1. Code=3840
fails Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set.
" UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
原因及解決方法：
1.直接找后臺(Php)人員，主要原因在于后臺人員在處理前端上傳圖片之后對圖片處理的方法不正確導(dǎo)致。
2. Code=-1016
下面是返回的錯誤信息：
Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7fa135a68900> { URL: http://121.40.152.172:8080/sjdw/user/appLogin.do } { status code: 200, headers {

解決方法：
在 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];下面添加
manager.responseSerializer = [AFHTTPResponseSerializer serializer];。
// manager.responseSerializer= [AFHTTPResponseSerializer serializer];//使用這個將得到的是NSData
//manager.responseSerializer = [AFJSONResponseSerializer serializer];//使用這個將得到的是JSON
注:
1.后臺接收的是json格式，如：{參數(shù)：JSON},例：param={userName:13000000000,passWord:123321}
2.默認(rèn)的Response為json數(shù)據(jù)，通過添加以上代碼，返回的數(shù)據(jù)將會是一個對象，在success成功的方法塊中對responseObject進(jìn)行處理，id json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil]; 轉(zhuǎn)換成json格式。
附完整代碼：
- (IBAction)logInClick:(UIButton *)sender {
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
dict[@"userName"] = self.phoneTextField.text;
dict[@"passWord"] = self.passworldTextField.text;
NSString *jsonStr = [NSString stringWithFormat:@"%@", dict];
NSMutableDictionary *params = [NSMutableDictionary dictionary];
params[@"param"] = jsonStr;
[manager POST:[NSString stringWithFormat:@"%@/sjdw/user/appLogin.do",SERVER] parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
id json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];
NSLog(@"%@",json);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
}
未完，持續(xù)更新...
