- 使用NSURLConnection的网络请求,最好定义一个类方法,在主线程中直接调用类方法获取请求到的网络数据
- //构建类方法--请求网络
- + (void)requestData:(NSString *)urlStr
- httpMethod:(NSString *)method
- params:(NSMutableDictionary *)params
- comletionHandle:(void (^)(id result))block
- {
- //1.构建URL
- urlStr = [BASE_URL stringByAppendingString:urlStr];
- NSURL *url = [NSURL URLWithString:urlStr];
- //2.request构建
- NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
- request.timeoutInterval = 60;
- request.HTTPMethod = method;
- //判断请求方式
- if ([method isEqualToString:@"GET"]) {
- //往URL后直接拼接
- NSMutableString *paramsStr = [[NSMutableString alloc]initWithString:@"?"];
- //拼接样式
- //拼接URL---》https://api.weibo.com/2/statuses/home_timeline.json?access_token=2.00SllYeF568jxC1082c39bc40_Vqyg&username=aaa&pass=bbb
- //循环拼接参数字典
- for (int i = 0; i < params.count; i ++) {
- NSString *key = params.allKeys[i];
- NSString *value = params[key];
- //开始拼接=
- [paramsStr appendFormat:@"%@=%@",key,value];
- //拼接&符号
- //最后一个不再用&符号拼接
- if (i < params.count-1) {
- [paramsStr appendFormat:@"&"];
- }
- }
- //得到拼接后的URL(将主URL与拼接的URL 拼接在一起得到完整的URL)
- request.URL = [NSURL URLWithString:[urlStr stringByAppendingString:paramsStr]];
- }else if ([method isEqualToString:@"POST"]){
- //将参数添加到请求体中
- NSMutableString *paramsStr = [[NSMutableString alloc]initWithString:@""];
- for (int i = 0; i < params.count; i ++) {
- NSString *key = params.allKeys[i];
- NSString *value = params[key];
- //开始拼接
- [paramsStr appendFormat:@"%@=%@",key,value];
- if (i < params.count - 1) {
- [paramsStr appendFormat:@"&"];
- }
- }
- //添加到请求体中
- //将字符串转化为数据
- NSData *data = [paramsStr dataUsingEncoding:NSUTF8StringEncoding];
- request.HTTPBody = data;
- }
- //3.开始请求网络
- NSOperationQueue *queue = [[NSOperationQueue alloc]init];
- [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
- if (connectionError) {
- NSLog(@"error----%@",connectionError);
- return ;
- }
- //成功获取数据
- //开始解析数据
- id result = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
- //返回数据
- dispatch_async(dispatch_get_main_queue(), ^{
- block(result);
- });
- }];
- }
