iOS设备可以将PUT请求发送到Rails应用程序吗? [英] Can iOS devices send PUT requests to Rails apps?
问题描述
我们已经尝试了无数次将更新的PUT请求发送到我们的Rails服务器,并且不断收到404您要查找的页面不存在"
We've tried numerous times sending update PUT requests to our Rails server and we keep receiving a 404 "The page you were looking for does not exist"
我们的更新方法非常简单(实际上是通用轨道).
Our update method is very simple (practically generic rails).
def update
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
结束
当我从命令行运行CURL以测试更新方法时,它工作正常.但是,当我在Objective-c中尝试相同的方法时,总是会导致404错误.
When I run CURL from the command line to test the update method, it works fine. But, when I try the same methods in objective-c, it always results in a 404 error.
所以我的问题是:iOS设备可以使用NSURLConnection将PUT请求发送到服务器吗?
So my question is: can iOS devices send PUT requests to servers using NSURLConnection or is this not implemented?
更新::
这不会更新数据库
NSString *dataString = @"user[first_name]=bob";
NSData *postBodyData = [NSData dataWithBytes: [dataString UTF8String] length:[dataString length]];
NSString *urlString = [NSString stringWithFormat:@"example.com/users/1.json"];
NSURL *fullURL = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:fullURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20];
[request setHTTPMethod: @"PUT"];
[request setHTTPBody:postBodyData];
self.todoConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
receivedData = [NSMutableData data];
这将更新数据库
NSString *urlString = [NSString stringWithFormat:@"example.com/users/1.json?user[first_name]=bob"];
NSURL *fullURL = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:fullURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20];
[request setHTTPMethod: @"PUT"];
self.todoConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
receivedData = [NSMutableData data];
推荐答案
您可以创建NSMutableURLRequest并设置HTTP方法:
You can make an NSMutableURLRequest and set the HTTP method:
- (void)setHTTPMethod:(NSString *)method
提供字符串@"PUT"
.
在这里,您可以根据此类请求创建NSURLConnection.
Here is how you can create an NSURLConnection from such a request.
NSMutableURLRequest *myMutableRequest[[NSMutableURLRequest alloc] initWithURL:myURL];
[myMutableRequest setHTTPMethod:@"PUT"];
[NSURLConnection connectionWithRequest:myMutableRequest delegate:myDelegate];
