Question

我已经使用POST方法在我的应用程序中使用标题值和params来调用API。但在我的后端无法获得我的标头值进行身份验证。即使我的回复也有无效的用户。我附上了我的片段。你能不能帮我解决这个问题。

NSString *post = [NSString stringWithFormat:@"test=Message"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

[request setURL:[NSURL URLWithString:@"http://myURL.com/FakeURL"]];
[request setHTTPMethod:@"POST"];

NSString *authStr=[NSString stringWithFormat:@"userName:xxx"];
NSData *authData=[authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *headerValue=[NSString stringWithFormat:@"Basic %@",[authData base64EncodedStringWithOptions:0]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setValue:headerValue forHTTPHeaderField:@"Authorization"];


NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
NSLog(@"requestReply: %@", requestReply);

为授权，网址和内容长度创建单个网址请求：

您在Request HeaderField中缺少内容长度。

 - (void)postRequest

 {
   NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
    NSString *post = [NSString stringWithFormat:@"test=Message"];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

    [request setURL:[NSURL URLWithString:@"http://myURL.com/FakeURL"]];
    [request setHTTPMethod:@"POST"];

    NSString *authStr=[NSString stringWithFormat:@"userName:xxx"];
    NSData *authData=[authStr dataUsingEncoding:NSUTF8StringEncoding];
    NSString *headerValue=[NSString stringWithFormat:@"Basic %@",[authData base64EncodedStringWithOptions:0]];

    [request setValue:headerValue forHTTPHeaderField:@"Authorization"];

    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];


    NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
        NSLog(@"requestReply: %@", requestReply);
    }];
    [task resume];
}

确保您已添加NSURLSessionDataTask以继续。
另请检查您是否在info.Plist中启用了应用传输安全性。

这有助于解决您的问题。

编辑：

尝试这样做：

 if(data!= nil)
        {
            id JSON = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
            NSLog(@"Response === %@",JSON);
        }

而不是：

NSString * requestReply = [[NSString alloc] initWithData：data encoding：NSASCIIStringEncoding];

Objective C - 带有header和params的HTTP POST REQUEST句柄
