Avoid Proxy page for Print Task, Print Template; Geometry Service

PitersonPaulgek

Hi there,

Is it possible to avoid using proxy page when

1) create pdf file with Print Task, Print Template?

2) use Geometry Service for Buffer

Any help would be appreciated.

esriConfig.defaults.geometryService = new GeometryService("some URL");

esriConfig.defaults.io.proxyUrl = "/proxy/"; - HERE WE MUST PUT CORRECT ADDRESS

esriConfig.defaults.io.alwaysUseProxy = false;

Similar with me.

I am trying to avoid the proxy (more later) all works fine, apart from printing in IE11 when I get the "If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers." - even through I do push the site that I am making a request to,

The reason why I'm switching proxy off, apart from performance, is that I just can't get my head around the config for testing, we now are using a proper version control in Visual Studio so I have to test using VS, and the "localhost" seems to fail, even when I change the config.

Although I'm going to look at why that is later, if I can move away totally it would be great.

Any ideas why just IE11 is having issues?

Robert,

I commented out

esriConfig.defaults.io.proxyUrl = "/proxy/"; - HERE WE MUST PUT CORRECT ADDRESS

esriConfig.defaults.io.alwaysUseProxy = false;

and now have an error

esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.
EsriVisualisation.js:576 Something broke: Error: esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.

Piterson,

It sounds like you just need to configure your proxy url properly or just comment out those lines

esriConfig.defaults.io.proxyUrl = "/proxy/"; - HERE WE MUST PUT CORRECT ADDRESS

esriConfig.defaults.io.alwaysUseProxy = false;

The proxy should only be used when the text limit for the url params has been exceeded or you have that specific url setup in your proxy.config.

Thanks for reply, Robert.

How I configure PrintTask not to use proxy?

We have an error

init.js:140 GET http://localhost:55549/proxy/?https://user.domain.com/arcgis/rest/services/DownloadWebMap/GPServer/Export%20Web%20Map?f=json 404 (Not Found)

when run the JavaScript

app.printUrl = "some URL";
var printInfo = esriRequest({
"url": app.printUrl,
"content": { "f": "json" }
});

printInfo.then(handlePrintInfo, handleError);

function handlePrintInfo(resp) {
var layoutTemplate, templateNames, mapOnlyIndex, templates;

layoutTemplate = arrayUtils.filter(resp.parameters, function (param, idx) {
return param.name === "Template123";
});

if (layoutTemplate.length === 0) {
console.log("print service parameters name for templates must be \"Template123\"");
return;
}
templateNames = layoutTemplate[0].choiceList;

// remove the MAP_ONLY template then add it to the end of the list of templates
mapOnlyIndex = arrayUtils.indexOf(templateNames, "MAP_ONLY");
if (mapOnlyIndex > -1) {
var mapOnly = templateNames.splice(mapOnlyIndex, mapOnlyIndex + 1)[0];
templateNames.push(mapOnly);
}

// create a print template for each choice
templates = arrayUtils.map(templateNames, function (ch) {
var plate = new PrintTemplate();
plate.layout = plate.label = ch;
plate.format = "PDF";
plate.layoutOptions = {
"authorText": "Made by: ZZZ",
"copyrightText": "<copyright info here>",
"legendLayers": [],
"titleText": "<Test Title Here>",
"scalebarUnit": "Miles"
};
return plate;
});

// create the print dijit
app.printer = new Print({
"map": app.map,
"templates": templates,
url: app.printUrl
}, dom.byId("print_button"));
app.printer.startup();
}
function handleError(err) {
console.log("Something broke: ", err);
}

How I configure PrintTask not to use proxy?

Pieterson,

Any particular reason why? You do not have to use a proxy when using the PrintTask but the use the proxy will be necessary when buffering a complex polygon as the text limit for url params will likely be exceeded and the use of a put request will need to be made.
