iOS-95-網路請求方式彙總（包含AFNetworking、NSMutableURLRequest）
阿新 • • 發佈：2019-02-13
文章包涵AFNetworking、NSMutableURLRequest兩種請求方式：get、post、上傳圖片、解決上傳base64編碼圖片過長問題（使用【2、post 第一種配置】即可解決）
比如報錯：err:Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: too long (414)"
一、AFNetworking篇
1、get
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; //申明返回的結果是json型別 manager.responseSerializer=[AFJSONResponseSerializer serializer]; //申明請求的資料是json型別 manager.requestSerializer=[AFJSONRequestSerializer serializer]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; // [self.HUD showLoading]; //請求時帶請求頭 [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; // 設定header NSString *header = @"自定義header格式"; [manager.requestSerializer setValue:header forHTTPHeaderField:kHeaderKey]; __weak typeof(self) weakSelf = self; [manager GET:url parameters:nil progress:^(NSProgress * _Nonnull uploadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"+++++%@",result); NSDictionary *dic = [weakSelf dictionaryWithJsonString:result]; } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { }];
2、post 第一種配置
NSString *url = @"http://···········"; // 特別說明：像base64編碼後的圖片比較大，使用這種方式即可 NSDictionary *paramDic = @{ @"base64Str":imageStr, @"number":@"12344", @"name":name, @"key":@"key", }; AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; __weak typeof(self) weakself = self; manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/plain",@"image/png",nil]; [self.HUD showLoading]; [manager POST:url parameters:paramDic success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) { NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"+++++%@",result); NSDictionary *object = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil]; } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"++++++ %@",error); }];
3、post 第二種配置。 與【2】基本一致
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; //申明返回的結果是json型別 manager.responseSerializer=[AFJSONResponseSerializer serializer]; //申明請求的資料是json型別 manager.requestSerializer=[AFJSONRequestSerializer serializer]; //請求時帶請求頭 __weak typeof(self) weakself = self; [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [manager POST:URL parameters:nil progress:^(NSProgress * _Nonnull uploadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { }];
4、post 上傳圖片
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//申明返回的結果是json型別
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/plain",@"image/png",nil];
//提交資料及檔案（圖片、其他格式檔案）
[manager POST:kAddFeedbackURL parameters:param constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// 在此處新增要傳送的檔案 （原理：block回撥）
[formData appendPartWithFileData:nil name:nil fileName:nil mimeType:@"application/octet-stream; charset=UTF-8"]; //image/jpeg
[formData appendPartWithFileData:photoData2 name:@"img2" fileName:fileName2 mimeType:@"image/jpeg"];
}
progress:^(NSProgress * _Nonnull uploadProgress) {
// 進度條
NSLog(@"service progress...");
}
success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (responseObject != nil) {
NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
}
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"POST Error: %@", error.description);
}
];二、原生方法：NSMutableURLRequest、NSURLSessionDataTask
// 1.建立一個網路路徑
NSURL *url = [NSURL URLWithString:@"http://----"];
// 2.建立一個網路請求，分別設定請求方法、請求引數
NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
NSString *args = [NSString stringWithFormat:@"memberId=%@&content=%@",PhoneNumber,content];
request.HTTPBody = [args dataUsingEncoding:NSUTF8StringEncoding];
// 設定header
NSString *header = @"自定義header格式";
[request setValue:header forHTTPHeaderField:kHeaderKey];
// 3.獲得會話物件
NSURLSession *session = [NSURLSession sharedSession];
// 4.根據會話物件，建立一個Task任務
__weak typeof(self) weakSelf = self;
[self.HUD showLoading];
NSURLSessionDataTask *sessionDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
NSLog(@"從伺服器獲取到資料");
/*
對從伺服器獲取到的資料data進行相應的處理.
*/
// NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:(NSJSONReadingMutableLeaves) error:nil];
NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"+++++%@",result);
NSDictionary *dic = [weakSelf dictionaryWithJsonString:result];
[self performSelectorOnMainThread:@selector(handleResponeDetailInfo:) withObject:dic waitUntilDone:NO];
}];
//5.最後一步，執行任務，(resume也是繼續執行)。
[sessionDataTask resume];
