AFNetWorking Crash: Invalid para

2019-08-15  本文已影响0人  OnePi

AFNetWorking出现的崩溃报错:

[Bugly]  Trapped uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: URLString' 

原因:是AFNetWorking内部有一个这个方法:

NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:method URLString:[[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString] parameters:parameters error:&serializationError];

如果URLString含有非法字符时,比如前后有空格。这个方法[NSURL URLWithString:URLString relativeToURL:self.baseURL]会返回nil,从而在方法内部的NSParameterAssert(URLString);处抛出异常,导致崩溃:

(lldb) po [[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString]
 nil
(lldb) po [NSURL URLWithString:URLString relativeToURL:self.baseURL]
 nil
(lldb) po [NSURL URLWithString:URLString]
 nil
(lldb) po URLString

解决方案:传入URLString之前,先将其编码:

URLString = [URLString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
