我创建了一个子类，AFHTTPClient并试图将一些 JSON 参数发送到服务器。
但是，服务器以预期的内容类型响应
{(
"text/json",
"application/json",
"text/javascript"
)}, got application/xml
如果您使用的是 AFHTTPClient，请将 parameterEncoding 属性设置为 AFJSONParameterEncoding。该 HTTP 客户端上带有参数参数的任何方法现在都将传递的对象编码为 JSON 字符串，并适当地设置 HTTP 正文和 Content-Type 标头。
我已经在这里完成了，但服务器似乎无法识别内容标题。有谁知道潜在的解决方案？
这是方法：
- (void)getCompanyDataWithString:(NSString*)companySearchQuery
finish:(LBMarkitAPIRequestCompletionBlock)finishBlock
{
[self registerHTTPOperationClass:[AFJSONRequestOperation class]];
[self setParameterEncoding:AFJSONParameterEncoding];
NSDictionary *params = [NSDictionary dictionaryWithObject:
companySearchQuery forKey:@"input"];
NSMutableURLRequest *searchQueryRequest = [self requestWithMethod:@"GET"
path:kMarkitCompanyURL parameters:params];
AFJSONRequestOperation *searchRequestOperation = [AFJSONRequestOperation
JSONRequestOperationWithRequest:searchQueryRequest
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id json)
{
NSLog(@"Response: %@", response);
NSLog(@"JSON: %@",json);
NSMutableArray *results = [NSMutableArray array];
NSError *anError = [[NSError alloc] init];
if ([json objectForKey:@"Message"])
{
NSString *message = [json objectForKey:@"Message"];
anError = [[NSError alloc] initWithDomain:message
code:100
userInfo:nil];
}
// Need some error handling code here
for (id item in json)
{
NSString *aName = [item objectForKey:@"Name"];
NSString *aSymbol = [item objectForKey:@"Symbol"];
NSString *anExchange = [item objectForKey:@"Exchange"];
LBCompany *aCompany = [[LBCompany alloc] initWithName:aName
Symbol:aSymbol Exchange:anExchange];
[results addObject:aCompany];
}
// Need to run the passed in block after JSON
// Request Operation succeeds
finishBlock(results,anError);
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response,
NSError *error, id JSON)
{
NSLog(@"request failed: %@",[error localizedDescription]);
NSLog(@"Response: %@",response);
NSLog(@"JSON: %@",JSON);
}];
[searchRequestOperation start];
NSLog(@"JSON operation started");
}
