使用NSString发送NSURLSession作为post方法的主体
使用NSString发送NSURLSession作为post方法的主体
提问于 2015-02-04 23:53:44
我试图使用下面的示例将字符串发送到服务器：
// 1
NSURL *url = [NSURL URLWithString:@"YOUR_WEBSERVICE_URL"];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = @"POST";
// 3
NSDictionary *dictionary = @{@"key1": @"value1"};
NSError *error = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary
options:kNilOptions error:&error];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:data completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
}区别在于我没有一个NSDictionary，而是一个存储字典数组的NSString对象，而且我发布的字符串也不能被编码--它必须是一个简单的字符串，所以如果手动输入它，它在搜索字段中是可见的。
我的NSString示例：
[{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
},
{
"api_id" = debugger;
at = "2015-02-05T01:41:13Z";
oS = IOS;
ver = "8.10";
what = "showAdAt: forViewController:";
}
]事先谢谢你，对我耐心点，因为这是我第一次尝试。我在想，如果我首先以字典作为对象将NSString转换为NSArray，那么上面的示例应该适用于我。
更新：
目前，我正在尝试将字符串发布为：
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{
@"Authorization" : @"CUSTOM AUTHORIZATION THAT I AM USING",
@"Content-Type" : @"application/json"
};
// Create the session
// We can use the delegate to track upload progress
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:@"MY WEBSITE LINK"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
//Convert the string to NSData
bodyContainerString = @"[{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:09:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"},{\"api_id\":\"A124\",\"at\":\"2011-04-10T20:10:31Z\",\"os\":\"ANDROID\",\"ver\":\"2.1\",\"what\":\"TEST\",\"value\":\"\"}]";
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
jsonData = [jsonData subdataWithRange:NSMakeRange(0, [jsonData length] - 1)];
NSString* newStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSLog(newStr);
request.HTTPBody = jsonData;
NSURLSessionDataTask *uploadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Process the response
NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
if (!error && httpResp.statusCode == 201) {
//if no error on upload then delete content of plist
NSLog(@"Success on post1");
}
NSLog(@"Success on post2");
}];
[uploadTask resume];更新2，生成的链接应该如下所示：
curl -X POST http://MY_LINK/smtg -H 'Authorization: CUSTOM_FIRST_HEADER' -H "Content-Type: application/json" -d '[{"api_id":"A124","at":"2011-04-10T20:09:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""},{"api_id":"A124","at":"2011-04-10T20:10:31Z","os":"ANDROID","ver":"2.1","what":"TEST","value":""}]'回答 1

最后，我使用了我在这里找到的第一个示例--我的实现：
NSURL *url = [NSURL URLWithString:@"MY_LINK/smtg"];
//Create thhe session with custom configuration
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{
@"Authorization" : [NSString stringWithFormat:@"BEARER %@",finalToken],
@"Content-Type" : @"application/json"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
// 2
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = @"POST";
// 3
NSError *error = nil;
NSData* jsonData = [bodyContainerString dataUsingEncoding:NSUTF8StringEncoding];
if (!error) {
// 4
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
fromData:jsonData completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
// Handle response here
}];
// 5
[uploadTask resume];
