AFNetWorking对网络数据post请求获取数据步骤

1.创建“AFHTTPRequestOperationManager”对象；

2.设置请求参数array；

3.发送请求：

[managerPOST:url parameters:array success:^(AFHTTPRequestOperation*operation,idresponseObject) {

}failure:^(AFHTTPRequestOperation*operation,NSError*error) {

}];

例子：

AFHTTPRequestOperationManager*manager = [AFHTTPRequestOperationManagermanager];

NSDictionary*dict = @{@"name":@"zhangsan"};

NSDictionary*dict1 = @{@"name":@"wangwu"};

NSArray*array = @[dict,dict1];

//设置请求格式

manager.requestSerializer = [AFJSONRequestSerializerserializer];

//设置返回格式

manager.responseSerializer = [AFHTTPResponseSerializerserializer];

[managerPOST:@"http://localhost/postjson.php"parameters:array success:^(AFHTTPRequestOperation*operation,idresponseObject) {

NSString*result = [[NSStringalloc]initWithData:responseObjectencoding:NSUTF8StringEncoding];

NSLog(@"%@", result);

}failure:^(AFHTTPRequestOperation*operation,NSError*error) {

}];

AFNetworking请求各种类型的数据备忘笔记

AFHTTPRequestOperationManager的具体使用

1.创建管理者

AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];

2.封装请求参数

NSMutableDictionary *params = [NSMutableDictionary dictionary];

params[@"username"] = @"哈哈";

params[@"pwd"] = @"123";

3.发送请求

NSString *url = @"http://localhost:8080/LWServer/login";

[mgr POST:url parameters:params

success:^(AFHTTPRequestOperation *operation, id responseObject) {

// 请求成功的时候调用这个block

NSLog(@"请求成功---%@", responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

// 请求失败的时候调用调用这个block

NSLog(@"请求失败");

}];

// GET请求

[mgr GET:url parameters:params

success:^(AFHTTPRequestOperation \*operation, id responseObject) {

// 请求成功的时候调用这个block

NSLog(@"请求成功---%@", responseObject);

} failure:^(AFHTTPRequestOperation \*operation, NSError *error) {

// 请求失败的时候调用调用这个block

NSLog(@"请求失败");

}];
