我写了一种方法：

-(id)postAndParseJson:(NSMutableDictionary *)theDictionary action:(NSString *)action type:(NSString *)myType {

    NSString *newJSON = [theDictionary JSONRepresentation];
    NSLog(@"what to send: %@", newJSON);

    NSURL *url = [NSURL URLWithString:@"http://api.uat.ushi.cn/user/getProfile?user_id=3"];
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    NSLog(@"to url = %@",url);
    [request appendPostData:[newJSON dataUsingEncoding:NSUTF8StringEncoding]];

    [request startSynchronous];
    NSString *responseString = [request responseString];    


    NSMutableDictionary* responseDict = [responseString JSONValue];
    NSLog(@"responseString = %@",responseString);



    return responseDict;
}

该方法很简单，只需发布​​值并解析返回值，当我运行它时，我得到控制台输出：

2012-05-02 12:06:29.414 Ushi.com[775:f803] what to send: {"phone":"123456","password":"123456","user_name":"tan"}

它崩溃了！但如果我评论该行[request appendPostData:[newJSON dataUsingEncoding:NSUTF8StringEncoding]];，我将收到数据，但它也会崩溃。先感谢您...

那是因为您从服务器获得的不是有效的 JSON，而是纯 html。

问题是您的服务器不支持POST，因此它返回错误页面。
