POST請求
// 請求的參數(shù)
```
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];
```
// 不加上這句話，會報“Request failed: unacceptable content-type: text/plain”錯誤，因為我們要獲取text/plain類型數(shù)據(jù)
```
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
```
# post請求
```
[manager POST:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx?" parameters:dic constructingBodyWithBlock:^(id? _Nonnull formData) {
// 拼接data到請求體，這個block的參數(shù)是遵守AFMultipartFormData協(xié)議的。
} progress:^(NSProgress * _Nonnull uploadProgress) {
// 這里可以獲取到目前的數(shù)據(jù)請求的進(jìn)度
} success:^(NSURLSessionDataTask * _Nonnull task, id? _Nullable responseObject) {
// 請求成功，解析數(shù)據(jù)
NSLog(@"%@", responseObject);
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@", dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
// 請求失敗
NSLog(@"%@", [error localizedDescription]);
}];
```
#如果是Get請求，相比Post請求，少了請求參數(shù)，然后只需將post方法改為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) {
// 這里可以獲取到目前的數(shù)據(jù)請求的進(jìn)度
} success:^(NSURLSessionDataTask * _Nonnull task, id? _Nullable responseObject) {
// 請求成功，解析數(shù)據(jù)
NSLog(@"%@", responseObject);
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@", dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
// 請求失敗
NSLog(@"%@", [error localizedDescription]);
```
}];
注意:不管是Post 還是Get請求 都需要加
```
session.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
```
