestMessage.RequestUri + "Jobs";
client = new HttpClient();
client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Bearer " + token);
client.DefaultRequestHeaders.Add("x-ms-version", "2.8");
client.DefaultRequestHeaders.Add("DataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("MaxDataServiceVersion", "3.0");
client.DefaultRequestHeaders.Add("x-ms-date", date);
//accept
t = new NameValueHeaderValue("odata", "verbose");
type = new MediaTypeWithQualityHeaderValue("application/json");
type.Parameters.Add(t);
client.DefaultRequestHeaders.Accept.Add(type);
result = await client.PostAsync(joburl,json);
the url:https://wamsamsclus001rest-hs.cloudapp.net/api/Jobs
the json:
{"Name":"khgfiuydencodingjob","InputMediaAssets":[{"__metadata":{"Uri":"https://wamsamsclus001rest-hs.cloudapp.net/api/Assets('nb%3acid%3aUUID%3ad037b321-cd1c-43a9-9607-c4910fa7a85b')"}}],"Tasks":[{"Configuration":"H264 Adaptive Bitrate MP4 Set 720p","MediaProcessorId":"nb:mpid:UUID:1b1da727-93ae-4e46-a8a1-268828765609","TaskBody":"<?xml version=\"1.0\"encoding=\"utf-8\"?><taskBody><inputAsset>JobInputAsset(0)</inputAsset><outputAsset>JobOutputAsset(0)</outputAsset></taskBody>"}]}
The bearer token works as I use it for other request.
But I get a bad request 400 with the followin error message:
{"error":{"code":"","message":{"lang":"en-US","value":"Parsing request content failed due to: Make sure to only use property names that are defined by the type"}}}
Can anyone spot the error.
Thank you for the help
Okay I got it to work. Needed a odata=verbose in my json/string content - like this:
var jobInJson = JsonConvert.SerializeObject(job);
json = new StringContent(jobInJson, Encoding.UTF8);//,
json.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json;odata=verbose");
I tried this earlier however I got a error 500 but now it is working.
I've used the Yammer API extensively for accessing current users internal network. All API calls have been working correctly (GET's and POST's) with the original token extracted from;
"https://www.yammer.com/oauth2/access_token.json?client_id={App ID}&client_secret={App Secret}&code={Access Code}"
and using the headers; "Authorization : Bearer {Token}" and "Cookie : {Cookies Received from HTML request}.
I've gotten the tokens for all accessible networks using;
"https://www.yammer.com/api/v1/oauth/tokens.json".
Accessing external networks beyond this point has proved troublesome. I changed the header to "Authorization : Bearer {NetworkToken}". While I am able to GET details from external networks, I cannot POST to external networks. I always receive a '401 Unauthorized' response. The 'Unauthorized' requests include deleting messages and liking messages in external networks.
Is there another step between being able to read data from an external network and enabling POST methods?
If I could get any insight into this i'd be extremely grateful!
Cheers!
When accessing external networks, you need to set the authToken to the authToken for that external network.
Step 1 - Get all auth tokens:
yam.platform.request({
url: "oauth/tokens.json",
type: 'GET',
success: function (msg) {
accessTokens = msg;
/....
},
error: function (msg) {
console.log(msg);
error(msg);
}
Step 2: Set the authToken to the correct external network
var currentToken = "";
$.each(accessTokens, function (i,val) {
if (val.network_permalink == $.cookie('networkPermalink')) {
currentToken = val;
}
});
While I was working on a project last month, I used the following way to post message.
The message has to be Byte encrypted in UTF-8 format.
Specify the content type as "application/x-www-form-urlencoded".
So, an example code would be:
HttpWebRequest a = (HttpWebRequest)WebRequest.Create(postUrl);
a.Headers.Add("Authorization", "Bearer" + authToken);
a.Method = "POST";
byte[] message = Encoding.UTF8.GetBytes("body=" + message + "&replied_to_id=" + threadID);
a.ContentType = "application/x-www-form-urlencoded";
a.ContentLength = message.Length;
using (var postStream = request.GetRequestStream())
{
postStream.Write(message, 0, message.Length);
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (var postStreamForResponse = response.GetResponseStream())
{
StreamReader postReader = new StreamReader(postStreamForResponse);
string results = postReader.ReadToEnd();
postReader.Close();
}
I've discovered quite a few inconsistencies quirks with the Yammer API. I've figured out external networks in their totality now. Here are some things that may not be clear;
When doing a POST or DELETE request, do not include the network_permalink in the url! Only include the network_permalink when you're doing a GET request. This was my main issue.
Required request headers;
Content-Type : application/x-www-form-urlencoded
Accept : application/json
Cookie : _workfeed_session_id=(A code that can be extracted from the response from your first request with an auth token)
Authorization : Bearer (Access token for whichever network you wish to access)
Oh and just FYI, to request threads within the 'All Company' group this is the url; https://www.yammer.com/(network_permalink)/api/v1/messages/general.json
Thanks for the answers!
