GET请求，iOS [英] GET request, iOS

问题描述

我需要做这个GET请求：

I need to do this GET request:

http://api.testmy.co.il/api/sync?BID=1049&ClientCode=3847&Discount=2.34&Service=0&Items=[{"Name":"Tax","Price":"2.11","Quantity":"1","SerialID":"1","Remarks":"","Toppings":""}]&Payments=[]

在浏览器中，我收到了以下回复：

In browser I get this response:

{
    "Success": true,
    "Atava": [],
    "Pending": [],
    "CallWaiter": false
}

但是在iOS中它不起作用。

But in iOS its not working.

我尝试：

I try:

NSString *requestedURL=[NSString stringWithFormat:@"http://api.testmy.co.il/api/sync?BID=%i&ClientCode=%i&Discount=2.34&Service=0&Items=[{\"Name\":\"Tax\",\"Price\":\"2.11\",\"Quantity\":\"1\",\"SerialID\":\"1\",\"Remarks\":\"\",\"Toppings\":\"\"}]&Payments=[]",BID,num];
NSURL *url = [NSURL URLWithString:requestedURL];
NSURLResponse *response;
NSData *GETReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSString *theReply = [[NSString alloc] initWithBytes:[GETReply bytes] length:[GETReply length] encoding: NSASCIIStringEncoding];
NSLog(@"Reply: %@", theReply);

OR

NSString *requestedURL = [NSString stringWithFormat:@"http://api.testmy.co.il/api/sync?BID=%i&ClientCode=%i&Discount=2.34&Service=0&Items=[{'Name':'Tax','Price':'2.11','Quantity':'1','SerialID':'1','Remarks':'','Toppings':''}]&Payments=[]", BID, num];

OR

NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
[params setObject:@"Tax" forKey:@"Name"];
[params setObject:@"2.11" forKey:@"Price"];
[params setObject:@"1" forKey:@"Quantity"];
[params setObject:@"1" forKey:@"SerialID"];
[params setObject:@"" forKey:@"Remarks"];
[params setObject:@"" forKey:@"Toppings"];

NSData *jsonData = nil;
NSString *jsonString = nil;

if([NSJSONSerialization isValidJSONObject:params])
{
    jsonData = [NSJSONSerialization dataWithJSONObject:params options:0 error:nil];
    jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSLog(@"%@", jsonString);
}

NSString *get = [NSString stringWithFormat:@"&Items=%@", jsonString];

NSData *getData = [get dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"GET"];
[request setTimeoutInterval:8];
[request setHTTPBody:getData];
[request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];

我尝试了所有上面的代码，但它不起作用（很长一段时间..只是停留在这个）。
如何解决这个问题？

I tried all above code but it doesn't work(long time out.. just stuck on this).
How to fixing this?

推荐答案

这是因为你的URL不正确，这个字符串应该加上百分号转义。试试这个：

This is because your URL is not correct, this string should add percent escape. Try with this:

NSString *requestedURL=[NSString stringWithFormat:@"http://api.testmy.co.il/api/sync?BID=%i&ClientCode=%i&Discount=2.34&Service=0&Items=[{'Name':'Tax','Price':'2.11','Quantity':'1','SerialID':'1','Remarks':'','Toppings':''}]&Payments=[]",BID,num];
NSURL *url = [NSURL URLWithString:[requestedURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//and you use this url
