今天后臺讓我們提交數(shù)據(jù)的時候不要提交字典，要提交Json格式的數(shù)據(jù)，于是我就把字典轉(zhuǎn)化成Json
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
發(fā)現(xiàn)上傳之后后臺不能接收，說是少了一個 { }。于是就各種百度，發(fā)現(xiàn)原來是我的請求頭設置錯了，所以找到下面這樣一個方法，重心設置請求頭，結(jié)果上傳成功：
- (void)postJsonToServer {
NSDictionary *body = @{@"UI_NAME":@"FSEAFNSEFN"};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:@"http://124.128.94.156:8000/api/UserApi/BusinessRegisterPic" parameters:nil error:nil];
req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(@"Reply JSON: %@", responseObject);
if ([responseObject isKindOfClass:[NSDictionary class]]) {
//blah blah
}
} else {
NSLog(@"Error: %@, %@, %@", error, response, responseObject);
}
}] resume];
}
