AFNetworking的body如何傳json類型

parameters加入body中，UTF-8格式

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//發(fā)送類型(二進制格式)
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
//接收類型(二進制格式)
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
//超時時間
manager.requestSerializer.timeoutInterval = 20.0;

[manager PUT:URLString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    //查看body內(nèi)容，data轉(zhuǎn)string
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [[NSString alloc] initWithData:task.originalRequest.HTTPBody encoding:kCFStringEncodingUTF8];
        NSLog(@"成功，打印httpBody:%@", str);
    }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    //查看body內(nèi)容，data轉(zhuǎn)string
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [[NSString alloc] initWithData:task.originalRequest.HTTPBody encoding:kCFStringEncodingUTF8];
        NSLog(@"成功，打印httpBody:%@", str);
    }
}];

parameters加入body中，JSON格式

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//發(fā)送類型(JSON格式)
manager.requestSerializer = [AFJSONRequestSerializer serializer];
//接收類型(二進制格式)
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
//超時時間
manager.requestSerializer.timeoutInterval = 20.0;
//寫與不寫對最終結(jié)果不造成影響
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
//寫與不寫對最終結(jié)果不造成影響
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[manager PUT:URLString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    //查看body內(nèi)容，json解析
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [NSJSONSerialization JSONObjectWithData:task.originalRequest.HTTPBody options:0 error:nil];
        NSLog(@"成功，打印httpBody:%@", str);
    }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    //查看body內(nèi)容，json解析
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [NSJSONSerialization JSONObjectWithData:task.originalRequest.HTTPBody options:0 error:nil];
        NSLog(@"成功，打印httpBody:%@", str);
    }
}];

附：一種錯誤的寫法

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//發(fā)送類型(二進制格式)
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
//接收類型(二進制格式)
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
//超時時間
manager.requestSerializer.timeoutInterval = 20.0;
//這里一旦多加這句，就會造成400錯誤。數(shù)據(jù)解析失敗。AFNetworking沒法正常解析需發(fā)送的body
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[manager PUT:URLString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    //查看body內(nèi)容，data轉(zhuǎn)string
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [[NSString alloc] initWithData:task.originalRequest.HTTPBody encoding:kCFStringEncodingUTF8];
        NSLog(@"成功，打印httpBody:%@", str);
    }
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    //查看body內(nèi)容，data轉(zhuǎn)string
    if(task.originalRequest.HTTPBody != nil){
        NSString *str = [[NSString alloc] initWithData:task.originalRequest.HTTPBody encoding:kCFStringEncodingUTF8];
        NSLog(@"成功，打印httpBody:%@", str);
    }
}];
