POST请求
// 请求的参数
NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:@"20131129", @"date", @"1", @"startRecord", @"5", @"len", @"1234567890", @"udid", @"Iphone", @"terminalType", @"213", @"cid", nil];
// 初始化Manager
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
// 不加上这句话,会报“Request failed: unacceptable content-type: text/plain”错误,因为我们要获取text/plain类型数据
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
// post请求
[manager POST:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx?" parameters:dic constructingBodyWithBlock:^(id _Nonnull formData) {
// 拼接data到请求体,这个block的参数是遵守AFMultipartFormData协议的。
} progress:^(NSProgress * _Nonnull uploadProgress) {
// 这里可以获取到目前的数据请求的进度
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
// 请求成功,解析数据
NSLog(@"%@", responseObject);
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@", dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
// 请求失败
NSLog(@"%@", [error localizedDescription]);
}];
如果是Get请求,相比Post请求,少了请求参数,然后只需将post方法改为get方法
[manager GET:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx?date=20131129&startRecord=1&len=5&udid=1234567890&terminalType=Iphone&cid=213" parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {
// 这里可以获取到目前的数据请求的进度
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
// 请求成功,解析数据
NSLog(@"%@", responseObject);
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@", dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
// 请求失败
NSLog(@"%@", [error localizedDescription]);
}];
注意:不管是Post 还是Get请求 都需要加
session.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
但不一定是text/html类型,也可能是text/plain类型,看具体情况而定。
