    This Freelance is very smart and capable. But beware! He is a blatant liar! Before explaining I have skype screenshots to prove (he will fabricate new stories like usual) He made the bot, but originally promised he would fix bugs and small issues-he said he would be available for upkeep, the moment he was payed HE WAS GONE! no replies for a few weeks, then he wakes up and says he will do, the gone again! He had the audacity to bid again on the same project, when I posted it again for someone to fix what He promised he would do. Punchline-He's not trustworthy at all!

    Project Description:Preciso atualizar um sistema de API para nova versão que atualiza preços e produtos em meu website.
    SigmaVisual has not completed any projects.
  • $144 USD In Progress

    Hello,I need someone who have experience with scraping data from web service/API help me with this work. If you are student, do not apply. I need professional people who have experience with python scraping that can finish it for me. Knowledge of visualization will helpful for bonus. Here is the job. We have a website with web service call like a survey interview, depend on the previous question, it will display the next question. So I need to get all the content of the survey.The first request to the server is something like:http://localhost/?s=Start&description=DES1&value=VAL1&units=UNIT&description=DES2&value=VAL2&description=DES3&value=VAL3It will create a session variable for current session to use in the 2nd request as well as return the first content (next question). Then there will be a series of questions for this above session with value Yes, No, Back (first question don"t have Back) call with the URL like below:http://localhost/?m=NAME&session=530cc4c3000082aafmd&navigationMethod=[Yes, No, Back]Each time we click Yes/No/Back button, the navigationMethod variable will change accordingly and return a json content for the next question:{"variable":{"variable1": "value1","variable2": "value2","variable3": "value3","variable4": "value4","variable5": "value5","variable6": "value6","variable7": "value7"}}At the end, there will be no question, just a json return with a lot of information. But now, the session variable is killed so we can not get back to previous question.What I need you to do is to write a python script that can help me to scrap all the data and save to a text file. What I think we need to do is write a breadth-first search or depth-first search function to traverse along the tree that can save each state when we click the button. The state will include both the hierarchy of current node (like ... [1 for Yes, 2 for No]) as well as the content (json returnted). And then when the session variable no longer work, we will need to create a new session variable and get the previous state we have saved and continue, continue until we traverse all the leaves of tree.Below is requirements:+ It should be a function that I can call from command line like:CMD >>>> python -DES1 -VAL1 -UNIT1 -DES2 -VAL2 -DES3 -VAL3 -output.txt+ The content of text file should have some way that allow me to track the hierachy of questions, which one display first, which one is second, which one is the child of which one. [Because it limit to 4000 character, I put the sample in text file.]The deep of each tree may be up to 50 levels, even more than that. Bonus 1: If you can have some way that allow me to filter the content it return, like I only want to save variable3, variable5, variable6 from the json return to text file. There is a bonus for it.Bonus 2: If you can format the data and write a tool allow me to import the text file output.txt and display it like a tree diagram like this example , whenever I click to one note, i can get the data popup, that would be great. There is an extra bonus.Bonus 3: If you can write a tree diagram allow me to load the text file output.txt and make change, and save it back to the original file. There is also another extra bonus.Let me know with your price:Basic: XX$Bonus 1: XX$Bonus 2: XX$Bonus 3: XX$

    2 Things.1. Create a client portal in my wordpress site.2. Integrate an api into the client portal.The thought process: A company goes to my site and has the ability to run several reports for free using the api. The key for me is to get them to sign in so I can retain their email address and they can save/download the data from the api. On one page, I would like there to be a button that says "enter domain name" and the api will connect with the third party software and have the data flash on my web page (in a report format). They can then choose to login and save the report or download a pdf version of it.Hopefully this made sense.

Ideally the function will get the match code (you can see it in URL after /match/[match-code]/) as a parameter and the interval in seconds to update, and return an array with all the real time statistics mentioned above. The parsing should not take more than 5 seconds.

    **Willing to pay monthly for success and software updatesWe are looking for software to assist in the pulling and purchasing of tickets on We need software that will monitor the on sale web page and at the instant the ticket on sale opens up the software will navigate it"s way through the on screen dialogs, solve the captcha, and pull the tickets, then give the user the option of purchasing the tickets. The captcha needs to be solved at a very high success rate. The higher the success rate, the more we are willing to pay for this. The other requirement is to be able to queue up a number of these processes simultaneously, so they will all be pulling tickets instantaneously after a ticketmaster sale opens up. Within seconds after the sale opens up we would like to be prompted with numerous ticket choices for purchase. We would also like to be able to set the program in "spinner" mode where it constantly polls an event for tickets that meet certain specifications and if it finds any suitable tickets it automatically purchases them for us.The winning bidder for this project will most likely already be very familiar with the ticketmaster web site and will have a lot of experience in this type of programming and be very familiar with what our requirements are. If you are already working on something similar to this, seeing your product in action will help you to win the bid.
