AFHTTPSessionManager标头 [英] AFHTTPSessionManager header

问题描述

我试图通过设置HTTPAdditionalHeaders为 Content-Type设置默认标题。当我查看请求标头时，AFNetworking（v 2.0.3）将其改回。我还尝试在requestSerializer上通过setValue：forHTTPHeaderField：设置标头，但没有成功。我缺少什么？

I am trying to set a default header for "Content-Type" by setting HTTPAdditionalHeaders. When I look at the request header, AFNetworking (v 2.0.3) changes it back. I also tried to set header by setValue:forHTTPHeaderField: on the requestSerializer, but no success. What I am missing?

更新

    NSURL *URL = [NSURL URLWithString:@"http://example.com/api"];

    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    configuration.HTTPAdditionalHeaders = @{@"Content-Type": @"multipart/form-data"};

    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:URL sessionConfiguration:configuration];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

    NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
    [params setValue:@"some value" forKey:@"someKey"];

    [manager POST:@"search" parameters:params success:^(NSURLSessionDataTask *task, id responseObject) {
        NSLog(@"success");
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"error");
    }];

推荐答案

我认为AFNetworking会自动设置Content-Type，而您无法更改。要使用Content-Type multipart / form-data发送数据，请执行以下操作：

I think that AFNetworking set Content-Type automatically and you can not change it. To send data using Content-Type multipart/form-data:

NSURL *URL = [NSURL URLWithString:@"http://example.com/api"];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:URL sessionConfiguration:configuration];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
[params setValue:@"some value" forKey:@"someKey"];

[manager POST:@"search" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    //If you need to send image
    UIImage *image = [UIImage imageNamed:@"my_image.jpg"];
    [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.5) name:@"Image" fileName:@"my_image.jpg" mimeType:@"image/jpeg"];

} success:^(NSURLSessionDataTask *task, id responseObject) {

} failure:^(NSURLSessionDataTask *task, NSError *error) {

}];
