Question

我正在使用ASIHTTPRequest和json-framework将JSON发布到rails应用程序，

问题是，当JSON到达服务器时，它用双引号括起来，

以下是我用来编码和发送JSON的代码：

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/shared_lists.json",kAPIRoot]]];

    NSString *dataString = [NSString stringWithFormat:@"shared_items=%@&shared_list=%@&facebook_id=%@",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];

    NSLog(@"%@",[NSString stringWithUTF8String:[[dataString dataUsingEncoding:NSUTF8StringEncoding] bytes]]);

    [request appendPostData:[dataString dataUsingEncoding:NSUTF8StringEncoding]];
    [request setRequestMethod:@"POST"];
    [request setDelegate:self];

    [request setDidFinishSelector:@selector(requestDone:)];
    [request setDidFailSelector:@selector(requestWentWrong:)];

    [queue addOperation:request];

正确记录为：

shared_items=[{"entity_id":"531","position":"1"},{"entity_id":"733","position":"2"},{"entity_id":"723","position":"3"},{"entity_id":"2530","position":"4"}]&shared_list={"list_id":1197}&facebook_id=-1540981104

虽然当它到达服务器时它输出为：

shared_items="[{"entity_id":"531","position":"1"},{"entity_id":"733","position":"2"},{"entity_id":"723","position":"3"},{"entity_id":"2530","position":"4"}]",shared_list="{"list_id":1197}",facebook_id="-1540981104"

如何将数组作为单个字符串包裹起来？

尝试这种方式：

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/shared_lists.json",kAPIRoot]]];

NSString *dataString = [NSString stringWithFormat:@"shared_items=%@&shared_list=%@&facebook_id=%@",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];

NSMutableData *requestBody = [[NSMutableData alloc] initWithData:[dataString dataUsingEncoding:NSUTF8StringEncoding]];
[request setRequestMethod:@"POST"];
[request setPostBody:requestBody];
[request addRequestHeader:@"Content-Type" value:@"application/json; encoding=utf-8"];

[request setUseSessionPersistence:NO];
[request setUseCookiePersistence:NO];
[request setCacheStoragePolicy:ASICacheForSessionDurationCacheStoragePolicy];

我通过手动创建JSON字符串解决了这个问题：

NSString *dataString = [NSString stringWithFormat:@"{\"shared_items\":%@,\"shared_list\":%@,\"facebook_id\":%@}",[sharedItems JSONRepresentation],[sharedList JSONRepresentation],facebookID];

ASIHTTPRequest将JSON包装在引号中
