在Google App Engine Python API中获取原始发布数据

Question

我正在尝试使用self.request.get('content')将原始数据作为帖子发送到Google App引擎,但是徒劳无功.它返回空.我确信数据是从客户端发送的,因为我检查了另一个简单的服务器代码.

知道我做错了什么吗？我在客户端使用以下代码生成POST调用(objective-c/cocoa-touch)

NSMutableArray *array = [[NSMutableArray alloc] init];
    NSMutableDictionary *diction = [[NSMutableDictionary alloc] init];
    NSString *tempcurrentQuestion = [[NSString alloc] initWithFormat:@"%d", (questionNo+1)];
    NSString *tempansweredOption = [[NSString alloc] initWithFormat:@"%d", (answeredOption)];       

    [diction setValue:tempcurrentQuestion forKey:@"questionNo"];
    [diction setValue:tempansweredOption forKey:@"answeredOption"];
    [diction setValue:country forKey:@"country"];

    [array addObject:diction];
    NSString *post1 = [[CJSONSerializer serializer] serializeObject:array];


    NSString *post = [NSString stringWithFormat:@"json=%@", post1];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];  
    NSLog(@"Length: %d", [postData length]);

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

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];  
    [request setURL:[NSURL URLWithString:@"http://localhost:8080/userResult/"]];  
    [request setHTTPMethod:@"POST"];  
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];  
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];  
    [request setHTTPBody:postData];
    questionsFlag = FALSE;
    [[NSURLConnection alloc] initWithRequest:request delegate:self];

服务器端代码是:

class userResult(webapp.RequestHandler):
def __init__(self):
    self.qNo = 1
def post(self):
    return self.request.get('json')

self.request.get('content')将为您提供以参数名称'content'发送的数据.如果您需要原始发布数据,请使用self.request.body.
