ios - 请求失败 : unacceptable content-type: application/osm3s+xml

Question

我正在尝试向 OpenStreetMap api 发送请求，但我仍然没有成功。请帮我看看哪里不对。

我的方法:

NSString *url = @"http://api.openstreetmap.fr/xapi?node[name=London]";

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/osm3s+xml"];
[manager setResponseSerializer:[AFXMLParserResponseSerializer new]];

[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, NSData *responseObject) {
    NSLog(@"DATA: %@", responseObject);
    [self stopProgress];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
    self.textView.text = error.description;
    [self stopProgress];
}];

错误:

Answer 1

您的代码:

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/osm3s+xml"];

非常清楚地创建了 OpenStreetMap 拒绝的 header 。不要设置该 header :将其设置为 value like text/xml ，它被记录为正确的值。
