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。
