Question

I’m trying to do a fairly basic HTTP PUT using RestKit. I don’t want to put the entire object, since the API call was designed to accept a single query parameter and just update that field. I’ve tried two approaches so far, both unsuccessful.

URL to post to: https://myserver/api/users/{userId}

Query string parameter: verificationCode=

Example usage: PUT https://myserver/api/users/101?verificationCode=646133

Approach #1: Put the query parameter in a RKParams object and make the PUT call with those params.

    NSString *putUrl = [NSString stringWithFormat:@"/api/users/%i", [APIUserInfo sharedAPIUserInfo].apiUserIdx];
    NSLog(@"the PUT url is %@", putUrl);

    // Send a PUT to a remote resource. The dictionary will be transparently
    // converted into a URL encoded representation and sent along as the request body
    NSDictionary* paramsDict = [NSDictionary dictionaryWithObject:[_verificationCode text] forKey:@"verificationCode"];
    // Convert the NS Dictionary into Params
    RKParams *params = [RKParams paramsWithDictionary:paramsDict];

    [[RKClient sharedClient] put:putUrl params:params delegate:self];

Approach #2: Build the entire url and try a PUT with params set to nil.

    NSString *putUrl = [NSString stringWithFormat:@"/api/users/%i?verificationCode=%@", [APIUserInfo sharedAPIUserInfo].apiUserIdx, [_verificationCode text]];
    NSLog(@"the PUT url is %@", putUrl);

    [[RKClient sharedClient] put:putUrl params:nil delegate:self];

Neither approach is working for me. The first fails saying “RestKit was asked to retransmit a new body stream for a request. Possible connection error or authentication challenge?” then runs for about 10 seconds and times out. The second approach fails saying HTTP Status 405 – Method Not Allowed.

Can anyone point out where I’m going wrong, or provide me with a simple PUT example using RestKit? Most of the examples I’ve found at there are putting the entire object which I don’t want to do in this case.

UPDATE:

Approach #2 worked well once I got a few things sorted out on the server side. Final solution:

NSString *putUrl = [NSString stringWithFormat:@"/api/users/verify/%i?verificationCode=%@", [APIUserInfo sharedAPIUserInfo].apiUserIdx, [_verificationCode text]];
NSLog(@"the PUT url is %@", putUrl);

[[RKClient sharedClient] put:putUrl params:nil delegate:self];

Answer 1

the HTTP PUT method is disabled on your webserver. It is by default on all webserver for security reasons.

HTTP Status 405 - Method Not Allowed.
