在 Google App Engine Python API 中获取原始发布数据
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')
I am trying to get raw data sent as post to Google App engine, using self.request.get('content'), but in vain. It returns empty. I am sure the data is being sent from the client, coz I checked with another simple server code.
Any idea what I am doing wrong? I am using the following code on the client side generating the POST call (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];
The server side code is:
class userResult(webapp.RequestHandler):
def __init__(self):
self.qNo = 1
def post(self):
return self.request.get('json')

self.request.get('content') 将为您提供使用参数名称“content”发送的数据。如果您想要原始帖子数据，请使用 self.request.body。
self.request.get('content')will give you data sent with the argument name 'content'. If you want the raw post data, useself.request.body.尝试使用
application/x-www-form-urlencoded以外的内容类型提交 POST 数据，这是浏览器提交表单时的默认类型。如果您使用不同的内容类型，原始帖子数据将位于 self.request.body 中，如 Wooble 建议的那样。如果这实际上来自 HTML 表单，您可以将
enctype属性添加到Try submitting the POST data with a content type other than
application/x-www-form-urlencoded, which is the default when a form is submitted by a browser. If you use a different content type, the raw post data will be inself.request.body, as Wooble suggested.If this is actually coming from an HTML form, you can add the
enctypeattribute to the<form>element to change the encoding used by the browser. Try something likeenctype="application/octet-stream".
