我正在尝试向我的 Ruby on Rails 本地服务器发送 POST 请求。不幸的是,起初由于protect_from_forgery,它不会让我POST,所以我最终在开发和生产中将它设置为false。基本上,我的问题是我将从我的 Cocoa 应用程序发送带有所有需要的参数的 POST 请求,并且 Ruby 服务器会看到它。但是,每当服务器插入我的请求时,所有 VALUES 都设置为 NULL,但 created_at 和 updated_at 除外。我不知道 Ruby on Rails 是如何工作的(因为我使用了脚手架),所以我不确定我需要在哪里设置参数以便正确插入它们。
谢谢!
可可代码:
NSString *urlString = @"http://localhost:3000/clients";
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL: url];
[req setHTTPMethod: @"POST"];
NSData *putParams = [@"name=TEST&ip_address=1.1.1.1" dataUsingEncoding:NSUTF8StringEncoding];
[req setHTTPBody: putParams];
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
NSData *responseData = [NSURLConnection sendSynchronousRequest:req returningResponse:&urlResponse error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300)
NSLog(@"Response: %@", result);
[url release];
[req release];
[error release];
服务器响应:

我尝试在客户端控制器中执行此操作,但问题仍然存在:
if params[:name].present?
@client = Client.new(:name => params[:names])
else
@client = Client.new(params[:client])
end
以防万一需要(完整的客户端控制器-所有这些都带有脚手架):
class ClientsController < ApplicationController
# GET /clients
# GET /clients.xml
def index
@clients = Client.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @clients }
end
end
# GET /clients/1
# GET /clients/1.xml
def show
@client = Client.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @client }
end
end
# GET /clients/new
# GET /clients/new.xml
def new
@client = Client.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @client }
end
end
# GET /clients/1/edit
def edit
@client = Client.find(params[:id])
end
# POST /clients
# POST /clients.xml
def create
if params[:name].present?
@client = Client.new(:name => params[:names])
else
@client = Client.new(params[:client])
end
respond_to do |format|
if @client.save
format.html { redirect_to(@client, :notice => 'Client was successfully created.') }
format.xml { render :xml => @client, :status => :created, :location => @client }
else
format.html { render :action => "new" }
format.xml { render :xml => @client.errors, :status => :unprocessable_entity }
end
end
end
# PUT /clients/1
# PUT /clients/1.xml
def update
@client = Client.find(params[:id])
respond_to do |format|
if @client.update_attributes(params[:client])
format.html { redirect_to(@client, :notice => 'Client was successfully updated.') }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @client.errors, :status => :unprocessable_entity }
end
end
end
# DELETE /clients/1
# DELETE /clients/1.xml
def destroy
@client = Client.find(params[:id])
@client.destroy
respond_to do |format|
format.html { redirect_to(clients_url) }
format.xml { head :ok }
end
end
end
PS如果我的问题不清楚,请告诉我。
