Iphone 如何使用HTTPHeaderField创建NSURLRequest

我有如下要求

curl-H'授权：OAuth OAuth_signature_method=“明文”，OAuth_consumer_key=“de4422f-f3ff-4929-bb65-eadc6f5218e2”，OAuth_token=“85ab49a-9081-4641-812c-09d3130e3a8”，OAuth_signature=“0723ba36-8d19-4fab-9337-7e81004655c%2685E3879B-0b57-481b-a8fc-8eb1426fc72”' 'https://external.ningapis.com/xn/rest/ippinn/1.0/User/?author=0n1s8aln92xhx&fields=iconUrl，电子邮件，url，全名，出生日期，性别'

我想使用NSURLRequest创建相同的请求 我试过了，在论坛上搜索得到了很多解决方案，但没有成功

我做了以下代码

NSURL *url = [NSURL URLWithString:@"https://external.ningapis.com/xn/rest/ippinn/1.0/User/?author=0n1s8aln92xhr&fields=iconUrl,email,url,fullName,birthdate,gender"];  
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

[request setHTTPMethod:@"POST"];

NSString  *authorization = @"OAuth ";
authorization  = [authorization stringByAppendingFormat:@"oauth_signature_method=%@",@"PLAINTEXT"];
authorization  = [authorization stringByAppendingFormat:@"&oauth_consumer_key=%@",@"de4422f-f3ff-4929-bb65-eadc6f5218e2"];
authorization  = [authorization stringByAppendingFormat:@"&oauth_token=%@",@"85ab49a-9081-4641-812c-09d3130e3a8"];
authorization  = [authorization stringByAppendingFormat:@"&oauth_signature=%@",@"0723ba36-8d19-4fab-9337-7e81004655c%26e385879b-0b57-481b-a8fc-8eb1426fc72"];

NSLog(@"authorization =>%@",authorization);
[request setValue: authorization forHTTPHeaderField: @"Authorization"];

 self.connection = [NSURLConnection connectionWithRequest:request delegate:self];
if (_connection) {
    self.receivedData = [[NSMutableData data] retain];
}

---

请告诉我哪里出了问题

Hi@Teodor谢谢你的回答。我试过了，但仍然从服务器得到的响应是“code=1；reason=”未收到必需的参数。这些参数必须存在。oauth_signature_method；status=400；subcode=9；success=0；trace=“8a5d4a32-256c-4c0b-9e0d-54e9a05cebc7”}“可能的原因是什么。查看服务器端，查看服务需要从您的请求中获取的参数列表。必须有强制参数和可选参数（取决于它们的设置方式）。确保您在请求中发送了所有必需的参数。我遇到了观察。如果我用“GET”http方法发送，我们就会得到数据。谢谢你的回答。

    NSURL *url = [NSURL URLWithString:@"https://external.ningapis.com/xn/rest/ippinn/1.0/User/?author=0n1s8aln92xhr&fields=iconUrl,email,url,fullName,birthdate,gender"];  
    NSString  *authorization = @"OAuth ";
    authorization  = [authorization stringByAppendingFormat:@"oauth_signature_method=%@",@"PLAINTEXT"];
    authorization  = [authorization stringByAppendingFormat:@"&oauth_consumer_key=%@",@"de4422f-f3ff-4929-bb65-eadc6f5218e2"];
    authorization  = [authorization stringByAppendingFormat:@"&oauth_token=%@",@"85ab49a-9081-4641-812c-09d3130e3a8"];
    authorization  = [authorization stringByAppendingFormat:@"&oauth_signature=%@",@"0723ba36-8d19-4fab-9337-7e81004655c%26e385879b-0b57-481b-a8fc-8eb1426fc72"];
    NSData *postData = [authorization dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
    NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
    [urlRequest setURL:url];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [urlRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [urlRequest setValue:@"utf-8" forHTTPHeaderField:@"charset"];
    [urlRequest setHTTPBody:postData];
    [urlRequest setTimeoutInterval:60.0];

    NSURLConnection *tmpConn = [[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self] autorelease];
    self.connection = tmpConn;//I suppose "connection" is a retained property 
    if (_connection) {
        self.receivedData = [[NSMutableData data] retain];
    }
