C#,Java & Ruby Code Samples to Create PDF File from HTML

Question

This tutorial shows how developers can create PDF file from HTML in Cloud using Aspose.Pdf for Cloud API in their applications. You can use this REST API with any language: .NET, Java, PHP, Ruby, Rails, Python, jQuery and many more.

[C# Code Sample]

stringstrURI = "http://api.aspose.com/v1.1/pdf/outPdfFile.pdf?templateFile=input.html&templateType=html";

stringsignedURI = Sign(strURI);

StreamReader reader = new StreamReader(ProcessCommand(signedURI, "PUT"));

//further process JSON response

stringstrJSON = reader.ReadToEnd();

//Parse the json string to JObject

JObjectparsedJSON = JObject.Parse(strJSON);

BaseResponse stream = JsonConvert.DeserializeObject<BaseResponse>(parsedJSON.ToString());

if (stream.Code == "200" &&stream.Status == "OK")

Console.WriteLine("Empty PDF file has been created successfully");

 

//Here is the BaseResponse class

public class BaseResponse

{

publicBaseResponse() { }

        public string Code { get; set; }

        public string Status { get; set; }

}

 

 

[Java Code Sample]

 

 

//build uri to create empty pdf

    String strURI = "http://api.aspose.com/v1.1/pdf/outPdfFile.pdf?templateFile=input.html&templateType=html";

    String signedURI = Sign(strURI);

InputStreamresponseStream = ProcessCommand(signedURI, "PUT");

    String strJSON = StreamToString(responseStream);

Gsongson = new Gson();

    //Parse the json string to JObject and Deserializes the JSON to a object.

BaseResponsebaseResponse = gson.fromJson(strJSON,BaseResponse.class);

if (baseResponse.getCode().equals("200") &&baseResponse.getStatus().equals("OK"))

System.out.println("Empty PDF file has been created successfully");

 

//Here is the BaseResponse class

public class BaseResponse {

        publicBaseResponse() { }

        private String Code;

        private String Status;

        public String getCode(){return Code;}

        public String getStatus(){return Status;}

        public void  setCode(String temCode){ Code=temCode;}

        public void setStatus(String temStatus){ Status=temStatus;}

}

 

 

[Ruby Code Sample]

 

 

app_sid = '77******-1***-4***-a***-8***********'

app_key = '89******************************'

Aspose::Cloud::Common::AsposeApp.new(app_sid, app_key)

 

#build URI to create PDF from HTML

str_uri = 'http://api.aspose.com/v1.1/pdf/outPdfFile.pdf?templateFile=HtmlExample1.html&templateType=html'

 

#sign URI

signed_uri = Aspose::Cloud::Common::Utils.sign(str_uri)

RestClient.put(signed_uri, '', {:accept=>'application/json'})

 

#build URI to download output file

str_uri = 'http://api.aspose.com/v1.1/storage/file/outPdfFile.pdf'

 

#sign URI

signed_uri = Aspose::Cloud::Common::Utils.sign(str_uri)

response_stream = RestClient.get(signed_uri, :accept => 'application/json')

Aspose::Cloud::Common::Utils.save_file(response_stream, "outPdfFile.pdf")

p 'done'
