curl with Path Variables and Query Param Variables

See more CURL Examples

This example demonstrates using variables located in the path and query params with the {{variable_name}} syntax. Objective-C

#import <NSString.h>
#import <CkoHttpCurl.h>
#import <CkoJsonObject.h>

BOOL success = NO;

// Variables can occur in the path and query params.  
// Variable names are enclosed between {{ and }}

//  curl -X GET https://httpbin.org/{{verb}}?id={id_value}}
NSString *targetCurl = @"curl -X GET https://httpbin.org/{{verb}}?id={{id_value}}";

CkoHttpCurl *httpCurl = [[CkoHttpCurl alloc] init];

// Provide values for variables.
// In this example, "verb" is a path variable, and "id_value" is a query param variable.
[httpCurl SetVar: @"verb" varValue: @"get"];
[httpCurl SetVar: @"id_value" varValue: @"123"];

// Run the curl command.
success = [httpCurl DoYourThing: targetCurl];
if (success == NO) {
    NSLog(@"%@",httpCurl.LastErrorText);
    return;
}

CkoJsonObject *responseJson = [[CkoJsonObject alloc] init];
responseJson.EmitCompact = NO;

int statusCode = [httpCurl.StatusCode intValue];
NSLog(@"%@%d",@"response status code: ",statusCode);

[httpCurl GetResponseJson: responseJson];
NSLog(@"%@",[responseJson Emit]);

// Output:

// response status code: 200
// {
//   "args": {
//     "id": "123"
//   },
//   "headers": {
//     "Host": "httpbin.org",
//     "X-Amzn-Trace-Id": "Root=1-69e92914-5d4136d240f2f7fe1056f126"
//   },
//   "origin": "222.222.222.222",
//   "url": "https://httpbin.org/get?id=123"
