ios - HTTP 状态 500 - 请求处理失败

Question

我试图将字符串值发布到 Sql Server。像这样

NSString *post =[NSString stringWithFormat:@"?&name=%@&password=%@&pin=%@&email=%@&phone=%@&address=%@&city=%@&status=%@",
                     name, password ,pin ,email ,phone,address,city,status];
    NSLog(@"post%@",post);
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;

    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://202.65.154.108:8080/SaveDollar/rest/deals/add"]]];

    NSLog(@"getData%@",request);

    [request setHTTPMethod:@"POST"];

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

    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];

    [request setHTTPBody:postData];

    NSLog(@"getData%@",request);


    con3 = [[NSURLConnection alloc]initWithRequest:request delegate:self];

    if(con3)
    {      webData3=[NSMutableData data];
        NSLog(@"Connection successful");
        NSLog(@"GOOD Day My data %@",webData3);
    }
    else
    {
        NSLog(@"connection could not be made");
    }

我试过这样连接成功。

- (void)connectionDidFinishLoading:(NSURLConnection *)connection{
NSString *responseText = [[NSString alloc] initWithData:webData3 encoding: NSASCIIStringEncoding];
        NSLog(@"Response: %@", responseText);}

但是得到这样的响应 HTTP Status 500 - Request processing failed;嵌套异常是 java.lang.NullPointerException

我不明白我的错误是什么所以请给我任何想法，请告诉我我的代码有什么问题。

感谢进阶。

5xx 服务器错误

HTTP 500 内部服务器错误

一般错误消息，在遇到意外情况且没有更具体的消息合适时给出。本文出处Wikipedia : - List of HTTP status codes和 w3.org Status codes

因此需要在服务器端进行检查。这不是你的问题。
