[英]How to add URL parameters to JSON web service call - Objective C
我正在嘗試使用SBJsonParser API使用以下代碼從JSON Web服務中獲取信息:
SBJsonParser *parser = [[SBJsonParser alloc] init];
// Prepare URL request to download statuses from Twitter
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://twitter.com/statuses/public_timeline.json"]];
// Perform request and get JSON back as a NSData object
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
// Get JSON as a NSString from NSData response
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
但是我需要在Web服務URL中添加兩個參數(用戶和密碼)及其值,因此URL將為“ http://twitter.com/statuses/public_timeline.json?user=name&password=test”。 我已經搜索了有關API的信息,但是沒有成功。
非常感謝您的幫助。
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://twitter.com/statuses/public_timeline.json?user=%@&password=%@", @"name", @"test"]]];
根據需要用自己的變量替換@"name"
和@"test"
。
我假設您有變量中的值,對嗎? 如果是這樣,只需使用NSString的stringWithFormat:方法。
更換:
@"http://twitter.com/statuses/public_timeline.json"
帶有:
[NSString stringWithFormat:@"http://twitter.com/statuses/public_timeline.json?user=%@&password=%@", user, password]
NSString *user = @"user";
NSString *password = @"password";
NSString *urlStr = [NSString stringWithFormat:@"http://twitter.com/statuses/public_timeline.json?user=%@&password=%@", user, password];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: urlStr]];
您也可以這樣做。
NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc] initWithURL:@"http://twitter.com/statuses/public_timeline.json"];
[theRequest setHTTPMethod:"@POST"] // Or get, push, put
NSString theRquest_Body = [NSString stringWithFormat:@"?user=%@&password=%@",
[user stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[password stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]],
[theRequest setHTTPBody:[theRequest_body dataUsingEncoding:NSUTF8StringEncoding]];
