问题
I am consuming REST APIs, one of the api is PATCH
, i tried to invoke it using following code but it throws error, while same api works in Postman
client.
+ (NSURLSessionTask *)callPATCHAPIWithAPIName:(NSString *)apiName andCompletionHandler:(void(^)(id result, NSInteger responseCode, NSError *error))completionHandler
{
NSString *getURL = @"192.168.1.100/UpdateDeviceInfo/iPhone6/OS 9.2";
NSURL *URL = [NSURL URLWithString:getURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:URL];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.timeoutIntervalForRequest = 45.0f;
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
// Create Data from request
NSData *requestData = [NSData dataWithBytes: [@"" UTF8String] length:[@"" length]];
[request setHTTPMethod:@"PATCH"];
[request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)[requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:requestData];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request
completionHandler:
^(NSData *data, NSURLResponse *response, NSError *error)
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
NSInteger responseCode = [httpResponse statusCode];
NSLog(@"response Code : %ld",(long)responseCode);
}];
[task resume];
return task;
}
[Error :Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x14e86d490 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}}]
I am passing parameters in query string, not in request body. Though same thing is working in Postman
client & Android.
回答1:
It seems like you have a whitespace in NSString *getURL = @"192.168.1.100/UpdateDeviceInfo/iPhone6/OS 9.2"
I do not believe whitespaces are supported in url formats! Instead, if whitespaces are necessary, make sure you use getURL = [getURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
in order to handle whitespaces in url strings!
