my request

url="http://algumip:algumaporta/dowPDFNF?cChave="+chave

 $.ajax({
    url: url,
    dataType: 'jsonp',
    success: function (data) {
        console.log(JSON.stringify(data));
    },
    type: 'POST'
});

error that returns:

Uncaught SyntaxError: Unexpected token :

However, when I pass the url (generated by the variable url) directly on the server, I get the right return. See image the return: inserir a descrição da imagem aqui

What I need is to get this return to have the pdf download

{"pdf":"http:\\\\algumip\\download\\6a423e04e2c2dfd4a59f0001ec8bbf44b9a6a6d-nfe.pdf"}

  • I believe that is not the case, because I can reach the other domain, problem is in reading the return "date" in Success

  • The problem should be this JSON.stringify, gives a console.log to see how the date is coming.

  • Places a Debugger inside the Success function. Success: Function (data) { Debugger console.log(JSON.stringify(data); } To see if you are logging into Success.

  • @Daniellearrudatorres Fact, change the title because in this case there is no relationship with CORS and the fact that the requirement is for another domain.

  • @Daniellearrudatorres you cannot do a jsonp post for another domain, the request cannot be get?

  • @Mayconf.Castro the Debugger returns me "Uncaught Syntaxerror: Unexpected Identifier"

  • @Leandroangelo I’ll switch to Get and test

  • Does not inform which callback.

  • The return treatment is also different, implement jsonpCallback to analyze the return.

  • Even with jsonp: "jsonpcallback", dataType: "jsonp". I still have the error return : Uncaught Syntaxerror: Unexpected token :

  • Let’s go continue this discussion in chat.

Try to add the item async: false, because according to the documentation, requests for jsonp remote servers do not work if the mode asynchronous is active.

Cross-Domain requests and dataType: "jsonp" requests do not support synchronous Operation. 

$.ajax({ 
    async: false, 
    method: 'GET', 
    url: url, 
    contentType: "application/json", 
    jsonpCallback: minhafuncaocallback, 
    dataType: 'jsonp', 
    success: function (json) { 
        console.log(json); 
    }, 
    error: function (jqXHR, textStatus, errorThrown) { 
        console.log("AJAX ERRO" + jqXHR + textStatus + errorThrown); 
    } 
});

It is good that this request is made after the page has been fully loaded because a request synchronous prevents page loading from continuing until the response is received from that request which may decrease the quality of the user experience on your site, if applicable.
