篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了AFNetworking 遇到错误 Code=-1016 "Request failed: unacceptable content-type: text/plain"相关的知识,希望对你有一定的参考价值。
在开发过程使用了AFNetworking库,版本2.x,先运行第一个官方例子(替换GET 后面的url即可):
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
提示Error,但其实返回的是200 OK。
Error: Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/plain"
UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x100438a90>
{ URL: http://testadmin.test.com/webservice/test } { status code: 200, headers {
Connection = "Keep-Alive";
"Content-Encoding" = gzip;
"Content-Length" = 61;
"Content-Type" = "text/plain";
Date = "Mon, 22 Feb 2016 09:19:32 GMT";
"Keep-Alive" = "timeout=10, max=10000";
Server = "SNMW1.0";
Vary = "Accept-Encoding";
} }, NSErrorFailingURLKey=http://testadmin.test.com/webservice/test,
经过查资料,是默认的AFNetworking库,不支持解析 text/plain 类型,需要简单修改源代码就可以。
打开AFURLResponseSerialization.m,找到类 AFJSONResponseSerializer,修改它的init函数:
原内容:
- (instancetype)init {
self = [super init];
if (!self) {
return nil;
}
self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];
return self;
}
修改为:
- (instancetype)init {
self = [super init];
if (!self) {
return nil;
}
self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html", @"text/json", @"text/javascript",@"text/plain", nil];
return self;
}
其实就是增加了text/plain,就可以了。
