本文介绍如何使用 AFNetworking 库进行 HTTP POST 请求，并发送 JSON 数据到服务器。具体步骤包括初始化 AFHTTPClient 对象、设置参数编码为 JSON、定义请求头、创建请求参数并执行 POST 请求。

- (void)postHttpUrl:(NSString *)urlString postInfo:(NSDictionary *)info

{

if (info == nil || [info count] <= 0)

return;

NSURL * url = nil;

if (urlString == nil)

{

url = [NSURL URLWithString:@"http://data.3g.sina.com.cn/"];

}

else

{

url = [NSURL URLWithString:urlString];

}

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSString *_path= [NSString stringWithFormat:@"%@.php",[info objectForKey:@"action"]];//[

[httpClient postPath:_path parameters:info success:^(AFHTTPRequestOperation *operation,id responseObject) {

NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];

NSLog(@"Request Successful, response '%@'", responseStr);

[responseStr release];

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

NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);

}];

}

AFNetworking 如何POST一个JSON数据到服务器

NSString *pathStr=@"http://www.baidu.com" ;

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@""]];//这里要将url设置为空

httpClient.parameterEncoding = AFJSONParameterEncoding;

[httpClient setDefaultHeader:@"Accept" value:@"text/json"];

NSMutableDictionary *params=[[NSMutableDictionary alloc] init]; // 要传递的json数据是一个字典

[params setObject:UserID forKey:@"userId"];

[params setObject:[self.contDic objectForKey:@"weiboId" ] forKey:@"operateId"];

[params setObject:@"8d0ce196d0eafa27780cc3a7217de71d92474021dc0a4fc593d4f9b9eda320ca" forKey:@"key"];

// httpClient 的postPath就是上文中的pathStr，即你要访问的URL地址，这里是向服务器提交一个数据请求，

[httpClient postPath:pathStr parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

NSLog(@"data====%@",params);

NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];

NSLog(@"Request Successful, response '%@'", responseStr);

[responseStr release];

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

NSLog(@"[HTTPClient Error]: %@", error);
